2011-10-24MIPS: perf: Reorganize contents of perf support files.David Daney
The contents of arch/mips/kernel/perf_event.c and arch/mips/kernel/perf_event_mipsxx.c were divided in a seemingly ad hoc manner, with the first including the second. I moved all the hardware counter support code to perf_event_mipsxx.c and removed the gating #ifdefs to the Kconfig and Makefile. Now perf_event.c contains only the callchain support, everything else is in perf_event_mipsxx.c There are no code changes, only moving of functions from one file to the other, or removing empty unneeded functions.

2011-10-20Revert "MIPS: LD/SD o32 macro GAS fix update"Ralf Baechle
This reverts commit 97475f8b42e83be2966aa2d70ab9c98477701c53 (lmo) / 82b89152f00f7ad17844d5614d5011e8d7944ac9 (kernel.org) [MIPS: LD/SD o32 macro GAS fix update]. Turns out this patch is producing many build errors with gcc 4.2. Based on further testing with a test case extracted from the build errors found further build errors and suboptimal generation even in violation of the "R" constraint. To make matters worse, the binutils changes also don't work quite as intended so revert this patch for now.

2011-10-06x86/PCI: use host bridge _CRS info on ASUS M2V-MX SEPaul Menzel
In summary, this DMI quirk uses the _CRS info by default for the ASUS M2V-MX SE by turning on `pci=use_crs` and is similar to the quirk added by commit 2491762cfb47 ("x86/PCI: use host bridge _CRS info on ASRock ALiveSATA2-GLAN") whose commit message should be read for further information. Since commit 3e3da00c01d0 ("x86/pci: AMD one chain system to use pci read out res") Linux gives the following oops: parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE] HDA Intel 0000:20:01.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 HDA Intel 0000:20:01.0: setting latency timer to 64 BUG: unable to handle kernel paging request at ffffc90011c08000 IP: [<ffffffffa0578402>] azx_probe+0x3ad/0x86b [snd_hda_intel] PGD 13781a067 PUD 13781b067 PMD 1300ba067 PTE 800000fd00000173 Oops: 0009 [#1] SMP last sysfs file: /sys/module/snd_pcm/initstate CPU 0 Modules linked in: snd_hda_intel(+) snd_hda_codec snd_hwdep snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_midi snd_rawmidi snd_seq_midi_event tpm_tis tpm snd_seq tpm_bios psmouse parport_pc snd_timer snd_seq_device parport processor evdev snd i2c_viapro thermal_sys amd64_edac_mod k8temp i2c_core soundcore shpchp pcspkr serio_raw asus_atk0110 pci_hotplug edac_core button snd_page_alloc edac_mce_amd ext3 jbd mbcache sha256_generic cryptd aes_x86_64 aes_generic cbc dm_crypt dm_mod raid1 md_mod usbhid hid sg sd_mod crc_t10dif sr_mod cdrom ata_generic uhci_hcd sata_via pata_via libata ehci_hcd usbcore scsi_mod via_rhine mii nls_base [last unloaded: scsi_wait_scan] Pid: 1153, comm: work_for_cpu Not tainted 2.6.37-1-amd64 #1 M2V-MX SE/System Product Name RIP: 0010:[<ffffffffa0578402>] [<ffffffffa0578402>] azx_probe+0x3ad/0x86b [snd_hda_intel] RSP: 0018:ffff88013153fe50 EFLAGS: 00010286 RAX: ffffc90011c08000 RBX: ffff88013029ec00 RCX: 0000000000000006 RDX: 0000000000000000 RSI: 0000000000000246 RDI: 0000000000000246 RBP: ffff88013341d000 R08: 0000000000000000 R09: 0000000000000040 R10: 0000000000000286 R11: 0000000000003731 R12: ffff88013029c400 R13: 0000000000000000 R14: 0000000000000000 R15: ffff88013341d090 FS: 0000000000000000(0000) GS:ffff8800bfc00000(0000) knlGS:00000000f7610ab0 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: ffffc90011c08000 CR3: 0000000132f57000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process work_for_cpu (pid: 1153, threadinfo ffff88013153e000, task ffff8801303c86c0) Stack: 0000000000000005 ffffffff8123ad65 00000000000136c0 ffff88013029c400 ffff8801303c8998 ffff88013341d000 ffff88013341d090 ffff8801322d9dc8 ffff88013341d208 0000000000000000 0000000000000000 ffffffff811ad232 Call Trace: [<ffffffff8123ad65>] ? __pm_runtime_set_status+0x162/0x186 [<ffffffff811ad232>] ? local_pci_probe+0x49/0x92 [<ffffffff8105afc5>] ? do_work_for_cpu+0x0/0x1b [<ffffffff8105afc5>] ? do_work_for_cpu+0x0/0x1b [<ffffffff8105afd0>] ? do_work_for_cpu+0xb/0x1b [<ffffffff8105fd3f>] ? kthread+0x7a/0x82 [<ffffffff8100a824>] ? kernel_thread_helper+0x4/0x10 [<ffffffff8105fcc5>] ? kthread+0x0/0x82 [<ffffffff8100a820>] ? kernel_thread_helper+0x0/0x10 Code: f4 01 00 00 ef 31 f6 48 89 df e8 29 dd ff ff 85 c0 0f 88 2b 03 00 00 48 89 ef e8 b4 39 c3 e0 8b 7b 40 e8 fc 9d b1 e0 48 8b 43 38 <66> 8b 10 66 89 14 24 8b 43 14 83 e8 03 83 f8 01 77 32 31 d2 be RIP [<ffffffffa0578402>] azx_probe+0x3ad/0x86b [snd_hda_intel] RSP <ffff88013153fe50> CR2: ffffc90011c08000 ---[ end trace 8d1f3ebc136437fd ]--- Trusting the ACPI _CRS information (`pci=use_crs`) fixes this problem. $ dmesg | grep -i crs # with the quirk PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug The match has to be against the DMI board entries though since the vendor entries are not populated.

To be safe though the check is tightened to only take effect when the BIOS from American Megatrends is used. 15:13 < ruik> but coreboot does not need that 15:13 < ruik> because i have there only one root bus 15:13 < ruik> the audio is behind a bridge $ sudo dmidecode BIOS Information Vendor: American Megatrends Inc.

2011-10-01ARM: 7113/1: mm: Align bank start to MAX_ORDER_NR_PAGESLinus Walleij
The VM subsystem assumes that there are valid memmap entries from the bank start aligned to MAX_ORDER_NR_PAGES. On the Ux500 we have a lot of mem=N arguments on the commandline triggering this bug several times over and causing kernel oops messages.
