This patch modifies the get_irqnr_preamble macro to work with multiple

This patch moves the platform specific definitions from platform.h into
the board-eb.h file. It drops the INT_* definitions as they are no
longer used in irqs.h (moved to board-eb.h). It renames REALVIEW_*
macros to REALVIEW_EB_* or REALVIEW_EB11MP_* to distinguish between
standard EB and EB + the ARM11MPCore tile. The platform.h file contains
common definitions to the RealView platforms and it is only directly
included in board-*.h files.

This patch adds dummy local timers for each CPU so that the board clock
device is used to broadcast events to the other CPUs. The patch also
adds the declaration for the dummy_timer_setup function (the equivalent
of local_timer_setup when CONFIG_LOCAL_TIMERS is not set).

Due to the way clockevents work, the dummy timer on the first CPU has to
be registered before the board timer.

Because hpet_rtc_interrupt()'s call to get_rtc_time() ends up
resolving to include/asm-generic/rtc.h's (hilariously inlined)
get_rtc_time(), which does spin_unlock_irq() from hard IRQ context.

Rather than unconditionally reloading cr3, only do so if the pud we're
updating is within the active pgd.

This eliminates TLB flushes most of the time.  The
performance-critical uses of pud_clear are during execve and exit, but
in those cases cr3 is referring to some other pagetable.  The only
other use of pud_clear is during a large (1Gbyte+) munmap, and those
are sufficiently rare that a couple of cr3 reloads won't hurt.

The volatile keyword was removed from the clflush() prototype
in commit e34907ae; the comment there
states:

    x86: remove volatile keyword from clflush.

    the p parameter is an explicit memory reference, and is
    enough to prevent gcc to being nasty here. The volatile
    seems completely not needed.

This reflects incorrect understanding of the function of the volatile
keyword there.  The purpose of the volatile keyword is informing gcc
that it is safe to pass a volatile pointer to this function.

Currently, the atags used by kexec are fixed to the ones originally used
to boot the kernel. This is less than ideal as changing the commandline,
initrd and other options would be a useful feature.

This patch exports the atags used for the current kernel to userspace
through an "atags" file in procfs. The presence of the file is
controlled by its own Kconfig option and cleans up several ifdef blocks
into a separate file. The tags for the new kernel are assumed to be at
a fixed location before the kernel image itself. The location of the
tags used to boot the original kernel is unimportant and no longer
saved.
