So I did a comparison with a full allyesconfig between -rc2 and -rc2 +
v4. I find quite a lot binary differences, but not a single objdump -d
difference (object file by object file) just by fixing UTS_RELEASE to
the same value, so I guess that is a very good sign in case someone
wants to pick the entire series sooner than expected. Regardless, I
will send the separate __naked patches.
I should note that, at some point in one of my allyesconfig builds I got this:
UPD include/generated/compile.h
CC init/version.o
AR init/built-in.a
AR built-in.a
LD vmlinux.o
MODPOST vmlinux.o
ld: drivers/edac/amd64_edac.o(.text+0x200031d2): reloc against
`__asan_load4_noabort': error 4
ld: final link failed: Nonrepresentable section on output
Makefile:1035: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1
Running make (without cleaning) didn't reproduce it, and the other
allyesconfig builds didn't suffer any problem either. Maybe my
hardware is failing, but I wanted to let you know nevertheless.
Cheers,
Miguel
