Douglas Anderson d4e44b8a6a drm/msm: Allocate memory for disp snapshot with kvzalloc() 
[ Upstream commit e4a45582db ]

With the "drm/msm: add a display mmu fault handler" series [1] we saw
issues in the field where memory allocation was failing when
allocating space for registers in msm_disp_state_dump_regs().
Specifically we were seeing an order 5 allocation fail. It's not
surprising that order 5 allocations will sometimes fail after the
system has been up and running for a while.

There's no need here for contiguous memory. Change the allocation to
kvzalloc() which should make it much less likely to fail.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
