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.

Changes the rwlock to a spinlock, and drops the use-count variable.
Operations are always bound by the mutex now, so the use-count is no more
needed. For the same reason, the rwlock can become a simple spinlock.

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 f64da958df.
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.

This displays the statistics specified in the updated IP-MIB RFC
(RFC4293) in /proc/net/netstat. The reason why these are not displayed
in /proc/net/snmp is that some existing utilities are developed under
the assumption which ipstat items in /proc/net/snmp is unchanged.
