Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rw/uml
Pull UML updates from Richard Weinberger: "Most changes are bug fixes and cleanups" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rw/uml: um: missing checks of __put_user()/__get_user() return values um: stub_rt_sigsuspend isn't needed these days anymore um/x86: merge (and trim) 32- and 64-bit variants of ptrace.h irq: Remove irq_chip->release() um: Remove CONFIG_IRQ_RELEASE_METHOD um: Remove usage of irq_chip->release() um: Implement um_free_irq() um: Fix __swp_type() um: Implement a custom pte_same() function um: Add BUG() to do_ops()'s error path um: Remove unused variables um: bury unused _TIF_RESTORE_SIGMASK um: wrong sigmask saved in case of multiple sigframes um: add TIF_NOTIFY_RESUME um: ->restart_block.fn needs to be reset on sigreturn
