* PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine2014-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

| * ARM: avoid ARM binutils leaking ELF local symbolsRussell King2014-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Symbols starting with .L are ELF local symbols and should not appear in ELF symbol tables. However, unfortunately ARM binutils leaks the .LANCHOR symbols into the symbol table, which leads kallsyms to report these symbols rather than the real name. It is not very useful when %pf reports symbols against these leaked .LANCHOR symbols. Arrange for kallsyms to ignore these symbols using the same mechanism that is used for the ARM mapping symbols.

This ensures that when hwrng_register() is successful, and it requests a few random bytes to seed the kernel's pool at init, we're ready to service that request. This will also enable us to remove the workaround added previously to check whether probe was completed, and only then ask for data from the host. The revert follows in the next commit. There's a slight behaviour change here on unsuccessful hwrng_register(). Previously, when hwrng_register() failed, the probe() routine would fail, and the vqs would be torn down, and driver would be marked not initialized. Now, the vqs will remain initialized, driver would be marked initialized as well, but won't be available in the list of RNGs available to hwrng core. To fix the failures, the procedure remains the same, i.e. unload and re-load the module, and hope things succeed the next time around.

* | Revert "proc: Point /proc/{mounts,net} at /proc/thread-self/{mounts,net} ↵Linus Torvalds2014-08-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | instead of /proc/self/{mounts,net}" This reverts commits 344470cac42e and e81324407269. It turns out that the exact path in the symlink matters, if for somewhat unfortunate reasons: some apparmor configurations don't allow dhclient access to the per-thread /proc files. As reported by Jörg Otte: audit: type=1400 audit(1407684227.003:28): apparmor="DENIED" operation="open" profile="/sbin/dhclient" name="/proc/1540/task/1540/net/dev" pid=1540 comm="dhclient" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 so we had better revert this for now. We might be able to work around this in practice by only using the per-thread symlinks if the thread isn't the thread group leader, and if the namespaces differ between threads (which basically never happens). We'll see. In the meantime, the revert was made to be intentionally easy. Reported-by: Jörg Otte <jrg.otte@gmail.com> Acked-by: Eric W.

This will help with some device flakiness at probe time. For example, some touchpads and touchscreens may be in transition between bootloader and operational mode and may appear at neither address briefly. Adapters, however, have no limit as it depends on when the i2c adapter driver module is loaded. The module may even be loaded manually by the user using modprobe or insmod. By default, set MAX_I2C_DEVICE_DEFERALS to 5.

I tested the original patch on a Pixel that -- surprise, has Google as vendor. *facepalm*. The only other data I can think of to probe on is Google_* in the version string. Checking with our firmware team, all systems should have this and nothing else than Chrome hardware should have the coreboot + Google_* combination to date. So, we'll switch to this. For future platforms we are going to move to using an ACPI device to configure this instead of a DMI table (yay!), so longer-term that will sort itself out.

In addition, simple core power down from a cpuidle driver could, in case of CPU 0 could result in calling functions that are specific to suspend and deeper idle states. This patch fixes the issue by moving those operations outside the CPU PM notifier into suspend and AFTR code paths. This leads to a bit of code duplication, but allows additional code simplification, so in the end more code is removed than added.

| | | * | | ARM: OMAP2+: clock: allow omap2_dpll_round_rate() to round to next-lowest ratePaul Walmsley2014-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the behavior of omap2_dpll_round_rate() to round to either the exact rate requested, or the next lowest rate that the clock is able to provide. This is not an ideal fix, but is intended to provide a relatively safe way for drivers to set PLL rates, until a better solution can be implemented. For the time being, omap3_noncore_dpll_set_rate() is still allowed to set its rate to something other than what the caller requested; but will warn when this occurs.

As he mentioned, a pre-existing bug reared its head a lot more obviously after this lot of changes. It took quite a bit of time to track it down. In any case, Dave suggested I try my luck by sending directly to you this time. Overview: - more code for Tegra GK20A from NVIDIA - probing, reclockig - better fix for Kepler GPUs that have the graphics engine powered off on startup, method courtesy of info provided by NVIDIA - unhardcoding of a bunch of graphics engine setup on Fermi/Kepler/Maxwell, will hopefully solve some issues people have noticed on higher-end models - support for "Zero Bandwidth Clear" on Fermi/Kepler/Maxwell, needs userspace support in general, but some lucky apps will benefit automagically - reviewed/exposed the full object APIs to userspace (finally), gives it access to perfctrs, ZBC controls, various events. More to come in the future. - various other fixes" Acked-by: Dave Airlie <airlied@redhat.com> * 'linux-3.17' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (87 commits) drm/nouveau: expose the full object/event interfaces to userspace drm/nouveau: fix headless mode drm/nouveau: hide sysfs pstate file behind an option again drm/nv50/disp: shhh compiler drm/gf100-/gr: implement the proper SetShaderExceptions method drm/gf100-/gr: remove some broken ltc bashing, for now drm/gf100-/gr: unhardcode attribute cb config drm/gf100-/gr: fetch tpcs-per-ppc info on startup drm/gf100-/gr: unhardcode pagepool config drm/gf100-/gr: unhardcode bundle cb config drm/gf100-/gr: improve initial context patch list helpers drm/gf100-/gr: add support for zero bandwidth clear drm/nouveau/ltc: add zbc drivers drm/nouveau/ltc: s/ltcg/ltc/ + cleanup drm/nouveau: use ram info from nvif_device drm/nouveau/disp: implement nvif event sources for vblank/connector notifiers drm/nouveau/disp: allow user direct access to channel control registers drm/nouveau/disp: audit and version display classes drm/nouveau/disp: audit and version SCANOUTPOS method drm/nv50-/disp: audit and version PIOR_PWR method ...
