2009-02-23x86: remove various unused subarch hooksIngo Molnar
Impact: remove dead code Remove: - pre_setup_arch_hook() - mca_nmi_hook() If needed they can be added back via an x86_quirk handler. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-23x86: remove the Voyager 32-bit subarchIngo Molnar
Impact: remove unused/broken code The Voyager subarch last built successfully on the v2.6.26 kernel and has been stale since then and does not build on the v2.6.27, v2.6.28 and v2.6.29-rc5 kernels. No actual users beyond the maintainer reported this breakage. Patches were sent and most of the fixes were accepted but the discussion around how to do a few remaining issues cleanly fizzled out with no resolution and the code remained broken. In the v2.6.30 x86 tree development cycle 32-bit subarch support has been reworked and removed - and the Voyager code, beyond the build problems already known, needs serious and significant changes and probably a rewrite to support it. CONFIG_X86_VOYAGER has been marked BROKEN then. The maintainer has been notified but no patches have been sent so far to fix it. While all other subarchs have been converted to the new scheme, voyager is still broken. We'd prefer to receive patches which clean up the current situation in a constructive way, but even in case of removal there is no obstacle to add that support back after the issues have been sorted out in a mutually acceptable fashion. So remove this inactive code for now. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-02-22x86: Add IRQF_TIMER to legacy x86 timer interrupt descriptorsLinus Torvalds
Right now nobody cares, but the suspend/resume code will eventually want to suspend device interrupts without suspending the timer, and will depend on this flag to know. The modern x86 timer infrastructure uses the local APIC timers and never shows up as a device interrupt at all, so it isn't affected and doesn't need any of this. Cc: Rafael J.

If BIOS hands over the control to OS in legacy xapic mode, select legacy xapic related ops in the early apic probe and shift to x2apic ops later in the boot sequence, only after enabling x2apic mode. If BIOS hands over the control in x2apic mode, select x2apic related ops in the early apic probe.

2009-02-21x86_64: Fix S3 fail pathJiri Slaby
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.

2009-02-21x86, mm: fault.c, give another attempt at prefetch handing before SIGBUSIngo Molnar
Impact: extend prefetch handling on 64-bit Currently there's an extra is_prefetch() check done in do_sigbus(), which we only do on 32 bits. This is a last-ditch check before we terminate a task, so it's worth giving prefetch instructions another chance - should none of our existing quirks have caught a prefetch instruction related spurious fault. The only risk is if a prefetch causes a real sigbus, in that case we'll not OOM but try another fault. But this code has been on 32-bit for a long time, so it should be fine in practice. So do this on 64-bit too - and thus remove one more #ifdef. Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

Impact: cleanup Rename TASK_SIZE64 to TASK_SIZE_MAX, and provide the define on 32-bit too. (mapped to TASK_SIZE) This allows 32-bit code to make use of the (former-) TASK_SIZE64 symbol as well, in a clean way.

2009-02-21x86, mm: fault.c, remove #ifdef from do_page_fault()Ingo Molnar

Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-21x86, mm: fault.c, unify oops handlingIngo Molnar
Impact: add oops-recursion check to 32-bit Unify the oops state-machine, to the 64-bit version. It is slightly more careful in that it does a recursion check in oops_begin(), and is thus more likely to show the relevant oops. It also means that 32-bit will print one more line at the end of pagefault triggered oopses: printk(KERN_EMERG "CR2: %016lx\n", address); Which is generally good information to be seen in partial-dump digital-camera jpegs ;-) The downside is the somewhat more complex critical path. Both variants have been tested well meanwhile by kernel developers crashing their boxes so i dont think this is a practical worry. This removes 3 ugly #ifdefs from no_context() and makes the function a lot nicer read. Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-21x86, mm: fault.c, unify oops printingIngo Molnar
Impact: refine/extend page fault related oops printing on 64-bit - honor the pause_on_oops logic on 64-bit too - print out NX fault warnings on 64-bit as well - factor out the NX fault message to make it git-greppable and readable Note that this means that we do the PF_INSTR check on 32-bit non-PAE as well where it should not occur ... normally. Cannot hurt. Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-21x86, mm: fault.c, reorder functionsIngo Molnar
Impact: cleanup Avoid a couple more #ifdefs by moving fundamentally non-unifiable functions into a single #ifdef 32-bit / #else / #endif block in fault.c: vmalloc*(), dump_pagetable(), check_vm8086_mode().

2009-02-21x86, mm: fault.c, simplify kmmio_fault()Ingo Molnar
Impact: cleanup Remove an #ifdef from kmmio_fault() - we can do this by providing default implementations for is_kmmio_active() and kmmio_handler(). The compiler optimizes it all away in the !CONFIG_MMIOTRACE case. Also, while at it, clean up mmiotrace.h a bit: - standard header guards - standard vertical spaces for structure definitions No code changed (both with mmiotrace on and off in the config): text data bss dec hex filename 2947 12 12 2971 b9b fault.o.before 2947 12 12 2971 b9b fault.o.after Cc: Pekka Paalanen <pq@iki.fi> Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-21x86, mm: fault.c, enable PF_RSVD checks on 32-bit tooIngo Molnar
Impact: improve page fault handling robustness The 'PF_RSVD' flag (bit 3) of the page-fault error_code is a relatively recent addition to x86 CPUs, so the 32-bit do_fault() implementation never had it. This flag gets set when the CPU detects nonzero values in any reserved bits of the page directory entries. Extend the existing 64-bit check for PF_RSVD in do_page_fault() to 32-bit too. If we detect such a fault then we print a more informative oops and the pagetables. This unifies the code some more, removes an ugly #ifdef and improves the 32-bit page fault code robustness a bit. It slightly increases the 32-bit kernel text size. Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-21x86, mm: fault.c, factor out the vm86 fault checkIngo Molnar
Impact: cleanup Instead of an ugly, open-coded, #ifdef-ed vm86 related legacy check in do_page_fault(), put it into the check_v8086_mode() helper function and merge it with an existing #ifdef. Also, simplify the code flow a tiny bit in the helper. No code changed: arch/x86/mm/fault.o: text data bss dec hex filename 2711 12 12 2735 aaf fault.o.before 2711 12 12 2735 aaf fault.o.after Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-02-20x86, pat: add large-PAT check to split_large_page()Ingo Molnar
Impact: future-proof the split_large_page() function Linus noticed that split_large_page() is not safe wrt. the PAT bit: it is bit 12 on the 1GB and 2MB page table level (_PAGE_BIT_PAT_LARGE), and it is bit 7 on the 4K page table level (_PAGE_BIT_PAT). Currently it is not a problem because we never set _PAGE_BIT_PAT_LARGE on any of the large-page mappings - but should this happen in the future the split_large_page() would silently lift bit 12 into the lowlevel 4K pte and would start corrupting the physical page frame offset. Not fun. So add a debug warning, to make sure if something ever sets the PAT bit then this function gets updated too.

2009-02-20x86: check PMD in spurious_fault handlerSteven Rostedt
Impact: fix to prevent hard lockup on bad PMD permissions If the PMD does not have the correct permissions for a page access, but the PTE does, the spurious fault handler will mistake the fault as a lazy TLB transaction. This will result in an infinite loop of: fault -> spurious_fault check (pass) -> return to code -> fault This patch adds a check and a warn on if the PTE passes the permissions but the PMD does not.

2009-02-20x86: use the right protections for split-up pagetablesIngo Molnar
Steven Rostedt found a bug in where in his modified kernel ftrace was unable to modify the kernel text, due to the PMD itself having been marked read-only as well in split_large_page(). The fix, suggested by Linus, is to not try to 'clone' the reference protection of a huge-page, but to use the standard (and permissive) page protection bits of KERNPG_TABLE. The 'cloning' makes sense for the ptes but it's a confused and incorrect concept at the page table level - because the pagetable entry is a set of all ptes and hence cannot 'clone' any single protection attribute - the ptes can be any mixture of protections. With the permissive KERNPG_TABLE, even if the pte protections get changed after this point (due to ftrace doing code-patching or other similar activities like kprobes), the resulting combined protections will still be correct and the pte's restrictive (or permissive) protections will control it. Also update the comment. This bug was there for a long time but has not caused visible problems before as it needs a rather large read-only area to trigger. Steve possibly hacked his kernel with some really large arrays or so. Anyway, the bug is definitely worth fixing. [ Huang Ying also experienced problems in this area when writing the EFI code, but the real bug in split_large_page() was not realized back then. ] Reported-by: Steven Rostedt <rostedt@goodmis.org> Reported-by: Huang Ying <ying.huang@intel.com> Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
