Code patching on powerpc with a STRICT_KERNEL_RWX uses a userspace
address in a temporary mm on Radix now. Use __put_user() to avoid write
failures due to KUAP when attempting a "hijack" on the patching address.
__put_user() also works
Code patching on powerpc with a STRICT_KERNEL_RWX uses a userspace
address in a temporary mm on Radix now. Use __put_user() to avoid write
failures due to KUAP when attempting a "hijack" on the patching address.
__put_user() also works with the non-userspace, vmalloc-based patching
address on
