2020-09-10f2fs: support zone capacity less than zone sizeAravind Ramesh1-0/+15
NVMe Zoned Namespace devices can have zone-capacity less than zone-size. Zone-capacity indicates the maximum number of sectors that are usable in a zone beginning from the first sector of the zone. This makes the sectors sectors after the zone-capacity till zone-size to be unusable. This patch set tracks zone-size and zone-capacity in zoned devices and calculate the usable blocks per segment and usable segments per section. If zone-capacity is less than zone-size mark only those segments which start before zone-capacity as free segments. All segments at and beyond zone-capacity are treated as permanently used segments. In cases where zone-capacity does not align with segment size the last segment will start before zone-capacity and end beyond the zone-capacity of the zone. For such spanning segments only sectors within the zone-capacity are used. During writes and GC manage the usable segments in a section and usable blocks per segment. Segments which are beyond zone-capacity are never allocated, and do not need to be garbage collected, only the segments which are before zone-capacity needs to garbage collected. For spanning segments based on the number of usable blocks in that segment, write to blocks only up to zone-capacity. Zone-capacity is device specific and cannot be configured by the user. Since NVMe ZNS device zones are sequentially write only, a block device with conventional zones or any normal block device is needed along with the ZNS device for the metadata operations of F2fs. A typical nvme-cli output of a zoned device shows zone start and capacity and write pointer as below: SLBA: 0x0 WP: 0x0 Cap: 0x18800 State: EMPTY Type: SEQWRITE_REQ SLBA: 0x20000 WP: 0x20000 Cap: 0x18800 State: EMPTY Type: SEQWRITE_REQ SLBA: 0x40000 WP: 0x40000 Cap: 0x18800 State: EMPTY Type: SEQWRITE_REQ Here zone size is 64MB, capacity is 49MB, WP is at zone start as the zones are in EMPTY state. For each zone, only zone start + 49MB is usable area, any lba/sector after 49MB cannot be read or written to, the drive will fail any attempts to read/write. So, the second zone starts at 64MB and is usable till 113MB (64 + 49) and the range between 113 and 128MB is again unusable. The next zone starts at 128MB, and so on.

Commit 0c2a3913d6f5 ("x86/fpu: Parse clearcpuid= as early XSAVE argument") changed clearcpuid parsing from __setup() to cmdline_find_option(). While the __setup() function would have been called for each clearcpuid= parameter on the command line, cmdline_find_option() will only return the last one, so the change effectively made it impossible to disable more than one bit. Allow a comma-separated list of bit numbers as the argument for clearcpuid to allow multiple bits to be disabled again. Log the bits being disabled for informational purposes. Also fix the check on the return value of cmdline_find_option(). It returns -1 when the option is not found, so testing as a boolean is incorrect.

2020-09-10seqlock: Introduce seqcount_latch_tAhmed S. Darwish1-0/+18
Latch sequence counters are a multiversion concurrency control mechanism where the seqcount_t counter even/odd value is used to switch between two copies of protected data. This allows the seqcount_t read path to safely interrupt its write side critical section (e.g. from NMIs). Initially, latch sequence counters were implemented as a single write function above plain seqcount_t: raw_write_seqcount_latch(). The read side was expected to use plain seqcount_t raw_read_seqcount(). A specialized latch read function, raw_read_seqcount_latch(), was later added. It became the standardized way for latch read paths. Due to the dependent load, it has one read memory barrier less than the plain seqcount_t raw_read_seqcount() API. Only raw_write_seqcount_latch() and raw_read_seqcount_latch() should be used with latch sequence counters. Having *unique* read and write path APIs means that latch sequence counters are actually a data type of their own -- just inappropriately overloading plain seqcount_t. Introduce seqcount_latch_t. This adds type-safety and ensures that only the correct latch-safe APIs are to be used. Not to break bisection, let the latch APIs also accept plain seqcount_t or seqcount_raw_spinlock_t. After converting all call sites to seqcount_latch_t, only that new data type will be allowed.

A new bus type "dfl" is introduced for private features which are not initialized by DFL feature drivers (dfl-fme & dfl-afu drivers). So these private features could be handled by separate driver modules. DFL feature drivers (dfl-fme, dfl-port) will create DFL devices on enumeration. DFL drivers could be registered on this bus to match these DFL devices. They are matched by dfl type & feature_id.

2020-09-10fsi: aspeed: Support CFAM reset GPIOJoel Stanley1-0/+8
Systems have a line for restting the remote CFAM. This is not part of the FSI master, but is associated with it, so it makes sense to include it in the master driver. This exposes a sysfs interface to reset the cfam, abstracting away the direction and polarity of the GPIO, as well as the timing of the reset pulse. Userspace will be blocked until the reset pulse is finished. The reset is hard coded to be in the range of (900, 1000) us. It was observed with a scope to regularly be just over 1ms. If the device tree property is not preset the driver will silently continue.

2020-09-09dt-bindings: spi: Fix spi-bcm-qspi compatible orderingFlorian Fainelli1-8/+8
The binding is currently incorrectly defining the compatible strings from least specifice to most specific instead of the converse. Re-order them from most specific (left) to least specific (right) and fix the examples as well.

2020-09-09dt-bindings: hwlock: omap: Convert binding to YAMLSuman Anna2-41/+76
Convert the current OMAP hwspinlock binding from text format to YAML format/DT schema, and delete the legacy text binding file. The new YAML binding conversion is a slightly updated version compared to the original. The legacy "ti,hwmods" property is now obsolete and is dropped altogether, and the K3 example is updated to showcase the actual dts node usage.

2020-09-09docs: ubifs-authentication: Add a top-level headingJonathan Neuschäfer1-2/+4
This prevents the chapter headings from showing up in the table of contents in filesystems/index.html. Note that I didn't pick "UBIFS Authentication" as the document title, because there is a chapter of the same name, and Sphinx complains about multiple headings with the same name: /.../Documentation/filesystems/ubifs-authentication.rst:207: WARNING: duplicate label filesystems/ubifs-authentication:ubifs authentication, other instance in /.../Documentation/filesystems/ubifs-authentication.rst Remove the :orphan: tag, as the document has been included into the toctree.
