[PATCH 06/15] x86/headers: Unify register type definitions between 32-bit compat and i386

Show all headers | View raw

The following sigcontext related types were duplicated across native 32-bit and
compat 32-bit headers:

  struct _fpreg;
  struct _fpxreg;
  struct _xmmreg;

  X86_FXSR_MAGIC

Unify them.
