b365157be3 [PATCH] uml: fix "reuse i386 cpu optimizations"
Remove RWSEM_GENERIC_SPINLOCK, it's now defined (only if needed) by the
underlying arch/i386/Kconfig.cpu.  Leave it only for x86_64.  Even there, it's
totally wrong, as they even have the code to support XCHG_ADD.

02edeb586a [PATCH] uml: mark SMP on UML/x86_64 as broken
Noticed by Al Viro <viro@parcelfarce.linux.theplanet.co.uk> - SMP on x86_64 is
fundamentally broken due to UML's reuse of the host arch's percpu stuff.  This
is OK on x86, but the x86_64 pda stuff just won't work for UML.

08b178ebf3 [PATCH] uml: Rename Kconfig files to be like the other arches
To the extent that sub-Kconfig files exist elsewhere in the tree, they are
named Kconfig.foo, rather than the Kconfig_foo that UML has.  This patch
brings the names in line with the rest of the tree.
