2005-10-30[PATCH] uml: fix "reuse i386 cpu optimizations"Paolo 'Blaisorblade' Giarrusso
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.

2005-09-05[PATCH] uml: mark SMP on UML/x86_64 as brokenJeff Dike
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.

2005-09-05[PATCH] uml: Rename Kconfig files to be like the other archesJeff Dike
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.
