2021-12-23	powerpc/code-patching: Replace patch_instruction() by ppc_inst_write() in ↵	Christophe Leroy	1	-40/+45
	selftests The purpose of selftests is to check that instructions are properly formed. Not to check that they properly run. For that test it uses normal memory, not special test memory. In preparation of a future patch enforcing patch_instruction() to be used only on valid text areas, implement a ppc_inst_write() instruction which is the complement of ppc_inst_read(). This new function writes the formated instruction in valid kernel memory and doesn't bother about icache.

2021-12-23	powerpc/code-patching: Move code patching selftests in its own file	Christophe Leroy	1	-0/+357
	Code patching selftests are half of code-patching.c. As they are guarded by CONFIG_CODE_PATCHING_SELFTESTS, they'd be better in their own file. Also add a missing __init for instr_is_branch_to_addr() Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/c0c30504f04eb546a48ff77127a8bccd12a3d809.1638446239.git.christophe.leroy@csgroup.eu
