Hi Greg and Sasha,
Please consider applying the following patches to 6.4 and 6.3, they
should apply cleanly.
08f6554ff90e ("mips: Include KBUILD_CPPFLAGS in CHECKFLAGS invocation")
a7e5eb53bf9b ("powerpc/vdso: Include CLANG_FLAGS explicitly in ldflags-y")
cff6e7f50bd3 ("kbuild: Add CLANG_FLAGS to as-instr")
43fc0a99906e ("kbuild: Add KBUILD_CPPFLAGS to as-option invocation")
feb843a469fb ("kbuild: add $(CLANG_FLAGS) to KBUILD_CPPFLAGS")
They resolve and help avoid build breakage with tip of tree clang, which
has become a little stricter in the flags that it will accept for a
particular target, which requires '--target=' to be passed along to all
invocations of $(CC). Our continuous integration does not currently show
any breakage with 6.1 and earlier; should these patches be needed there,
I will send them at a later time.
Cheers,
Nathan
