2013-05-08MIPS: octeon: Fix GPIO number in IRQ chip private dataAlexander Sverdlin1-3/+2
Current GPIO chip implementation in octeon-irq is still broken, even after upstream commit 87161ccdc61862c8b49e75c21209d7f79dc758e9 (MIPS: Octeon: Fix broken interrupt controller code). It works for GPIO IRQs that have reset-default configuration, but not for edge-triggered ones. The problem is in octeon_irq_gpio_map_common(), which passes modified "hw" variable (which has range of possible values 16..31) as "gpio_line" parameter to octeon_irq_set_ciu_mapping(), which saves it in private data of the IRQ chip. Later, neither octeon_irq_gpio_setup() is able to re-configure GPIOs (cvmx_write_csr() is writing to non-existent CVMX_GPIO_BIT_CFGX), nor octeon_irq_ciu_gpio_ack() is able to acknowledge such IRQ, because "mask" is incorrect. Fix is trivial and has been tested on Cavium Octeon II -based board, including both level-triggered and edge-triggered GPIO IRQs.

2013-05-08MIPS: Remove unneeded volatile from arch/mips/lib/bitops.cDavid Daney1-7/+7
The operations on the bitmap pointers are protected by "memory" clobbering raw_local_irq_{save,restore}(), so there is no need for volatile here. By removing the volatile we get better code generation out of the compiler.

2013-05-08MIPS: Init new mmu_context for each possible CPU to avoid memory corruptionHuacai Chen1-1/+1
Currently, init_new_context() only for each online CPU, this may cause memory corruption when CPU hotplug and fork() happens at the same time. To avoid this, we make init_new_context() cover each possible CPU. Scenario: 1, CPU#1 is being offline; 2, On CPU#0, do_fork() call dup_mm() and copy a mm_struct to the child; 3, On CPU#0, dup_mm() call init_new_context(), since CPU#1 is offline and init_new_context() only covers the online CPUs, child has the same asid as its parent on CPU#1 (however, child's asid should be 0); 4, CPU#1 is being online; 5, Now, if both parent and child run on CPU#1, memory corruption (e.g. segfault, bus error, etc.) will occur.

2013-05-08MIPS: Build uasm-generated code only once to avoid CPU Hotplug problemHuacai Chen4-2/+22
This and the next patch resolve memory corruption problems while CPU hotplug. Without these patches, memory corruption can triggered easily as below: On a quad-core MIPS platform, use "spawn" of UnixBench-5.1.3 (http:// code.google.com/p/byte-unixbench/) and a CPU hotplug script like this (hotplug.sh): while true; do echo 0 >/sys/devices/system/cpu/cpu1/online echo 0 >/sys/devices/system/cpu/cpu2/online echo 0 >/sys/devices/system/cpu/cpu3/online sleep 1 echo 1 >/sys/devices/system/cpu/cpu1/online echo 1 >/sys/devices/system/cpu/cpu2/online echo 1 >/sys/devices/system/cpu/cpu3/online sleep 1 done Run "hotplug.sh" and then run "spawn 10000", spawn will get segfault after a few minutes. This patch: Currently, clear_page()/copy_page() are generated by Micro-assembler dynamically. But they are unavailable until uasm_resolve_relocs() has finished because jump labels are illegal before that. Since these functions are shared by every CPU, we only call build_clear_page()/ build_copy_page() only once at boot time. Without this patch, programs will get random memory corruption (segmentation fault, bus error, etc.) while CPU Hotplug (e.g. one CPU is using clear_page() while another is generating it in cpu_cache_init()). For similar reasons we modify build_tlb_refill_handler()'s invocation. V2: 1, Rework the code to make CPU#0 can be online/offline. 2, Introduce cpu_has_local_ebase feature since some types of MIPS CPU need a per-CPU tlb_refill_handler().

The Kconfig symbol MIPS_DISABLE_OBSOLETE_IDE was added in v2.6.10. It has never been used. Let's remove it. The symbol was originally introduced by the following commit commit 2bfa662b64a7ee593f3039c1d3fd81a7766a63cd Author: Pete Popov <[email protected]> Date: Tue Oct 12 06:24:19 2004 +0000 - Db1550 bug fixes - updated defconfig - updated Kconfig to use DMA_COHERENT since new silicon is coherent Signed-off-by: Paul Bolle <[email protected]> Patchwork: http://patchwork.linux-mips.org/patch/5064/ Acked-by: John Crispin <[email protected]>

2013-05-08MIPS: remove obsolete Kconfig macrosPaul Bolle2-38/+6
The support for PB1100, PB1500, and PB1550 got merged into the code for DB1000 and DB1550 code in v3.7. When that was done the three related Kconfig symbols were dropped. But not all related Kconfig macros were removed. Do so now. Note that the PB1100 code in the Au1100 LCD driver is removed entirely and not converted to use its current Kconfig macro. That is done because the macros it uses (PB1100_G_CONTROL, PB1100_G_CONTROL_BL, and PB1100_G_CONTROL_VDD) are never defined. Actually only one of these was ever defined (PB1100_G_CONTROL) but that define was removed in v2.6.34. So, as far as I can tell, this code could have never compiled.

2013-05-08MIPS: Netlogic: Support for multiple built-in device treesJayachandran C5-8/+158

Kconfig options are provided for each default device tree so that just the needed ones can be selected to be built into the kernel.

2013-05-07rwsem: check counter to avoid cmpxchg callsDavidlohr Bueso1-1/+3
This patch tries to reduce the amount of cmpxchg calls in the writer failed path by checking the counter value first before issuing the instruction. If ->count is not set to RWSEM_WAITING_BIAS then there is no point wasting a cmpxchg call. Furthermore, Michel states "I suppose it helps due to the case where someone else steals the lock while we're trying to acquire sem->wait_lock." Two very different workloads and machines were used to see how this patch improves throughput: pgbench on a quad-core laptop and aim7 on a large 8 socket box with 80 cores. Some results comparing Michel's fast-path write lock stealing (tps-rwsem) on a quad-core laptop running pgbench: | db_size | clients | tps-rwsem | tps-patch | +---------+----------+----------------+--------------+ | 160 MB | 1 | 6906 | 9153 | + 32.5 | 160 MB | 2 | 15931 | 22487 | + 41.1% | 160 MB | 4 | 33021 | 32503 | | 160 MB | 8 | 34626 | 34695 | | 160 MB | 16 | 33098 | 34003 | | 160 MB | 20 | 31343 | 31440 | | 160 MB | 30 | 28961 | 28987 | | 160 MB | 40 | 26902 | 26970 | | 160 MB | 50 | 25760 | 25810 | ------------------------------------------------------ | 1.6 GB | 1 | 7729 | 7537 | | 1.6 GB | 2 | 19009 | 23508 | + 23.7% | 1.6 GB | 4 | 33185 | 32666 | | 1.6 GB | 8 | 34550 | 34318 | | 1.6 GB | 16 | 33079 | 32689 | | 1.6 GB | 20 | 31494 | 31702 | | 1.6 GB | 30 | 28535 | 28755 | | 1.6 GB | 40 | 27054 | 27017 | | 1.6 GB | 50 | 25591 | 25560 | ------------------------------------------------------ | 7.6 GB | 1 | 6224 | 7469 | + 20.0% | 7.6 GB | 2 | 13611 | 12778 | | 7.6 GB | 4 | 33108 | 32927 | | 7.6 GB | 8 | 34712 | 34878 | | 7.6 GB | 16 | 32895 | 33003 | | 7.6 GB | 20 | 31689 | 31974 | | 7.6 GB | 30 | 29003 | 28806 | | 7.6 GB | 40 | 26683 | 26976 | | 7.6 GB | 50 | 25925 | 25652 | ------------------------------------------------------ For the aim7 worloads, they overall improved on top of Michel's patchset.

git://git.kernel.org/pub/scm/linux/kernel/git/sstabellini/xen Pull ARM Xen SMP updates from Stefano Stabellini: "This contains a bunch of Xen/ARM specific changes, including some fixes, SMP support for Xen on ARM, and moving the xenvm machine from mach-vexpress to mach-virt. The non-Xen files that are touched are arch/arm/Kconfig, to select ARM_PSCI on XEN, and arch/arm/boot/dts/Makefile, to build the xenvm DTB if CONFIG_ARCH_VIRT. Highlights: - Move xenvm to mach-virt. - Implement SMP support in Xen on ARM. - Add support for machine reboot and power off via Xen hypercalls" * tag '3.9-rc3-smp-6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/sstabellini/xen: xen/arm: remove duplicated include from enlighten.c xen/arm: use sched_op hypercalls for machine reboot and power off xenvm: add a simple PSCI node and a second cpu xen/arm: XEN selects ARM_PSCI xen: move the xenvm machine to mach-virt xen/arm: SMP support xen/arm: implement HYPERVISOR_vcpu_op xen/arm: actually pass a non-NULL percpu pointer to request_percpu_irq
