Fuqian Huang 672a749b4d sgi-xpc: Use GFP_ATOMIC for kmalloc in atomic context.
xpc_send_activate_IRQ_uv is called from
 <-xpc_send_activate_IRQ_part_uv
 <-xpc_indicate_partition_disengaged_uv
  (xpc_arch_ops.indicate_partition_disengaged)
 <-xpc_die_deactivate
 <-xpc_system_die

xpc_system_die is registered by atomic_notifier_chain_register,
which indicates xpc_system_die may be called in atomic context.
So the kmalloc in xpc_send_activate_IRQ_uv may be in atomic context.

Use GFP_ATOMIC instead of GFP_KERNEL in kmalloc.

README

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.
