Subject: [PATCH 0/2] arm64: pointer auth cleanup
Date: Wed, 25 Jan 2023 18:21:59 +0000 [thread overview]
Message-ID: <20230125182201.800076-1-mark.rutland@arm.com> (raw)
With the recent dynamic SCS patches conditionally disabling pointer
authentication for leaf functions, I thought I'd try to clean things up
and consistently do so.
Patch 1 is (hopefully not controversial) Makefile cleanup.
Patch 2 disables pointer authentication for leaf functions, for the
reasons laid out in the commit message (which laregly boils down to
"it's not necessary" and "our prior rationale for doing so doesn't hold
water").
Thanks,
Mark.
