2012-05-19spi: By default setup spi_masters with 1 chipselect and dynamics bus numberGrant Likely
Trivial simplification. Instead of requiring spi master drivers to always set the bus number (even when a dynamic number is desired), this patch modifies spi_alloc_master() to initialize num_chipselect to 1 (because there will always be at least one CS) and bus_num to -1 for dynamic allocation. This simplifies the code needed to be written for drivers. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2012-05-19spi/spi-fsl-spi: reference correct pdata in fsl_spi_cs_controlHerton Ronaldo Krzesinski
Commit 178db7d3, "spi: Fix device unregistration when unregistering the bus master", changed spi device initialization of dev.parent pointer to be the master's device pointer instead of his parent. This introduced a bug in spi-fsl-spi, since its usage of spi device pointer was not updated accordingly. This was later fixed by commit 5039a86, "spi/mpc83xx: fix NULL pdata dereference bug", but it missed another spot on fsl_spi_cs_control function where we also need to update usage of spi device pointer. This change address that.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 linker bug workarounds from Peter Anvin. GNU ld-2.22.52.0.[12] (*) has an unfortunate bug where it incorrectly turns certain relocation entries absolute. Section-relative symbols that are part of otherwise empty sections are silently changed them to absolute. We rely on section-relative symbols staying section-relative, and actually have several sections in the linker script solely for this purpose. See for example http://sourceware.org/bugzilla/show_bug.cgi?id=14052 We could just black-list the buggy linker, but it appears that it got shipped in at least F17, and possibly other distros too, so it's sadly not some rare unusual case. This backports the workaround from the x86/trampoline branch, and as Peter says: "This is not a minimal fix, not at all, but it is a tested code base." * 'x86/ld-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, relocs: When printing an error, say relative or absolute x86, relocs: Workaround for binutils 2.22.52.0.1 section bug x86, realmode: 16-bit real-mode code support for relocs tool (*) That's a manly release numbering system.

2012-05-19NFSv4.1 resend LAYOUTGET on data server invalid layout errorsAndy Adamson
The "invalid layout" class of errors is handled by destroying the layout and getting a new layout from the server. Currently, the layout must be destroyed before a new layout can be obtained. This means that all references (e.g.lsegs) to the "to be destroyed" layout header must be dropped before it can be destroyed. This in turn means waiting for all in flight RPC's using the old layout as well as draining the data server session slot table wait queue. Set the NFS_LAYOUT_INVALID flag to redirect I/O to the MDS while waiting for the old layout to be destroyed.

Tasks sleeping on the slot table waitq wake to the rpc_prepare_task state. Reset the task for io through the MDS if the deviceid is invalid. The reset functions put the io pages through the pageio layer which has the advantage of re-coalescing which allows for the MDS and DS having different r/wsizes.

2012-05-19drm/i915: Enable the PCH PLL for all generations after link trainingChris Wilson
Hidden away within one chipset specific path was the necessary logic to turn on the PLL. This needs to be done everywhere in order for us to drive any display! As such as soon as we tested on a non-CougarPoint chipset, we failed to bring up any DisplayPorts and generated a nice set of assertion failures in the process. At least one part of our logic is working, the part that assumes that we have no idea what we are doing.
