interfaces were poll(2) and select(2).  As each event monitor -
trigger - handling iteration took O(n) where `n' is the number of
watched fds, it makes sense to spread them to many pollers such that
the `n' can be divided by the number of pollers.  However, this
doesn't make any sense in kernel because persistent edge triggered
event monitoring is how the whole thing is implemented in the kernel
in the first place.

This patch converts trans_fd to use single poller which watches all
the fds instead of the poll of pollers approach.  All the fds are
registered for monitoring on creation and only the fds with pending
events are scanned when something happens much like how epoll is

x86 ACPI: Fix breakage of resume on 64-bit UP systems with SMP kernel

We are now using per CPU GDT tables in head_64.S and the original
early_gdt_descr.address is invalidated after boot by
setup_per_cpu_areas().  This breaks resume from suspend to RAM on
x86_64 UP systems using SMP kernels, because this part of head_64.S
is also executed during the resume and the invalid GDT address
causes the system to crash.  It doesn't break on 'true' SMP systems,
because early_gdt_descr.address is modified every time
native_cpu_up() runs.  However, during resume it should point to the
GDT of the boot CPU rather than to another CPU's GDT.

For this reason, during suspend to RAM always make
early_gdt_descr.address point to the boot CPU's GDT.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=11568, which
is a regression from 2.6.26.
