* [PATCH] ptrace: Fix EFL_OFFSET value according to i386 pda changesJeremy Fitzhardinge2006-12-22
| | | | | | | | | | | | | | | | | | | The PDA patches introduced a bug in ptrace: it reads eflags from the wrong place on the target's stack, but writes it back to the correct place. The result is a corrupted eflags, which is most visible when it turns interrupts off unexpectedly. This patch fixes this by making the ptrace code a little less fragile. It changes [gs]et_stack_long to take a straightforward byte offset into struct pt_regs, rather than requiring all callers to do a sizeof(struct pt_regs) offset adjustment. This means that the eflag's offset (EFL_OFFSET) on the target stack can be simply computed with offsetof().

* [PATCH] compile error of register_memory()Yasunori Goto2006-12-22
| | | | | | | | | | | | | register_memory() becomes double definition in 2.6.20-rc1. It is defined in arch/i386/kernel/setup.c as static definition in 2.6.19. But it is moved to arch/i386/kernel/e820.c in 2.6.20-rc1. And same name function is defined in driver/base/memory.c too. So, it becomes cause of compile error of duplicate definition if memory hotplug option is on.

* PCI: Fix multiple problems with VIA hardwareAlan Cox2006-12-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is designed to fix: - Disk eating corruptor on KT7 after resume from RAM - VIA IRQ handling - VIA fixups for bus lockups after resume from RAM The core of this is to add a table of resume fixups run at resume time. We need to do this for a variety of boards and features, but particularly we need to do this to get various critical VIA fixups done on resume. The second part of the problem is to handle VIA IRQ number rules which are a bit odd and need special handling for PIC interrupts. Various patches broke various boxes and while this one may not be perfect (hopefully it is) it ensures the workaround is applied to the right devices only. From: Jean Delvare <khali@linux-fr.org> Now that PCI quirks are replayed on software resume, we can safely re-enable the Asus SMBus unhiding quirk even when software suspend support is enabled.

| * [PATCH] x86: Fix boot hang due to nmi watchdog init codeRavikiran G Thirumalai2006-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.19 stopped booting (or booted based on build/config) on our x86_64 systems due to a bug introduced in 2.6.19. check_nmi_watchdog schedules an IPI on all cpus to busy wait on a flag, but fails to set the busywait flag if NMI functionality is disabled. This causes the secondary cpus to spin in an endless loop, causing the kernel bootup to hang. Depending upon the build, the busywait flag got overwritten (stack variable) and caused the kernel to bootup on certain builds. Following patch fixes the bug by setting the busywait flag before returning from check_nmi_watchdog. I guess using a stack variable is not good here as the calling function could potentially return while the busy wait loop is still spinning on the flag.

They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

The main advantage in using the generic BUG machinery for i386 is that the inlined overhead of BUG is just the ud2a instruction; the file+line(+function) information are no longer inlined into the instruction stream.

| | * [PATCH] i386: touch softlockup during backtracingDave Jones2006-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes the soft watchdog fires after we're done oopsing. See http://projects.info-pull.com/mokb/MOKB-25-11-2006.html for an example. AK: changed to touch_nmi_watchdog() Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de>
| | * [PATCH] x86: add sysctl for kstack_depth_to_printChuck Ebbert2006-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add sysctl for kstack_depth_to_print. This lets users change the amount of raw stack data printed in dump_stack() without having to reboot. Signed-off-by: Chuck Ebbert <76306.1226@compuserve.com> Signed-off-by: Andi Kleen <ak@suse.de>
| | * [PATCH] i386: remove duplicate printkDave Jones2006-12-06
| | | | | | | | | | | | | | | | | | | | | | | | We do the exact same printk about a dozen lines above with no intermediate printk's. Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using memmap kernel parameter in EFI boot we should also add to memory map memory regions of runtime services to enable their mapping later.

| | * [PATCH] x86: Regard MSRs in lapic_suspend()/lapic_resume()Karsten Wiese2006-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Read/Write APIC_LVTPC and APIC_LVTTHMR only, if get_maxlvt() returns certain values. This is done like everywhere else in i386/kernel/apic.c, so I guess its correct. Suspends/Resumes to disk fine and eleminates an smp_error_interrupt() here on a K8.

| | * [PATCH] i386: Avoid boot warning with apic=debugAndi Kleen2006-12-06
| | | | | | | | | | | | | | | | | | | | | | | | There are two consumers of apic=: the apic debug level and the low level generic architecture code. early_param would warn when the low level code rejected "debug". Avoid this. Signed-off-by: Andi Kleen <ak@suse.de>
| | * [PATCH] i386: i386 add Intel BTS cpufeature bit and detection (take 2)Stephane Eranian2006-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is a small patch for i386 which adds a cpufeature flag and detection code for Intel's Branch Trace Store (BTS) feature. This feature can be found on Intel P4 and Core 2 processors among others. It can also be used by perfmon. changelog: - add CPU_FEATURE_BTS - add Branch Trace Store detection signed-off-by: stephane eranian <eranian@hpl.hp.com> Signed-off-by: Andi Kleen <ak@suse.de>

| | * [PATCH] x86: fix the irqbalance quirk for E7320/E7520/E7525Siddha, Suresh B2006-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the irqbalance quirks for E7320/E7520/E7525(Errata 23 in http://download.intel.com/design/chipsets/specupdt/30304203.pdf) to early quirks. And add a PCI quirk for these platforms to check(which happens very late during the boot) if the APIC routing is indeed set to default flat mode. This fixes the breakage(in x86_64) of this quirk due to cpu hotplug which selects physical mode instead of the logical flat(as needed for this errata workaround).
