in v4.4.y.queue (v4.4.179-143-gc4db218e9451).
This is due to commit 9b2d4e06d7f1 ("powerpc/64s: Add support for a store
forwarding barrier at kernel entry/exit"), which is part of a large patch
series and can not easily be reverted.
Guess I'll stop doing ppc:allmodconfig builds in v4.4.y ?
Michael, I thought this patch series was supposed to fix ppc issues, not
add to them :)
Any ideas on what to do here?
What exact code do you build?
$ make ARCH=powerpc CROSS_COMPILE=powerpc64-linux- allmodconfig
$ powerpc64-linux-gcc --version
powerpc64-linux-gcc (GCC) 8.3.0
Gcc should not see this file. I am asking because I do not see an .org
directive at line 839 of 4.4.179. I probably need some different repo
or extra patches to see the same code as you do.
v4.4.179-143-gc4db218e9451 from
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git
branch linux-4.4.y
That also includes 'powerpc/64s: Improve RFI L1-D cache flush fallback',
but reverting it does not make a difference. Also, the .org is
hidden in STD_RELON_EXCEPTION_PSERIES().
