The core irq_set_type() function updates the flow type when the chip callback returns 0. So setting the type is bogus. The new core code allows to update the type in irq_data and return IRQ_SET_MASK_OK_NOCOPY, so the core code will not touch it, except for setting the IRQ_LEVEL flag.

2011-03-25lib, arch: add filter argument to show_mem and fix private implementationsDavid Rientjes1-1/+1
Commit ddd588b5dd55 ("oom: suppress nodes that are not allowed from meminfo on oom kill") moved lib/show_mem.o out of lib/lib.a, which resulted in build warnings on all architectures that implement their own versions of show_mem(): lib/lib.a(show_mem.o): In function `show_mem': show_mem.c:(.text+0x1f4): multiple definition of `show_mem' arch/sparc/mm/built-in.o:(.text+0xd70): first defined here The fix is to remove __show_mem() and add its argument to show_mem() in all implementations to prevent this breakage. Architectures that implement their own show_mem() actually don't do anything with the argument yet, but they could be made to filter nodes that aren't allowed in the current context in the future just like the generic implementation.

2011-03-24crash_dump: export is_kdump_kernel to modules, consolidate elfcorehdr_addr, ↵Olaf Hering1-17/+0
setup_elfcorehdr and saved_max_pfn The Xen PV drivers in a crashed HVM guest can not connect to the dom0 backend drivers because both frontend and backend drivers are still in connected state. To run the connection reset function only in case of a crashdump, the is_kdump_kernel() function needs to be available for the PV driver modules. Consolidate elfcorehdr_addr, setup_elfcorehdr and saved_max_pfn into kernel/crash_dump.c Also export elfcorehdr_addr to make is_kdump_kernel() usable for modules. Leave 'elfcorehdr' as early_param(). This changes powerpc from __setup() to early_param(). It adds an address range check from x86 also on ia64 and powerpc.

2011-03-24bitops: remove minix bitops from asm/bitops.hAkinobu Mita1-14/+0
minix bit operations are only used by minix filesystem and useless by other modules. Because byte order of inode and block bitmaps is different on each architecture like below: m68k: big-endian 16bit indexed bitmaps h8300, microblaze, s390, sparc, m68knommu: big-endian 32 or 64bit indexed bitmaps m32r, mips, sh, xtensa: big-endian 32 or 64bit indexed bitmaps for big-endian mode little-endian bitmaps for little-endian mode Others: little-endian bitmaps In order to move minix bit operations from asm/bitops.h to architecture independent code in minix filesystem, this provides two config options. CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k. CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu, m32r, mips, sh, xtensa). The architectures which always use little-endian bitmaps do not select these options. Finally, we can remove minix bit operations from asm/bitops.h for all architectures.

This makes the little-endian bitops take any pointer types by changing the prototypes and adding casts in the preprocessor macros.

2011-03-21powerpc/ptrace: Remove BUG_ON when full register set not availableMike Wolf2-3/+14
In some cases during a threaded core dump not all the threads will have a full register set. This happens when the signal causing the core dump races with a thread exiting. The race happens when the exiting thread has entered the kernel for the last time before the signal arrives, but doesn't get far enough through the exit code to avoid being included in the core dump. So we get a thread included in the core dump which is never going to go out to userspace again and only has a partial register set recorded Normally we would catch each thread as it is about to go into userspace and capture the full register set then. However, this exiting thread is never going to go out to userspace again, so we have no way to capture its full register set. It doesn't really matter, though, as this is a thread which is effectively already dead. So instead of hitting a BUG() in this case (a really bad choice of action in the first place), we use a poison value for the register values.

2011-03-21powerpc: Make MPIC honor the "pic-no-reset" device tree propertyMeador Inge2-11/+59
This property, defined in the Open PIC binding, tells the kernel not to use the reset bit in the global configuration register. Additionally, its presence mandates that only sources which are actually used (i.e. appear in the device tree) should have their VECPRI bits initialized. Although, "pic-no-reset" can be used for the same use cases that "protected-sources" is covering, the "protected-sources" implementation was left completely intact. This is a more pragmatic approach as there are already several existing systems which use protected sources. If "pic-no-reset" *and* "protected-sources" are both used, however, then "pic-no-reset" takes precedence in terms of the init behavior and the sanity checks done by protected sources will still take place.

2011-03-21powerpc/pci: Fix crash in PCI code on ppc64 when matching device nodesBenjamin Herrenschmidt1-2/+5
Commit b5d937de0367d26f65b9af1aef5f2c34c1939be0 has a bug which causes basically a NULL dereference in the PCI code during boot on ppc64 machines. fetch_dev_dn() is called when dev->dev.of_node is NULL, so using that as the starting point for the search makes no sense. It should instead start from the device node of the PHB. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
