2022-11-28clocksource: hyper-v: Add TSC page support for root partitionStanislav Kinsburskiy
Microsoft Hypervisor root partition has to map the TSC page specified by the hypervisor, instead of providing the page to the hypervisor like it's done in the guest partitions. However, it's too early to map the page when the clock is initialized, so, the actual mapping is happening later. Signed-off-by: Stanislav Kinsburskiy <stanislav.kinsburskiy@gmail.com> CC: "K. Y.

2022-11-28clocksource: hyper-v: Use TSC PFN getter to map vvar pageStanislav Kinsburskiy
Instead of converting the virtual address to physical directly. This is a precursor patch for the upcoming support for TSC page mapping into Microsoft Hypervisor root partition, where TSC PFN will be defined by the hypervisor and thus can't be obtained by linear translation of the physical address.

2022-11-28video: hyperv_fb: Avoid taking busy spinlock on panic pathGuilherme G. Piccoli
The Hyper-V framebuffer code registers a panic notifier in order to try updating its fbdev if the kernel crashed. The notifier callback is straightforward, but it calls the vmbus_sendpacket() routine eventually, and such function takes a spinlock for the ring buffer operations. Panic path runs in atomic context, with local interrupts and preemption disabled, and all secondary CPUs shutdown. That said, taking a spinlock might cause a lockup if a secondary CPU was disabled with such lock taken. Fix it here by checking if the ring buffer spinlock is busy on Hyper-V framebuffer panic notifier; if so, bail-out avoiding the potential lockup scenario.

2022-11-27NFS: Clear the file access cache upon loginTrond Myklebust
POSIX typically only refreshes the user's supplementary group information upon login. Since NFS servers may often refresh their concept of the user supplementary group membership at their own cadence, it is possible for the NFS client's access cache to become stale due to the user's group membership changing on the server after the user has already logged in on the client. While it is reasonable to expect that such group membership changes are rare, and that we do not want to optimise the cache to accommodate them, it is also not unreasonable for the user to expect that if they log out and log back in again, that the staleness would clear up.

2022-11-27mm, slab: ignore SLAB_RECLAIM_ACCOUNT with CONFIG_SLUB_TINYVlastimil Babka
SLAB_RECLAIM_ACCOUNT caches allocate their slab pages with __GFP_RECLAIMABLE and can help against fragmentation by grouping pages by mobility, but on tiny systems mobility grouping is likely disabled anyway and ignoring SLAB_RECLAIM_ACCOUNT might instead lead to merging of caches that are made incompatible just by the flag. Thus with CONFIG_SLUB_TINY, make SLAB_RECLAIM_ACCOUNT ineffective.

Currently SLUB enables its sysfs support depending unconditionally on the general CONFIG_SYSFS setting. To reduce the configuration combination space, make CONFIG_SLUB_TINY disable SLUB's sysfs support by reusing the existing SLAB_SUPPORTS_SYSFS define.

2022-11-27mm, slab: ignore hardened usercopy parameters when disabledVlastimil Babka
With CONFIG_HARDENED_USERCOPY not enabled, there are no __check_heap_object() checks happening that would use the struct kmem_cache useroffset and usersize fields. Yet the fields are still initialized, preventing merging of otherwise compatible caches. Also the fields contribute to struct kmem_cache size unnecessarily when unused. Thus #ifdef them out completely when CONFIG_HARDENED_USERCOPY is disabled. In kmem_dump_obj() print object_size instead of usersize, as that's actually the intention. In a quick virtme boot test, this has reduced the number of caches in /proc/slabinfo from 131 to 111.

2022-11-26scsi: sd: Use 16-byte SYNCHRONIZE CACHE on ZBC devicesShin'ichiro Kawasaki
ZBC Zoned Block Commands specification mandates SYNCHRONIZE CACHE(16) for host-managed zoned block devices, but does not mandate SYNCHRONIZE CACHE(10). Call SYNCHRONIZE CACHE(16) in place of SYNCHRONIZE CACHE(10) to ensure that the command is always supported. For this purpose, add use_16_for_sync flag to struct scsi_device in same manner as use_16_for_rw flag. To be precise, ZBC does not mandate SYNCHRONIZE CACHE(16) for host-aware zoned block devices. However, modern devices should support 16-byte commands. Hence, call SYNCHRONIZE CACHE (16) on both types of ZBC devices, host-aware and host-managed. Of note is that READ(16) and WRITE(16) have same story and they are already called for both types of ZBC devices. Another note is that this patch depends on the fix commit ea045fd344cb ("ata: libata-scsi: fix SYNCHRONIZE CACHE (16) command failure").

2022-11-25misc: fastrpc: Add support for audiopdAbel Vesa
In order to be able to start the adsp listener for audiopd using adsprpcd, we need to add the corresponding ioctl for creating a static process. On that ioctl call we need to allocate the heap. Allocating the heap needs to be happening only once and needs to be kept between different device open calls, so attach it to the channel context to make sure that remains until the RPMSG driver is removed. Then, if there are any VMIDs associated with the static ADSP process, do a call to SCM to assign it. And then, send all the necessary info related to heap to the DSP.

2022-11-25io_uring: allow defer completion for aux posted cqesDylan Yudaken
Multishot ops cannot use the compl_reqs list as the request must stay in the poll list, but that means they need to run each completion without benefiting from batching. Here introduce batching infrastructure for only small (ie 16 byte) CQEs. This restriction is ok because there are no use cases posting 32 byte CQEs. In the ring keep a batch of up to 16 posted results, and flush in the same way as compl_reqs. 16 was chosen through experimentation on a microbenchmark ([1]), as well as trying not to increase the size of the ring too much. This increases the size to 1472 bytes from 1216.

2022-11-25media: dvb-core: Enhance shared multi-frontend supportRobert Schlabbach
Drivers for devices with multiple frontends which cannot be used concurrently due to hardware limitations which enforce that restriction by setting the mfe_shared field to 1 exhibit rather unfriendly behavior towards applications: The unavailable frontend devices cannot be opened at all, not even for read-only access to query information. Even worse, any open call is blocked for 5 seconds by default. Allow drivers for such devices to behave like regular busy frontend devices instead, i.e. still allowing concurrent read access to the unavailable frontend and denying concurrent write access with -EBUSY without delay. This patch does not alter the behavior of any existing driver to avoid regressions. Driver developers who wish to take advantage of this must ensure their driver can handle all read-only accesses to the unavailable frontend, and indicate the capability by setting the mfe_shared field to 2 instead of 1. Add a check to dvb-usb-init.c when automatically setting the mfe_shared field that when a driver has already set the field to 2, it is not overwritten. Document the additional capability in the code comment about mfe_shared.

2022-11-25media: dvb: add DVB-C2 and DVB-S2X parameter valuesRobert Schlabbach
Extend the DVB frontend parameter enums with additional values specified by the DVB-C2 (ETSI EN 302 769) and DVB-S2X (ETSI EN 302 307-2) standards to be ready for frontend drivers for such receivers. While most parameters will be "read-only" due to being autodetected by the receiver and only being reported back for informational purposes, the addition of SYS_DVBC2 to the delivery systems enum is required, because there are DVB-C2 capable receivers which are not capable of DVB-C/C2 autodetection and thus need this enum value to be explicitly instructed to search for a DVB-C2 signal. As for DVB-S2X, as that is an extension to DVB-S2, the same delivery system enum as for DVB-S2 can be used. Add the additional enum values and comments to the documentation.

2022-11-25clk: imx8mn: rename vpu_pll to m7_alt_pllDario Binacchi
The IMX8MN platform does not have any video processing unit (VPU), and indeed in the reference manual (document IMX8MNRM Rev 2, 07/2022) there is no occurrence of its pll. From an analysis of the code and the RM itself, I think vpu pll is used instead of m7 alternate pll, probably for copy and paste of code taken from modules of similar architectures. As an example for all, if we consider the second row of the "Clock Root" table of chapter 5 (Clocks and Power Management) of the RM: Clock Root offset Source Select (CCM_TARGET_ROOTn[MUX]) ... ... ... ARM_M7_CLK_ROOT 0x8080 000 - 24M_REF_CLK 001 - SYSTEM_PLL2_DIV5 010 - SYSTEM_PLL2_DIV4 011 - M7_ALT_PLL_CLK 100 - SYSTEM_PLL1_CLK 101 - AUDIO_PLL1_CLK 110 - VIDEO_PLL_CLK 111 - SYSTEM_PLL3_CLK ... ... ... but in the source code, the imx8mn_m7_sels clocks list contains vpu_pll for the source select bits 011b. So, let's rename "vpu_pll" to "m7_alt_pll" to be consistent with the RM. The IMX8MN_VPU_* constants have not been removed to ensure backward compatibility of the patch.
