2022-07-08OPP: Remove dev_pm_opp_find_freq_ceil_by_volt()Viresh Kumar1-8/+0
This was added few years back, but the code that was supposed to use it never got merged. Remove the unused helper. Tested-by: Dmitry Osipenko <dmitry.osipenko@collabora.com> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
2022-07-08OPP: Remove custom OPP helper supportViresh Kumar1-51/+0
The only user of the custom helper is migrated to use dev_pm_opp_set_config_regulators() interface. Remove the now unused custom OPP helper support. This cleans up _set_opp() and leaves a single code path to be used by all users. Tested-by: Dmitry Osipenko <dmitry.osipenko@collabora.com> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
2022-07-08OPP: Add dev_pm_opp_get_supplies()Viresh Kumar1-0/+7
We already have an API for getting voltage information for a single regulator, dev_pm_opp_get_voltage(), but there is nothing available for multiple regulator case. This patch adds a new API, dev_pm_opp_get_supplies(), to get all information related to the supplies for an OPP.

2022-07-08OPP: Add support for config_regulators() helperViresh Kumar1-0/+22
Extend the dev_pm_opp_set_config() interface to allow adding config_regulators() helpers. This helper will be called to set the voltages of the regulators from the regular path in _set_opp(), while we are trying to change the OPP. This will eventually replace the custom set_opp() helper.

2022-07-08OPP: Add dev_pm_opp_set_config() and friendsViresh Kumar1-0/+42
The OPP core already have few configuration specific APIs and it is getting complex or messy for both the OPP core and its users. Lets introduce a new set of API which will be used for all kind of different configurations, and shall eventually be used by all the existing ones. The new API, returns a unique token instead of a pointer to the OPP table, which allows the OPP core to drop the resources selectively later on.

2022-07-07vfio/ccw: Remove UUID from s390 debug logMichael Kawano1-5/+0
As vfio-ccw devices are created/destroyed, the uuid of the associated mdevs that are recorded in $S390DBF/vfio_ccw_msg/sprintf get lost. This is because a pointer to the UUID is stored instead of the UUID itself, and that memory may have been repurposed if/when the logs are examined. The result is usually garbage UUID data in the logs, though there is an outside chance of an oops happening here. Simply remove the UUID from the traces, as the subchannel number will provide useful configuration information for problem determination, and is stored directly into the log instead of a pointer. As we were the only consumer of mdev_uuid(), remove that too.

Commit c275c5c6d50a ("kasan: disable freed user page poisoning with HW tags") added __GFP_SKIP_KASAN_POISON to GFP_HIGHUSER_MOVABLE. A similar argument can be made about unpoisoning, so also add __GFP_SKIP_KASAN_UNPOISON to user pages. To ensure the user page is still accessible via page_address() without a kasan fault, reset the page->flags tag. With the above changes, there is no need for the arm64 tag_clear_highpage() to reset the page->flags tag.

2022-07-07fbcon: Prevent that screen size is smaller than font sizeHelge Deller1-0/+4
We need to prevent that users configure a screen size which is smaller than the currently selected font size. Otherwise rendering chars on the screen will access memory outside the graphics memory region. This patch adds a new function fbcon_modechange_possible() which implements this check and which later may be extended with other checks if necessary. The new function is called from the FBIOPUT_VSCREENINFO ioctl handler in fbmem.c, which will return -EINVAL if userspace asked for a too small screen size.

2022-07-07genirq: Provide an IRQ affinity mask in non-SMP configsSamuel Holland1-0/+8
IRQ affinity masks are not allocated in uniprocessor configurations. This requires special case non-SMP code in drivers for irqchips which have per-CPU enable or mask registers. Since IRQ affinity is always the same in a uniprocessor configuration, we can provide a correct affinity mask without allocating one per IRQ. By returning a real cpumask from irq_data_get_affinity_mask even when SMP is disabled, irqchip drivers which iterate over that mask will automatically do the right thing.

2022-07-07genirq: Add and use an irq_data_update_affinity helperSamuel Holland1-0/+6
Some architectures and irqchip drivers modify the cpumask returned by irq_data_get_affinity_mask, usually by copying in to it. This is problematic for uniprocessor configurations, where the affinity mask should be constant, as it is known at compile time. Add and use a setter for the affinity mask, following the pattern of irq_data_update_effective_affinity. This allows the getter function to return a const cpumask pointer.

When enabled, all taken branch addresses are output, even if the branch was because of a direct branch instruction. This enables reconstruction of the program flow without having access to the memory image of the code being executed. Use bit 8 for the config option which would be the correct bit for programming ETMv3. Although branch broadcast can't be enabled on ETMv3 because it's not in the define ETM3X_SUPPORTED_OPTIONS, using the correct bit might help prevent future collisions or allow it to be enabled if needed.

2022-07-06blk-mq: Drop blk_mq_ops.timeout 'reserved' argJohn Garry1-1/+1
With new API blk_mq_is_reserved_rq() we can tell if a request is from the reserved pool, so stop passing 'reserved' arg. There is actually only a single user of that arg for all the callback implementations, which can use blk_mq_is_reserved_rq() instead. This will also allow us to stop passing the same 'reserved' around the blk-mq iter functions next.
