2023-02-22io_uring: rename 'in_idle' to 'in_cancel'Jens Axboe

Commit 0f2cb928a154 ("arm64: consistently pass ESR_ELx to die()") caused all callers to pass the ESR_ELx value to die(). For consistency, this patch also adds esr to die() call of cfi_handler.

2023-02-22arm64: Reset KASAN tag in copy_highpage with HW tags onlyPeter Collingbourne
During page migration, the copy_highpage function is used to copy the page data to the target page. If the source page is a userspace page with MTE tags, the KASAN tag of the target page must have the match-all tag in order to avoid tag check faults during subsequent accesses to the page by the kernel. However, the target page may have been allocated in a number of ways, some of which will use the KASAN allocator and will therefore end up setting the KASAN tag to a non-match-all tag. Therefore, update the target page's KASAN tag to match the source page. We ended up unintentionally fixing this issue as a result of a bad merge conflict resolution between commit e059853d14ca ("arm64: mte: Fix/clarify the PG_mte_tagged semantics") and commit 20794545c146 ("arm64: kasan: Revert "arm64: mte: reset the page tag in page->flags""), which preserved a tag reset for PG_mte_tagged pages which was considered to be unnecessary at the time. Because SW tags KASAN uses separate tag storage, update the code to only reset the tags when HW tags KASAN is enabled.

2023-02-22swiotlb: mark swiotlb_memblock_alloc() as __initRandy Dunlap
swiotlb_memblock_alloc() calls memblock_alloc(), which calls (__init) memblock_alloc_try_nid(). However, swiotlb_membloc_alloc() can be marked as __init since it is only called by swiotlb_init_remap(), which is already marked as __init.

2023-02-22wifi: rtw89: refine FW feature judgement on packet dropZong-Zhe Yang
The newer chips use the newer firmware branches, e.g. v027, v029. And, those firmware branches are supposed to support packet drop when they are just branched out. The initial firmware branch used by each chip is as below. * 8852A: v009 * 8852C: v027 * 8852B: v027 So, only 8852A may use firmware which doesn't support packet drop at runtime. To save trivial positive listing in firmware feature table, we change to reverse judgment. Besides, rtw89_mac_ptk_drop_by_band_and_wait() missed to check firmware feature before calling rtw89_fw_h2c_pkt_drop(). We also fix it.

2023-02-22wifi: rtw89: add RNR support for 6 GHz scanPo-Hao Huang
Since 6 GHz band has around 60 channels and more strict rules for active probing. Reduced neighbor report can be used to reduce the channels we scan and get specific target BSS info to probe for. Declare flag WIPHY_FLAG_SPLIT_SCAN_6GHZ so the scan request could be divided into two portions: legacy bands and 6 GHz bands. So RNR information from legacy bands could later be used when 6 GHz scan. When the scan flag NL80211_SCAN_FLAG_COLOCATED_6GHZ is set, cfg80211 will pass down a reduced channel set which contains PSCs and non-PSC with RNR info received in the 2 GHz/5 GHz band. This reduces the scan duration by allowing us to only scan for channels in which APs are currently operating.

2023-02-22gfs2: jdata writepage fixAndreas Gruenbacher
The ->writepage() and ->writepages() operations are supposed to write entire pages. However, on filesystems with a block size smaller than PAGE_SIZE, __gfs2_jdata_writepage() only adds the first block to the current transaction instead of adding the entire page. Fix that.

2023-02-22backlight: pwm_bl: Don't rely on a disabled PWM emiting inactive stateUwe Kleine-König
Most but not all PWMs drive the PWM pin to its inactive state when disabled. However if there is no enable_gpio and no regulator the PWM must drive the inactive state to actually disable the backlight. So keep the PWM on in this case. Note that to determine if there is a regulator some effort is required because it might happen that there isn't actually one but the regulator core gave us a dummy. (A nice side effect is that this makes the regulator actually optional even on fully constrained systems.) This fixes backlight disabling e.g. on i.MX6 when an inverted PWM is used. Hint for the future: If this change results in a regression, the bug is in the lowlevel PWM driver.

2023-02-22backlight: pwm_bl: Configure pwm only once per backlight toggleUwe Kleine-König
When the function pwm_backlight_update_status() was called with brightness > 0, pwm_get_state() was called twice (once directly and once in compute_duty_cycle). Also pwm_apply_state() was called twice (once in pwm_backlight_power_on() and once directly). Optimize this to do both calls only once. Note that with this affects the order of regulator and PWM setup. It's not expected to have a relevant effect on hardware. The rationale for this is that the regulator (and the GPIO) are reasonable to switch in pwm_backlight_power_on()/pwm_backlight_power_off() but the PWM has nothing to do with power. (The post_pwm_on_delay and pwm_off_delay are still there though.)
