2014-11-27powerpc/powernv: Fix the hmi event version check.Mahesh Salgaonkar1-1/+1
The current HMI event structure is an ABI and carries a version field to accommodate future changes without affecting/rearranging current structure members that are valid for previous versions. The current version check "if (hmi_evt->version != OpalHMIEvt_V1)" doesn't accomodate the fact that the version number may change in future. If firmware starts returning an HMI event with version > 1, this check will fail and no HMI information will be printed on older kernels. This patch fixes this issue.

2014-11-26staging: r8188eu: Fix scheduling while atomic error introduced in commit ↵Larry Finger3-18/+18
fadbe0cd In commit fadbe0cd5292851608e2e01b91d9295fa287b9fe entitled "staging: rtl8188eu:Remove rtw_zmalloc(), wrapper for kzalloc()", the author failed to note that the original code in the wrapper tested whether the caller could sleep, and set the flags argument to kzalloc() appropriately. After the patch, GFP_KERNEL is used unconditionally. Unfortunately, several of the routines may be entered from an interrupt routine and generate a BUG splat for every such call. Routine rtw_sitesurvey_cmd() is used in the example below: BUG: sleeping function called from invalid context at mm/slub.c:1240 in_atomic(): 1, irqs_disabled(): 0, pid: 756, name: wpa_supplicant INFO: lockdep is turned off.

2014-11-26net-timestamp: make tcp_recvmsg call ipv6_recv_error for AF_INET6 socksWillem de Bruijn4-11/+16
TCP timestamping introduced MSG_ERRQUEUE handling for TCP sockets. If the socket is of family AF_INET6, call ipv6_recv_error instead of ip_recv_error. This change is more complex than a single branch due to the loadable ipv6 module. It reuses a pre-existing indirect function call from ping. The ping code is safe to call, because it is part of the core ipv6 module and always present when AF_INET6 sockets are active.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: Third set of IIO fixes for the 3.18 cycle. Most of these are fairly standard little fixes, a bmc150 and bmg160 patch is to make an ABI change to indicated a specific axis in an event rather than the generic option in the original drivers. As both of these drivers are new in this cycle it would be ideal to push this minor change through even though it isn't strictly a fix. A couple of other 'fixes' change defaults for some settings on these new drivers to more intuitive calues. Looks like some useful feedback has been coming in for this driver since it was applied. * IIO_EVENT_CODE_EXTRACT_DIR bit mask was wrong and has been for a while 0xCF clearly doesn't give a contiguous bitmask. * kxcjk-1013 range setting was failing to mask out the previous value in the register and hence was 'enable only'. * men_z188 device id table wasn't null terminated. * bmg160 and bmc150 both failed to correctly handling an error in mode setting. * bmg160 and bmc150 both had a bug in setting the event direction in the event spec (leads to an attribute name being incorrect) * bmg160 defaulted to an open drain output for the interrupt - as a default this obviously only works with some interrupt chips - hence change the default to push-pull (note this is a new driver so we aren't going to cause any regressions with this change). * bmc150 had an unintuitive default for the rate of change (motion detector) so change it to 0 (new driver so change of default won't cause any regressions).

2014-11-26drm: Decouple EDID parsing from I2C adapterLars-Peter Clausen2-13/+35
The drm_get_edid() function performs direct I2C accesses to read EDID blocks, assuming that the monitor DDC interface is directly connected to the I2C bus. It can't thus be used with HDMI encoders that control the DDC bus and expose EDID blocks through a different interface. Refactor drm_do_get_edid() to take a block read callback function instead of an I2C adapter, and export it for direct use by drivers. As in the general case the DDC bus is accessible by the kernel at the I2C level, drivers must make all reasonable efforts to expose it as an I2C adapter and use drm_get_edid() instead of abusing this function.

2014-11-26drm: rcar-du: Replace drm_encoder with drm_slave_encoderLaurent Pinchart1-3/+4
DRM slave encoders require their associated struct drm_encoder instance to be embedded in a struct drm_slave_encoder. This makes processing encoders regardless of their types needlessly and painfully complex in drivers that use a mix of slave encoders and custom encoders. Such a driver will need to either create drm_slave_encoder instances that fake their embedded encoder instance, or to turn all drm_encoder instances into drm_slave_encoder instances. Between the two evils, one must choose the lesser. Use drm_slave_encoder everywhere. Signed-off-by: Laurent Pinchart <[email protected]>

2014-11-26net/mlx4_core: Limit count field to 24 bits in qp_alloc_resJack Morgenstein1-1/+1
Some VF drivers use the upper byte of "param1" (the qp count field) in mlx4_qp_reserve_range() to pass flags which are used to optimize the range allocation. Under the current code, if any of these flags are set, the 32-bit count field yields a count greater than 2^24, which is out of range, and this VF fails. As these flags represent a "best-effort" allocation hint anyway, they may safely be ignored. Therefore, the PF driver may simply mask out the bits.

2014-11-26kvm: fix kvm_is_mmio_pfn() and rename to kvm_is_reserved_pfn()Ard Biesheuvel4-13/+13
This reverts commit 85c8555ff0 ("KVM: check for !is_zero_pfn() in kvm_is_mmio_pfn()") and renames the function to kvm_is_reserved_pfn. The problem being addressed by the patch above was that some ARM code based the memory mapping attributes of a pfn on the return value of kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should be mapped as device memory. However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin, and the existing non-ARM users were already using it in a way which suggests that its name should probably have been 'kvm_is_reserved_pfn' from the beginning, e.g., whether or not to call get_page/put_page on it etc. This means that returning false for the zero page is a mistake and the patch above should be reverted.

2014-11-26arm64: KVM: Handle traps of ICC_SRE_EL1 as RAZ/WIChristoffer Dall1-0/+9
When running on a system with a GICv3, we currenly don't allow the guest to access the system register interface of the GICv3. We do this by clearing the ICC_SRE_EL2.Enable, which causes all guest accesses to ICC_SRE_EL1 to trap to EL2 and causes all guest accesses to other ICC_ registers to cause an undefined exception in the guest. However, we currently don't handle the trap of guest accesses to ICC_SRE_EL1 and will spill out a warning. The trap just needs to handle the access as RAZ/WI, and a guest that tries to prod this register and set ICC_SRE_EL1.SRE=1, must read back the value (which Linux already does) to see if it succeeded, and will thus observe that ICC_SRE_EL1.SRE was not set.

2014-11-26arm64: KVM: fix unmapping with 48-bit VAsMark Rutland1-1/+2
Currently if using a 48-bit VA, tearing down the hyp page tables (which can happen in the absence of a GICH or GICV resource) results in the rather nasty splat below, evidently becasue we access a table that doesn't actually exist. Commit 38f791a4e499792e (arm64: KVM: Implement 48 VA support for KVM EL2 and Stage-2) added a pgd_none check to __create_hyp_mappings to account for the additional level of tables, but didn't add a corresponding check to unmap_range, and this seems to be the source of the problem. This patch adds the missing pgd_none check, ensuring we don't try to access tables that don't exist.

2014-11-26drm/i915: Cancel vdd off work before suspendVille Syrjälä1-0/+1
Currently we just make sure vdd is off before suspending, but we don't cancel the vdd off work. The work wil not touch vdd if want_panel_vdd==false so in theory this is fine. In the past that was perfectly fine since the vdd off work didn't do anything when want_panel_vdd==false, so even if the work would have been run during system resume before i915 has resumed, nothing would happen. However since pps_lock() will now grab the power domain references before it can check want_panel_vdd, we may end up toggling the power wells on/off already before the driver has resumed. That is not really acceptable, so cancel the vdd off work when suspending the encoder. The problem appeared when pps_lock() was introduced in: commit 773538e86081d146e0020435d614f4b96996c1f9 Author: Ville Syrjälä <[email protected]> Date: Thu Sep 4 14:54:56 2014 +0300 drm/i915: Reset power sequencer pipe tracking when disp2d is off Signed-off-by: Ville Syrjälä <[email protected]> Reviewed-by: Imre Deak <[email protected]> Signed-off-by: Jani Nikula <[email protected]>
2014-11-26ufs: fix NULL dereference when no regulators are definedAkinobu Mita1-0/+6
If no voltage supply regulators are defined for the UFS devices (assumed they are always-on), ufshcd_config_vreg_load() can be called on suspend/resume paths with vreg == NULL as hba->vreg_info.vcc* equal to NULL, and it causes NULL pointer dereference. This fixes it by making ufshcd_config_vreg_{h,l}pm noop when no regulators are defined.

2014-11-26ufs: ensure clk gating work is finished before module unloadingAkinobu Mita1-0/+2
When dynamic clk gating feature is enabled, delayed workqueue machanism is used in order to detect certain period of inactivity. But there is no guarantee that scheduled gating work is completed before module unloading. So it can cause kernel crash by accessing memory after it was freed. Fix it by cancelling clk gating and ungating works and ensure that its execution is finished before module unloading.

Basically, some (radeon) adapters have issues with MSI addresses above 1T (only support 40-bits). We had powerpc specific quirk but it only listed a specific revision of an adapter that we shipped with our machines and didn't properly handle the audio function which some distros enable nowadays. So we made the quirk generic and fixed both the graphic and audio drivers properly to use it. Without that, ppc64 server machines will crash at boot with a radeon adapter.
