2021-06-24Merge branch 'for-next/mm' into for-next/coreWill Deacon
Lots of cleanup to our various page-table definitions, but also some non-critical fixes and removal of some unnecessary memory types. The most interesting change here is the reduction of ARCH_DMA_MINALIGN back to 64 bytes, since we're not aware of any machines that need a higher value with the way the code is structured (only needed for non-coherent DMA). * for-next/mm: arm64: tlb: fix the TTL value of tlb_get_level arm64/mm: Rename ARM64_SWAPPER_USES_SECTION_MAPS arm64: head: fix code comments in set_cpu_boot_mode_flag arm64: mm: drop unused __pa(__idmap_text_start) arm64: mm: fix the count comments in compute_indices arm64/mm: Fix ttbr0 values stored in struct thread_info for software-pan arm64: mm: Pass original fault address to handle_mm_fault() arm64/mm: Drop SECTION_[SHIFT|SIZE|MASK] arm64/mm: Use CONT_PMD_SHIFT for ARM64_MEMSTART_SHIFT arm64/mm: Drop SWAPPER_INIT_MAP_SIZE arm64: mm: decode xFSC in mem_abort_decode() arm64: mm: Add is_el1_data_abort() helper arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES) arm64: mm: Remove unused support for Normal-WT memory type arm64: acpi: Map EFI_MEMORY_WT memory as Normal-NC arm64: mm: Remove unused support for Device-GRE memory type arm64: mm: Use better bitmap_zalloc() arm64/mm: Make vmemmap_free() available only with CONFIG_MEMORY_HOTPLUG arm64/mm: Remove [PUD|PMD]_TABLE_BIT from [pud|pmd]_bad() arm64/mm: Validate CONFIG_PGTABLE_LEVELS
2021-06-24Merge branch 'for-next/misc' into for-next/coreWill Deacon
Reduce loglevel of useless print during CPU offlining. * for-next/misc: arm64: smp: Bump debugging information print down to KERN_DEBUG
2021-06-24Merge branch 'for-next/kasan' into for-next/coreWill Deacon
Optimise out-of-line KASAN checking when using software tagging. * for-next/kasan: kasan: arm64: support specialized outlined tag mismatch checks
2021-06-24Merge branch 'for-next/insn' into for-next/coreWill Deacon
Refactoring of our instruction decoding routines and addition of some missing encodings. * for-next/insn: arm64: insn: avoid circular include dependency arm64: insn: move AARCH64_INSN_SIZE into <asm/insn.h> arm64: insn: decouple patching from insn code arm64: insn: Add load/store decoding helpers arm64: insn: Add some opcodes to instruction decoder arm64: insn: Add barrier encodings arm64: insn: Add SVE instruction class arm64: Move instruction encoder/decoder under lib/ arm64: Move aarch32 condition check functions arm64: Move patching utilities out of instruction encoding/decoding
2021-06-24Merge branch 'for-next/entry' into for-next/coreWill Deacon
The never-ending entry.S refactoring continues, putting us in a much better place wrt compiler instrumentation whilst moving more of the code into C. * for-next/entry: arm64: idle: don't instrument idle code with KCOV arm64: entry: don't instrument entry code with KCOV arm64: entry: make NMI entry/exit functions static arm64: entry: split SDEI entry arm64: entry: split bad stack entry arm64: entry: fold el1_inv() into el1h_64_sync_handler() arm64: entry: handle all vectors with C arm64: entry: template the entry asm functions arm64: entry: improve bad_mode() arm64: entry: move bad_mode() to entry-common.c arm64: entry: consolidate EL1 exception returns arm64: entry: organise entry vectors consistently arm64: entry: organise entry handlers consistently arm64: entry: convert IRQ+FIQ handlers to C arm64: entry: add a call_on_irq_stack helper arm64: entry: move NMI preempt logic to C arm64: entry: move arm64_preempt_schedule_irq to entry-common.c arm64: entry: convert SError handlers to C arm64: entry: unmask IRQ+FIQ after EL0 handling arm64: remove redundant local_daif_mask() in bad_mode()

2021-06-24serial: 8250: 8250_omap: Fix possible interrupt storm on K3 SoCsVignesh Raghavendra
On K3 family of SoCs (which includes AM654 SoC), it is observed that RX TIMEOUT is signalled after RX FIFO has been drained, in which case a dummy read of RX FIFO is required to clear RX TIMEOUT condition. Otherwise, this would lead to an interrupt storm. Fix this by introducing UART_RX_TIMEOUT_QUIRK flag and doing a dummy read in IRQ handler when RX TIMEOUT is reported with no data in RX FIFO.

Fail the usb interface initialization if dev_alloc_name returns an error. Other wlan drivers like natsemi or atmel use the same error handling.

2021-06-24staging: rtl8188eu: fix usb_submit_urb error handlingMartin Kaiser
usb_read_port prepares a bulk in urb and calls usb_submit_urb to pass the usb to the usb core. It seems wrong that usb_read_port returns success to its caller if usb_submit_urb failed with -EPERM. According to drivers/usb/core/urb.c, usb_submit_urb returns -EPERM when an urb is resubmitted after being cancelled by usb_kill_urb etc. The only caller who checks the return value of usb_read_port is rtw_hal_inirp_init. This function submits the bulk in urbs for the first time after the netdevice is opened. We'll not receive -EPERM from usb_submit_urb in this case. The urbs are resubmitted by read_port_complete, which does not check for errors from usb_read_port. This driver may kill pending bulk in urbs when the netdevice is closed when the driver is unloaded or the system goes to sleep. I don't think that this will interrupt an ongoing netdev open.
