If a machine check is pending and the external or I/O interrupt handler returns to userspace io_mcck_pending is going to call s390_handle_mcck. Before this happens a call to TRACE_IRQS_ON was already made since we know that we are going back to userspace and hence interrupts will be enabled. So there was an indication that interrupts are enabled while in reality they are still disabled. s390_handle_mcck will do a local_irq_save/restore pair and confuse lockdep which later complains about inconsistent irq tracing. To solve this just call trace_hardirqs_off before calling s390_handle_mcck and trace_hardirqs_on afterwards. Signed-off-by:

The header file for external interrupts uses the _u16 type. Make sure that _u16 is defined by including linux/types.h. This prevents compile failures, if asm/s390_ext.h is the first include file. Signed-off-by:

There is no need to disable bottom halves when holding call_lock. Also this could imply that it is legal to call smp_call_function* from bh context, which it is not. Also test if func will be executed locally before disabling and aterwards enabling interrupts again. It's not necessary to disable and enable interrupts each time __smp_call_function_map gets called.

smp_call_function_single now has the same semantics as s390's smp_call_function_on. Therefore convert to the *single variant and get rid of some architecture specific code. Signed-off-by:

Commit bd804eba ("PM: Introduce pm_power_off_prepare") caused problems in the poweroff path, as reported by YOSHIFUJI Hideaki / 吉藤英明. Generally, sysdev_shutdown() should be called after the ACPI preparation for powering the system off. To make it happen, we can separate sysdev_shutdown() from device_shutdown() and call it directly wherever necessary. Signed-off-by:

This reverts most of commit 19d36ccd. The way to DEBUG_RODATA interactions with KPROBES and CPU hotplug is to just not mark the text as being write-protected in the first place. Both of those facilities depend on rewriting instructions. Having "helpful" debug facilities that just cause more problem is not being helpful. It just adds complexity and bugs. Not worth it.

With the introduction of kernelcore=, a configurable zone is created on request. In some cases, this value will be small enough that some nodes contain only ZONE_MOVABLE. On some NUMA configurations when this occurs, arch-independent zone-sizing will get the size of the memory holes within the node incorrect. The value of present_pages goes negative and the boot fails. This patch fixes the bug in the calculation of the size of the hole. The test case is to boot test a NUMA machine with a low value of kernelcore= before and after the patch is applied. While this bug exists in early kernel it cannot be triggered in practice. This patch has been boot-tested on a variety machines with and without kernelcore= set. Signed-off-by:

EDAC has a foundation to perform software memory scrubbing, but it requires a per architecture (atomic_scrub) function for performing an atomic update operation. Under X86, this is done with a lock: add [addr],0 in the file asm-x86/edac.h This patch provides the MIPS arch with that atomic function, atomic_scrub() in asm-mips/edac.h Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by:

This patch fixes sysfs exit code for the EDAC PCI device in a similiar manner and the previous fixes for EDAC_MC and EDAC_DEVICE. It removes the old (and incorrect) completion model and uses reference counts on per instance kobjects and on the edac core module. This pattern was applied to the edac_mc and edac_device code, but the EDAC PCI code was missed. In addition, this fixes a system hang after a low level driver was unloaded. (A cleanup function was called twice, which really screwed things up) Cc: Greg KH <greg@kroah.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by:

This fixes a deadlock that could occur on a 'setup' and 'teardown' sequence of the workq for a edac_mc control structure instance. A similiar fix was previously implemented for the edac_device code. In addition, the edac_mc device code there was missing code to allow the workq period valu to be altered via sysfs control. This patch adds that fix on the code, and allows for the changing of the period value as well. Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by:

Nathan Lynch <ntl@pobox.com> reported: 2.6.23-rc1 breaks the build for 64-bit powerpc for me (using maple_defconfig): LD vmlinux.o powerpc64-unknown-linux-gnu-ld: dynreloc miscount for kernel/built-in.o, section .opd powerpc64-unknown-linux-gnu-ld: can not edit opd Bad value make: *** [vmlinux.o] Error 1 However, I see a possibly related binutils patch: http://article.gmane.org/gmane.comp.gnu.binutils/33650 It was tracked down to be caused by the weak prototype declaration in mm.h: __attribute__((weak)) const char *arch_vma_name(struct vm_area_struct *vma); But there is no need to make the declaration weak - only the definition needs to be marked weak. So drop the weak declaration. And in the process drop the duplicate definition in page.h for powerpc. Note: the arch_vma_name fix for x86_64 needs to be applied first to avoid breaking x86_64 Signed-off-by:

ext[234]_check_descriptors sanity checks block group descriptor geometry at mount time, testing whether the block bitmap, inode bitmap, and inode table reside wholly within the blockgroup. However, the inode table test is off by one so that if the last block in the inode table resides on the last block of the block group, the test incorrectly fails. This is because it tests the last block as (start + length) rather than (start + length - 1). This can be seen by trying to mount a filesystem made such as: mkfs.ext2 -F -b 1024 -m 0 -g 256 -N 3744 fsfile 1024 which yields: EXT2-fs error (device loop0): ext2_check_descriptors: Inode table for group 0 not in group (block 101)! EXT2-fs: group descriptors corrupted! There is a similar bug in e2fsprogs, patch already sent for that. (I wonder if inside(), outside(), and/or in_range() should someday be used in this and other tests throughout the ext filesystems...) Signed-off-by:
