Matt Fleming 2a5eacca85 sh: Move page table allocation out of line
We also switched away from quicklists and instead moved to slab
caches. After benchmarking both implementations the difference is
negligible. The slab caches suit us better though because the size of a
pgd table is just 4 entries when we're using a 3-level page table layout
and quicklists always deal with pages.

# Special flags for fault_64.o. This puts restrictions on the number of
# caller-save registers that the compiler can target when building this file.
# This is required because the code is called from a context in entry.S where
# very few registers have been saved in the exception handler (for speed
# reasons).
# The caller save registers that have been saved and which can be used are
# r2,r3,r4,r5 : argument passing
# r15, r18 : SP and LINK
# tr0-4 : allow all caller-save TR's. The compiler seems to be able to make
# use of them, so it's probably beneficial to performance to save them
# and have them available for it.
#
# The resources not listed below are callee save, i.e. the compiler is free to
# use any of them and will spill them to the stack itself.
