Subject: s390/fpu: Move GR_NUM / VX_NUM macros to separate header file
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=495bc70aa32258c630c4f521ceadf30753f2a00b;p=thirdparty%2Flinux.git

s390/fpu: Move GR_NUM / VX_NUM macros to separate header file

Move GR_NUM / VX_NUM macros to separate insn-common-asm.h header file
so they can be reused for non-fpu insn constructs.
