Subject: [PATCH] ARM: remove unnecessary __LINUX_ARM_ARCH__ check in <asm/cp15.h>

From: Ethan Nelson-Moore <[email-masked]>
Date: Sun, 10 May 2026 15:50:12 -0700

__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.
