2009-03-05x86: pre-initialize boot_cpu_data.x86_phys_bits to avoid system_state testsJeremy Fitzhardinge2-6/+5
Impact: cleanup, micro-optimization Pre-initialize boot_cpu_data.x86_phys_bits to a reasonable default to remove the use of system_state tests in __virt_addr_valid() and __phys_addr(). Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-03-05x86-32: use specific __vmalloc_start_set flag in __virt_addr_validJeremy Fitzhardinge3-4/+12
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.

2009-03-05x86: fix up some bad global variable names in mm/init.cPekka Enberg3-25/+25

2009-03-04x86, math-emu: fix init_fpu for task != currentDaniel Glöckner3-13/+28
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.

2009-03-04x86: set_highmem_pages_init() cleanup, #2Pekka Enberg1-9/+0
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.

2009-03-04x86: fix DMI on EFIBrian Maly1-2/+3
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).
