[uml-devel] [PATCH 2/6] uml: fix "reuse i386 cpu optimizations"

["Paolo 'Blaisorblade' Giarrusso" <blaisorblade@yahoo.it>]

From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

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.
