This patch introduces busy waiting for pipes similar to network sockets.
When pipe is full or empty a thread busy waits for some microseconds before
sleeping. This avoids the sleep and wakeup overhead and improves
performance in case wakeup happens very fast. It uses a new field in
pipe_inode_info
Introduce pipe_ll_usec field for pipes that indicates the amount of micro
seconds a thread should spin if pipe is empty or full before sleeping. This
is similar to network sockets. Workloads like hackbench in pipe mode
benefits significantly from this by avoiding the sleep and wakeup overhead.

Some battery driver will use the open circuit voltage (OCV) value to look
up the corresponding battery capacity percent in one certain degree Celsius.
Thus this patch provides some battery properties to present the OCV table
temperatures and OCV capacity table values.

This patch adds the binding documentation for Spreadtrum SC27XX series PMICs
fuel gauge unit device, which is used to calculate the battery capacity.

We clear the pte temporarily during read/modify/write update of the pte. If we
take a page fault while the pte is cleared, the application can get SIGBUS. One
such case is with remap_pfn_range without a backing vm_ops->fault callback.
do_fault will return SIGBUS in that case.

Some systems, for example embedded systems, do not generate
enough entropy on boot through interrupts, and boot may be blocked for
several minutes waiting for a call to getrandom to complete.
Currently, random data is read from a hwrng when it is registered,
and is loaded into primary_crng. This d
