ibmphp driver currently maps only 1KB of ebda memory area into kernel address
space during driver initialization. This causes kernel oops when the driver is
modprobe'd and it accesses memory beyond 1KB within ebda segment. The first
byte of ebda segment actually stores the length of the ebda region in
Kilobytes. Hence make use of the length parameter and map the entire ebda
region.Signed-off-by: Chandru Siddalingappa

Now that we return the new resource start position, there is no
need to update "struct resource" inside the align function.
Therefore, mark the struct resource as const.Cc: Bjorn Helgaas

Currently, drivers/pci/quirks.c is built unconditionally, but if
CONFIG_PCI_QUIRKS is unset, the only things actually built in this
file are definitions of global variables and empty functions (due to
the #ifdef CONFIG_PCI_QUIRKS embracing all of the code inside the
file). This is not particularly nice and if someone overlooks
the #ifdef CONFIG_PCI_QUIRKS, build errors are introduced.To clean that up, move the definitions of the global variables in
quirks.c that are always built to pci.c, move the definitions of
the empty functions (compiled when CONFIG_PCI_QUIRKS is unset) to
headers (additionally make these functions static inline) and modify
drivers/pci/Makefile so that quirks.c is only built if
CONFIG_PCI_QUIRKS is set.Signed-off-by: Rafael J. Wysocki

Move the max_bus_speed and cur_bus_speed into the pci_bus. Expose the
values through the PCI slot driver instead of the hotplug slot driver.

These enums must not overlap anyway, since we only have a single
pci_bus_speed_strings array. Use a single enum, and move it to
pci.h. Add 'SPEED' to the pcie names to make it clear what they are.Signed-off-by: Matthew Wilcox
Signed-off-by: Jesse Barnes -
The Alternate Routing-ID Interpretation capability allows a single device
to have up to 256 functions. They can be populated sparsely, so the
current technique of scanning every eighth function is not guaranteed
to find them all. By introducing a 'next_fn' function pointer, we can
use the linked list of functions in the ARI capability to scan all the
functions which exist.We can then speed up the pci_scan_slot by skipping the scan of subsequent
devfns for PCIe devices which are the direct children of Root Ports or
Downstream Ports. These devices are only permitted to implement device
0, unless they are ARI devices, in which case they'll be scanned by the
ARI code above.Signed-off-by: Matthew Wilcox

Commit 84b79f8d2882b0a84330c04839ed4d3cefd2ff77 (drm/i915: Fix crash
while aborting hibernation) attempted to fix a regression introduced
by commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915:
implement new pm ops for i915), but it went too far trying to split
the freeze/suspend and resume/thaw parts of the code. As a result,
it introduced another regression, which only is visible on some systems.Fix the problem by merging i915_drm_suspend() with
i915_drm_freeze() and moving some code from i915_resume()
into i915_drm_thaw(), so that intel_opregion_free() and
intel_opregion_init() are also executed in the freeze and thaw code
paths, respectively.Signed-off-by: Rafael J. Wysocki

sparc32: Fix struct stat uid/gid types. -
Commit 085219f79cad89291699bd2bfb21c9fdabafe65f
("sparc32: use proper types in struct stat")Accidently changed the struct stat uid/gid members
to uid_t and gid_t, but those get set to
__kernel_uid32_t and __kernel_gid32_t respectively.
Those are of type 'int' but the structure is meant
to have 'short'. So use uid16_t and gid16_t to
correct this.Reported-by: Rob Landley

Some glibc versions intentionally create lots of alignment faults in
their gconv code, which if not fixed up, results in segfaults during
boot. This can prevent systems booting properly.There is no clear hard-configurable default for this; the desired
default depends on the nature of the userspace which is going to be
booted.So, provide a way for the alignment fault handler to be configured via
the kernel command line.Signed-off-by: Russell King

cachefiles_delete_object() can race with rename. It gets the parent directory
of the object it's asked to delete, then locks it - but rename may have changed
the object's parent between the get and the completion of the lock.However, if such a circumstance is detected, we abandon our attempt to delete
the object - since it's no longer in the index key path, it won't be seen
again by lookups of that key. The assumption is that cachefilesd may have
culled it by renaming it to the graveyard for later destruction.Signed-off-by: David Howells

When polled input device is opened and closed and there are no other
users of polled device, the workqueue is created and destroyed in
every open / close operation. It is probable that at some point
dynamic allocation of internal parts of the workqueue cause changes to the
workqueue.When a work is queued to the workqueue the work struct contains pointers
to the workqueue data. If the workqueue has been changed and the work
has never been queued to the new workqueue, work-struct contains pointers
to the non-existing workqueue. This will cause crash at the work
cancellation during device close since cancellation of a work assumes
that the workqueue exists.To prevent that, work struct is cleaned up at device close. This keeps
work struct clean for the next use.Signed-off-by: Samu Onkalo
