b8349b569a ARM: 6112/1: Use the Inner Shareable I-cache and BTB ops on ARMv7 SMP
The standard I-cache Invalidate All (ICIALLU) and Branch Predication
Invalidate All (BPIALL) operations are not automatically broadcast to
the other CPUs in an ARMv7 MP system. The patch adds the Inner Shareable
variants, ICIALLUIS and BPIALLIS, if ARMv7 and SMP.

faa7bc51c1 Check whether the TLB operations need broadcasting on SMP systems
ARMv7 SMP hardware can handle the TLB maintenance operations
broadcasting in hardware so that the software can avoid the costly IPIs.
This patch adds the necessary checks (the MMFR3 CPUID register) to avoid
the broadcasting if already supported by the hardware.

(this patch is based on the work done by Tony Thompson @ ARM)

991da17ec0 arm: Use __INIT macro instead of .text.init.
arm is placing some code in the .text.init section, but it does not
reference that section in its linker scripts.

This change moves this code from the .text.init section to the
.init.text section, which is presumably where it belongs.

93ed397011 [ARM] 5227/1: Add the ENDPROC declarations to the .S files
This declaration specifies the "function" type and size for various
assembly functions, mainly needed for generating the correct branch
instructions in Thumb-2.

2ccdd1e77d [ARM] 4394/1: ARMv7: Add the TLB range operations
We are currently using the ARMv6 operations but need to duplicate some
of the code because of the introduction of the new CPU barrier
instructions in ARMv7.
