The description of befs_load_sb was confusing the kernel-doc system since,
because it starts with /**, it thinks it will document the function with
kernel-doc formatting. Which it isn't.

ag_shift and blocks_per_ag contain the same information in different ways,
same as block_shift and block_size do. It is worth checking this two are
consistent, but since blocks_per_ag isn't documented as mandatory to use
some implementations of befs don't enforce this, so making it non-fatal if
they don't match and just having it as a warning.

befs_btree_find(), the only caller of befs_find_key(), only cares about if
the return from that function is BEFS_BT_MATCH or not. It never uses the
partial match given with BEFS_BT_PARMATCH. Make the overflow return clearer
by having BEFS_BT_OVERFLOW instead of BEFS_BT_PARMATCH.

befs_error() is used in potential errors that could happen in befs to
provide informational log messages. befs_debug() is silent when
CONFIG_BEFS_DEBUG=no, and very verbose when switched on, which is why it is
used for general debugging but not for errors.
Fix a few cases where the befs debug utility usage isn't following the
expected pattern. To make sure we have consistent information in the logs.

Pull ARM fixes from Russell King:
"Three relatively small fixes for ARM:
- Roger noticed that dma_max_pfn() was calculating the upper limit
wrongly, by adding the PFN offset of memory twice.
- A fix from Robin to correct parsing of MPIDR values when the
address size is larger than one BE32 unit.
- A fix from Srinivas to ensure that we do not rely on the boot
loader (or previous Linux kernel) setting the translation table
base register a certain way in the decompressor, which can lead to
crashes"

ARM: 8617/1: dma: fix dma_max_pfn()
ARM: 8616/1: dt: Respect property size when parsing CPUs
If the bootloader uses the long descriptor format and jumps to
kernel decompressor code, TTBCR may not be in a right state.
Before enabling the MMU, it is required to clear the TTBCR.PD0
field to use TTBR0 for translation table walks.
The commit dbece45894 ("ARM: 7501/1: decompressor:
reset ttbcr for VMSA ARMv7 cores") does the reset of TTBCR.N, but
doesn't consider all the bits for the size of TTBCR.N.
Clear TTBCR.PD0 field and reset all the three bits of TTBCR.N to
indicate the use of TTBR0 and the correct base address width.

When discovering the number of VPEs per core, smp_num_siblings will be
incorrect for kernels built without support for the MIPS MultiThreading
(MT) ASE running on systems which implement said ASE. This leads to
accesses to VPEs in secondary cores being performed incorrectly since
mips_cm_vp_id calculates the wrong ID to write to the local "other"
registers. Fix this by examining the number of VPEs in the core as
reported by the CM.
This patch presumes that the number of VPEs will be the same in each
core of the system. As this path only applies to systems with CM version
2.5 or lower, and this property is true of all such known systems, this
is likely to be fine but is described in a comment for good measure.

One final fix before 4.8: there's a memory leak triggered by turning scsi mq
off due to the fact that we assume on host release that the already running
hosts weren't mq based because that's the state of the global flag (even
though they were), so fix it by tracking this on a per host host basis.

This fixes commit d76eebfa17 ("include/linux/property.h: fix build

With that commit we get the following compile error when using the

This needs a '.' to reference the union member. It seems this was just
overlooked here since it is done correctly in similar constructs in
other parts of the original commit.
This fix is in preparation of upcoming commits that will use this macro.
