* alpha: Use generic show_interrupts()Thomas Gleixner2011-03-292-57/+11
| | | | | | | | | | | | | The only subtle difference is that alpha uses ACTUAL_NR_IRQS and prints the IRQF_DISABLED flag. Change the generic implementation to deal with ACTUAL_NR_IRQS if defined. The IRQF_DISABLED printing is pointless, as we nowadays run all interrupts with irqs disabled. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

* bitops: remove minix bitops from asm/bitops.hAkinobu Mita2011-03-231-2/+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.

| | | | | | | | | | | | As the result of conversions, there are no users of ext2 non-atomic bit operations except for ext2 filesystem itself.

With this patch, the interested callers can distinguish HWPOISON pages from general FAULT pages, while other callers will still get -EFAULT for all these pages, so the user space interface need not to be changed. This feature is needed by KVM, where UCR MCE should be relayed to guest for HWPOISON page, while instruction emulation and MMIO will be tried for general FAULT page.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | This is useful for system management software so that it can kick off things like gettys and everything that's started from a tty, before we reuse it from/for something else or shut it down. Without this ioctl it would have to temporarily become the owner of the tty, then call vhangup() and then give it up again.

| * | futex: Sanitize cmpxchg_futex_value_locked APIMichel Lespinasse2011-03-111-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cmpxchg_futex_value_locked API was funny in that it returned either the original, user-exposed futex value OR an error code such as -EFAULT. This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New helpers: user_statfs() and fd_statfs(), taking userland pathname and descriptor resp. and filling struct kstatfs. Syscalls of statfs family (native, compat and foreign - osf and hpux on alpha and parisc resp.) switched to those. Removes some boilerplate code, simplifies cleanup on errors...
