[PATCH] MIPS: lib: Remove '.hidden' for local symbols

[PATCH] MIPS: lib: Remove '.hidden' for local symbols

[Nathan Chancellor]

After a recent change in binutils that warns when local symbols have
non-default visibility [1], there are a couple instances when building
arch/mips:

  Assembler messages:
  {standard input}: Warning: local symbol `__memset' has non-default visibility
  Assembler messages:
  {standard input}: Warning: local symbol `__memcpy' has non-default visibility

Remove the '.hidden' directives for these symbols to clear up the
warnings, as they are pointless with a local symbol, which is by
definition hidden. This results in no changes to these symbols in nm's
output when assembled with various copies of binutils.

Closes: https://lore.kernel.org/20260509122517.GA1108596@ax162/

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
