Subject: x86/asm: Fix SETZ size enqcmds() build failure
Git-commit: d81ff5fe14a950f53e2833cfa196e7bb3fd5d4e3
Patch-mainline: v5.15-rc3
References: bsc#1178134
When building under GCC 4.9 and 5.5:
arch/x86/include/asm/special_insns.h: Assembler messages:
arch/x86/include/asm/special_insns.h:286: Error: operand size mismatch for `setz'
Change the type to "bool" for condition code arguments, as documented.
Fixes: 7f5933f81bd8 ("x86/asm: Add an enqcmds() wrapper for the ENQCMDS instruction")
