	Use fixmaps for text patching when the kernel text is read-only, inspired by x86. This makes jump labels and kprobes work with the currently available CONFIG_DEBUG_SET_MODULE_RONX and the upcoming CONFIG_DEBUG_RODATA options. Signed-off-by: Rabin Vincent <rabin@rab.in> [kees: fixed up for merge with "arm: use generic fixmap.h"] [kees: added parse acquire/release annotations to pass C=1 builds] [kees: always use stop_machine to keep TLB flushing local] Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Nicolas Pitre <nico@linaro.org>
2012-03-24	ARM: 7332/1: extract out code patch function from kprobes	Rabin Vincent
	Extract out the code patching code from kprobes so that it can be used from the jump label code. Additionally, the separated code: - Uses the IS_ENABLED() macros instead of the #ifdefs for THUMB2 support - Unifies the two separate functions in kprobes, providing one function that uses stop_machine() internally, and one that can be called from stop_machine() directly - Patches the text on all CPUs only on processors requiring software broadcasting of cache operations Acked-by: Jon Medhurst <tixy@yxit.co.uk> Tested-by: Jon Medhurst <tixy@yxit.co.uk> Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
