* m32r: fix switch_to macro to push/pop frame pointer if neededHirokazu Takata2007-05-112-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a rarely-happened but severe scheduling problem of the recent m32r kernel of 2.6.17-rc3 or later. In the following previous m32r patch, the switch_to macro was modified not to do unnecessary push/pop operations for tuning. > [PATCH] m32r: update switch_to macro for tuning > 4127272c38619c56f0c1aa01d01c7bd757db70a1 In this modification, only 'lr' and 'sp' registers are push/pop'ed, assuming that the m32r kernel is always compiled with -fomit-frame-pointer option. However, in 2.6 kernel, kernel/sched.c is irregularly compiled with -fno-omit-frame-pointer if CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER is not defined. -- kernel/Makefile -- : ifneq ($(CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER),y) # According to Alan Modra <alan@linuxcare.com.au>, the -fno-omit-frame-pointer is # needed for x86 only. Why this used to be enabled for all architectures is beyond # me. I suspect most platforms don't need this, but until we know that for sure # I turn this off for IA-64 only. Andreas Schwab says it's also needed on m68k # to get a correct value for the wait-channel (WCHAN in ps). --davidm CFLAGS_sched.o := $(PROFILING) -fno-omit-frame-pointer endif : --- Therefore, for the recent m32r kernel, we have to push/pop 'fp' (frame pointer) if CONFIG_FRAME_POINTER is defined or CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER is not defined.

* VM statistics: Make timer deferrableChristoph Lameter2007-05-111-1/+1
| | | | | | | | | | | | | | | | | | | | | VM statistics updates do not matter if the kernel is in idle powersaving mode. So allow the timer to be deferred. It would be better though if we could switch the timer between deferrable and nondeferrable based on differentials present. The timer would start out nondeferrable and if we find that there were no updates in the last statistics interval then we would switch the timer to deferrable. If the timer later finds again that there are differentials then go to nondeferrable again. And yet another way would be to run the timer shortly before going to idle? The solution here means that the VM counters may be slightly off during idle since differentials may be still pending while the timer is deferred.

* AFS: fix a couple of problems with unlinking AFS filesDavid Howells2007-05-114-17/+31
| | | | | | | | | | | | | | | | | | Fix a couple of problems with unlinking AFS files. (1) The parent directory wasn't being updated properly between unlink() and the following lookup(). It seems that, for some reason, invalidate_remote_inode() wasn't discarding the directory contents correctly, so this patch calls invalidate_inode_pages2() instead on non-regular files. (2) afs_vnode_deleted_remotely() should handle vnodes that don't have a source server recorded without oopsing.

* i386: work around miscompilation of alternatives codeJoerg Roedel2007-05-113-2/+16
| | | | | | | | | | | | | | | | | | | A recent change makes my Dell 1501 hang on boot. It's an AMD MK-36. I use an x86_64 kernel. It is 100% reproducible. I debugged this problem a bit and my compiler[1]interprets the =A constraint as %rax instead of %edx:%eax on x86_64 which causes the problem. The appended patch provides a workaround for this and fixed the hang on my machine.

* locks: fix F_GETLK regression (failure to find conflicts)J. Bruce Fields2007-05-101-2/+3
| | | | | | | | | | | | | | | | | | | | | | In 9d6a8c5c213e34c475e72b245a8eb709258e968c we changed posix_test_lock to modify its single file_lock argument instead of taking separate input and output arguments. This makes it no longer safe to set the output lock's fl_type to F_UNLCK before looking for a conflict, since that means searching for a conflict against a lock with type F_UNLCK. This fixes a regression which causes F_GETLK to incorrectly report no conflict on most filesystems (including any filesystem that doesn't do its own locking). Also fix posix_lock_to_flock() to copy the lock type. This isn't strictly necessary, since the caller already does this; but it seems less likely to cause confusion in the future.

| * | | [POWERPC] Fix incorrect calculation of I/O window addressesPaul Mackerras2007-05-101-24/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My patch "Cope with PCI host bridge I/O window not starting at 0" introduced a bug in the calculation of the virtual addresses for the I/O windows of PCI host bridges other than the first, because it didn't account for the fact that hose->io_resource gets offset so that it reflects the range of global I/O port numbers assigned to the bridge. This fixes it and simplifies get_bus_io_range() in the process. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Celleb has multiple PCI host bridges (phbs). Previous boot logic gives non-overlapped bus IDs between PCI host bridges so you can identify PHB by bus ID. But newer boot logic gives same bus ID between PHBs (it gives bus ID 0 as root bus.) So we have to set 'phb->buid' as non-zero. Signed-off-by: Kou Ishizaki <kou.ishizaki@toshiba.co.jp> Signed-off-by: Paul Mackerras <paulus@samba.org>

A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().
