Some time ago, a patch was merged that removed pci_save_state() and
pci_restore_state() from various ALSA drivers. That patch also added
pci_restore_state() to sound/core/init.c but didn't add pci_save_state()
anywhere. This is needed since the core pci handling doesn't do this for
us anymore.

My laptop doesn't resume (gets what I assume is an ACPI timeout and
hangs solid) without this small obvious patch.

We have to load the bigkernel second TLB entry on
secondary processors before we move over the use
the kernel trap table.  Otherwise we can take a
TLB miss somewhere in the post-4MB area and the
TLB handler is not prepared to service that.

The case that usually occurs is the prom_set_trap_table
call made by trampoline.S, since p1275buf usually sits
very near the end of the kernel image.  It worked by
luck most of the time as long as p1275buf sits within
a single page since earlier code running in trampoline.S
forced that TLB entry to be loaded by the OBP TLB miss
handler.

This was not fun to figure out.

Patch from Ben Dooks

A simple divide is not enough for the s3c2410 default
timer code, due to most clocks not being a nice multiple
of usecs.

This update changes the calculation of the usec to use
multipliers and shifts to effect a fast divide by a non-integer
number.

proc_pid_status dereferences pointers in the task structure even if the
task is already dead.  This is probably the reason for the oops described
in

http://bugme.osdl.org/show_bug.cgi?id=3812

The attached patch removes the pointer dereferences by using pid_alive()
for testing that the task structure contents is still valid before
dereferencing them.  The task structure itself is guaranteed to be valid -
we hold a reference count.

Timothy Lee reports:

Hardware: CyberBlade/i1 on VIA Epia-800

Problem Description:  When the framebuffer is set to 16 bpp, console's text
colours are incorrect.  For example, white becomes yellow, black becomes blue, etc.

Steps to reproduce:
1. Load tridentfb
2. Use "setterm -n -depth 16" to request 16 bpp framebuffer

The problem arose from the fact that each psuedo palette entry should be
32-bit in size, even under 16-bit display mode.

This patch avoids a deadlock on rtnl_sem in smc_close() when bringing down
an smc91x interface.  The semaphore is already held by devinet_ioctl() and
the pending work queue contains linkwatch_event() (scheduled by
netif_carrier_off()) which also wants rtnl_sem hence it is unsafe to call
flush_scheduled_work().

The solution is to track whether we have any pending work of our own and
wait for that instead of flushing the entire queue.

I also fixed a typo 'ence' -> 'Hence' and renamed smc_detect_phy to
smc_phy_detect in order to follow the same pattern as the other smc_phy_*
functions.

We check need_resched() _before_ disabling preemption.  This opens up the
following scenario:

 swapper:	!need_resched()
 [IRQ context]
		wakes up a task
		marks idle task as need-resched

 swapper:	acpi_processor_idle(); // sleeps until next irq

instant 1msec latency introduced...

normally default_idle() is safe because it re-checks need_resched with
interrupts disabled before it truly halts the CPU.  But
acpi_processor_idle() doesnt seem to be doing this!  Your trace clearly
shows a missed preemption due to ACPI.  I'm wondering why no-one has
triggered this before, it's a really bad bug that should be fixed in
2.6.10.

For reasons which escape me, blockdev_get_blocks() is returning -EIO if the
mapping request straddles the end of the disk.  This causes reads which
straddle end-of-disk to return -EIO.

Fix it up so that it correctly trims the returned result down to match the
size of the device, for both reads and writes.

If a write attempt is fully beyond end-of-device then return -EIO.  We never
get this far anyway, because generic_write_checks() will return -ENOSPC if all
of the write lies outside a blockdev's i_size.
