Revert "arm64: Mark kernel page ranges contiguous"
This reverts commit 348a65cd . Incorrect page table manipulation that does not respect the ARM ARM recommended break-before-make sequence may lead to TLB conflicts. The contiguous PTE patch makes the system even more susceptible to such errors by changing the mapping from a single page to a contiguous range of pages. An additional TLB invalidation would reduce the risk window, however, the correct fix is to switch to a temporary swapper_pg_dir. Once the correct workaround is done, the reverted commit will be re-applied. Signed-off-by:Catalin Marinas <catalin.marinas@arm.com> Reported-by:
