define an own ARRAY_SIZE macro in boot.h, similar to the other private

    that the per_cpu variable is the correct access to the variable.

powerpc: Fix loss of vdso on fork on 32-bit

When we fork, init_new_context() improperly resets the vdso_base
of the new context to 0.  That means that the new process loses
access to the vdso for signal trampolines.

The initialization should be unnecessary anyway as the context
on a fresh mm should be 0 in the first place and binfmt_elf
will initialize that value for a newly loaded process.

[ARM] 5196/1: fix inline asm constraints for preload

With gcc 4.3 and later, a pointer that has already been dereferenced is
assumed not to be null since it should have caused a segmentation fault
otherwise, hence any subsequent test against NULL is optimized away.

Current inline asm constraint used in the implementation of prefetch()
makes gcc believe that the pointer is dereferenced even though the PLD
instruction does not load any data and does not cause a segmentation
fault on null pointers, which causes all sorts of interesting results
when reaching the end of a linked lists for example.

Let's use a better constraint to properly represent the actual usage of
the pointer value.

spp_getpage is called from __init (__init_extra_mapping) and
non __init (set_pte_vaddr_pud) functions, so it can't be __init.
Unfortunately it calls alloc_bootmem_pages which is __init,
