2009-03-04x86: EFI: Back efi_ioremap with init_memory_mapping instead of FIX_MAPHuang Ying
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().

2009-03-04x86: fix DMI on EFIBrian Maly
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).

2009-03-02x86-64: syscall-audit: fix 32/64 syscall holeRoland McGrath
On x86-64, a 32-bit process (TIF_IA32) can switch to 64-bit mode with ljmp, and then use the "syscall" instruction to make a 64-bit system call. A 64-bit process make a 32-bit system call with int $0x80. In both these cases, audit_syscall_entry() will use the wrong system call number table and the wrong system call argument registers. This could be used to circumvent a syscall audit configuration that filters based on the syscall numbers or argument details.

2009-03-02x86: unify chunks of kernel/process*.cJeremy Fitzhardinge
With x86-32 and -64 using the same mechanism for managing the tss io permissions bitmap, large chunks of process*.c are trivially unifyable, including: - exit_thread - flush_thread - __switch_to_xtra (along with tsc enable/disable) and as bonus pickups: - sys_fork - sys_vfork (Note: asmlinkage expands to empty on x86-64) Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-03-02x86-32: use non-lazy io bitmap context switchingJeremy Fitzhardinge
Impact: remove 32-bit optimization to prepare unification x86-32 and -64 differ in the way they context-switch tasks with io permission bitmaps. x86-64 simply copies the next tasks io bitmap into place (if any) on context switch. x86-32 invalidates the bitmap on context switch, so that the next IO instruction will fault; at that point it installs the appropriate IO bitmap. This makes context switching IO-bitmap-using tasks a bit more less expensive, at the cost of making the next IO instruction slower due to the extra fault. This tradeoff only makes sense if IO-bitmap-using processes are relatively common, but they don't actually use IO instructions very often. However, in a typical desktop system, the only process likely to be using IO bitmaps is the X server, and nothing at all on a server. Therefore the lazy context switch doesn't really win all that much, and its just a gratuitious difference from 64-bit code. This patch removes the lazy context switch, with a view to unifying this code in a later change.

Impact: Cleanup Checkin be44d2aabce2d62f72d5751d1871b6212bf7a1c7 eliminates the use of a 16-bit stack for espfix. However, at least one instruction remained that only operated on the low 16 bits of %esp. This is not a bug per se because the kernel stack is always an aligned 4K or 8K block. Therefore it cannot cross 64K boundaries; this code, in fact, relies strictly on that fact. However, it's a lot cleaner (and, for that matter, smaller) to operate on the entire 32-bit register.

As acpi_enter_sleep_state can fail, take this into account in do_suspend_lowlevel and don't return to the do_suspend_lowlevel's caller. This would break (currently) fpu status and preempt count. Technically, this means use `call' instead of `jmp' and `jmp' to the `resume_point' after the `call' (i.e. if acpi_enter_sleep_state returns=fails). `resume_point' will handle the restore of fpu and preempt count gracefully.

Impact: Bug fix on UP Checkin 6ec68bff3c81e776a455f6aca95c8c5f1d630198: x86, mce: reinitialize per cpu features on resume introduced a call to mce_cpu_features() in the resume path, in order for the MCE machinery to get properly reinitialized after a resume. However, this function (and its successors) was flagged __cpuinit, which becomes __init on UP configurations (on SMP suspend/resume requires CPU hotplug and so this would not be seen.) Remove the offending __cpuinit annotations for mce_cpu_features() and its successor functions. Cc: Andi Kleen <ak@linux.intel.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: H.
