With CONFIG_DEBUG_VM, an assertion is made when changing the protection flags of a PTE that the PTE is locked. Huge pages use a different pagetable format and the assertion is bogus and will always trigger with a bug looking something like Unable to handle kernel paging request for data at address 0xf1a00235800006f8 Faulting instruction address: 0xc000000000034a80 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=32 NUMA Maple Modules linked in: dm_snapshot dm_mirror dm_region_hash dm_log dm_mod loop evdev ext3 jbd mbcache sg sd_mod ide_pci_generic pata_amd ata_generic ipr libata tg3 libphy scsi_mod windfarm_pid windfarm_smu_sat windfarm_max6690_sensor windfarm_lm75_sensor windfarm_cpufreq_clamp windfarm_core i2c_powermac NIP: c000000000034a80 LR: c000000000034b18 CTR: 0000000000000003 REGS: c000000003037600 TRAP: 0300 Not tainted (2.6.30-rc3-autokern1) MSR: 9000000000009032 <EE,ME,IR,DR> CR: 28002484 XER: 200fffff DAR: f1a00235800006f8, DSISR: 0000000040010000 TASK = c0000002e54cc740[2960] 'map_high_trunca' THREAD: c000000003034000 CPU: 2 GPR00: 4000000000000000 c000000003037880 c000000000895d30 c0000002e5a2e500 GPR04: 00000000a0000000 c0000002edc40880 0000005700000393 0000000000000001 GPR08: f000000011ac0000 01a00235800006e8 00000000000000f5 f1a00235800006e8 GPR12: 0000000028000484 c0000000008dd780 0000000000001000 0000000000000000 GPR16: fffffffffffff000 0000000000000000 00000000a0000000 c000000003037a20 GPR20: c0000002e5f4ece8 0000000000001000 c0000002edc40880 0000000000000000 GPR24: c0000002e5f4ece8 0000000000000000 00000000a0000000 c0000002e5f4ece8 GPR28: 0000005700000393 c0000002e5a2e500 00000000a0000000 c000000003037880 NIP [c000000000034a80] .assert_pte_locked+0xa4/0xd0 LR [c000000000034b18] .ptep_set_access_flags+0x6c/0xb4 Call Trace: [c000000003037880] [c000000003037990] 0xc000000003037990 (unreliable) [c000000003037910] [c000000000034b18] .ptep_set_access_flags+0x6c/0xb4 [c0000000030379b0] [c00000000014bef8] .hugetlb_cow+0x124/0x674 [c000000003037b00] [c00000000014c930] .hugetlb_fault+0x4e8/0x6f8 [c000000003037c00] [c00000000013443c] .handle_mm_fault+0xac/0x828 [c000000003037cf0] [c0000000000340a8] .do_page_fault+0x39c/0x584 [c000000003037e30] [c0000000000057b0] handle_page_fault+0x20/0x5c Instruction dump: 7d29582a 7d200074 7800d182 0b000000 3c004000 3960ffff 780007c6 796b00c4 7d290214 7929a302 1d290068 7d6b4a14 <800b0010> 7c000074 7800d182 0b000000 This patch fixes the problem by not asseting the PTE is locked for VMAs backed by huge pages.

Ian Campbell noticed that since "Eliminate thousands of warnings with gcc 3.2 build" (commit 57adc4d2) all WARN_ON()'s currently appear to come from warn_slowpath_null(), eg: WARNING: at kernel/softirq.c:143 warn_slowpath_null+0x1c/0x20() because now that warn_slowpath_null() is in the call path, the __builtin_return_address(0) returns that, rather than the place that caused the warning. Fix this by splitting up the warn_slowpath_null/fmt cases differently, using a common helper function, and getting the return address in the right place. This also happens to avoid the unnecessary stack usage for the non-stdargs case, and just generally cleans things up. Make the function name printout use %pS while at it.

Processor idle power states C2 and C3 stop the TSC on many machines. Linux recognizes this situation and marks the TSC as unstable: Marking TSC unstable due to TSC halts in idle But if those same machines are booted with "processor.max_cstate=1", then there is no need to validate C2 and C3, and no need to disable the TSC, which can be reliably used as a clocksource.

This patch provides new heuristics for parsing both the form factor and media rotation rate ATA IDENFITY words. The reported ATA version must be 7 or greater and the device must return values defined as valid in the standard. Only then are the characteristics reported to SCSI via the VPD B1 page. This seems like a reasonable compromise to me considering that we have been shipping several kernel releases that key off the rotation rate bit without any version checking whatsoever.

devpts_get_sb() calls memset(0) to clear mount options and calls parse_mount_options() if user specified any mount options. The memset(0) is bogus since the 'mode' and 'ptmxmode' options are non-zero by default. parse_mount_options() restores options to default anyway and can properly deal with NULL mount options. So in devpts_get_sb() remove memset(0) and call parse_mount_options() even for NULL mount options. Bug reported by Eric Paris: http://lkml.org/lkml/2009/5/7/448.
