smp_send_reschedule_all() is unused in 2.5 and can be eliminated.

It is unused and not needed

In ide_register_subdriver() create drive->proc entries only if driver is
not idedefault_driver.

[ There won't be /proc/ide/hdX/capacity for devices attached
  to idedefault_driver now, it reported 0x7fffffff previously. ]

Do not create drive->proc entries in create_proc_ide_drives(), they are
added later in ide_register_subdriver().

A recent change to the megaraid driver to fix some memset calls resulted
in overflowing the arrays being cleared and causing a system panic.
This patch fixes the problem by making sure that the arrays being
cleared are dimensioned to the correct size.  The patch has been tested
on osdl's stp machines that have megaraid controllers.

Here we really want CONFIG_ALL_PPC, since these headers are only valid
for PPC Mac machines (barf: badly named config option).

One of those very-hard-to-track-down, trivial-to-fix kind of problems:
without this patch, TCP roundtrip time measurements will corrupt the
routing cache's RTT estimates under heavy network load (the bug causes
RTAX_RTT to go negative, but since its type is u32, you end up with a
huge positive value...).  From there on, later TCP connections quickly
will go south.

The typo was introduced 8 months ago in v1.29 of the file by the patch
entitled "Cleanup DST metrics and abstrct MSS/PMTU further".

signal.h uses spinlock_t now so it needs to include spinlock.h.
Without this compilation failes on PPC.

This patch fixes an unload crash when no PCI drivers are loaded.

This adds a new interface to kernel/signal.c which allows signals to be
sent using preallocated sigqueue structures.  It also modifies
kernel/posix-timers.c to use this interface.

The current timer code may fail to deliver a timer expiry signal if
there are no sigqueue structures available at the time of the expiry.
The Posix specification is clear that the signal queuing resource should
be allocated at timer_create time.  This allows the error to be returned
to the application rather than silently losing the signal.

This patch does not change the sigqueue structure allocation policy.  I
hope to revisit that in another patch.

Here is the definition for the new interface:

struct sigqueue *sigqueue_alloc(void)
	Preallocate a sigqueue structure for use with the functions
	described below.

void sigqueue_free(struct sigqueue *q)
	Free a preallocated sigqueue structure.  If the sigqueue
	structure being freed is still queued, it will be removed
	from the queue.  I currently leave the signal pending.
	It may be delivered without the siginfo structure.

int send_sigqueue(int sig, struct sigqueue *q, struct task_struct *p)
	This function is equivalent to send_sig_info().  It queues
	a signal to the specified thread using  the supplied sigqueue
	structure.  The caller is expected to fill in the siginfo_t
	which is part of the sigqueue structure.

int send_group_sigqueue(int sig, struct sigqueue *q, struct task_struct *p)
	This function is equivalent to send_group_sig_info().  It queues
	the signal to a process allowing the system to select which thread
	will receive the signal in a multi-threaded process.
	Again, the sigqueue structure is used to queue the signal.

Both send_sigqueue() and send_group_sigqueue() return 0 if the signal
is queued. They return 1 if the signal was not queued because the
process is ignoring the signal.

Both versions include code to increment the si_overrun count if the
sigqueue entry is for a Posix timer and they are called while the
sigqueue entry is still queued.  Yes, I know that the current code
doesn't rearm the timer until the signal is delivered.  Having this
extra bit of code doesn't do any harm, and I plan to use it.

These routines do not check if there already is a legacy (non-realtime)
signal pending.  They always queue the signal.  This requires that
collect_signal() always checks if there is another matching siginfo
before clearing the signal bit.

SysV sem operations that involve multiple semaphores can fail in the
middle, and then sempid (pid of the last successful operation) must be
restored.  This happens with "sempid >>= 16" - broken due to the 32-bit pid
values.  The attached patch fixes that by reordering the updates of the
semaphore fields.

Additionally, the patch fixes the corruption of the sempid value that occurs
if a wait-for-zero operation fails.

The patch is more than two years old, and was in -dj and -ak kernels.
