to handle AB along with IB to be voted on external bus.

Many nvmem providers are not very keen on having default sysfs
nvmem entry, as most of the usecases for them are inside kernel
itself. And in some cases read/writes to some areas in nvmem are
restricted and trapped at secure monitor level, so accessing them
from userspace would result in board reboots.

This patch adds new NVMEM_SYSFS Kconfig to make binary sysfs entry
an optional one. This provision will give more flexibility to users.
This patch also moves existing sysfs code to a new file so that its
not compiled in when its not really required.

set_page_dirty() is racy if the caller has no
reference against page->mapping->host, and if
the page is unlocked. This is because another
CPU could truncate the page off the mapping and
then free the mapping.

Use set_page_dirty_lock() to avoid this race condition.

We often see a BIG/medium task being migrated from gold cluster to
silver cluster during load balance when the gold CPU has 2 tasks
including this BIG task. For example, BIG task wakes up a binder
and binder preempts and running. At this time, the silver CPU pull
the BIG task since the overall utilization is more. The gold CPU
becomes idle immediately and may not be able to pull the medium
task. It can also happen when a pinned kworker runs on the gold
CPU.

When lower capacity CPUs are load balancing and considering to pull
something from a higher capacity group, we should not pull tasks from a
cpu with only one task running as this is guaranteed to impede progress
for that task. If there is more than one task running, load balance in
the higher capacity group would have already made any possible moves to
resolve imbalance and we should make better use of system compute
capacity by moving a task if we still have more than one running.

Entry field from clock data structure gets initialized with
codec data during state transition from MSM_VIDC_CORE_INIT_DONE
to MSM_VIDC_OPEN. When flush is called before this transaction,
it calls msm_clock_data_reset where mentioned field is getting
accessed, which results in uninitialized data access. Add state
check to ensure the command is handled in right sequence.

Currently, if processing an SG table consumes more memory
than can fit in the pre-allocated buffer, then calls to
hyp_assign_table() will fail as if there were not enough
memory available to process the request.

Instead, for every call to hyp assign, allocate enough
memory to process the maximum batch size, and process large
SG tables in pieces, using this memory. This avoids failures
due to large SG tables. Also, since the memory for handling
these requests is now allocated per hyp_assign_table() call,
we can drop the pre-allocated buffer, as it is no longer in
use.

In commit aaf56cab2137 ("mmc: core: power off host if
SD card resume fails"), the mmc host is powered off if
SD card init failed during resume. However, the power
is not turned on before next time SD card detect.
It would not cause malfunction but lead to too many warnings.
This change adds power on to function mmc_sd_detect to make
sure the power is on before send commands to SD card.
