#     powerpc/lib: fix book3s/32 boot failure due to code patching
#     
#     Commit 51c3c62b58b3 ("powerpc: Avoid code patching freed init
#     sections") accesses 'init_mem_is_free' flag too early, before the
#     kernel is relocated. This provokes early boot failure (before the
#     console is active).
#     
#     As it is not necessary to do this verification that early, this
#     patch moves the test into patch_instruction() instead of
#     __patch_instruction().
#     
#     This modification also has the advantage of avoiding unnecessary
#     remappings.
#     
#     Fixes: 51c3c62b58b3 ("powerpc: Avoid code patching freed init sections")
