Also update the default branch on .gitmodules

Fix a bug in pool selection. Switch to user space version of polling for
xmit functions (without kthread_should_stop)

Handle probe() code path if called from a non-klcd context. Also change
to userspace version of getting a slot for all _user() functions

Cloudlab has a slightly different X520 card compared to d820's X520.

This tries to get a slot without checking if kthread_should_stop()

async_message_send_start() had a check for kthread_should_stop() while
spinning. This check is meaningless and possibly result in null pointer
exception if invoked on user threads. Replace it with a version that
does not do this check for user threads.

Messages from the queue are always peeked from list head which affects
fairness. Fix it by bringing the list peeking into LCD's main loop.

All changes were backported from v4.20.1 kernel

This reverts commit d2cc9a0e.

We do multiple buddy allocations to see if the returned regions are contiguous
and use those one single block.  Make changes in the init routine for
accommodating it.

Add a hack for alloc and merge a number of 4MB chunks from the buddy allocator.
Ideally we should use a contiguous memory allocator.
