Sine I started testing this branch, I figure I might as well share the results.

Build results:
	total: 133 pass: 115 fail: 18
Failed builds:
	alpha:defconfig
	alpha:allmodconfig
	arm:imx_v6_v7_defconfig
	arm:imx_v4_v5_defconfig
	i386:allyesconfig
	i386:allmodconfig
	m68k:allmodconfig
	mips:nlm_xlp_defconfig
	parisc:a500_defconfig
	powerpc:cell_defconfig
	powerpc:ppc6xx_defconfig
	powerpc:mpc85xx_defconfig
	powerpc:mpc85xx_smp_defconfig
	tile:tilegx_defconfig

Qemu test results:
	total: 24 pass: 23 fail: 1
Failed tests:
	alpha:alpha_defconfig

More information is available at http://server.roeck-us.net:8010/builders.
Note that powerpc failures are counted twice because they are built twice,
once with binutils 2.23 and once with 2.24.

The most scary problem (in my opinion) is the failed mips:nlm_xlp_defconfig
build.  It is caused by 'scsi_netlink : Make SCSI_NETLINK dependent on NET
instead of selecting NET', which effectively disables CONFIG_NET for around
30 configurations (assuming I found them all). The practical impact is that
the affected configurations won't really work anymore, even if they compile.
