Subject: Add support for MAP_NORESERVE mmap flag.
X-Git-Tag: qemu-xen-4.6.0-rc1~343^2~12
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=e8efd8e71f89b22d0a5028495cc35bd167f92e63;p=qemu-upstream-4.6-testing.git

Add support for MAP_NORESERVE mmap flag.

mmap_flags_tbl contains a list of mmap flags, and how to map them to
the target. This patch adds MAP_NORESERVE, which was missing to the
list.
