H A D | sleep.S | 82e49588 Wed Jan 11 04:22:31 CST 2023 Ard Biesheuvel <ardb@kernel.org> arm64: head: Move all finalise_el2 calls to after __enable_mmu
In the primary boot path, finalise_el2() is called much later than on the secondary boot or resume-from-suspend paths, and this does not appear to be intentional.
Since we aim to do as little as possible before enabling the MMU and caches, align secondary and resume with primary boot, and defer the call to after the MMU is turned on. This also removes the need to clean finalise_el2() to the PoC once we enable support for booting with the MMU on.
