Commit 86cf898e ("intel-iommu: Check for 'DMAR at zero' BIOS error earlier.") was supposed to work by pretending not to detect an IOMMU if it was actually being reported by the BIOS at physical address zero. However, the intel_iommu_init() function is called unconditionally, as are the corresponding functions for other IOMMU hardware. So the patch only worked if you have RAM above the 4GiB boundary. It caused swiotlb to be initialised when no IOMMU was detected during early boot, and thus the later IOMMU init would refuse to run. But if you have less RAM than that, swiotlb wouldn't get set up and the IOMMU _would_ still end up being initialised, even though we never claimed to detect it. This patch also sets the dmar_disabled flag when the error is detected during the initial detection phase -- so that the later call to intel_iommu_init() will return without doing anything, regardless of whether swiotlb is used or not.

Doing the strcmp return value as signed char __res = *cs - *ct; is wrong for two reasons. The subtraction can overflow because __res doesn't use a type big enough. Moreover the compared bytes should be interpreted as unsigned char as specified by POSIX. The same problem is fixed in strncmp.

Dave, Attached is an update of my patch against the cpufreq fixes branch. Before applying the patch I compiled and booted the tree to see if the panic was still there -- to my surprise it was not. This is because of the conversion of cpufreq_cpu_governor to a char[]. While the panic is kaput, the problem of stale data continues and my patch is still valid. It is possible to end up with the wrong governor after hotplug events because CPUFREQ_DEFAULT_GOVERNOR is statically linked to a default, while the cpu siblings may have had a different governor assigned by a user. ie) the patch is still needed in order to keep the governors assigned properly when hotplugging devices Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Dave Jones <davej@redhat.com>

Currently on governer backup/restore path we storing governor's pointer. This is wrong because one may unload governor's module after cpu goes offline. As result use-after-free will take place on restored cpu. It is not easy to exploit this bug, but still we have to close this issue ASAP.

Also, once system is blacklisted, don't repeat checks to see if blacklisted. This also causes the message to only be printed once, rather than for each CPU. Signed-off-by: John L.
