Subject: [GIT PULL] arm64: Fixes for -rc3
Date: Wed, 9 Oct 2019 14:30:54 +0100 [thread overview]
Message-ID: <20191009133053.p7bxzkub32x3mclb@willie-the-truck> (raw)
Hi Linus,
Here is a larger-than-usual batch of arm64 fixes for -rc3. The bulk of
the fixes are dealing with a bunch of issues with the build system from
the compat vDSO, which unfortunately led to some significant Makefile
rework to manage the horrible combinations of toolchains that we can end
up needing to drive simultaneously. We came close to disabling the thing
entirely, but Vincenzo was quick to spin up some patches and I ended up
picking up most of the bits that were left. Future work will look at
disentangling the header files properly.
My subsequent vDSO fixes were:
Reviewed-by: Vincenzo Frascino <vincenzo.frascino@arm.com>
Tested-by: Vincenzo Frascino <vincenzo.frascino@arm.com>
but they were already in linux-next by then and I didn't want to rebase,
so hopefully you can just include those in the merge commit.
Other than that, we have some important fixes all over, including one
papering over the miscompilation fallout from forcing
CONFIG_OPTIMIZE_INLINING=y, which I'm still unhappy about. Harumph.
We've still got a couple of open issues, so I'm expecting to have some
more fixes later this cycle.
Thanks, and please pull.
Will
