2020-10-20PCI: vmd: Create bus offset configuration helperJon Derrick
Move the bus offset configuration discovery code to a new helper. Modify the bus offset 2-bit decode switch to have a 0 case and a default error case, just in case the field is expanded in future hardware.

2020-10-20SUNRPC: fix copying of multiple pages in gss_read_proxy_verf()Martijn de Gouw
When the passed token is longer than 4032 bytes, the remaining part of the token must be copied from the rqstp->rq_arg.pages. But the copy must make sure it happens in a consecutive way. With the existing code, the first memcpy copies 'length' bytes from argv->iobase, but since the header is in front, this never fills the whole first page of in_token->pages. The mecpy in the loop copies the following bytes, but starts writing at the next page of in_token->pages. This leaves the last bytes of page 0 unwritten. Symptoms were that users with many groups were not able to access NFS exports, when using Active Directory as the KDC.

2020-10-20drm/i915: Reorder hpd init vs. display resumeVille Syrjälä
Currently we call .hpd_irq_setup() directly just before display resume, and follow it with another call via intel_hpd_init() just afterwards. Assuming the hpd pins are marked as enabled during the open-coded call these two things do exactly the same thing (ie. enable HPD interrupts). Which even makes sense since we definitely need working HPD interrupts for MST sideband during the display resume. So let's nuke the open-coded call and move the intel_hpd_init() call earlier. However we need to leave the poll_init_work stuff behind after the display resume as that will trigger display detection while we're resuming. We don't want that trampling over the display resume process. To make this a bit more symmetric we turn this into a intel_hpd_poll_{enable,disable}() pair. So we end up with the following transformation: intel_hpd_poll_init() -> intel_hpd_poll_enable() lone intel_hpd_init() -> intel_hpd_init()+intel_hpd_poll_disable() .hpd_irq_setup()+resume+intel_hpd_init() -> intel_hpd_init()+resume+intel_hpd_poll_disable() If we really would like to prevent all *long* HPD processing during display resume we'd need some kind of software mechanism to simply ignore all long HPDs. Currently we appear to have that just for fbdev via ifbdev->hpd_suspended. Since we aren't exploding left and right all the time I guess that's mostly sufficient. For a bit of history on this, we first got a mechanism to block hotplug processing during suspend in commit 15239099d7a7 ("drm/i915: enable irqs earlier when resuming") on account of moving the irq enable earlier. This then got removed in commit 50c3dc970a09 ("drm/fb-helper: Fix hpd vs. initial config races") because the fdev initial config got pushed to a later point. The second ad-hoc hpd_irq_setup() for resume was added in commit 0e32b39ceed6 ("drm/i915: add DP 1.2 MST support (v0.7)") to be able to do MST sideband during the resume. And finally we got a partial resurrection of the hpd blocking mechanism in commit e8a8fedd57fd ("drm/i915: Block fbdev HPD processing during suspend"), but this time it only prevent fbdev from handling hpd while resuming. v2: Leave the poll_init_work behind v3: Remove the extra intel_hpd_poll_disable() from display reset (Lyude) Add the missing intel_hpd_poll_disable() to display init (Imre) Cc: Lyude Paul <lyude@redhat.com> Cc: Imre Deak <imre.deak@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201013181137.30560-1-ville.syrjala@linux.intel.com Reviewed-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Lyude Paul <lyude@redhat.com>

Rename intel_dp_sink_dpms() to intel_dp_set_power() so one doesn't always have to convert from the DPMS enum values to the actual DP D-states.

2020-10-20clk: qcom: gdsc: Keep RETAIN_FF bit set if gdsc is already onStephen Boyd
If the GDSC is enabled out of boot but doesn't have the retain ff bit set we will get confusing results where the registers that are powered by the GDSC lose their contents on the first power off of the GDSC but thereafter they retain their contents. This is because gdsc_init() fails to make sure the RETAIN_FF bit is set when it probes the GDSC the first time and thus powering off the GDSC causes the register contents to be reset. We do set the RETAIN_FF bit the next time we power on the GDSC, see gdsc_enable(), so that subsequent GDSC power off's don't lose register contents state. Forcibly set the bit at device probe time so that the kernel's assumed view of the GDSC is consistent with the state of the hardware. This fixes a problem where the audio PLL doesn't work on sc7180 when the bootloader leaves the lpass_core_hm GDSC enabled at boot (e.g. to make a noise) but critically doesn't set the RETAIN_FF bit.

But newer versions of GCC no longer have this bug, so only add it for versions of GCC before 5.0.
