Hi Simon,
you combined two patches from upstream as one single revert in [1].
What you have is [2]...
commit be6cb02779ca74d83481f017db21578cfe92891c
"x86: Align jump targets to 1-byte boundaries"
...combined with [3]...
commit/?id=52648e83c9a6b9f7fc3dd272d4d10175e93aa62a
"x86: Pack loops tightly as well"
So, can you do a proper single revert or two revert-patches?
Personally, I would keep the ifneq-line like in workaround_align_jump.patch.
9 +ifneq ($(COMPILER),clang)
10 # Align jump targets to 1 byte, not the default 16 bytes:
11 KBUILD_CFLAGS += -falign-jumps=1
12 -
13 # Pack loops tightly as well:
14 KBUILD_CFLAGS += -falign-loops=1
15 +endif
Have you a working aka bootable x86_64 setup Linux v4.2 or v4.2+?
Thanks in advance.
Regards,

P.S.: BTW, can you fix your Git From-line (UTF-x) in your generated
patches, Thanks.
