Define all IRQs in irqs.h. If some IRQs are sharing one IRQ number, define
them together. If some IRQs are sharing same name with different IRQ number,
define different IRQ.

After introducing pxa930/pxa935 and new silicons, original cpuid rules
of XScale generation 3 can't fit new silicons. Now redefine the rule
of PXA3xx.
Only PXA300/PXA310/PXA320/PXA930/PXA935 are family members of PXA3xx.
PXA930/PXA935 are family members of PXA93x. PXA93x can be considered
as PXA3xx + CP.

This adds a driver for the the 2D graphics accelerator found on PXA3xx
processors. Only resource mapping, interrupt handling and a simple ioctl
handler is done by the kernel part, the rest of the logic is implemented
in DirectFB userspace.
Graphic applications greatly benefit for line drawing, blend, and
rectangle and triangle filling operations.
Benchmarks done on a PXA303 using the df_dok benchmarking tool follow,
where the value in square brackets show the CPU usage during that test.

This is important because on PXA3xx, the physical mapping of SMEMC registers
differs from the one on PXA2xx. In order to get PCMCIA working on both PXA2xx
and PXA320, the PCMCIA driver was adjusted accordingly as well.
Also, various places in the kernel had to be patched to use
__raw_read/__raw_write.

This patch introduces pxa2xx_map_io() and pxa3xx_map_io() to distinguish
between PXA25x/PXA27x and PXA3xx memory mapping.
Also, fixup for platforms broken after introducing pxa{25x,27x}_map_io()
and pxa3xx_map_io() is included.

The camera registers start and range are encoded into the platform
device, and are actually handled by ioremap()'ed, thus the mapping
in pxa_map_io() is not necessary.

On 2.6.37-rc1, garbage collection ioctl of nilfs was broken due to the
commit 263d90cefc7d82a0 ("nilfs2: remove own inode hash used for GC"),
and leading to filesystem corruption.
The patch doesn't queue gc-inodes for log writer if they are reused
through the vfs inode cache. Here, gc-inode is the inode which
buffers blocks to be relocated on GC. That patch queues gc-inodes in
nilfs_init_gcinode() function, but this function is not called when
they don't have I_NEW flag. Thus, some of live blocks are wrongly
overrode without being moved to new logs.
This resolves the problem by moving the gc-inode queueing to an outer
function to ensure it's done right.

This patch allows the pm-qos value to be user configurable by making it as
a module parameter.This will help our customers to configure the pm-qos
value according to the effect in throughput due to the DMA latency problem
which was observed in Intel Pinetrail platforms.
The tested value of '55' will be filled as the default
pm-qos-value incase the user does not specifies pm-qos value as a
module parameter.

The install_special_mapping routine (used, for example, to setup the
vdso) skips the security check before insert_vm_struct, allowing a local
attacker to bypass the mmap_min_addr security restriction by limiting
the available pages for special mappings.
bprm_mm_init() also skips the check, and although I don't think this can
be used to bypass any restrictions, I don't see any reason not to have
the security check.
