2011-10-24x86: Fix S4 regressionTakashi Iwai1-2/+1
Commit 4b239f458 ("x86-64, mm: Put early page table high") causes a S4 regression since 2.6.39, namely the machine reboots occasionally at S4 resume. It doesn't happen always, overall rate is about 1/20. But, like other bugs, once when this happens, it continues to happen. This patch fixes the problem by essentially reverting the memory assignment in the older way. Signed-off-by: Takashi Iwai <tiwai@suse.de> Cc: <stable@kernel.org> Cc: Rafael J.

Currently no type of alignment is specified for PCI expansion roms while parsing the openfirmware tree. This causes calls to pci_map_rom() to fail.

Defaulting to DEBUG_ICEDCC will cause systems to hang during boot unless a hardware debugger is listening to the debug comms. channel.

2011-10-17ARM: 7073/1: debug: augment DEBUG_LL Kconfig help to clarify behaviourWill Deacon1-1/+6
Enabled DEBUG_LL hardcodes the UART address into the kernel and results in a non-portable kernel image. Since this option is only intended for use when debugging early boot failures, supporting multiple platforms in such a configuration is not the intended use-case. This patch documents this limitation in the DEBUG_LL Kconfig help text, so that users are aware of the portability restrictions that are associated with enabling low-level debugging support.

2011-10-17ARM: 7072/1: debug: use kconfig choice for selecting DEBUG_LL UARTWill Deacon1-17/+24
Enabling CONFIG_DEBUG_LL (which is required for earlyprintk) hardwires the debug UART address into the kernel, so that we can print before the platform is initialised. If the user inadvertently selects multiple platforms with DEBUG_LL enabled, the UART address may not be correct and will likely cause the kernel to hang in the very early stages of boot. This patch, based on a skeleton from Russell, uses a Kconfig choice for selecting the DEBUG_LL UART, therefore allowing the user to make a choice about the supported platform when DEBUG_LL is enabled.

2011-10-17ARM: 7011/1: Add ARM cpu topology definitionVincent Guittot6-0/+218
The affinity between ARM processors is defined in the MPIDR register. We can identify which processors are in the same cluster, and which ones have performance interdependency. We can define the cpu topology of ARM platform, that is then used by sched_mc and sched_smt. The default state of sched_mc and sched_smt config is disable. When enabled, the behavior of the scheduler can be modified with sched_mc_power_savings and sched_smt_power_savings sysfs interfaces.

SFI tables reside in RAM and should not be modified once they are written. Current code went to set pentry->irq to zero which causes subsequent reads to fail with invalid SFI table checksum. This will break kexec as the second kernel fails to validate SFI tables. To fix this we use temporary variable for irq number.

2011-10-07x86/PCI: use host bridge _CRS info on ASUS M2V-MX SEPaul Menzel1-0/+11
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. DMI: System manufacturer System Product Name/M2V-MX SE, BIOS 0304 10/30/2007 This quirk should be removed when `pci=use_crs` is enabled for machines from 2006 or earlier or some other solution is implemented. Using coreboot [1] with this board the problem does not exist but this quirk also does not affect it either. 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.

2011-10-06ARM: 7077/1: LPAE: Use a mask for physical addresses in page table entriesCatalin Marinas2-3/+5
With LPAE, the physical address mask is 40-bit while the page table entry is 64-bit. This patch introduces PHYS_MASK for the 2-level page table format, defined as ~0UL. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-10-06ARM: 7076/1: LPAE: Add (pte|pmd)val_t type definitions as u32Catalin Marinas6-56/+59
This patch defines the (pte|pmd)val_t as u32 and changes the page table types to be based on these. The PMD bits are converted to the corresponding type using the _AT macro. The flush_pmd_entry/clean_pmd_entry argument was changed to (void *) to allow them to be used with both PGD and PMD pointers and avoid code duplication.

2011-10-01ARM: OC_ETM should not select ARM_AMBAArnd Bergmann1-1/+1
The CONFIG_ARM_AMBA symbol is selected by the platforms that support AMBA, and the other platforms (e.g. orion) might not be able to build that code at all when they do not support the clk API. Instead, make sure that OC_ETM is only built on platforms that do support the amba subsystem already. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: pci: always export pcibios_bus_to_resourceArnd Bergmann1-5/+4
Some PCI drivers call pcibios_bus_to_resource directly, but it is only exported when CONFIG_HOTPLUG is set, because it was initially mean for pccard support. Moving the export out of the #ifdef lets us avoid these build errors: ERROR: "pcibios_bus_to_resource" [drivers/video/vt8623fb.ko] undefined!
