From 92eb77d0ffbaa71b501a0a8dabf09a351bf4267f Mon Sep 17 00:00:00 2001
From: Daniel Stone <daniel@fooishbar.org>
Date: Thu, 31 Oct 2013 07:25:34 +0000
Subject: Input: evdev - fall back to vmalloc for client event buffer
evdev always tries to allocate the event buffer for clients using
kzalloc rather than vmalloc, presumably to avoid mapping overhead where
possible. However, drivers like bcm5974, which claims support for
reporting 16 fingers simultaneously, can have an extraordinarily large
buffer. The resultant contiguous order-4 allocation attempt fails due
to fragmentation, and the device is thus unusable until reboot.
Try kzalloc if we can to avoid the mapping overhead, but if that fails,
fall back to vzalloc.

btrfs-relocate-csums-properly-with-prealloc-ext.patch
View File

@ -1,60 +0,0 @@
A user reported a problem where they were getting csum errors when running a
balance and running systemd's journal. This is because systemd is awesome and
fallocate()'s its log space and writes into it. Unfortunately we assume that
when we read in all the csums for an extent that they are sequential starting at
the bytenr we care about. This obviously isn't the case for prealloc extents,
where we could have written to the middle of the prealloc extent only, which
means the csum would be for the bytenr in the middle of our range and not the
front of our range. Fix this by offsetting the new bytenr we are logging to
based on the original bytenr the csum was for. With this patch I no longer see
the csum errors I was seeing. Thanks,

From 05104a4e8713b27291c7bb49c1e7e68b4e243571 Mon Sep 17 00:00:00 2001

Subject: iommu: Remove stack trace from broken irq remapping warning
The warning for the irq remapping broken check in intel_irq_remapping.c is
pretty pointless. We need the warning, but we know where its comming from, the
stack trace will always be the same, and it needlessly triggers things like
Abrt. This changes the warning to just print a text warning about BIOS being
broken, without the stack trace, then sets the appropriate taint bit. Since we
automatically disable irq remapping, theres no need to contiue making Abrt jump
at this problem

From: Julian Stecklina <jsteckli@os.info.tu-dresden.de>
Subject: [PATCH] vfio, iommu: Fixed interaction of VFIO_IOMMU_MAP_DMA with IOMMU address limits
The BUG_ON in drivers/iommu/intel-iommu.c:785 can be triggered from userspace via
VFIO by calling the VFIO_IOMMU_MAP_DMA ioctl on a vfio device with any address
beyond the addressing capabilities of the IOMMU. The problem is that the ioctl code
calls iommu_iova_to_phys before it calls iommu_map. iommu_map handles the case that
it gets addresses beyond the addressing capabilities of its IOMMU.
intel_iommu_iova_to_phys does not.
This patch fixes iommu_iova_to_phys to return NULL for addresses beyond what the
IOMMU can handle. This in turn causes the ioctl call to fail in iommu_map and
(correctly) return EFAULT to the user with a helpful warning message in the kernel
log.
