Subject: scripts/qemustart: Allow specifying custom kernel for x86
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b0e5e32daa283c2686f529d57360fda828c758bb;p=openwrt%2Fstaging%2Faparcar.git

scripts/qemustart: Allow specifying custom kernel for x86

Currently it's not possible to test boot squashfs root images, so this
patch now allows this use case as well.
