2023-01-13Revert "fbcon: don't lose the console font across generic->chip driver switch"Thomas Zimmermann
This reverts commit ae1287865f5361fa138d4d3b1b6277908b54eac9. Always free the console font when deinitializing the framebuffer console. Subsequent framebuffer consoles will then use the default font. Rely on userspace to load any user-configured font for these consoles. Commit ae1287865f53 ("fbcon: don't lose the console font across generic->chip driver switch") was introduced to work around losing the font during graphics-device handover. [1][2] It kept a dangling pointer with the font data between loading the two consoles, which is fairly adventurous hack. It also never covered cases when the other consoles, such as VGA text mode, where involved. The problem has meanwhile been solved in userspace. Systemd comes with a udev rule that re-installs the configured font when a console comes up. [3] So the kernel workaround can be removed. This also removes one of the two special cases triggered by setting FBINFO_MISC_FIRMWARE in an fbdev driver. Tested during device handover from efifb and simpledrm to radeon. Udev reloads the configured console font for the new driver's terminal.

2023-01-13platform/x86: thinkpad_acpi: Fix profile mode display in AMT modeMark Pearson
Recently AMT mode was enabled (somewhat unexpectedly) on the Lenovo Z13 platform. The FW is advertising it is available and the driver tries to use it - unfortunately it reports the profile mode incorrectly. Note, there is also some extra work needed to enable the dynamic aspect of AMT support that I will be following up with; but more testing is needed first. This patch just fixes things so the profiles are reported correctly.

Remove nouveau's support for legacy contexts and buffers. It was required by libdrm earlier than 2.4.33, released in March 2012. A previous attempt in 2013 to remove the functionality [1] had to be reverted [2] as there were still users left. Libdrm 2.4.33 is now almost 11 years old and it is time for userspace to move on. With the nouveau code gone, we can also remove the driver-feature bit DRIVER_KMS_LEGACY_CONTEXT.

There is difference in the TX Flow Control registers (TFCR) between the revisions of the hardware. The older revisions of hardware used to have single register per queue. Whereas, the newer revision of hardware (from ver 30H onwards) have one register per priority. Update the driver to use the TFCR based on the reported version of the hardware.

2023-01-12bpf: hash map, avoid deadlock with suitable hash maskTonghao Zhang
The deadlock still may occur while accessed in NMI and non-NMI context. Because in NMI, we still may access the same bucket but with different map_locked index. For example, on the same CPU, .max_entries = 2, we update the hash map, with key = 4, while running bpf prog in NMI nmi_handle(), to update hash map with key = 20, so it will have the same bucket index but have different map_locked index. To fix this issue, using min mask to hash again.

2023-01-12drm/i915/pxp: Use drm_dbg if arb session failed due to fw versionAlan Previn
If PXP arb-session is being attempted on older hardware SKUs or on hardware with older, unsupported, firmware versions, then don't report the failure with a drm_error. Instead, look specifically for the API-version error reply and drm_dbg that reply. In this case, the user-space will eventually get a -ENODEV for the protected context creation which is the correct behavior and we don't create unnecessary drm_error's in our dmesg (for what is unsupported platforms). Changes from prio revs: v2 : - remove unnecessary newline. (Jani) v1 : - print incorrect version from input packet, not output.

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 fixes from Heiko Carstens: - Add various missing READ_ONCE() to cmpxchg() loops prevent the compiler from potentially generating incorrect code. This includes a rather large change to the s390 specific hardware sampling code and its current use of cmpxchg_double(). Do the fix now to get it out of the way of Peter Zijlstra's cmpxchg128() work, and have something that can be backported. The added new code includes a private 128 bit cmpxchg variant which will be removed again after Peter's rework is available. Also note that this 128 bit cmpxchg variant is used to implement 128 bit READ_ONCE(), while strictly speaking it wouldn't be necessary, and _READ_ONCE() should also be sufficient; even though it isn't obvious for all converted locations that this is the case. Therefore use this implementation for for the sake of clarity and consistency for now. - Fix ipl report address handling to avoid kdump failures/hangs. - Fix misuse of #(el)if in kernel decompressor. - Define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36, caused by the recently changed discard behaviour. - Make sure _edata and _end symbols are always page aligned. - The current header guard DEBUG_H in one of the s390 specific header files is too generic and conflicts with the ath9k wireless driver.
