Since we do not set the task state to TASK_INTERRUPTIBLE, we busy loop.

On larger SMP this can actually result in a lockup due to the way
migration thread initalisation is done (nr_cpus threads are created
and they all busy loop until the scheduler evenly distributes them,
one on each cpu. With this rogue thread busy looping things can become
unbalanced and the migration threads never distribute themselves onto
all cpus).

include/linux/seq_file.h uses memcpy and struct semaphore and so should
include the relevant files.

(eg ppc64) where foo points to a function descriptor and .foo is
the address of the actual function.

ide-dma incorrectly only clears high memory support if the verbose dma
disabling is called, it should clear it for the non-verbose too.

Hi Linus,

Oops, SMP non-ACPI doesn't compile with the previous ACPI update. This
fixes that.

Take ->i_sem in all callers of notify_change().

ieee1394 updates:
  - New drivers: eth1394, admtp
  - nodemgr cleanup
  - Fixes for ohci
  - fixed for node probes
  - small misc performance fixes
  - New /proc interface for subsystem, node listing, and dv1394

ext3 was missed - the removal of the BKL in notify_change
means that the filesytem fails quite quickly on SMP in -pre2.
Sorry, I should have spotted that when the patch floated past.

ACPI PCI IRQ improvements (Dominik Brodowski and Paul D)
Wakeup fix (Pavel Machek)

Better IRQ routing
ACPI 2.0-enumerated processor perf state support
ACPI poweroff via magic sysrq

add support for GPE fields to be in any address space, not just IO.

This chunk is present in 2.4, missing in 2.5.  It
stops the loop thread from waiting on its owm buffers.
