Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

obj-$(CONFIG_HUGETLB_PAGE) += hugetlbpage.o
# Special flags for tlbmiss.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.
