crypto: xor - Check for osxsave as well as avx in crypto/xor

2013-09-14T14:06:46Z

commit edb6f29464afc65fc73767540b854abf63ae7144 upstream. This affects xen pv guests with sufficiently old versions of xen and sufficiently new hardware. On such a system, a guest with a btrfs root won't even boot. Signed-off-by: John Haxby Signed-off-by: Herbert Xu Reported-by: Michael Marineau Signed-off-by: Greg Kroah-Hartman

Pull powerpc fixes from Ben Herrenschmidt: "Here are 3 bug fixes that should probably go into 3.11 since I'm also tagging them for stable. Once fixes our old /proc/powerpc/lparcfg file which provides partition informations when running under our hypervisor and also acts as a user-triggerable Oops when hot :-( The other two respectively are a one liner to fix a HVSI protocol handshake problem causing the console to fail to show up on a bunch of machines until we reach userspace, which I deem annoying enough to warrant going to stable, and a nasty gcc miscompile causing us to pass virtual instead of physical addresses to the firmware under some circumstances" * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc/hvsi: Increase handshake timeout from 200ms to 400ms. powerpc: Work around gcc miscompilation of __pa() on 64-bit powerpc: Don't Oops when accessing /proc/powerpc/lparcfg without hypervisor

powerpc: Work around gcc miscompilation of __pa() on 64-bit

2013-08-27T06:59:30Z

On 64-bit, __pa(&static_var) gets miscompiled by recent versions of gcc as something like: addis 3,2,.LANCHOR1+4611686018427387904@toc@ha addi 3,3,.LANCHOR1+4611686018427387904@toc@l This ends up effectively ignoring the offset, since its bottom 32 bits are zero, and means that the result of __pa() still has 0xC in the top nibble. This happens with gcc 4.8.1, at least. To work around this, for 64-bit we make __pa() use an AND operator, and for symmetry, we make __va() use an OR operator. Using an AND operator rather than a subtraction ends up with slightly shorter code since it can be done with a single clrldi instruction, whereas it takes three instructions to form the constant (-PAGE_OFFSET) and add it on. (Note that MEMORY_START is always 0 on 64-bit.) CC: Signed-off-by: Paul Mackerras Signed-off-by: Benjamin Herrenschmidt

powerpc: Don't Oops when accessing /proc/powerpc/lparcfg without hypervisor

2013-08-27T06:38:33Z

/proc/powerpc/lparcfg is an ancient facility (though still actively used) which allows access to some informations relative to the partition when running underneath a PAPR compliant hypervisor. It makes no sense on non-pseries machines. However, currently, not only can it be created on these if the kernel has pseries support, but accessing it on such a machine will crash due to trying to do hypervisor calls. In fact, it should also not do HV calls on older pseries that didn't have an hypervisor either. Finally, it has the plumbing to be a module but is a "bool" Kconfig option. This fixes the whole lot by turning it into a machine_device_initcall that is only created on pseries, and adding the necessary hypervisor check before calling the H_GET_EM_PARMS hypercall CC: Signed-off-by: Benjamin Herrenschmidt
