Kernel panic - not syncing: EDAC MC0: Uncorrected Error  (XEN) Domain 0 crashed: 'noreboot' set - not rebooting.

This happens because FERR_NF_FBD bit 28 is not updated on i5000.  Due to
that, both bits 28 and 29 may be equal to one, returning channel = 3.  As

m68knommu: fix invalid flags on coldfire pit clocksource

The m68knommu coldfire pit clocksource looks like it was incorrectly
marked as a continuous clocksource.  Running with it marked as a
continuous clocksource could cause hangs when the system switches to

This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit

entering oneshot mode (disabling highres timers and nohz).

inotify: do not reuse watch descriptors

Since commit 7e790dd5fc937bc8d2400c30a05e32a9e9eef276 ("inotify: fix
error paths in inotify_update_watch") inotify changed the manor in which
it gave watch descriptors back to userspace.  Previous to this commit
inotify acted like the following:

  inotify_add_watch(X, Y, Z) = 1
  inotify_rm_watch(X, 1);
  inotify_add_watch(X, Y, Z) = 2

but after this patch inotify would return watch descriptors like so:

  inotify_add_watch(X, Y, Z) = 1
  inotify_rm_watch(X, 1);
  inotify_add_watch(X, Y, Z) = 1

which I saw as equivalent to opening an fd where

  open(file) = 1;
  close(1);
  open(file) = 1;

seemed perfectly reasonable.  The issue is that quite a bit of userspace
apparently relies on the behavior in which watch descriptors will not be
quickly reused.  KDE relies on it, I know some selinux packages rely on
it, and I have heard complaints from other random sources such as debian
bug 558981.

Although the man page implies what we do is ok, we broke userspace so
this patch almost reverts us to the old behavior.  It is still slightly
racey and I have patches that would fix that, but they are rather large
and this will fix it for all real world cases.  The race is as follows:

 - task1 creates a watch and blocks in idr_new_watch() before it updates
   the hint.
 - task2 creates a watch and updates the hint.
 - task1 updates the hint with it's older wd
 - task removes the watch created by task2
 - task adds a new watch and will reuse the wd originally given to task2

it requires moving some locking around the hint (last_wd) but this should
solve it for the real world and be -stable safe.

As a side effect this patch papers over a bug in the lib/idr code which
is causing a large number WARN's to pop on people's system and many
reports in kerneloops.org.  I'm working on the root cause of that idr
bug seperately but this should make inotify immune to that issue.

net argument to IP6_INC_STATS_BH") put a new version of the same bug
into this function.

Complicating analysis further, this bug can only trigger when network
namespaces are enabled in the build.  When namespaces are turned off,
the dev_net() does not evaluate it's argument, so the dereference

So, for a long time, namespaces couldn't be turned on unless SYSFS was
disabled.  Therefore, this code has largely been disabled except by
people turning it on explicitly for namespace development.

Benjamin Herrenschmidt [Wed, 13 Jan 2010 05:19:34 +0000 (16:19 +1100)]
zlib: Fix build of powerpc boot wrapper

Commit ac4c2a3bbe5db5fc570b1d0ee1e474db7cb22585 broke the build
of all powerpc boot wrappers.

It attempts to add an include of autoconf.h but used the wrong
path for it. It also adds -D__KERNEL__ to our boot wrapper, both
things that we pretty much didn't do on purpose so far.

We want our boot wrapper to remain independent enough of the kernel
for various reasons, one of them being that you can "wrap" an existing
kernel at distro install time which allows to ship one kernel image
and a set of boot wrappers for different platforms, the wrappers
don't have to be built out of the same kernel build tree.

It's also incorrect to do what the patch does in our boot environment
since we may not have a proper alignment exception handler which means
we may not be able to fixup the few cases where an unaligned access will
need SW emulation (depends on the core variant, could be when crossing
page or segment boundaries for example).

This patch fixes it by putting the old code back in and using the
new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
is set, which happens not to be set on powerpc since we don't include
autoconf.h. It also reverts the changes to our boot wrapper Makefile.

This means that x86 should, afaik, keep the optimisations since its
boot wrapper does include autoconf.h and define __KERNEL__ (though I
doubt they make that much different outside of slow embedded processors).

kbuild: really fix bzImage build with non-bash sh

In an x86 build with CONFIG_KERNEL_LZMA enabled and dash as sh,
arch/x86/boot/compressed/vmlinux.bin.lzma ends with
'\xf0\x7d\x39\x00' (16 bytes) instead of the 4 bytes intended and
the resulting vmlinuz fails to boot.  This improves on the
previous behavior, in which the file contained the characters
'-ne ' as well, but not by much.

Previous commits replaced "echo -ne" first with "/bin/echo -ne",
then "printf" in the hope of improving portability, but none of
these commands is guaranteed to support hexadecimal escapes on
POSIX systems.  So use the shell to convert from hexadecimal to
octal.

xen: fix hang on suspend.

In 65f63384 "xen: improve error handling in do_suspend" I said:
    - xs_suspend()/xs_resume() and dpm_suspend_noirq()/dpm_resume_noirq() were not
      nested in the obvious way.
and changed the ordering of the calls as so:
    BEFORE AFTER
    xs_suspend dpm_suspend_noirq
    dpm_suspend_noirq xs_suspend
    *SUSPEND* *SUSPEND*
    dpm_resume_noirq dpm_resume_noirq
    xs_resume xs_resume
Clearly this is not an improvement and I was talking rubbish.

In particular the new ordering is susceptible to a hang if a xenstore write is
in progress at the point at which the suspend kicks in. When the suspend
process calls xs_suspend it tries to take the request_mutex but if a write is
in progress it could be looping in xenbus_xs.c:read_reply() waiting for
something to arrive on &xs_state.reply_list while holding the request_mutex
(taken in the caller of read_reply).

However if we have done dpm_suspend_noirq before xs_suspend then we won't get
any more xenstore interrupts and process_msg() will never be woken up to add
anything to the reply_list.

Fix this by calling xs_suspend before dpm_suspend_noirq. If dpm_suspend_noirq
fails then make sure we go through the xs_suspend_cancel() code path.

lib: Introduce generic list_sort function

There are two copies of list_sort() in the tree already, one in the DRM
code, another in ubifs.  Now XFS needs this as well.  Create a generic
list_sort() function from the ubifs version and convert existing users
to it so we don't end up with yet another copy in the tree.

m68knommu: fix definitions of __pa() and __va()

Fix compilation breakage of all m68knommu targets:

  CC      arch/m68knommu/kernel/asm-offsets.s
In file included from include/linux/sched.h:77,
                 from arch/m68knommu/kernel/asm-offsets.c:12:
include/linux/percpu.h: In function 'per_cpu_ptr_to_phys':
include/linux/percpu.h:161: error: implicit declaration of function 'virt_to_phy

This is broken in linux-2.6.33-rc3.

Change the definitions of __pa() and __va() to not use virt_to_phys()
and phys_to_virt(). Trivial 1:1 conversion required for the non-MMU case.

A side effect if this is that the m68knommu can now use asm/virtconvert.h
for the definition of virt_to_phys() and phys_to_virt().

Also cleaned up the definition of page_to_phys() when moving into
virtconvert.h.
