mm: ashmem: fix deadlock when system is low on memory When system is low on memory, allocating memory while holding the ashmem_mutex may try to directly reclaim memory. Then ashmem_shrink() is called in same thread. It will deadlock at acquiring ashmem_mutex. This change lets ashmem_shrink() return failure if ashmem_mutex is not available. Memory will be reclaimed from others.

msm: msm_bus: Add support for 64-bit bandwidth requests

With 8974, bandwidth requests are exceeding integer size.
Update ab and ib to ensure values over 4Gbps can be requested.
For 64-bit support, there are four changes in this patch:
Changes in the bus driver structures and functions to
update ab and ib values to uint64.
Updates in client drivers to ensure that the bus APIs
are called with the right types.
Updates to the device-tree. Device-tree nodes don't
provide a clean mechanism to read a combination of u32
and u64 variables within the same property name. So, the
ab and ib values must be specified in kbps instead of
bytes/sec from the device tree. The bus driver function
will convert the ab and ib values read from device-tree
to Mbps.
Change the existing property names to make them consistent
with the convention used by the new property  name, which
abides to the Device Tree convention.
