Merge branch 'work.regset' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull ptrace regset updates from Al Viro: "Internal regset API changes: - regularize copy_regset_{to,from}_user() callers - switch to saner calling conventions for ->get() - kill user_regset_copyout() The ->put() side of things will have to wait for the next cycle, unfortunately. The balance is about -1KLoC and replacements for ->get() instances are a lot saner" * 'work.regset' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (41 commits) regset: kill user_regset_copyout{,_zero}() regset(): kill ->get_size() regset: kill ->get() csky: switch to ->regset_get() xtensa: switch to ->regset_get() parisc: switch to ->regset_get() nds32: switch to ->regset_get() nios2: switch to ->regset_get() hexagon: switch to ->regset_get() h8300: switch to ->regset_get() openrisc: switch to ->regset_get() riscv: switch to ->regset_get() c6x: switch to ->regset_get() ia64: switch to ->regset_get() arc: switch to ->regset_get() arm: switch to ->regset_get() sh: convert to ->regset_get() arm64: switch to ->regset_get() mips: switch to ->regset_get() sparc: switch to ->regset_get() ...
