Subject: [PATCH 00/13] Make user_regset_copyin_ignore() *void*

Here are 13 patches against the 'next-20221014' tag of the 'linux-next.git'
repo.  I'm not sure how this cross-arch series should be merged -- perhaps
thru Andrew Morton's tree?

user_regset_copyin_ignore() apparently cannot fail and so always returns 0.
Let's first remove the result checks in several architectures that call this
function and then make user_regset_copyin_ignore() return *void* instead of
*int*...

Sergey Shtylyov (13):
  arc: ptrace: user_regset_copyin_ignore() always returns 0
  arm: ptrace: user_regset_copyin_ignore() always returns 0
  arm64: ptrace: user_regset_copyin_ignore() always returns 0
  hexagon: ptrace: user_regset_copyin_ignore() always returns 0
  ia64: ptrace: user_regset_copyin_ignore() always returns 0
  mips: ptrace: user_regset_copyin_ignore() always returns 0
  nios2: ptrace: user_regset_copyin_ignore() always returns 0
  openrisc: ptrace: user_regset_copyin_ignore() always returns 0
  parisc: ptrace: user_regset_copyin_ignore() always returns 0
  powerpc: ptrace: user_regset_copyin_ignore() always returns 0
  sh: ptrace: user_regset_copyin_ignore() always returns 0
  sparc: ptrace: user_regset_copyin_ignore() always returns 0
  regset: make user_regset_copyin_ignore() *void*
