svn commit: r304096 - head/lib/libthr/arch/mips/include

[Adrian Chadd]

New Revision: 304096
URL: https://svnweb.freebsd.org/changeset/base/304096

Log:
  [mips] convert over =v to =r for the inline assembly.
  
  Later gcc and clang have deprecated =v (which maps to a specific temp
  register) and instead we should just use =r to have the assembler
  (hopefully!) save/restore things appropriately after choosing
  a register.
  
  Tested:
  
  * AR9344 SoC, with userreg support
  * AR9331 SoC, with no userreg support
