[PATCH] uml: fixups for "reuse i386 cpu-specific tuning" A few fixups - show the new submenu only for x86 subarchitecture (it does not make sense to show it for x86_64 users) and remove X86_CMPXCHG, which is now a duplicate of Kconfig.i386, even though Kconfig doesn't complain (we also miss the dependency on !M386 CPU).

[PATCH] uml: support AES i586 crypto driver We want to make possible, for the user, to enable the i586 AES implementation. This requires a restructure. - Add a CONFIG_UML_X86 to notify that we are building a UML for i386. - Rename CONFIG_64_BIT to CONFIG_64BIT as is used for all other archs - Tell crypto/Kconfig that UML_X86 is as good as X86 - Tell it that it must exclude not X86_64 but 64BIT, which will give the same results. - Tell kbuild to descend down into arch/i386/crypto/ to build what's needed.

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.

[PATCH] unify x86/x86-64 semaphore code This patch moves the common code in x86 and x86-64's semaphore.c into a single file in lib/semaphore-sleepers.c. The arch specific asm stubs are left in the arch tree (in semaphore.c for i386 and in the asm for x86-64). There should be no changes in code/functionality with this patch.

[PATCH] Fix UML on non-standard VM split hosts This fixes UML on hosts with non-standard VM splits. We had changed the config variable that controls UML behavior on such hosts, but not propogated the change everywhere. In particular, the values of STUB_CODE and STUB_DATA relied on the old variable. I also reformatted the HOST_VMSPLIT_3G help to make it more standard. Spotted by uml@flonatel.org.

This is needed when the host kernel on which you run has a non-default
(like 2G/2G) memory split, instead of the customary 3G/1G. If you did
not recompile your own kernel but use the default distro's one, you can
safely accept the "Default split" option.

It can be enabled on recent (>=2.6.16-rc2) vanilla kernels via
CONFIG_VM_SPLIT_*, or on previous kernels with special patches (-ck
patchset by Con Kolivas, or other ones) - option names match closely the
host CONFIG_VM_SPLIT_* ones.

A lower setting (where 1G/3G is lowest and 3G/1G is higher) will
tolerate even more "normal" host kernels, but an higher setting will be
stricter.
