NTB: Correct debugfs to work with more than 1 NTB Device

2013-11-13T03:05:35+00:00

commit 1517a3f21a1dd321f16bcf44204bddff9d21abd0 upstream.

Debugfs was setup in NTB to only have a single debugfs directory.  This
resulted in the leaking of debugfs directories and files when multiple
NTB devices were present, due to each device stomping on the variables
containing the previous device's values (thus preventing them from being
freed on cleanup).  Correct this by creating a secondary directory of
the PCI BDF for each device present, and nesting the previously existing
information in those directories.

NTB: Correct USD/DSD Identification

2013-11-13T03:05:34+00:00

commit b6750cfe0710a14fd147ba27fddbecae8ba88c77 upstream.

Due to ambiguous documentation, the USD/DSD identification is backward
when compared to the setting in BIOS.  Correct the bits to match the
BIOS setting.

NTB: Correct Number of Scratch Pad Registers

2013-11-13T03:05:34+00:00

commit 87034511519815259e37336f52edf06d114d43b6 upstream.

The NTB Xeon hardware has 16 scratch pad registers and 16 back-to-back
scratch pad registers.  Correct the #define to represent this and update
the variable names to reflect their usage.

NTB: Add Error Handling in ntb_device_setup

2013-11-13T03:05:34+00:00

commit 3b12a0d15bd1559e72ad21d9d807fd2a6706f0ab upstream.

If an error is encountered in ntb_device_setup, it is possible that the
spci_cmd isn't populated.  Writes to the offset can result in a NULL
pointer dereference.  This issue is easily encountered by running in
NTB-RP mode, as it currently is not supported and will generate an
error.  To get around this issue, return if an error is encountered
prior to attempting to write to the spci_cmd offset.

to the core ioctl structs as well, for we found one instance where there
is a 32-/64-bit size mismatch and were guilty of writing beyond the end
of the user's buffer.

drm/vmwgfx: Don't kill clients on VT switch

2013-11-13T03:05:34+00:00

commit c4249855ac5b2a383704d31e040d3831d6a25c6f upstream.

DRI clients that tried to grab the TTM lock when the master (X server) was
switched away during a VT switch were sent the SIGTERM signal by the
kernel. Fix this so that they are only sent that signal when the master has
exited.

clk: fixup argument order when setting VCO parameters

2013-11-13T03:05:33+00:00

commit 2f9f64bc5aa31836810cd25301aa4772ad73ebab upstream.

The order of arguments in the call to vco_set() for the ICST clocks appears to
have been switched in error, which results in the VCO not being initialised
correctly. This in turn stops the integrated LCD on things like Integrator/CP
from working correctly.

This patch fixes the order and restores the expected functionality.
