Prev: Linux 2.6.27.49
Next: Linux 2.6.32.17
From: Greg KH on 2 Aug 2010 15:10 I'm announcing the release of the 2.6.33.7 kernel. All users of the 2.6.33 kernel series should upgrade. This is the last 2.6.33 release, so everyone should be moved to the .34 kernel at this point in time, hopefully the .35 kernel instead of .34 as ..34 is not going to be maintained for much longer. The updated 2.6.33.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.33.y.git and can be browsed at the normal kernel.org git web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.33.y.git;a=summary thanks, greg k-h ------------ Makefile | 2 arch/arm/kernel/kprobes-decode.c | 5 arch/arm/mach-omap2/board-rx51-peripherals.c | 17 ++ arch/arm/mach-realview/Kconfig | 2 arch/arm/mach-realview/include/mach/barriers.h | 8 + arch/ia64/mm/tlb.c | 2 arch/mips/include/asm/mipsregs.h | 9 + arch/mips/math-emu/cp1emu.c | 15 +- arch/powerpc/include/asm/cpm.h | 24 +++ arch/powerpc/kernel/irq.c | 5 arch/powerpc/sysdev/micropatch.c | 12 + arch/sparc/include/asm/stat.h | 4 arch/x86/include/asm/msr-index.h | 1 arch/x86/include/asm/suspend_32.h | 2 arch/x86/include/asm/suspend_64.h | 2 arch/x86/include/asm/system.h | 2 arch/x86/kernel/acpi/cstate.c | 9 + arch/x86/kernel/acpi/sleep.c | 2 arch/x86/kernel/apic/apic.c | 2 arch/x86/kernel/hpet.c | 2 arch/x86/kernel/pci-calgary_64.c | 17 +- arch/x86/kernel/traps.c | 11 + arch/x86/kvm/mmu.c | 5 arch/x86/kvm/svm.c | 96 ++++++++++++++ arch/x86/power/cpu.c | 4 block/cfq-iosched.c | 13 + drivers/acpi/processor_idle.c | 2 drivers/acpi/sleep.c | 157 ------------------------ drivers/ata/ahci.c | 10 + drivers/ata/ata_generic.c | 6 drivers/base/firmware_class.c | 26 +++ drivers/char/agp/amd64-agp.c | 27 ++-- drivers/char/tpm/tpm.h | 1 drivers/char/tpm/tpm_tis.c | 9 + drivers/cpufreq/cpufreq.c | 11 -
