Commit 3840ed95 ("tty: goldfish: Implement support for kernel 'earlycon' parameter") breaks an allmodconfig config on x86: | LD vmlinux.o | MODPOST vmlinux.o |drivers/tty/serial/earlycon.o: In function `parse_options': |drivers/tty/serial/earlycon.c:97: undefined reference to `uart_parse_earlycon' |Makefile:1005: recipe for target 'vmlinux' failed earlycon.c::parse_options() invokes uart_parse_earlycon() from serial_core.c which is compiled=m because GOLDFISH_TTY itself (and most others) are =m. To avoid that, I'm adding the _CONSOLE config option which is selected if the GOLDFISH module itself is =y since it doesn't need the early bits for the =m case (other drivers do the same dance). The alternative would be to move uart_parse_earlycon() from serial_core.c to earlycon.c (we don't have that many users of that function).

The driver may sleep under a spinlock. The function call paths are: isicom_activate (acquire the spinlock) isicom_setup_board drop_dtr_rts WaitTillCardIsFree msleep --> may sleep isicom_set_termios isicom_config_port drop_dtr WaitTillCardIsFree msleep --> may sleep isicom_tiocmset drop_dtr WaitTillCardIsFree msleep --> may sleep Though "in_atomic" is used to check atomic context, but it is not recommended to use in driver code (see include/linux/preempt.h). To fix it, only using mdelay instead. This bug is found by my static analysis tool(DSAC) and checked by my code review.

On most Renesas ARM platforms, the SCIF serial ports can be used with DMA, so most users will want DMA support to be enabled. On SuperH platforms, SCI(F) serial ports cannot be used with DMA yet (see also commit 219fb0c1 ("serial: sh-sci: Remove the platform data dma slave rx/tx channel IDs")), so users will want it disabled to reduce kernel size. Hence follow the above rationale to configure the default, unless CONFIG_EXPERT is enabled.

Renesas H8/300 and ARM platforms use DT and support earlycon, so most users want earlycon support to be enabled. On SuperH platforms, earlycon is not yet supported.

Auto-configure the maximum number of serial ports based on how many can be present on the architecture: - 3 on H8/300, - 10 on SuperH, - 18 on Reneas ARM.

Christian Borntraeger authored
Using "make kvmconfig" results in a potentially unusable linux image on s390. The reason is that both the (default on s390) sclp consoles as well as the 8250 console register a ttyS<x> as console. Since there will be no 8250 on s390 let's fence 8250. This will ensure that there is always a working sclp console.

sign_extend32 counts the sign bit parameter from 0, not from 1. So we have to use "11" for 12th bit, not "12". This mistake means we have not allowed negative op and cmp args since commit 30d6e0a4 ("futex: Remove duplicated code and fix undefined behaviour") till now.

Most important here are the MIC and IVC fixes for iwlwifi to unbreak 9000 series. iwlwifi * fix rate-scaling to not start lowest possible rate * fix the TX queue hang detection for AP/GO modes * fix the TX queue hang timeout in monitor interfaces * fix packet injection * remove a wrong error message when dumping PCI registers * fix race condition with RF-kill * tell mac80211 when the MIC has been stripped (9000 series) * tell mac80211 when the IVC has been stripped (9000 series) * add 2 new PCI IDs, one for 9000 and one for 22000 * fix a queue hang due during a P2P Remain-on-Channel operation brcmfmac * fix a race which sometimes caused a crash during sdio unbind * fix a kernel-doc related build error ==================== Signed-off-by: David S.

The macro used to access or set an RSS table entry was using an offset of 8, while it should use an offset of 0. This lead to wrongly configure the RSS table, not accessing the right entries.

RACK skips an ACK unless it advances the most recently delivered TX timestamp (rack.mstamp). Since RACK also uses the most recent RTT to decide if a packet is lost, RACK should still run the loss detection whenever the most recent RTT changes. For example, an ACK that does not advance the timestamp but triggers the cwnd undo due to reordering, would then use the most recent (higher) RTT measurement to detect further losses.

When sender detects spurious retransmission, all packets marked lost are remarked to be in-flight. However some may be considered lost based on its timestamps in RACK. This patch forces RACK to re-evaluate, which may be skipped previously if the ACK does not advance RACK timestamp.

RACK does not test the loss recovery state correctly to compute the reordering window. It assumes if lost_out is zero then TCP is not in loss recovery. But it can be zero during recovery before calling tcp_rack_detect_loss(): when an ACK acknowledges all packets marked lost before receiving this ACK, but has not yet to discover new ones by tcp_rack_detect_loss(). The fix is to simply test the congestion state directly.
