That document was wrong on some things, misleading on others; this
fixes some of the issues I noticed.

However it probably needs to say that drivers for devices that implement
the PCI PM spec "should" always use pci_set_power_state() to reduce the
power usage.  If I get ambitions I might submit a patch to the PCI core
to print a nag message for drivers that don't do that.


Updates the PCI PM docs, better matching the specs and code.

  - List both D3 states (D3hot, D3cold) up front.

  - Clarify that suspend() methods should disable I/0 (including DMA)
    and IRQs; it's not optional.

  - More accurately describe resume(); there are common cases where
    device re-initialization isn't appropriate.  The previous text said
    re-init was always required; that's false.

x86-64 in_gate_vma would take a read lock on the VMA when the passed
address was inside the 32bit vsyscall page.

This would be called by get_user_pages, which already holds the mmap_sem.

Unfortunately some callers of get_user_pages hold the mmap_sem for writing,
which could in theory cause a deadlock.

I think it can currently not happen because the only users who hold it for
write before calling gup() are coredump and AIO in the ring setup, and both
should not ever access the vsyscall page. 

But not taking the semaphore is safer and avoid this here.

CONFIG_FRAME_POINTER has never worked on x86-64 because it never passed

This fixes profile_pc to work properly on x86-64 and not crash.

It does now a simple backtrace to the caller of the spin lock without
requiring a frame pointer for this.

Frame pointer support has been dropped because it never worked.

There is still a small race window, but the only way to avoid it would be
to rewrite kernel/spinlock.c in assembler again.  The race will account a
profile tick the the parent of the spinlock caller.
