Impact: cleanup In preparation for moving the function declaration to a header file, unify 32-bit and 64-bit signatures. Signed-off-by:

Impact: cleanup The table_start, table_end, and table_top are too generic for global namespace so rename them to be more specific. Signed-off-by:

Impact: cleanup This patch moves the init_memory_mapping() function to common mm/init.c. Signed-off-by:

Impact: cleanup This patch adds an empty static inline init_gbpages() for the 32-bit version of init_memory_mapping() making both versions identical. Signed-off-by:

Impact: cleanup As a trivial preparation for moving common code to arc/x86/mm/init.c, ifdef the 32-bit and 64-bit versions of NR_RANGE_MR. Signed-off-by:

Impact: cleanup To reduce the diff between the 32-bit and 64-bit versions of init_memory_mapping(), ifdef configuration specific pfn setup code in the function. Signed-off-by:

Impact: cleanup This patch adds a sanity check to the 32-bit version of init_memory_mapping() to reduce the diff to the 64-bit version. Signed-off-by:
-
Pekka Enberg authored
Impact: cleanup The 64-bit version of init_memory_mapping() uses the last mapped address returned from kernel_physical_mapping_init() whereas the 32-bit version doesn't. This patch adds relevant ifdefs to both versions of the function to reduce the diff between them. Signed-off-by:

Impact: cleanup This patch renames after_init_bootmem to after_bootmem in mm/init_32.c to reduce the diff to the 64-bit version of of init_memory_mapping(). Signed-off-by:
-
Pekka Enberg authored
Impact: cleanup The save_mr() function already checks that start_pfn is less than end_pfn so we can remove the unnecessary check which reduces the diff between the 32-bit and the 64-bit versions of init_memory_mapping(). Signed-off-by:
-

Impact: cleanup Enabling NX, PSE, and PGE are only required on 32-bit so ifdef them in both versions of the function. Signed-off-by:
-
Pekka Enberg authored
Impact: cleanup This patch moves pgd_base out of init_memory_mapping() to reduce the diff between the 32-bit version and the 64-bit version of the function. Signed-off-by:
-
Pekka Enberg authored
Impact: cleanup There are some minor differences between the 32-bit and 64-bit find_early_table_space() functions. This patch wraps those differences under CONFIG_X86_32 to make the function identical on both configurations. Signed-off-by:
-
Pekka Enberg authored
Impact: cleanup To reduce the diff between the 32-bit and 64-bit versions of init_memory_mapping(), add gbpages support to the 32-bit version. Signed-off-by:

Impact: Fix boot failure on EFI system with large runtime memory range Brian Maly reported that some EFI system with large runtime memory range can not boot. Because the FIX_MAP used to map runtime memory range is smaller than run time memory range. This patch fixes this issue by re-implement efi_ioremap() with init_memory_mapping().

Impact: cleanup The zones are set up at this stage so there's a highmem zone available even for the UMA case. The only difference there is that for machines that have CONFIG_HIGHMEM enabled but don't have any highmem available, ->zone_start_pfn is zero whereas highstart_pfn is non-zero). The field is left zeroed because of the !size test in free_area_init_core() but shouldn't be a problem because add_highpages_with_active_regions() handles empty ranges just fine. Signed-off-by:

Impact: reactivate DMI quirks on EFI hardware DMI tables are loaded by EFI, so the dmi calls must happen after efi_init() and not before. Currently Apple hardware uses DMI to determine the framebuffer mappings for efifb. Without DMI working you also have no video on MacBook Pro. This patch resolves the DMI issue for EFI hardware (DMI is now properly detected at boot), and additionally efifb now loads on Apple hardware (i.e. video works). Signed-off-by:
