2014-10-08sb_edac: Claim a different PCI deviceAndy Lutomirski1-1/+1
sb_edac controls a large number of different PCI functions. Rather than registering as a normal PCI driver for all of them, it registers for just one so that it gets probed and, at probe time, it looks for all the others. Coincidentally, the device it registers for also contains the SMBUS registers, so the PCI core will refuse to probe both sb_edac and a future iMC SMBUS driver. The drivers don't actually conflict, so just change sb_edac's device table to probe a different device. An alternative fix would be to merge the two drivers, but sb_edac will also refuse to load on non-ECC systems, whereas i2c_imc would still be useful without ECC. The only user-visible change should be that sb_edac appears to bind a different device.

2014-09-23amd64_edac: Modify usage of amd64_read_dct_pci_cfg()Aravind Gopalakrishnan2-71/+80
Rationale behind this change: - F2x1xx addresses were stopped from being mapped explicitly to DCT1 from F15h (OR) onwards. They use _dct[0:1] mechanism to access the registers. So we should move away from using address ranges to select DCT for these families. - On newer processors, the address ranges used to indicate DCT1 (0x140, 0x1a0) have different meanings than what is assumed currently. Changes introduced: - amd64_read_dct_pci_cfg() now takes in dct value and uses it for 'selecting the dct' - Update usage of the function. Keep in mind that different families have specific handling requirements - Remove [k8|f10]_read_dct_pci_cfg() as they don't do much different from amd64_read_pci_cfg() - Move the k8 specific check to amd64_read_pci_cfg - Remove f15_read_dct_pci_cfg() and move logic to amd64_read_dct_pci_cfg() - Remove now needless .read_dct_pci_cfg Testing: - Tested on Fam 10h; Fam15h Models: 00h, 30h; Fam16h using 'EDAC_DEBUG' and mce_amd_inj - driver obtains info from F2x registers and caches it in pvt structures correctly - ECC decoding works fine Signed-off-by: Aravind Gopalakrishnan <aravind.gopalakrishnan@amd.com> Link: http://lkml.kernel.org/r/1410799058-3149-1-git-send-email-aravind.gopalakrishnan@amd.com Signed-off-by: Borislav Petkov <bp@suse.de>

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: "The main set of series of patches for media subsystem, including: - document RC sysfs class - added an API to setup scancode to allow waking up systems using the Remote Controller - add API for SDR devices. Drivers are still on staging - some API improvements for getting EDID data from media inputs/outputs - new DVB frontend driver for drx-j (ATSC) - one driver (it913x/it9137) got removed, in favor of an improvement on another driver (af9035) - added a skeleton V4L2 PCI driver at documentation - added a dual flash driver (lm3646) - added a new IR driver (img-ir) - added an IR scancode decoder for the Sharp protocol - some improvements at the usbtv driver, to allow its core to be reused. - added a new SDR driver (rtl2832u_sdr) - added a new tuner driver (msi001) - several improvements at em28xx driver to fix PM support, device removal and to split the V4L2 specific bits into a separate sub-driver - one driver got converted to videobuf2 (s2255drv) - the e4000 tuner driver now follows an improved binding model - some fixes at V4L2 compat32 code - several fixes and enhancements at videobuf2 code - some cleanups at V4L2 API documentation - usual driver enhancements, new board additions and misc fixups" [ NOTE! This merge effective drops commit 4329b93b283c ("of: Reduce indentation in of_graph_get_next_endpoint"). The of_graph_get_next_endpoint() function was moved and renamed by commit fd9fdb78a9bf ("[media] of: move graph helpers from drivers/media/v4l2-core to drivers/of"). It was originally called v4l2_of_get_next_endpoint() and lived in the file drivers/media/v4l2-core/v4l2-of.c. In that original location, it was then fixed to support empty port nodes by commit b9db140c1e46 ("[media] v4l: of: Support empty port nodes"), and that commit clashes badly with the dropped "Reduce intendation" commit. I had to choose one or the other, and decided that the "Support empty port nodes" commit was more important ] * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (426 commits) [media] em28xx-dvb: fix PCTV 461e tuner I2C binding Revert "[media] em28xx-dvb: fix PCTV 461e tuner I2C binding" [media] em28xx: fix PCTV 290e LNA oops [media] em28xx-dvb: fix PCTV 461e tuner I2C binding [media] m88ds3103: fix bug on .set_tone() [media] saa7134: fix WARN_ON during resume [media] v4l2-dv-timings: add module name, description, license [media] videodev2.h: add parenthesis around macro arguments [media] saa6752hs: depends on CRC32 [media] si4713: fix Kconfig dependencies [media] Sensoray 2255 uses videobuf2 [media] adv7180: free an interrupt on failure paths in init_device() [media] e4000: make VIDEO_V4L2 dependency optional [media] af9033: Don't export functions for the hardware filter [media] af9035: use af9033 PID filters [media] af9033: implement PID filter [media] rtl2832_sdr: do not use dynamic stack allocation [media] e4000: fix 32-bit build error [media] em28xx-audio: make sure audio is unmuted on open() [media] DocBook media: v4l2_format_sdr was renamed to v4l2_sdr_format ...
