2012-03-23x86/io_apic: Move and reenable irq only when CONFIG_GENERIC_PENDING_IRQ=yAlexander Gordeev
This patch removes dead code from certain .config variations. When CONFIG_GENERIC_PENDING_IRQ=n irq move and reenable code is never get executed, nor do_unmask_irq variable updates its init value. Move the code under CONFIG_GENERIC_PENDING_IRQ macro.

2012-03-23x86/apic: Add separate apic_id_valid() functions for selected apic driversSteffen Persvold
As suggested by Suresh Siddha and Yinghai Lu: For x2apic pre-enabled systems, apic driver is set already early through early_acpi_boot_init()/early_acpi_process_madt()/ acpi_parse_madt()/default_acpi_madt_oem_check() path so that apic_id_valid() checking will be sufficient during MADT and SRAT parsing. For non-x2apic pre-enabled systems, all apic ids should be less than 255. This allows us to substitute the checks in arch/x86/kernel/acpi/boot.c::acpi_parse_x2apic() and arch/x86/mm/srat.c::acpi_numa_x2apic_affinity_init() with apic->apic_id_valid(). In addition we can avoid feigning the x2apic cpu feature in the NumaChip apic code. The following apic drivers have separate apic_id_valid() functions which will accept x2apic type IDs : x2apic_phys x2apic_cluster x2apic_uv_x apic_numachip Signed-off-by: Steffen Persvold <sp@numascale.com> Cc: Suresh Siddha <suresh.b.siddha@intel.com> Cc: Daniel J Blueman <daniel@numascale-asia.com> Cc: Yinghai Lu <yinghai@kernel.org> Cc: Jack Steiner <steiner@sgi.com> Link: http://lkml.kernel.org/r/1331925935-13372-1-git-send-email-sp@numascale.com Signed-off-by: Ingo Molnar <mingo@kernel.org>

2012-03-23microblaze: Handle TLB skip size dynamicallyMichal Simek
This patch fix the problem with rootfs on JFFS2 with early printk console turned on. The origin version used TLB63 for temporary early printk mapping. The code expect that kernel is not able to use all 64 TLB entries till early printk console is remapped by ioremap. After that temporary mapping on TLB63 is silently lost. This expectation give the opportunity to have early console pretty early. Microblaze systems with JFFS2 rootfs with early printk console turned on used more than 64 TLB entries before kernel can remap early console. Based on that kernel does access to bad area because early printk mapping is rewritten. This patch introduces tlb_skip variable which dynamically stores number of skipped TLB entries from the TLB0. skip_tlb=2 means that TLB0 and TLB1 should be skipped. MICROBLAZE_TLB_SKIP defines how many TLB is skipped at the kernel start. They can be used for user purpose. TLB 63 is used for temporary LMB mapping (MICROBLAZE_LMB_TLB_ID). Also clean TLBLO when kernel starts. For specific kernel sizes kernel can use just one TLB. Detect this case and use the second TLB for general purpose. Change _tlbia function to flush TLB entries from tlb_skip to TLB_SIZE. Export tlb_skip size through debugfs. Signed-off-by: Michal Simek <monstr@monstr.eu>

(*) What is it with all these Linuses these days? There's a Linus at google too. Some day I will get myself my own broadsword, and run around screaming "There can be only one". I used to be _special_ dammit. Snif.

git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev Pull libata updates from Jeff Garzik: 1) AHCI regression fix. A recent "make driver conform to spec" change broke on deployed hardware. Make new behavior optional, rather than default, turning it on only for specific embedded platforms that need this. Everybody else runs in the famous "non conformant but working" mode. 2) pata_cmd64x, pata_legacy cleanups 3) new Intel SATA PCI IDs 4) misc minor vendor feature additions * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev: pata_cmd64x: implement sff_irq_check() method pata_cmd64x: implement sff_irq_clear() method pata_cmd64x: use interrupt status from MRDMODE register pata_cmd64x: turn string of *if* statements into *switch* drivers/ata/pata_mpc52xx.c: clean up error handling code ahci_platform: add STRICT_AHCI platform type ahci: move AHCI_HFLAGS() macro to ahci.h ahci: add AHCI_HFLAG_DELAY_ENGINE host flag sata_fsl: add support for interrupt coalsecing feature ata/pata_arasan_cf: Add Hibernation support pata_legacy: correctly mask recovery field for HT6560B ata_piix: IDE-mode SATA patch for Intel Lynx Point DeviceIDs ahci: AHCI-mode SATA patch for Intel Lynx Point DeviceIDs

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen Pull xen updates from Konrad Rzeszutek Wilk: "which has three neat features: - PV multiconsole support, so that there can be hvc1, hvc2, etc; This can be used in HVM and in PV mode. - P-state and C-state power management driver that uploads said power management data to the hypervisor. It also inhibits cpufreq scaling drivers to load so that only the hypervisor can make power management decisions - fixing a weird perf bug. There is one thing in the Kconfig that you won't like: "default y if (X86_ACPI_CPUFREQ = y || X86_POWERNOW_K8 = y)" (note, that it all depends on CONFIG_XEN which depends on CONFIG_PARAVIRT which by default is off). I've a fix to convert that boolean expression into "default m" which I am going to post after the cpufreq git pull - as the two patches to make this work depend on a fix in Dave Jones's tree. - Function Level Reset (FLR) support in the Xen PCI backend. Fixes: - Kconfig dependencies for Xen PV keyboard and video - Compile warnings and constify fixes - Change over to use percpu_xxx instead of this_cpu_xxx" Fix up trivial conflicts in drivers/tty/hvc/hvc_xen.c due to changes to a removed commit. * tag 'stable/for-linus-3.4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen kconfig: relax INPUT_XEN_KBDDEV_FRONTEND deps xen/acpi-processor: C and P-state driver that uploads said data to hypervisor. xen: constify all instances of "struct attribute_group" xen/xenbus: ignore console/0 hvc_xen: introduce HVC_XEN_FRONTEND hvc_xen: implement multiconsole support hvc_xen: support PV on HVM consoles xenbus: don't free other end details too early xen/enlighten: Expose MWAIT and MWAIT_LEAF if hypervisor OKs it. xen/setup/pm/acpi: Remove the call to boot_option_idle_override. xenbus: address compiler warnings xen: use this_cpu_xxx replace percpu_xxx funcs xen/pciback: Support pci_reset_function, aka FLR or D3 support. pci: Introduce __pci_reset_function_locked to be used when holding device_lock. xen: Utilize the restore_msi_irqs hook.
2012-03-22usbnet: consider device busy at each recieved packetOliver Neukum
usbnet should centrally handle busy reporting in the rx path so subdrivers need not worry. This hurts use cases which do rx only or predominantly. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: David S. Miller <davem@davemloft.net>
