+The kernel provides the following general purpose memory allocators:
+kmalloc(), kzalloc(), kcalloc(), and vmalloc(). Please refer to the API
+documentation for further information about them.
+
+The preferred form for passing a size of a struct is the following:
+
+ p = kmalloc(sizeof(*p), ...);
+
+The alternative form where struct name is spelled out hurts readability and
+introduces an opportunity for a bug when the pointer variable type is changed
+but the corresponding sizeof that is passed to a memory allocator is not.

+Casting the return value which is a void pointer is redundant. The conversion
+from void pointer to any other pointer type is guaranteed by the C programming
+language.

+An ad-hoc collection of notes on IA64 MCA and INIT processing. Feel
+free to update it with notes about any area that is not clear.
+
+---
+
+MCA/INIT are completely asynchronous. They can occur at any time, when
+the OS is in any state. Including when one of the cpus is already
+holding a spinlock. Trying to get any lock from MCA/INIT state is
+asking for deadlock. Also the state of structures that are protected
+by locks is indeterminate, including linked lists.
+
+---
+
+The complicated ia64 MCA process. All of this is mandated by Intel's
+specification for ia64 SAL, error recovery and and unwind, it is not as
+if we have a choice here.
+
+* MCA occurs on one cpu, usually due to a double bit memory error.
+ This is the monarch cpu.
+
+* SAL sends an MCA rendezvous interrupt (which is a normal interrupt)
+ to all the other cpus, the slaves.
+
+* Slave cpus that receive the MCA interrupt call down into SAL, they
+ end up spinning disabled while the MCA is being serviced.
+
+* If any slave cpu was already spinning disabled when the MCA occurred
+ then it cannot service the MCA interrupt. SAL waits ~20 seconds then
+ sends an unmaskable INIT event to the slave cpus that have not
+ already rendezvoused.
+
+* Because MCA/INIT can be delivered at any time, including when the cpu
+ is down in PAL in physical mode, the registers at the time of the
+ event are _completely_ undefined. In particular the MCA/INIT
+ handlers cannot rely on the thread pointer, PAL physical mode can
+ (and does) modify TP. It is allowed to do that as long as it resets
+ TP on return. However MCA/INIT events expose us to these PAL
+ internal TP changes. Hence curr_task().
+
+* If an MCA/INIT event occurs while the kernel was running (not user
+ space) and the kernel has called PAL then the MCA/INIT handler cannot
+ assume that the kernel stack is in a fit state to be used. Mainly
+ because PAL may or may not maintain the stack pointer internally.
+ Because the MCA/INIT handlers cannot trust the kernel stack, they
+ have to use their own, per-cpu stacks. The MCA/INIT stacks are
+ preformatted with just enough task state to let the relevant handlers
+ do their job.
+
+* Unlike most other architectures, the ia64 struct task is embedded in
+ the kernel stack[1]. So switching to a new kernel stack means that
+ we switch to a new task as well. Because various bits of the kernel
+ assume that current points into the struct task, switching to a new
+ stack also means a new value for current.
+
+* Once all slaves have rendezvoused and are spinning disabled, the
+ monarch is entered. The monarch now tries to diagnose the problem
+ and decide if it can recover or not.
+
+* Part of the monarch's job is to look at the state of all the other
+ tasks. The only way to do that on ia64 is to call the unwinder,
+ as mandated by Intel.
+
+* The starting point for the unwind depends on whether a task is
+ running or not. That is, whether it is on a cpu or is blocked. The
+ monarch has to determine whether or not a task is on a cpu before it
+ knows how to start unwinding it. The tasks that received an MCA or
+ INIT event are no longer running, they have been converted to blocked
+ tasks. But (and its a big but), the cpus that received the MCA
+ rendezvous interrupt are still running on their normal kernel stacks!
+
+* To distinguish between these two cases, the monarch must know which
+ tasks are on a cpu and which are not. Hence each slave cpu that
+ switches to an MCA/INIT stack, registers its new stack using
+ set_curr_task(), so the monarch can tell that the _original_ task is
+ no longer running on that cpu. That gives us a decent chance of
+ getting a valid backtrace of the _original_ task.
+
+* MCA/INIT can be nested, to a depth of 2 on any cpu. In the case of a
+ nested error, we want diagnostics on the MCA/INIT handler that
+ failed, not on the task that was originally running. Again this
+ requires set_curr_task() so the MCA/INIT handlers can register their
+ own stack as running on that cpu. Then a recursive error gets a
+ trace of the failing handler's "task".
+
+[1] My (Keith Owens) original design called for ia64 to separate its
+ struct task and the kernel stacks. Then the MCA/INIT data would be
+ chained stacks like i386 interrupt stacks. But that required
+ radical surgery on the rest of ia64, plus extra hard wired TLB
+ entries with its associated performance degradation. David
+ Mosberger vetoed that approach. Which meant that separate kernel
+ stacks meant separate "tasks" for the MCA/INIT handlers.
+
+---
+
+INIT is less complicated than MCA. Pressing the nmi button or using
+the equivalent command on the management console sends INIT to all
+cpus. SAL picks one one of the cpus as the monarch and the rest are
+slaves. All the OS INIT handlers are entered at approximately the same
+time. The OS monarch prints the state of all tasks and returns, after
+which the slaves return and the system resumes.
+
+At least that is what is supposed to happen. Alas there are broken
+versions of SAL out there. Some drive all the cpus as monarchs. Some
+drive them all as slaves. Some drive one cpu as monarch, wait for that
+cpu to return from the OS then drive the rest as slaves. Some versions
+of SAL cannot even cope with returning from the OS, they spin inside
+SAL on resume. The OS INIT code has workarounds for some of these
+broken SAL symptoms, but some simply cannot be fixed from the OS side.
+
+---
+
+The scheduler hooks used by ia64 (curr_task, set_curr_task) are layer
+violations. Unfortunately MCA/INIT start off as massive layer
+violations (can occur at _any_ time) and they build from there.
+
+At least ia64 makes an attempt at recovering from hardware errors, but
+it is a difficult problem because of the asynchronous nature of these
+errors. When processing an unmaskable interrupt we sometimes need
+special code to cope with our inability to take any locks.
+
+---
+
+How is ia64 MCA/INIT different from x86 NMI?
+
+* x86 NMI typically gets delivered to one cpu. MCA/INIT gets sent to
+ all cpus.
+
+* x86 NMI cannot be nested. MCA/INIT can be nested, to a depth of 2
+ per cpu.
+
+* x86 has a separate struct task which points to one of multiple kernel
+ stacks. ia64 has the struct task embedded in the single kernel
+ stack, so switching stack means switching task.
+
+* x86 does not call the BIOS so the NMI handler does not have to worry
+ about any registers having changed. MCA/INIT can occur while the cpu
+ is in PAL in physical mode, with undefined registers and an undefined
+ kernel stack.
+
+* i386 backtrace is not very sensitive to whether a process is running
+ or not. ia64 unwind is very, very sensitive to whether a process is
+ running or not.
+
+---
+
+What happens when MCA/INIT is delivered what a cpu is running user
+space code?
+
+The user mode registers are stored in the RSE area of the MCA/INIT on
+entry to the OS and are restored from there on return to SAL, so user
+mode registers are preserved across a recoverable MCA/INIT. Since the
+OS has no idea what unwind data is available for the user space stack,
+MCA/INIT never tries to backtrace user space. Which means that the OS
+does not bother making the user space process look like a blocked task,
+i.e. the OS does not copy pt_regs and switch_stack to the user space
+stack. Also the OS has no idea how big the user space RSE and memory
+stacks are, which makes it too risky to copy the saved state to a user
+mode stack.
+
+---
+
+How do we get a backtrace on the tasks that were running when MCA/INIT
+was delivered?
+
+mca.c:::ia64_mca_modify_original_stack(). That identifies and
+verifies the original kernel stack, copies the dirty registers from
+the MCA/INIT stack's RSE to the original stack's RSE, copies the
+skeleton struct pt_regs and switch_stack to the original stack, fills
+in the skeleton structures from the PAL minstate area and updates the
+original stack's thread.ksp. That makes the original stack look
+exactly like any other blocked task, i.e. it now appears to be
+sleeping. To get a backtrace, just start with thread.ksp for the
+original task and unwind like any other sleeping task.
+
+---
+
+How do we identify the tasks that were running when MCA/INIT was
+delivered?
+
+If the previous task has been verified and converted to a blocked
+state, then sos->prev_task on the MCA/INIT stack is updated to point to
+the previous task. You can look at that field in dumps or debuggers.
+To help distinguish between the handler and the original tasks,
+handlers have _TIF_MCA_INIT set in thread_info.flags.
+
+The sos data is always in the MCA/INIT handler stack, at offset
+MCA_SOS_OFFSET. You can get that value from mca_asm.h or calculate it
+as KERNEL_STACK_SIZE - sizeof(struct pt_regs) - sizeof(struct
+ia64_sal_os_state), with 16 byte alignment for all structures.
+
+Also the comm field of the MCA/INIT task is modified to include the pid
+of the original task, for humans to use. For example, a comm field of
+'MCA 12159' means that pid 12159 was running when the MCA was
+delivered.

+AC97 Quirk Option
+=================
+
+The ac97_quirk option is used to enable/override the workaround for
+specific devices on drivers for on-board AC'97 controllers like
+snd-intel8x0. Some hardware have swapped output pins between Master
+and Headphone, or Surround (thanks to confusion of AC'97
+specifications from version to version :-)
+
+The driver provides the auto-detection of known problematic devices,
+but some might be unknown or wrongly detected. In such a case, pass
+the proper value with this option.
+
+The following strings are accepted:
+ - default Don't override the default setting
+ - disable Disable the quirk
+ - hp_only Bind Master and Headphone controls as a single control
+ - swap_hp Swap headphone and master controls
+ - swap_surround Swap master and surround controls
+ - ad_sharing For AD1985, turn on OMS bit and use headphone
+ - alc_jack For ALC65x, turn on the jack sense mode
+ - inv_eapd Inverted EAPD implementation
+ - mute_led Bind EAPD bit for turning on/off mute LED
+
+For backward compatibility, the corresponding integer value -1, 0,
+... are accepted, too.
+
+For example, if "Master" volume control has no effect on your device
+but only "Headphone" does, pass ac97_quirk=hp_only module option.

- * Packet writing layer for ATAPI and SCSI CD-R, CD-RW, DVD-R, and
- * DVD-RW devices (aka an exercise in block layer masturbation)
- *
- *
- * TODO: (circa order of when I will fix it)
- * - Only able to write on CD-RW media right now.
- * - check host application code on media and set it in write page
- * - interface for UDF <-> packet to negotiate a new location when a write
- * fails.
- * - handle OPC, especially for -RW media
+ * Packet writing layer for ATAPI and SCSI CD-RW, DVD+RW, DVD-RW and
+ * DVD-RAM devices.
*
* Theory of operation:
*
- * We use a custom make_request_fn function that forwards reads directly to
- * the underlying CD device. Write requests are either attached directly to
- * a live packet_data object, or simply stored sequentially in a list for
- * later processing by the kcdrwd kernel thread. This driver doesn't use
- * any elevator functionally as defined by the elevator_s struct, but the
- * underlying CD device uses a standard elevator.
+ * At the lowest level, there is the standard driver for the CD/DVD device,
+ * typically ide-cd.c or sr.c. This driver can handle read and write requests,
+ * but it doesn't know anything about the special restrictions that apply to
+ * packet writing. One restriction is that write requests must be aligned to
+ * packet boundaries on the physical media, and the size of a write request
+ * must be equal to the packet size. Another restriction is that a
+ * GPCMD_FLUSH_CACHE command has to be issued to the drive before a read
+ * command, if the previous command was a write.
*
- * This strategy makes it possible to do very late merging of IO requests.
- * A new bio sent to pkt_make_request can be merged with a live packet_data
- * object even if the object is in the data gathering state.
+ * The purpose of the packet writing driver is to hide these restrictions from
+ * higher layers, such as file systems, and present a block device that can be
+ * randomly read and written using 2kB-sized blocks.
+ *
+ * The lowest layer in the packet writing driver is the packet I/O scheduler.
+ * Its data is defined by the struct packet_iosched and includes two bio
+ * queues with pending read and write requests. These queues are processed
+ * by the pkt_iosched_process_queue() function. The write requests in this
+ * queue are already properly aligned and sized. This layer is responsible for
+ * issuing the flush cache commands and scheduling the I/O in a good order.
+ *
+ * The next layer transforms unaligned write requests to aligned writes. This
+ * transformation requires reading missing pieces of data from the underlying
+ * block device, assembling the pieces to full packets and queuing them to the
+ * packet I/O scheduler.
+ *
+ * At the top layer there is a custom make_request_fn function that forwards
+ * read requests directly to the iosched queue and puts write requests in the
+ * unaligned write queue. A kernel thread performs the necessary read
+ * gathering to convert the unaligned writes to aligned writes and then feeds
+ * them to the packet I/O scheduler.

+ * Watchdog Timer Configuration
+ *
+ * The function of the watchdog timer is to reset the system automatically
+ * and is defined at I/O port 0120H and 0121H. To enable the watchdog timer
+ * and allow the system to reset, write appropriate values from the table
+ * below to I/O port 0120H and 0121H. To disable the timer, write a zero
+ * value to I/O port 0121H for the system to stop the watchdog function.
+ *
+ * The following describes how the timer should be programmed (according to
+ * the vendor documentation)
+ *
+ * Enabling Watchdog:
+ * MOV AX,000AH (enable, phase I)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000BH (enable, phase II)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000nH (set multiplier n, from 1-4)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000mH (set base timer m, from 0-F)
+ * MOV DX,0121H
+ * OUT DX,AX
+ *
+ * Reset timer:
+ * MOV AX,000mH (same as set base timer, above)
+ * MOV DX,0121H
+ * OUT DX,AX
+ *
+ * Disabling Watchdog:
+ * MOV AX,0000H (a zero value)
+ * MOV DX,0120H
+ * OUT DX,AX
+ *
+ * Watchdog timeout configuration values:
+ * N
+ * M | 1 2 3 4

+ * ip_conntrack_pptp.c - Version 3.0
+ *
+ * Connection tracking support for PPTP (Point to Point Tunneling Protocol).
+ * PPTP is a a protocol for creating virtual private networks.
+ * It is a specification defined by Microsoft and some vendors
+ * working with Microsoft. PPTP is built on top of a modified
+ * version of the Internet Generic Routing Encapsulation Protocol.
+ * GRE is defined in RFC 1701 and RFC 1702. Documentation of
+ * PPTP can be found in RFC 2637
+ *
+ * (C) 2000-2005 by Harald Welte <laforge@gnumonks.org>
+ *
+ * Development of this code funded by Astaro AG (http://www.astaro.com/)
+ *
+ * Limitations:
+ * - We blindly assume that control connections are always
+ * established in PNS->PAC direction. This is a violation
+ * of RFFC2673
+ * - We can only support one single call within each session
+ *
+ * TODO:
+ * - testing of incoming PPTP calls
+ *
+ * Changes:
+ * 2002-02-05 - Version 1.3
+ * - Call ip_conntrack_unexpect_related() from
+ * pptp_destroy_siblings() to destroy expectations in case
+ * CALL_DISCONNECT_NOTIFY or tcp fin packet was seen
+ * (Philip Craig <philipc@snapgear.com>)
+ * - Add Version information at module loadtime
+ * 2002-02-10 - Version 1.6
+ * - move to C99 style initializers
+ * - remove second expectation if first arrives
+ * 2004-10-22 - Version 2.0
+ * - merge Mandrake's 2.6.x port with recent 2.6.x API changes
+ * - fix lots of linear skb assumptions from Mandrake's port
+ * 2005-06-10 - Version 2.1
+ * - use ip_conntrack_expect_free() instead of kfree() on the
+ * expect's (which are from the slab for quite some time)
+ * 2005-06-10 - Version 3.0
+ * - port helper to post-2.6.11 API changes,
+ * funded by Oxcoda NetBox Blue (http://www.netboxblue.com/)
+ * 2005-07-30 - Version 3.1
+ * - port helper to 2.6.13 API changes

+ *
+ * It has an optional key field, which may help us distinguishing two

+ * PPTP is built on top of a modified version of GRE, and has a mandatory

+ * NAT support for PPTP (Point to Point Tunneling Protocol).
+ * PPTP is a a protocol for creating virtual private networks.
+ * It is a specification defined by Microsoft and some vendors
+ * working with Microsoft. PPTP is built on top of a modified
+ * version of the Internet Generic Routing Encapsulation Protocol.
+ * GRE is defined in RFC 1701 and RFC 1702. Documentation of

+ *
+ * Development of this code funded by Astaro AG (http://www.astaro.com/)
+ *
+ * TODO: - NAT to a unique tuple, not to TCP source port
+ * (needs netfilter tuple reservation)
+ *
+ * Changes:
+ * 2002-02-10 - Version 1.3
+ * - Use ip_nat_mangle_tcp_packet() because of cloned skb's
+ * in local connections (Philip Craig <philipc@snapgear.com>)
+ * - add checks for magicCookie and pptp version
+ * - make argument list of pptp_{out,in}bound_packet() shorter
+ * - move to C99 style initializers
+ * - print version number at module loadtime
+ * 2003-09-22 - Version 1.5
+ * - use SNATed tcp sourceport as callid, since we get called before
+ * TCP header is mangled (Philip Craig <philipc@snapgear.com>)
+ * 2004-10-22 - Version 2.0
+ * - kernel 2.6.x version
+ * 2005-06-10 - Version 3.0
+ * - kernel >= 2.6.11 version,
+ * funded by Oxcoda NetBox Blue (http://www.netboxblue.com/)

+ * ip_nat_proto_gre.c - Version 2.0
+ *
+ * NAT protocol helper module for GRE.
+ *
+ * GRE is a generic encapsulation protocol, which is generally not very
+ * suited for NAT, as it has no protocol-specific part as port numbers.
+ *
+ * It has an optional key field, which may help us distinguishing two
+ * connections between the same two hosts.
+ *
+ * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
+ *
+ * PPTP is built on top of a modified version of GRE, and has a mandatory
+ * field called "CallID", which serves us for the same purpose as the key
+ * field in plain GRE.
+ *
+ * Documentation about PPTP can be found in RFC 2637
+ *
+ * (C) 2000-2005 by Harald Welte <laforge@gnumonks.org>
+ *
+ * Development of this code funded by Astaro AG (http://www.astaro.com/)
