Subject: [PATCH] ARM: remove unnecessary __LINUX_ARM_ARCH__ check in <asm/cp15.h>
Date: Sun, 10 May 2026 15:50:12 -0700 [thread overview]
Message-ID: <20260510225015.15311-1-enelsonmoore@gmail.com> (raw)
__LINUX_ARM_ARCH__ is only defined to 3 on the Risc PC. This is because
its currently supported configuration uses a StrongARM ARMv4 CPU, but
its bus does not support half-word accesses, so LDRH/STRH instructions
are disabled for it. Otherwise, it is a standard ARMv4 platform.
Support for actual ARMv3 CPUs was dropped in commit 357c9c1f07d4 ("ARM:
Remove support for ARMv3 ARM610 and ARM710 CPUs"), and therefore the
check for __LINUX_ARM_ARCH__ in <asm/cp15.h> is unnecessary. Remove it.
