Date: Mon, 11 Jan 2010 22:26:30 +0100 From: John Kacur <jkacur@...hat.com> To: Thomas Gleixner <tglx@...utronix.de>, lkml <linux-kernel@...r.kernel.org>, Ingo Molnar <mingo@...e.hu> Cc: Clark Williams <williams@...hat.com>, John Kacur <jkacur@...hat.com> Subject: [PATCH 00/26] Convert locks that can't sleep in -rt to raw_spinlock Thomas: Now that your changes that free up the raw_spinlock name are upstream. (described below for other readers) http://lwn.net/Articles/365863/ http://lwn.net/Articles/366608/ I wanted to forward port the preempt-rt patches that convert locks to atomic_spinlocks (rt tree only) to the new scheme. The patches below are a result of that effort. Please queue these up for 2.6.34 upstream, and please pull for preempt-rt You can pull them from git://git.kernel.org/pub/scm/linux/kernel/git/jkacur/jk-2.6.git jk/v2.6.33-rc3-raw-spinlocks Thanks John Kacur (25): xtime_lock: Convert atomic_seqlock to raw_seqlock, fix up all users x86: Convert tlbstate_lock to raw_spinlock sched: Convert thread_group_cputimer lock to raw_spinlock x86: Convert ioapic_lock and vector_lock to raw_spinlocks x86: Convert i8259A_lock to raw_spinlock x86: Convert pci_config_lock to raw_spinlock i8253: Convert i8253_lock to raw_spinlock x86: Convert set_atomicity_lock to raw_spinlock ACPI: Convert c3_lock to raw_spinlock rtmutex: Convert wait_lock and pi_lock to raw_spinlock printk: Convert lock to raw_spinlock genirq: Convert locks to raw_spinlocks trace: Convert various locks to raw_spinlock clocksource: Convert watchdog_lock to raw_spinlock timer_stats: Convert to raw_spinlocks x86: kvm: Convert i8254/i8259 locks to raw_spinlock x86 - nmi: Convert nmi_lock to raw_spinlock cgroups: Convert cgroups release_list_lock to raw_spinlock proportions: Convert spinlocks to raw_spinlocks. percpu_counter: Convert to raw_spinlock oprofile: Convert to raw_spinlock vgacon: Convert vga console lock to raw_spinlock pci-access: Convert pci_lock to raw_spinlock kprobes: Convert to raw_spinlocks softlockup: Convert to raw_spinlocks Thomas Gleixner (1): seqlock: Create raw_seqlock arch/alpha/kernel/time.c | 4 +- arch/arm/kernel/time.c | 12 ++-- arch/arm/oprofile/common.c | 4 +- arch/arm/oprofile/op_model_mpcore.c | 4 +- arch/blackfin/kernel/time.c | 4 +- arch/cris/kernel/time.c | 4 +- arch/frv/kernel/time.c | 4 +- arch/h8300/kernel/time.c | 4 +- arch/ia64/kernel/time.c | 4 +- arch/ia64/xen/time.c | 4 +- arch/m32r/kernel/time.c | 4 +- arch/m68knommu/kernel/time.c | 4 +- arch/mips/include/asm/i8253.h | 2 +- arch/mips/kernel/i8253.c | 14 ++-- arch/mn10300/kernel/time.c | 4 +- arch/parisc/kernel/time.c | 8 +- arch/powerpc/kernel/time.c | 4 +- arch/sparc/kernel/pcic.c | 8 +- arch/sparc/kernel/time_32.c | 12 ++-- arch/x86/include/asm/i8253.h | 2 +- arch/x86/include/asm/i8259.h | 2 +- arch/x86/include/asm/pci_x86.h | 2 +- arch/x86/kernel/apic/io_apic.c | 106 +++++++++++++++++----------------- arch/x86/kernel/apic/nmi.c | 6 +- arch/x86/kernel/apm_32.c | 4 +- arch/x86/kernel/cpu/mtrr/generic.c | 6 +- arch/x86/kernel/i8253.c | 14 ++-- arch/x86/kernel/i8259.c | 30 +++++----- arch/x86/kernel/time.c | 4 +- arch/x86/kernel/visws_quirks.c | 6 +- arch/x86/kvm/i8254.c | 10 ++-- arch/x86/kvm/i8254.h | 2 +- arch/x86/kvm/i8259.c | 30 +++++----- arch/x86/kvm/irq.h | 2 +- arch/x86/kvm/x86.c | 8 +- arch/x86/mm/tlb.c | 8 +- arch/x86/oprofile/nmi_int.c | 4 +- arch/x86/pci/common.c | 2 +- arch/x86/pci/direct.c | 16 +++--- arch/x86/pci/mmconfig_32.c | 8 +- arch/x86/pci/numaq_32.c | 8 +- arch/x86/pci/pcbios.c | 8 +- arch/xtensa/kernel/time.c | 4 +- drivers/acpi/processor_idle.c | 10 ++-- drivers/block/hd.c | 4 +- drivers/input/gameport/gameport.c | 4 +- drivers/input/joystick/analog.c | 4 +- drivers/input/misc/pcspkr.c | 6 +- drivers/oprofile/event_buffer.c | 4 +- drivers/oprofile/oprofilefs.c | 6 +- drivers/pci/access.c | 34 ++++++------ drivers/video/console/vgacon.c | 42 +++++++------- include/linux/init_task.h | 2 +- include/linux/kprobes.h | 2 +- include/linux/oprofile.h | 2 +- include/linux/percpu_counter.h | 2 +- include/linux/proportions.h | 6 +- include/linux/ratelimit.h | 4 +- include/linux/rtmutex.h | 2 +- include/linux/sched.h | 4 +- include/linux/seqlock.h | 86 +++++++++++++++++++++++++++- include/linux/time.h | 2 +- kernel/cgroup.c | 18 +++--- kernel/hrtimer.c | 8 +- kernel/kprobes.c | 34 ++++++------ kernel/posix-cpu-timers.c | 8 +- kernel/printk.c | 42 +++++++------- kernel/sched_stats.h | 12 ++-- kernel/softlockup.c | 6 +- kernel/time.c | 8 +- kernel/time/clocksource.c | 26 ++++---- kernel/time/ntp.c | 8 +- kernel/time/tick-common.c | 8 +- kernel/time/tick-sched.c | 12 ++-- kernel/time/timekeeping.c | 50 ++++++++-------- kernel/time/timer_stats.c | 6 +- kernel/trace/ring_buffer.c | 52 +++++++++--------- kernel/trace/trace.c | 10 ++-- kernel/trace/trace_irqsoff.c | 6 +- lib/percpu_counter.c | 18 +++--- lib/proportions.c | 12 ++-- lib/ratelimit.c | 4 +- sound/drivers/pcsp/pcsp.h | 2 +- sound/drivers/pcsp/pcsp_input.c | 4 +- sound/drivers/pcsp/pcsp_lib.c | 12 ++-- 85 files changed, 535 insertions(+), 457 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
