[PATCH 0/1] Support running qemu on kernel older then 4.17

[Mark Hatle <mark.hatle@kernel.crashing.org>]

We were attempting to build qemu on an Ubuntu 18.04 system and ran into
an issue where certain (newer) MMAP flags were not defined.  After further
tracking it was determined that QEMU 8.1 moved forward and only supports
usage on kernel 4.17 or newer.

Using the patch included with this, you can build for an older host, but
more importantly you can build an SDK that includes QEMU that will execute
on the 'SDK_OLDEST_KERNEL'.  While I've not gone back and verified things
work on 3.2.0 system, I have verified that Ubuntu 18.04 is working for me.

(Ubuntu 18.04 is kernel 4.15)
