Jeremy Fitzhardinge authored
Rather than relying on the ever-unreliable system_state, add a specific __vmalloc_start_set flag to indicate whether the vmalloc area has meaningful boundaries yet, and use that in x86-32's __phys_addr and __virt_addr_valid. Signed-off-by:

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:

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 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:

Impact: fix math-emu related crash while using GDB/ptrace init_fpu() calls finit to initialize a task's xstate, while finit always works on the current task. If we use PTRACE_GETFPREGS on another process and both processes did not already use floating point, we get a null pointer exception in finit. This patch creates a new function finit_task that takes a task_struct parameter. finit becomes a wrapper that simply calls finit_task with current. On the plus side this avoids many calls to get_current which would each resolve to an inline assembler mov instruction. An empty finit_task has been added to i387.h to avoid linker errors in case the compiler still emits the call in init_fpu when CONFIG_MATH_EMULATION is not defined. The declaration of finit in i387.h has been removed as the remaining code using this function gets its prototype from fpu_proto.h. 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:
