Dan Li 93cb263d81 arm64: Mark __stack_chk_guard as __ro_after_init 
[ Upstream commit 9fcb2e93f4 ]

__stack_chk_guard is setup once while init stage and never changed
after that.

Although the modification of this variable at runtime will usually
cause the kernel to crash (so does the attacker), it should be marked
as __ro_after_init, and it should not affect performance if it is
placed in the ro_after_init section.
