37c5939136 ACPI, PCI, irq: remove interrupt number restriction
The ACPI compiler uses the extended format when used interrupt numbers
are greater than 15. The extended IRQ syntax is 32 bits according to the
ACPI spec. The code supports parsing the extended interrupt numbers.
However, due to used data structure type; the code silently truncates
interrupt numbers greater than 256.

b5bd026954 ACPI, PCI, irq: remove interrupt count restriction
Code currently supports 256 maximum interrupts at this moment. The patch is
reconfiguring the penalty array as a dynamic list to remove this
limitation.

A new penalty linklist has been added for all other interrupts greater than
16. If an IRQ is not found in the link list, an IRQ info structure will be
dynamically allocated on the first access and will be placed on the list
for further reuse. The list will grow by the number of supported interrupts
in the ACPI table rather than having a 256 hard limitation.

f6740c1899 device property: avoid allocations of 0 length
Arrays can not have zero elements by definition of the unified device
properties. If such property comes from outside we should not allow it to pass.
Otherwise memory allocation on 0 length will return non-NULL value, which we
currently don't check.

Prevent memory allocations of 0 length.

22a5b1ddd8 ARM: bcm2835: clarify RASPBERRYPI_FIRMWARE dependency
The firmware driver can be a loadable module, but the power domain
can only be built-in, so we get a build error in an allmodconfig
kernel:

:(.text+0x17e59c): undefined reference to `rpi_firmware_property'
:(.text+0x17e51c): undefined reference to `rpi_firmware_get'
:(.text+0x17e244): undefined reference to `rpi_firmware_property'

This changes the dependency to only allow the power domain code
to be enabled when the firmware driver is built-in. Other users
of the firmware driver may still be loadable modules and not
everyone needs the power domains, so we don't change the firmware
code.

d50866d00f Btrfs: don't leave dangling dentry if symlink creation failed
When we are creating a symlink we might fail with an error after we
created its inode and added the corresponding directory indexes to its
parent inode. In this case we end up never removing the directory indexes
because the inode eviction handler, called for our symlink inode on the
final iput(), only removes items associated with the symlink inode and
not with the parent inode.

Example:

  $ mkfs.btrfs -f /dev/sdi
  $ mount /dev/sdi /mnt
  $ touch /mnt/foo
  $ ln -s /mnt/foo /mnt/bar
  ln: failed to create symbolic link ‘bar’: Cannot allocate memory
  $ umount /mnt
  $ btrfsck /dev/sdi
  Checking filesystem on /dev/sdi

a879719b8c Btrfs: send, don't BUG_ON() when an empty symlink is found
When a symlink is successfully created it always has an inline extent
containing the source path. However if an error happens when creating
the symlink, we can leave in the subvolume's tree a symlink inode without
any such inline extent item - this happens if after btrfs_symlink() calls
btrfs_end_transaction() and before it calls the inode eviction handler
(through the final iput() call), the transaction gets committed and a
crash happens before the eviction handler gets called, or if a snapshot
of the subvolume is made before the eviction handler gets called. Sadly
we can't just avoid this by making btrfs_symlink() call
btrfs_end_transaction() after it calls the eviction handler, because the
later can commit the current transaction before it removes any items from
the subvolume tree (if it encounters ENOSPC errors while reserving space
for removing all the items).

So make send fail more gracefully, with an -EIO error, and print a
message to dmesg/syslog informing that there's an empty symlink inode,
so that the user can delete the empty symlink or do something else
about it.

26922c5909 ARM: s3c: simplify s3c_irqwake_{e,}intallow definition
For a long time, gcc has warned about odd configurations on s3c64xx:

arch/arm/mach-s3c64xx/include/mach/pm-core.h:61:0: warning: "s3c_irqwake_eintallow" redefined

arch/arm/plat-samsung/include/plat/pm.h:49:0: note: this is the location of the previous definition
 #define s3c_irqwake_eintallow 0

The definitions of s3c_irqwake_intallow and s3c_irqwake_eintallow are a
bit consistent between the various platforms. Things have become easier
now that it's only s3c24xx and s3c64xx that use them at all, so I've tried
to rearrange the definitions to make it more obvious what is going on.
