Len Brown 0093cb1199 pnpacpi: fix potential corruption on "pnpacpi: exceeded the max number of IRQ resources 2"
PNP_MAX_IRQ is 2
If a device invokes pnpacpi_parse_allocated_irqresource() 0, 1, or 2 times, we are happy.
The 3rd time, we will fail and print "pnpacpi: exceeded the max number of IRQ resources: 2"
The 4th and subsequent calls (if this ever happened) would silently scribble on
irq_resource[2], which doesn't actualy exist.

David S. Miller 00713e224e leds: Do not guard NEW_LEDS with HAS_IOMEM
The LEDS infrastructure itself does not require anything
that a platform dependant upon HAS_IOMEM.

The individual drivers do, but they are properly guarded
with the necessary platform dependencies.

One can even imagine a hypervisor based LED driver that
a platform without HAS_IOMEM might have.

Ram Pai 2d4d4864ac [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.

Thanks to Al Viro for the help in getting the design right.

Miklos Szeredi a1a2c409b6 [patch 5/7] vfs: mountinfo: allow using process root
Allow /proc/<pid>/mountinfo to use the root of <pid> to calculate
mountpoints.

 - move definition of 'struct proc_mounts' to <linux/mnt_namespace.h>
 - add the process's namespace and root to this structure
 - pass a pointer to 'struct proc_mounts' into seq_operations

In addition the following cleanups are made:

 - use a common open function for /proc/<pid>/{mounts,mountstat}
 - surround namespace.c part of these proc files with #ifdef CONFIG_PROC_FS
 - make the seq_operations structures const

Miklos Szeredi 719f5d7f0b [patch 4/7] vfs: mountinfo: add mount peer group ID
Add a unique ID to each peer group using the IDR infrastructure.  The
identifiers are reused after the peer group dissolves.

The IDR structures are protected by holding namepspace_sem for write
while allocating or deallocating IDs.

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 the following functions:

  seq_dentry()

These are similar to d_path() and seq_path().  But instead of

from the root of the filesystem to a given dentry, ignoring mounts
completely.

Linus Torvalds 934b7024f0 Fix cardbus resource allocation
Commit 884525655d ("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).

Bryan Wu d4ce220d49 i2c-bfin-twi: Just let i2c-bfin-twi driver depends on BLACKFIN
Simply use "depends on BLACKFIN" (which is technically correct) and just
document which machines have the device.

Bryan Wu 74d362e0b3 i2c-bfin-twi: Add missing pin mux operation
Blackfin TWI controller hardware pin should be requested from GPIO port controller
Before BF54x, there is no need to do this. But as long as BF54x and BF52x
are supported by this generic driver, the missing pin mux operation should be
added.
