Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm 

Pull ARM updates from Russell King:
 "Included in these updates are:
   - Performance optimisation to avoid writing the control register at
     every exception.
   - Use static inline instead of extern inline in ftrace code.
   - Crypto ARM assembly updates for big endian
   - Alignment of initrd/.init memory to page sizes when freeing to
     ensure that we fully free the regions
   - Add gcov support
   - A couple of preparatory patches for VDSO support: use
     _install_special_mapping, and randomize the sigpage placement above
     stack.
   - Add L2 ePAPR DT cache properties so that DT can specify the cache
     geometry.
   - Preparatory patch for FIQ (NMI) kernel C code for things like
     spinlock lockup debug.  Following on from this are a couple of my
     patches cleaning up show_regs() and removing an unused (probably
     since 1.x days) do_unexp_fiq() function.
   - Use pr_warn() rather than pr_warning().
   - A number of cleanups (smp, footbridge, return_address)"

* 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (21 commits)
  ARM: 8167/1: extend the reserved memory for initrd to be page aligned

ARM cores often have a separate level 2 cache controller. There are various
implementations of the L2 cache controller with compatible programming models.
Some of the properties that are just prefixed "cache-*" are taken from section
3.7.3 of the ePAPR v1.1 specification which can be found at:
https://www.power.org/wp-content/uploads/2012/06/Power_ePAPR_APPROVED_v1.1.pdf
The ARM L2 cache representation in the device tree should be done as follows:

I/O coherent mode. Valid only when the arm,pl310-cache compatible
string is used.
- interrupts : 1 combined interrupt.
- cache-size : specifies the size in bytes of the cache
- cache-sets : specifies the number of associativity sets of the cache
- cache-block-size : specifies the size in bytes of a cache block
- cache-line-size : specifies the size in bytes of a line in the cache,
if this is not specified, the line size is assumed to be equal to the
cache block size
- cache-id-part: cache id part number to be used if it is not present
on hardware
- wt-override: If present then L2 is forced to Write through mode
