um: reinstate kernel version in generated .config Commit 0954828fcbf3 ("kconfig: replace KERNELVERSION usage by the mainmenu's prompt") made the kernel version disappear from the generated .config file when configuring for UML. As UML's Kconfig doesn't have a mainmenu, kconfig falls back to the default string "Linux Kernel Configuration". Add a suitable mainmenu to the main UML Kconfig file to fix this.

[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).

um: disable CONFIG_CMPXCHG_LOCAL Commit 8a5ec0ba "Lockless (and preemptless) fastpaths for slub" makes use of this_cpu_cmpxchg_double() which needs this_cpu_cmpxchg16b_emu() on x86_64. Implementing cmpxchg16b emulation for UML would introduce too much complexity. So just disable it.

[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.
