Make __copy_*_user_inatomic really atomic to avoid "Sleeping function called in atomic context" warnings, especially from futex code. This is made by adding another kmap_atomic slot and making copy_*_user_skas use kmap_atomic; also copy_*_user() becomes atomic, but that's true and is not a problem for i386 (and we can always add might_sleep there as done elsewhere). For TT mode kmap is not used, so there's no need for this. I've had to use another slot since both KM_USER0 and KM_USER1 are used elsewhere and could cause conflicts. Till now we reused the kmap_atomic slot list from the subarch, but that's not needed as that list must contain the common ones (used by generic code) + the ones used in architecture specific code (and Uml till now used none); so I've taken the i386 one after comparing it with ones from other archs, and added KM_UML_USERCOPY.
