2021-05-21net/qla3xxx: fix schedule while atomic in ql_sem_spinlockZheyu Ma1-1/+1
When calling the 'ql_sem_spinlock', the driver has already acquired the spin lock, so the driver should not call 'ssleep' in atomic context.

2021-05-21net: encx24j600: fix kernel-doc syntax in file headersAditya Srivastava2-2/+2
The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. The header for drivers/net/ethernet/microchip/encx24j600 files follows this syntax, but the content inside does not comply with kernel-doc. This line was probably not meant for kernel-doc parsing, but is parsed due to the presence of kernel-doc like comment syntax(i.e, '/**'), which causes unexpected warning from kernel-doc. For e.g., running scripts/kernel-doc -none drivers/net/ethernet/microchip/encx24j600_hw.h emits: warning: expecting prototype for h(). Prototype was for _ENCX24J600_HW_H() instead Provide a simple fix by replacing such occurrences with general comment format, i.e. '/*', to prevent kernel-doc from parsing it.

2021-05-20serial: 8250: Add UART_BUG_TXRACE workaround for Aspeed VUARTAndrew Jeffery3-0/+14
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.

2021-05-20thunderbolt: usb4: Fix NVM read buffer bounds and offset issueMathias Nyman1-4/+5
Up to 64 bytes of data can be read from NVM in one go. Read address must be dword aligned. Data is read into a local buffer. If caller asks to read data starting at an unaligned address then full dword is anyway read from NVM into a local buffer. Data is then copied from the local buffer starting at the unaligned offset to the caller buffer. In cases where asked data length + unaligned offset is over 64 bytes we need to make sure we don't read past the 64 bytes in the local buffer when copying to caller buffer, and make sure that we don't skip copying unaligned offset bytes from local buffer anymore after the first round of 64 byte NVM data read.

2021-05-20thunderbolt: dma_port: Fix NVM read buffer bounds and offset issueMathias Nyman1-5/+6
Up to 64 bytes of data can be read from NVM in one go. Read address must be dword aligned. Data is read into a local buffer. If caller asks to read data starting at an unaligned address then full dword is anyway read from NVM into a local buffer. Data is then copied from the local buffer starting at the unaligned offset to the caller buffer. In cases where asked data length + unaligned offset is over 64 bytes we need to make sure we don't read past the 64 bytes in the local buffer when copying to caller buffer, and make sure that we don't skip copying unaligned offset bytes from local buffer anymore after the first round of 64 byte NVM data read.

2021-05-19Revert "i915: fix remap_io_sg to verify the pgprot"Linus Torvalds1-23/+50
This reverts commit b12d691ea5e01db42ccf3b4207e57cb3ce7cfe91. It turns out this is not ready for primetime yet. The intentions are good, but using remap_pfn_range() requires that there is nothing already mapped in the area, and the i915 code seems to very much intentionally remap the same area multiple times. That will then just trigger the BUG_ON(!pte_none(*pte)); in mm/memory.c: remap_pte_range(). There are also reports of mapping type inconsistencies, resulting in warnings and in screen corruption.
