[PATCH] Simplify smp_call_function*() by using common implementation
smp_call_function and smp_call_function_single are almost complete
duplicates of the same logic. This patch combines them by
implementing them in terms of the more general
smp_call_function_mask().
[ Jan, Andi: This only changes arch/i386; can x86_64 be changed in the
same way? ]

[PATCH] linux/x86: Use cpu_relax() rather than barrier() in smp_call_function()
Short of getting an explanation for the odd difference to native, make
the code match native (and also, in the case of x86-64,
__smp_call_function_single()).
As usual, written and tested against 2.6.24-rc3 and made apply against
2.6.18 without further testing.

try_to_free_pages does an smp_call_function to collect all the
partial discarded page lists and frees them.
There are two reasons why this is desirable. First, discarded page are
really cold. Before the guest can reaccess the page frame the host
