Add a bool parameter 'allow_block_mappings' to create_pgd_mapping() and the various helper functions that it descends into, to give the caller control over whether block entries may be used to create the mapping. The UEFI runtime mapping routines will use this to avoid creating block entries that would need to split up into page entries when applying the permissions listed in the Memory Attributes firmware table. This also replaces the block_mappings_allowed() helper function that was added for DEBUG_PAGEALLOC functionality, but the resulting code is functionally equivalent (given that debug_page_alloc does not operate on EFI page table entries anyway) Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> |
