Bruce Ashfield 76586fd877 linux-yocto/5.10: fix qemumips testimage failures
Integrating the following commit(s) to linux-yocto/5.10:

    513e9332a00 qemumips32: disable CONFIG_COMPACTION

As mentioned in yocto bug: https://bugzilla.yoctoproject.org/show_bug.cgi?id=13992
testimages are failing due to issues with kernel page migration/compaction
function that does not work very well with MIPS kernel HIGHMEM that
is needed for 512Mb.

A valid workaround is to disable CONFIG_COMPACTION and the problematic
migration functionality is also disabled.

[YOCTO: #13992]

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
