01c0757bae Modernize the use of vm_page_unwire(). Since r288122, vm_page_unwire()
has returned TRUE when the wire count transitions to zero, eliminating
the need for callers to inspect the page's wire count.

9fc7a59f2a Stop including sys/types.h from arm's machine/atomic.h, fix the places
where atomic.h was being included without ensuring that types.h (via
param.h) was included first, as required by atomic(9).

d6699bdec3 [vchi] replace non-reproducible __DATE__/__TIME__ with hardcoded string
Although vchiq_build_date and vchiq_build_time are not used in current
vchi driver at the moment, make sure these value will not leak into
build later on if at some point they will be refered in some new
imported code

a89156f53f ARM: Use new ARMv6 naming conventions for cache and TLB functions
in all but ARMv4 specific files.
Expand ARMv6 compatibility stubs in cpu-v4.h. Use physical address
in L2 cache functions if ARM_L2_PIPT is defined.

72683266d0 Fix pagelist bus_dmamap_t map handling. Memory for pagelist is allocated
by bus_dmamem_alloc() which creates associated bus_dmamap_t map for us.
When this memory is freed by bus_dmamem_free(), the map is freed as well.

Thus there is no need to free it explicitly by bus_dmamap_destroy(),
which leads to double freeing.

e88b3f2e48 Fix locking for VCHI driver by matching sleepable/non-sleepable APIs:
- Emulate Linux mutex API using sx(9) locks with only exclusive operations
    instead of mutex(9), in Linux mutexes are sleepable.
- Emulate Linux rwlock_t using rwlock(9) instead of sx(9). rwlock_t
    in Linux are spin locks

ff4cdb1595 Fix cache issues with bulk transfers
- Use pmap_quick_enter_page/pmap_quick_remove_page to bounce non-cacheline
    aligned head and tail fragments
- Switch from static fragment size to configurable one, newer firmware
    passes cache line size as cache_line_size DTB parameter.

With these changes both RPi and RPi2 pass functinal part of vchiq_test

c26ee519d1 Fix BULK read transfer if destination buffer is not cache line-aligned.
We can't use copyout because destination memory is userland address
in another process but we have reference to respective page so map
the page into kernel address space and copy fragments there

fd90e2ed54 CALLOUT_MPSAFE has lost its meaning since r141428, i.e., for more than ten
years for head.  However, it is continuously misused as the mpsafe argument
for callout_init(9).  Deprecate the flag and clean up callout_init() calls
to make them more consistent.

10e99e6057 Do not mark shared structures as __packed, it leads to race condition
If structure packed as __packed clang (and probably gcc) generates
code that loads word fields (e.g. tx_pos)  byte-by-byte and if it's
modified by VideoCore in the same time as ARM loads the value result
is going to be mixed combination of bytes from previous value and
new one.
