2009-01-16x86: load pointer to pda into %gs while brining up a CPUTejun Heo
[ Based on original patch from Christoph Lameter and Mike Travis. ] CPU startup code in head_64.S loaded address of a zero page into %gs for temporary use till pda is loaded but address to the actual pda is available at the point. Load the real address directly instead. This will help unifying percpu and pda handling later on. This patch is mostly taken from Mike Travis' "x86_64: Fold pda into per cpu area" patch. Signed-off-by: Tejun Heo <tj@kernel.org>
2009-01-16x86: make percpu symbols zerobased on SMPTejun Heo
[ Based on original patch from Christoph Lameter and Mike Travis. ] This patch makes percpu symbols zerobased on x86_64 SMP by adding PERCPU_VADDR() to vmlinux.lds.h which helps setting explicit vaddr on the percpu output section and using it in vmlinux_64.lds.S. A new PHDR is added as existing ones cannot contain sections near address zero. PERCPU_VADDR() also adds a new symbol __per_cpu_load which always points to the vaddr of the loaded percpu data.init region. The following adjustments have been made to accomodate the address change. * code to locate percpu gdt_page in head_64.S is updated to add the load address to the gdt_page offset. * __per_cpu_load is used in places where access to the init data area is necessary. * pda->data_offset is initialized soon after C code is entered as zero value doesn't work anymore. This patch is mostly taken from Mike Travis' "x86_64: Base percpu variables at zero" patch. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

Impact: fix build errors Since the SPARSE IRQS changes redefined how the kstat irqs are organized, arch's must use the new accessor function: kstat_incr_irqs_this_cpu(irq, DESC); If CONFIG_SPARSE_IRQS is set, then DESC is a pointer to the irq_desc which has a pointer to the kstat_irqs.

2009-01-13Fix timeouts in sys_pselect7Bernd Schmidt
Since we (Analog Devices) updated our Blackfin kernel to 2.6.28, we've seen occasional 5-second hangs from telnet. telnetd calls select with a NULL timeout, but with the new kernel, the system call occasionally returns 0, which causes telnet to call sleep (5). This did not happen with earlier kernels. The code in sys_pselect7 looks a bit strange, in particular the variable "to" is initialized to NULL, then changed if a non-null timeout was passed in, but not used further. It needs to be passed to core_sys_select instead of &end_time. This bug was introduced by 8ff3e8e85fa6c312051134b3953e397feb639f51 ("select: switch select() and poll() over to hrtimers").

2009-01-13fix early_serial_setup() regressionHelge Deller
Commit b430428a188e8a434325e251d0704af4b88b4711 ("8250: Don't clobber spinlocks.") introduced a regression on the parisc architecture, which broke the handover to the serial port at boottime. early_serial_setup() was changed to only copy a subset of the uart_port fields, and sadly the "type" and "line" fields were forgotten and thus the serial port was not initialized and could not be used for a handover. This patch fixes this by copying the missing fields. As this change to early_serial_setup() doesn't need an initialized spinlock in the uart_port struct any longer, we can drop the spinlock initialization in the superio driver.

2009-01-13x86 PAT: remove CPA WARN_ON for zero ptevenkatesh.pallipadi@intel.com

2009-01-13x86 PAT: return compatible mapping to remap_pfn_range callersvenkatesh.pallipadi@intel.com
Impact: avoid warning message, potentially solve 3D performance regression Change x86 PAT code to return compatible memtype if the exact memtype that was requested in remap_pfn_rage and friends is not available due to some conflict. This is done by returning the compatible type in pgprot parameter of track_pfn_vma_new(), and the caller uses that memtype for page table. Note that track_pfn_vma_copy() which is basically called during fork gets the prot from existing page table and should not have any conflict. Hence we use strict memtype check there and do not allow compatible memtypes. This patch fixes the bug reported here: http://marc.info/?l=linux-kernel&m=123108883716357&w=2 Specifically the error message: X:5010 map pfn expected mapping type write-back for d0000000-d0101000, got write-combining Should go away.

2009-01-13x86, generic: mark complex bitops.h inlines as __always_inlineAndi Kleen
Impact: reduce kernel image size Hugh Dickins noticed that older gcc versions when the kernel is built for code size didn't inline some of the bitops. Mark all complex x86 bitops that have more than a single asm statement or two as always inline to avoid this problem. Probably should be done for other architectures too. Ingo then found a better fix that only requires a single line change, but it unfortunately only works on gcc 4.3. On older gccs the original patch still makes a ~0.3% defconfig difference with CONFIG_OPTIMIZE_INLINING=y. With gcc 4.1 and a defconfig like build: 6116998 1138540 883788 8139326 7c323e vmlinux-oi-with-patch 6137043 1138540 883788 8159371 7c808b vmlinux-optimize-inlining ~20k / 0.3% difference.

2009-01-12IB/iser: Add dependency on INFINIBAND_ADDR_TRANSRandy Dunlap
Fix ib_iser build to depend on INFINIBAND_ADDR_TRANS; if INET=y but IPV6=n, then the RDMA CM is not built but INFINIBAND_ISER can be enabled, leading to: ERROR: "rdma_destroy_id" [drivers/infiniband/ulp/iser/ib_iser.ko] undefined!

2009-01-12IPoIB: Do not join broadcast group if interface is brought downYossi Etigin
Because the ipoib_workqueue is not flushed when ipoib interface is brought down, ipoib_mcast_join() may trigger a join to the broadcast group after priv->broadcast was set to NULL (during cleanup). This will cause the system to be a member of the broadcast group when interface is down. As a side effect, this breaks the optimization of setting the Q_key only when joining the broadcast group.

2009-01-12async: fix __lowest_in_progress()Arjan van de Ven
At 37000 feet somewhere near Greenland I woke up from a half-sleep with the realisation that __lowest_in_progress() is buggy. After landing I checked and there were indeed 2 problems with it; this patch fixes both: * The order of the list checks was wrong * The locking was not correct.

2009-01-12script: improve markup_oops.pl to also decode oopses in modulesArjan van de Ven
There has been some light flamewar on lkml about decoding oopses in modules (as part of the crashdump flamewar). Now this isn't rocket science, just the markup_oops.pl script cheaped out and didn't handle modules. But really; a flamewar all about that?? What happened to C++ in the kernel or reading files from inside the kernel? This patch adds module support to markup_oops.pl; it's not the most pretty perl but it works for my testcases...

2009-01-12ti_usb_3410_5052: support alternate firmwareChris Adams
The TI USB serial driver supports specifying alternate vendor and product IDs (since the chips can and are used in devices under other vendor/product IDs). However, the alternate IDs were not loaded in the combined product table. This patch also adds support for loading alternate firmware for alternate vendor/product IDs.
