2021-05-20NFS: fix an incorrect limit in filelayout_decode_layout()Dan Carpenter
The "sizeof(struct nfs_fh)" is two bytes too large and could lead to memory corruption. It should be NFS_MAXFHSIZE because that's the size of the ->data[] buffer. I reversed the size of the arguments to put the variable on the left.

2021-05-20xfs: fix deadlock retry tracepoint argumentsDarrick J. Wong
sc->ip is the inode that's being scrubbed, which means that it's not set for scrub types that don't involve inodes. If one of those scrubbers (e.g. inode btrees) returns EDEADLOCK, we'll trip over the null pointer. Fix that by reporting either the file being examined or the file that was used to call scrub.

2021-05-20xfs: retry allocations when locality-based search failsDarrick J. Wong
If a realtime allocation fails because we can't find a sufficiently large free extent satisfying locality rules, relax the locality rules and try again. This reduces the occurrence of short writes to realtime files when the write size is large and the free space is fragmented. This was originally discovered by running generic/186 with the realtime reflink patchset and a 128k cow extent size hint, but the short write symptoms can manifest with a 128k extent size hint and no reflink, so apply the fix now.

2021-05-20serial: 8250: Add UART_BUG_TXRACE workaround for Aspeed VUARTAndrew Jeffery
Aspeed Virtual UARTs directly bridge e.g. the system console UART on the LPC bus to the UART interface on the BMC's internal APB. As such there's no RS-232 signalling involved - the UART interfaces on each bus are directly connected as the producers and consumers of the one set of FIFOs. The APB in the AST2600 generally runs at 100MHz while the LPC bus peaks at 33MHz. The difference in clock speeds exposes a race in the VUART design where a Tx data burst on the APB interface can result in a byte lost on the LPC interface. The symptom is LSR[DR] remains clear on the LPC interface despite data being present in its Rx FIFO, while LSR[THRE] remains clear on the APB interface as the host has not consumed the data the BMC has transmitted. In this state, the UART has stalled and no further data can be transmitted without manual intervention (e.g. resetting the FIFOs, resulting in loss of data). The recommended work-around is to insert a read cycle on the APB interface between writes to THR.

2021-05-20btrfs: zoned: fix parallel compressed writesJohannes Thumshirn
When multiple processes write data to the same block group on a compressed zoned filesystem, the underlying device could report I/O errors and data corruption is possible. This happens because on a zoned file system, compressed data writes where sent to the device via a REQ_OP_WRITE instead of a REQ_OP_ZONE_APPEND operation. But with REQ_OP_WRITE and parallel submission it cannot be guaranteed that the data is always submitted aligned to the underlying zone's write pointer. The change to using REQ_OP_ZONE_APPEND instead of REQ_OP_WRITE on a zoned filesystem is non intrusive on a regular file system or when submitting to a conventional zone on a zoned filesystem, as it is guarded by btrfs_use_zone_append.

2021-05-19drm/i915/adl_p: Tx escape clock with DSIMika Kahola
Today when the DSI controller is paired with the Combo-PHY it uses the high-speed (HS) Word clock for its low power (LP) transmit PPI communication to the DPHY. The interface signaling only changes state at an Escape clock frequency (i.e. its effectively running on a virtual Tx Escape clock that is controlled by counters w/in the controller), but all the interface flops are running off the HS clock. This has the following drawbacks: * It is a deviation from the PPI spec which assumes signaling is running on a physical Escape clock * The PV timings are over constrained (HS timed to 312.5MHz vs. an Escape clock of 20MHz max) This feature is proposing to change the LP Tx communication between the controller and the DPHY from a virtual Tx Escape clock to a physical clock. To do this we need to program two "M" divisors. One for the usual DSI_ESC_CLK_DIV and DPHY_ESC_CLK_DIV register and one for MIPIO_DWORD8. For DSI_ESC_CLK_DIV and DPHY_ESC_CLK_DIV registers the "M" is calculated as following Nt = ceil(f_link/160) (theoretical word clock) Nact = max[3, Nt + (Nt + 1)%2] (actual word clock) M = Nact * 8 For MIPIO_DWORD8 register, the divisor "M" is calculated as following M = (Nact - 1)/2 BSpec: 55171 Cc: Vandita Kulkarni <vandita.kulkarni@intel.com> Signed-off-by: Mika Kahola <mika.kahola@intel.com> Signed-off-by: Clinton Taylor <Clinton.A.Taylor@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Vandita Kulkarni <vandita.kulkarni@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210519000625.3184321-11-lucas.demarchi@intel.com

2021-05-19drm/i915: Introduce MBUS relative dbuf offsetsVille Syrjälä
The dbuf slices are going to be split across several MBUS units. The actual dbuf programming will use offsets relative to the MBUS unit. To accommodate that we shall store the MBUS relative offsets into the dbuf_state->ddb[] and crtc_state->plane_ddb*[]. For crtc_state->wm.skl.ddb however we want to stick to global offsets as we use this to sanity check that the ddb allocations don't overlap between pipes.

2021-05-20powerpc: Fix early setup to make early_ioremap() workAlexey Kardashevskiy
The immediate problem is that after commit 0bd3f9e953bd ("powerpc/legacy_serial: Use early_ioremap()") the kernel silently reboots on some systems. The reason is that early_ioremap() returns broken addresses as it uses slot_virt[] array which initialized with offsets from FIXADDR_TOP == IOREMAP_END+FIXADDR_SIZE == KERN_IO_END - FIXADDR_SIZ + FIXADDR_SIZE == __kernel_io_end which is 0 when early_ioremap_setup() is called. __kernel_io_end is initialized little bit later in early_init_mmu(). This fixes the initialization by swapping early_ioremap_setup() and early_init_mmu().
