The patch below implements an algorithm to determine an unique GSI override
for mapping GSIs to IO-APIC pins correctly.  GSI overrides are required in
order for ES7000 machines to function properly since IRQ to pin mappings
are NOT all one-to-one.  This patch applies only to the Unisys specific
ES7000 machines and has been tested thoroughly on several models of the
ES7000 line.

In sched_exec, schedstat_inc will dereference a null pointer if no domain
is found with the SD_BALANCE_EXEC flag set.  This was exposed during
testing of the previous patches where cpus are temporarily attached to a
dummy domain without SD_BALANCE_EXEC set.

Add kapmd thread to provide a process context to handle "APM"
events submitted via apm_queue_event().

Add apm_queue_event(), which can be called from hardware
interrupt handlers and the like, typically to fire off a
suspend.

Move existing APM state definitions into struct apm_power_info,
and add further definitions describing other fields.

Ensure threads waiting for suspend to occur in apm_ioctl are
not woken by the pm_suspend thread freezing - they're already
frozen.

The original version had issues when two suspend events came
in at around the same time, causing APM to get confused:
threads became stuck in APM_IOC_SUSPEND and suspends_pending
incremented on each apm --suspend call.

Now, we only add a suspend event to a users queue and increment
suspends_pending if the user isn't already in the middle of
handling a suspend event.

Convert user_list_lock spinlock to a read/write semaphore;
the spinlock was affording us very little protection.

It seems that most architectures already include linux/device.h in their
own asm/dma-mapping.h.  Most but not all, and some drivers fail to
compile on those architectures that don't.  Since everybody needs it
let's include device.h from one place only and fix compilation for
everybody.

There's a double-free in the isofs filesystem.

Invalidate this pointer so it doesn't get freed twice.

The follow patch special cases the NR_CPUS <= BITS_PER_COMPAT_LONG case.
Without this patch, a 32bit task would be required to have a 64bit
cpumask no matter what value of NR_CPUS are used.

With this patch a compat long sized bitmask is allowed if NR_CPUS is
small enough to fit within it.

Of course applications should be using the glibc wrappers that use an
opaque cpu_mask_t type, but there could be older applications using the
syscalls directly.

Remove the set_fs hack in the compat affinity calls. Create
sched_getaffinity and sched_setaffinity helper functions that both the
native and compat affinity syscalls use.

Also make the compat functions match what the native ones are doing now,
setaffinity calls succeed no matter what length the bitmask is, but
getaffinity calls must pass in bitmasks at least as long as the kernel
type.

Thanks to David for his help in tracking it down.

  compile the kernel with sibling call optimization
  turned off. There is a problem with all functions
  using the optimization and the asmlinkage attribute.
  The compiler should not perform the optimization on
  these functions because it cannot preserve the syscall
  parameters in the callee. This caused SIGSEGV on programs
  traced with PTRACE_SYSCALL, for instance.

This patch kills the bogus radeonfb_read/write routines. In order to do so,
it adds a new member to fb_info, along with screen_base, which is screen_size,
indicating the mapped area. The default fb_read/write will now use that instead
of fix->smem_len if it is non-0, and radeonfb now sets it to the mapped size
of the framebuffer.
