This reverts commit eb1711bb94991e93669c5a1b5f84f11be2d51ea1.
It blows up the i915 seqno tracking, resulting in the
BUG_ON(seqno == 0);
in i915_wait_request() triggering, which will cause lock-ups.

This adds a default setting for semaphores parameter, and enables
semaphores by default on IVB.For now, as semaphores interaction with VTd causes random issues on
SNB, we do not enable them by default. But they can still be enabled
via the semaphores=1 kernel parameter.v2: enables semaphores on SNB when IO remapping is disabled, with base

We were checking whether the supplied edid matched the connector it was
read from. We do this in case a DDC read returns an EDID for another
device on a multifunction or otherwise interesting card. However, we

This prevents an in-kernel division by zero which happens when we are
asking for i915_chipset_val too quickly, or within a race condition
between the power monitoring thread and userspace accesses via debugfs.The issue can be reproduced easily via the following command:
while ``; do cat /sys/kernel/debug/dri/0/i915_emon_status; doneThis is particularly dangerous because it can be triggered by
a non-privileged user by just reading the debugfs entry.This issue was also found independently by Konstantin Belousov
, who proposed a similar patch.Reported-by: Konstantin Belousov

This fixes an odd bug found on a Dell PowerEdge 1850/0RC130
(BIOS A05 01/09/2006) where all of the modules doing pci_set_dma_mask
would fail with:ata_piix 0000:00:1f.1: enabling device (0005 -> 0007)
ata_piix 0000:00:1f.1: can't derive routing for PCI INT A
ata_piix 0000:00:1f.1: BMDMA: failed to set dma mask, falling back to PIOThe issue was the Xen-SWIOTLB was allocated such as that the end of
buffer was stradling a page (and also above 4GB). The fix was
spotted by Kalev Leonid which was to piggyback on git commit
e79f86b2ef9c0a8c47225217c1018b7d3d90101c "swiotlb: Use page alignment
for early buffer allocation" which:We could call free_bootmem_late() if swiotlb is not used, and
it will shrink to page alignment.So alloc them with page alignment at first, to avoid lose two pages
And doing that fixes the outstanding issue.

number of different devices, which each can appear with a number
of different descriptor sets. Different types of interfaces
can be identified by looking at the subclass and protocol fieldsSubclass 1 protocol 8 is actually the data interface of a CDC
ECM set, with subclass 1 protocol 9 as the control interface.
Neither support serial data communcation, and cannot therefore
be supported by this driver.At the same time, add a few other sets which appear if the
device is configured in "Windows mode" using this modeswitch

Found one system with UEFI/iBFT, kernel does not detect the iBFT during
iscsi_ibft module loading.Root cause: on x86 (UEFI), we are calling of find_ibft_region() much earlier
- specifically in setup_arch() before ACPI is enabled.Try to split acpi checking code out and call that later
At that time ACPI iBFT already get permanent mapped with ioremap.
So isa_virt_to_bus() will get wrong phys from right virt address.
We could just skip that phys address printing.For legacy one, print the found address early.
