Subject: [patch 079/118] arm64: kasan: simplify and inline MTE functions
Date: Thu, 25 Feb 2021 17:20:31 -0800
Message-ID: <20210226012031.L0q86-Dw-%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210225171452.713967e96554bb6a53e44a19@linux-foundation.org>

Subject: arm64: kasan: simplify and inline MTE functions

This change provides a simpler implementation of mte_get_mem_tag(),
mte_get_random_tag(), and mte_set_mem_tag_range().

Simplifications include removing system_supports_mte() checks as these
functions are onlye called from KASAN runtime that had already checked
system_supports_mte().  Besides that, size and address alignment checks
are removed from mte_set_mem_tag_range(), as KASAN now does those.

This change also moves these functions into the asm/mte-kasan.h header and
implements mte_set_mem_tag_range() via inline assembly to avoid
unnecessary functions calls.
