This safe location is now in the fixed code area, and also used for certain

If the new value written to the PLL_CTL or VR_CTL register is the
same as the previous value, the PLL wake-up will occur immediately
(PLL is already locked), but the core and system clock will be
bypassed for the PLL_LOCKCNT duration. For this interval, code will
execute at the CLKIN rate instead of at the expected CCLK rate.
Software should guard against this condition by comparing the
current value to the new value before writing the new value.

relocate MAX_SWITCH_{D,I}_CPLBS from the header to the file
where it actually gets used.  this way when we change
CONFIG_MEM_SIZE in our kconfig, we only rebuild one or two files
rather than a whole bunch that implicitly include cplb.h.

this will also remove the ability to clear the swapcount on
the fly, but i really dont think that functionality is important.

ultimate goal is for CONFIG_MEM_SIZE to go away and calculate

Bernd Schmidt [Tue, 22 Apr 2008 23:17:34 +0000]
[Blackfin] arch: fix bug - when using trace buffer with CONFIG_MPU enabled.

There were a couple of problems with the way the trace buffer state
is saved/restored in assembly.  The DEBUG_HWTRACE_SAVE/RESTORE macros
save a value to the stack, which is not immediately obvious; the CPLB
exception code needed changes to load the correct value of the stack
pointer.  The other problem is that the SAVE/RESTORE macros weren't
pushing and popping the value downwards on the stack, but rather moving
it _upwards_, which is of course completely broken.

We also need to make sure there's a matching DEBUG_HWTRACE_RESTORE in
the error case of the CPLB handler.

[patch 6/7] vfs: mountinfo: add /proc/<pid>/mountinfo

[mszeredi@suse.cz] rewrite and split big patch into managable chunks

/proc/mounts in its current form lacks important information:

 - propagation state
 - root of mount for bind mounts
 - the st_dev value used within the filesystem
 - identifier for each mount and it's parent

It also suffers from the following problems:

 - not easily extendable
 - ambiguity of mountpoints within a chrooted environment
 - doesn't distinguish between filesystem dependent and independent options
 - doesn't distinguish between per mount and per super block options

This patch introduces /proc/<pid>/mountinfo which attempts to address
all these deficiencies.

Code shared between /proc/<pid>/mounts and /proc/<pid>/mountinfo is
extracted into separate functions.

IDs are allocated when a previously unshared vfsmount becomes the
first member of a peer group.  When a new member is added to an
existing group, the ID is copied from one of the old members.

IDs are freed when the last member of a peer group is unshared.

Setting the MNT_SHARED flag on members of a subtree is done as a
separate step, after all the IDs have been allocated.  This way an
allocation failure can be cleaned up easilty, without affecting the
propagation state.

Based on design sketch by Al Viro.

Add a unique ID to each vfsmount using the IDR infrastructure.  The

[patch 2/7] vfs: mountinfo: add seq_file_root()

Add a new function:

  seq_file_root()

This is similar to seq_path(), but calculates the path relative to the
given root, instead of current->fs->root.  If the path was unreachable
from root, then modify the root parameter to reflect this.

[patch 1/7] vfs: mountinfo: add dentry_path()

[mszeredi@suse.cz] split big patch into managable chunks

Add the following functions:

  dentry_path()
  seq_dentry()

These are similar to d_path() and seq_path().  But instead of
calculating the path within a mount namespace, they calculate the path
from the root of the filesystem to a given dentry, ignoring mounts
completely.

Fix cardbus resource allocation

Commit 884525655d07fdee9245716b998ecdc45cdd8007 ("PCI: clean up resource
alignment management") didn't set the alignment information for the
cardbus window resources, causing their subsequent allocations to fail
miserably with a message like

  yenta_cardbus 0000:15:00.0: device not available because of BAR 7 [100:1ff] collisions
  yenta_cardbus: probe of 0000:15:00.0 failed with error -16

or similar.

This fixes it and clarifies the code a bit too (we used to have to use
the insane PCI bridge alignment logic that put the alignment in the
"start" field, this makes it use the slightly easier-to-understand
size-based alignment, and allows us to set the resource start to zero
until it gets allocated).

bus_remove_device: be more careful about incomplete initialization

Prevent bus_remove_device() from crashing if dev->knode_bus has not been
initialized before it's called.

This can happen if the device_add() ended up breaking out early due to
an error, for example.

[PATCH] get rid of __exit_files(), __exit_fs() and __put_fs_struct()

The only reason to have separated __...() for those was to keep them inlined
for local users in exit.c.  Since Alexey removed the inline on those, there's
no reason whatsoever to keep them around; just collapse with normal variants.
