The list of dependencies here is phrased as an opt-out, but this is missing a lot of architectures that don't actually support VGA consoles, and some of the entries are stale: - powerpc used to support VGA consoles in the old arch/ppc codebase, but the merged arch/powerpc never did - arm lists footbridge, integrator and netwinder, but netwinder is actually part of footbridge, and integrator does not appear to have an actual VGA hardware, or list it in its ATAG or DT. - mips has a few platforms (malta, sibyte, and sni) that initialize screen_info, on everything else the console is selected but cannot actually work. - csky, hexgagon, loongarch, nios2, riscv and xtensa are not listed in the opt-out table and declare a screen_info to allow building vga_con, but this cannot work because the console is never selected. Replace this with an opt-in table that lists only the platforms that remain. This is effectively x86, plus a couple of historic workstation and server machines that reused parts of the x86 system architecture.

uart_get_baud_rate has input parameters 'min' and 'max' limiting the range of acceptable baud rates from the caller's perspective. If neither current or old termios structures have acceptable baud rate setting and 9600 is not in the min/max range either the function returns 0 and issues a warning. However for a UART that does not support speed of 9600 baud this is expected behavior. Clarify that 0 can be (and always could be) returned from the uart_get_baud_rate. Don't issue a warning in that case.

This reverts commit 45e34c8a, and the two subsequent fixes to it: 3f874c9b ("x86/smp: Don't send INIT to non-present and non-booted CPUs") b1472a60 ("x86/smp: Don't send INIT to boot CPU") because it seems to result in hung machines at shutdown. Particularly some Dell machines, but Thomas says "The rest seems to be Lenovo and Sony with Alderlake/Raptorlake CPUs - at least that's what I could figure out from the various bug reports. I don't know which CPUs the DELL machines have, so I can't say it's a pattern. I agree with the revert for now" Ashok Raj chimes in: "There was a report (probably this same one), and it turns out it was a bug in the BIOS SMI handler. The client BIOS's were waiting for the lowest APICID to be the SMI rendevous master. If this is MeteorLake, the BSP wasn't the one with the lowest APIC and it triped here. The BIOS change is also being pushed to others for assimilation :) Server BIOS's had this correctly for a while now" and it does look likely to be some bad interaction between SMI and the non-BSP cores having put into INIT (and thus unresponsive until reset).

Commit 295525e2 ("virtio_net: merge dma operations when filling mergeable buffers") unmaps the buffer with DMA_ATTR_SKIP_CPU_SYNC when the dma->ref is zero. We do that with DMA_ATTR_SKIP_CPU_SYNC, because we do not want to do the sync for the entire page_frag. But that misses the sync for the current area. This patch does cpu sync regardless of whether the ref is zero or not.

Kernel v6.5 converted overlayfs to new mount api. As an added bonus, it also added a feature to allow appending lowerdirs using lowerdir=:/lower2,lowerdir=::/data3 syntax. This new syntax has raised some concerns regarding escaping of colons. We decided to try and disable this syntax, which hasn't been in the wild for so long and introduce it again in 6.7 using explicit mount options lowerdir+=/lower2,datadir+=/data3.

Before commit b36a5780 ("ovl: modify layer parameter parsing"), spaces and commas in lowerdir mount option value used to be escaped using seq_show_option(). In current upstream, when lowerdir value has a space, it is not escaped in /proc/mounts, e.g.: none /mnt overlay rw,relatime,lowerdir=l l,upperdir=u,workdir=w 0 0 which results in broken output of the mount utility: none on /mnt type overlay (rw,relatime,lowerdir=l) Store the original lowerdir mount options before unescaping and show them using the same escaping used for seq_show_option() in addition to escaping the colon separator character.

Can't be hit without the original patch above, but still good to have it fixed - a couple new device IDs in xpad Xbox driver - another quirk for Goodix driver to deal with stuff vendors put in ACPI tables - a fix for use-after-free on disconnect for powermate driver - a quirk to not initialize PS/2 mouse port on Fujitsu Lifebook E5411 laptop as it makes keyboard not usable and the device uses hid-over-i2c touchpad anyways * tag 'input-for-v6.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: powermate - fix use-after-free in powermate_config_complete Input: xpad - add PXN V900 support Input: synaptics-rmi4 - handle reset delay when using SMBus trsnsport Input: psmouse - fix fast_reconnect function for PS/2 mode Revert "Input: psmouse - add delay when deactivating for SMBus mode" Input: goodix - ensure int GPIO is in input for gpio_count == 1 && gpio_int_idx == 0 case Input: i8042 - add Fujitsu Lifebook E5411 to i8042 quirk table Input: xpad - add HyperX Clutch Gladiate Support

syzbot has found a use-after-free bug [1] in the powermate driver. This happens when the device is disconnected, which leads to a memory free from the powermate_device struct. When an asynchronous control message completes after the kfree and its callback is invoked, the lock does not exist anymore and hence the bug. Use usb_kill_urb() on pm->config to cancel any in-progress requests upon device disconnection.

Touch controllers need some time after receiving reset command for the firmware to finish re-initializing and be ready to respond to commands from the host. The driver already had handling for the post-reset delay for I2C and SPI transports, this change adds the handling to SMBus-connected devices. SMBus devices are peculiar because they implement legacy PS/2 compatibility mode, so reset is actually issued by psmouse driver on the associated serio port, after which the control is passed to the RMI4 driver with SMBus companion device. Note that originally the delay was added to psmouse driver in 92e24e0e ("Input: psmouse - add delay when deactivating for SMBus mode"), but that resulted in an unwanted delay in "fast" reconnect handler for the serio port, so it was decided to revert the patch and have the delay being handled in the RMI4 driver, similar to the other transports.

When the SMBus connection is attempted psmouse_smbus_init() sets the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will fallback to PS/2 mode, replacing the psmouse private data. This can cause issues on resume, since psmouse_smbus_reconnect() expects to find an instance of struct psmouse_smbus_dev in psmouse->private. The issue was uncovered when in 92e24e0e ("Input: psmouse - add delay when deactivating for SMBus mode") psmouse_smbus_reconnect() started attempting to use more of the data structure. The commit was since reverted, not because it was at fault, but because there was found a better way of doing what it was attempting to do. Fix the problem by resetting the fast_reconnect pointer in psmouse structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2 mode is used.
