History
Christophe Leroy ba454f9c8e powerpc/kuap: Add a generic intermediate layer 
Make the following functions generic to all platforms.
- bad_kuap_fault()
- kuap_assert_locked()
- kuap_save_and_lock() (PPC32 only)
- kuap_kernel_restore()
- kuap_get_and_assert_locked()

And for all platforms except book3s/64
- allow_user_access()
- prevent_user_access()
- prevent_user_access_return()
- restore_user_access()

Prepend __ in front of the name of platform specific ones.

For now the generic just calls the platform specific, but
next patch will move redundant parts of specific functions
into the generic one.
