This reverts commit b6d1c9a4.

Others tell me that this address has worked for them, so I can only
assume that I hit a glitch in the sourceforge mail system.

m68k: implement __clear_user(), which is needed by fs/signalfd.c

Since we always let the MMU do all checking, clear_user() and __clear_user()
are identical. The old clear_user() is renamed to __clear_user() for
consistency.

"Remove hardcoding of hard_smp_processor_id on UP systems",
2f4dfe20 in Linus' tree, moved
the definition of hard_smp_processor_id linux/smp.h to asm/smp.h
for UP systems. This causes a regression on Alpha.

cc1: warnings being treated as errors
arch/alpha/kernel/setup.c: In function 'setup_arch':
arch/alpha/kernel/setup.c:506: warning: implicit declaration of function 'hard_smp_processor_id'
make[1]: *** [arch/alpha/kernel/setup.o] error 1
make: *** [arch/alpha/kernel] error 2

By including asm/smp.h non-conditionally in asm/mmu_context.h
the problem appears to be resolved.

lib/ioremap.c is presently only built in if CONFIG_MMU is set.  While this
is reasonable, platforms that support both CONFIG_MMU=y or n need to be
able to call in to this regardless.

As none of the current nommu platforms do anything special with ioremap(),
we assume that it's always successful.

This fixes the SH-4 build with CONFIG_MMU=n.

Fixes the epoll single pass code.  During the unlocked event delivery (to
userspace) code, the poll callback can re-issue new events, and we must
receive them correctly.  Since we loop in a lockless fashion, we want to be
O(nready), and we don't want to flash on/off the spinlock for every event, we
have the poll callback to use a secondary list to queue events while we're
inside the event delivery loop.  The rw_semaphore has been turned into a
mutex.  This patch also adds the wait-exclusive flag, as suggested by Davi
Arnaut.

This reverts commit f64da958.

Andi Kleen is unhappy with the changes, and they really do not seem
worth it.  IPMI could use DIE_NMI_IPI instead of the new callback, even
though that ends up having its own set of problems too, mainly because
the IPMI code cannot really know the NMI was from IPMI or not.

Manually fix up conflicts in arch/x86_64/kernel/traps.c and
drivers/char/ipmi/ipmi_watchdog.c.

The function xfrm_policy_byid takes a dir argument but finds the policy
using the index instead.  We only use the dir argument to update the
policy count for that direction.  Since the user can supply any value
for dir, this can corrupt our policy count.

I know this is the problem because a few days ago I was deleting
policies by hand using indicies and accidentally typed in the wrong
direction.  It still deleted the policy and at the time I thought
that was cool.  In retrospect it isn't such a good idea :)

I decided against letting it delete the policy anyway just in case
we ever remove the connection between indicies and direction.
