From: Will Deacon <will@kernel.org> To: torvalds@linux-foundation.org Cc: catalin.marinas@arm.com, linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org 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.
