Subject: Fix mingw32 and OpenBSD warnings
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=e6e055c9d79c665de200fc46c746d403d3d943ad;p=qemu-xen-4.1-testing.git

Fix mingw32 and OpenBSD warnings

ffsl() is not universally available, so there are these warnings
on both mingw32 and OpenBSD:
/src/qemu/hw/pcie_aer.c: In function 'pcie_aer_update_log':
/src/qemu/hw/pcie_aer.c:399: warning: implicit declaration of function 'ffsl'

Since status field in PCIEAERErr is uint32_t, we can just use ffs() instead.
