Subject: xen/privcmd: add PRIVCMD_MMAPBATCH_V2 ioctl
X-Git-Tag: omap-for-v3.7-rc1/fixes-cpufreq-signed~30^2~13
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ceb90fa0a8008059ecbbf9114cb89dc71a730bb6;p=pandora-kernel.git

xen/privcmd: add PRIVCMD_MMAPBATCH_V2 ioctl

PRIVCMD_MMAPBATCH_V2 extends PRIVCMD_MMAPBATCH with an additional
field for reporting the error code for every frame that could not be
mapped.  libxc prefers PRIVCMD_MMAPBATCH_V2 over PRIVCMD_MMAPBATCH.

Also expand PRIVCMD_MMAPBATCH to return appropriate error-encoding top nibble
in the mfn array.
