This series is a follow on to the series posted earlier (archived at [1]).
Patches 01/22 .. 09/22 of this series have been pretty intensively reviewed;
thanks to all who helped. We've modified per feedback, and these should be in
reasonable shape.
Patches 10/22 .. 19/22 of this series have not been very widely reviewed.
We'd very much appreciate eyeballs here.
Patches 20/22 .. 22/22 of this series are specific to the TI Keystone platform.
These are not ready to be merged in. These are being provided here for the sake
of completeness, and to better illustrate the other patches in this series.
These are dependent on the smpops patches (see [2]).
These patches are also available on the following git repository:

Series changelog:
(01/22) ARM: add mechanism for late code patching
(v2) pulled runtime patching code into separate source files
(v2) reordered arguments to patch macros for consistency with assembly
"Rd, Rt, imm" ordering
(v2) added support for mov immediate patching
(v2) cache flush patched instructions instead of entire kernel code
(v2) pack patch table to reduce table volume
(v2) add to module vermagic to reflect abi change
(v2) misc. cleanups in naming and structure
(02/22) ARM: add self test for runtime patch mechanism
(v2) added init-time tests to verify instruction encoding
(03/22) ARM: use late patch framework for phys-virt patching
(v2) move __pv_offset and __pv_phys_offset to C code
(v2) restore conditional init of __pv_offset and __pv_phys_offset
(04/22) ARM: LPAE: use phys_addr_t on virt <--> phys conversion
(v2) fix patched __phys_to_virt() to use 32-bit operand
(v2) convert non-patch __phys_to_virt and __virt_to_phys to inlines to retain
type checking
(05/22) ARM: LPAE: support 64-bit virt_to_phys patching
(v2) use phys_addr_t instead of split high/low phys_offsets
(v2) use mov immediate instead of add to zero when patching in high order
physical address bits
(v2) fix __pv_phys_offset handling for big-endian
(v2) remove set_phys_offset()
(06/22) ARM: LPAE: use signed arithmetic for mask definitions
(07/22) ARM: LPAE: use phys_addr_t in alloc_init_pud()
(08/22) ARM: LPAE: use phys_addr_t in free_memmap()
(v2) unchanged from v1
(09/22) ARM: LPAE: use phys_addr_t for initrd location and size
(v2) revert to unsigned long for initrd size
(10/22) ARM: LPAE: use phys_addr_t in switch_mm()
(v2) use phys_addr_t instead of u64 in switch_mm()
(v2) revert on changes to v6 and v7-2level
(v2) fix register mapping for big-endian in v7-3level
(11/22) ARM: LPAE: use 64-bit accessors for TTBR registers
(v2) restore comment in cpu_set_reserved_ttbr0()
(12/22) ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem
(13/22) ARM: LPAE: factor out T1SZ and TTBR1 computations
(v2) unchanged from v1
(14/22) ARM: LPAE: accomodate >32-bit addresses for page table base
(v2) apply arch_pgd_shift only on lpae
(v2) move arch_pgd_shift definition to asm/memory.h
(v2) revert on changes to non-lpae procs
(v2) add check to ensure that the pgd physical address is aligned at an
ARCH_PGD_SHIFT boundary
(15/22) ARM: mm: use physical addresses in highmem sanity checks
(16/22) ARM: mm: cleanup checks for membank overlap with vmalloc area
(17/22) ARM: mm: clean up membank size limit checks
(18/22) ARM: add virt_to_idmap for interconnect aliasing
(v2) unchanged from v1
(19/22) ARM: recreate kernel mappings in early_paging_init()
(v2) disable on !lpae at compile time
