* arch/*/configs/*defconfig: Replace AUTOFS4_FS by AUTOFS_FSSven Joachim2023-07-291-1/+1
| | | | | | | | | | | | | | | | | | | | Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs") promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS within a couple of releases, but five years later this still has not happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs. Get rid of it mechanically: git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' | xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/' Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't regenerated their config file in the last five years will need to just get the new name right when they do.

They've been under test in linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam Howlett. An overlapping range-based tree for vmas. It it apparently slightly more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat at [1]. This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses clang-generated instrumentation to detect used-unintialized bugs down to the single bit level. KMSAN keeps finding bugs. New ones, as well as the legacy ones. - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of memory into THPs. - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support file/shmem-backed pages. - userfaultfd updates from Axel Rasmussen - zsmalloc cleanups from Alexey Romanov - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure - Huang Ying adds enhancements to NUMA balancing memory tiering mode's page promotion, with a new way of detecting hot pages. - memcg updates from Shakeel Butt: charging optimizations and reduced memory consumption. - memcg cleanups from Kairui Song. - memcg fixes and cleanups from Johannes Weiner. - Vishal Moola provides more folio conversions - Zhang Yi removed ll_rw_block() :( - migration enhancements from Peter Xu - migration error-path bugfixes from Huang Ying - Aneesh Kumar added ability for a device driver to alter the memory tiering promotion paths.

| | | | | | | | | | | | | | | | | This kernel configuration is basically enabling/disabling sr driver quirks detection. While these quirks are for fairly rare devices (very old CD burners, and a glucometer), the additional detection of these models is a very minimal amount of code. The logic behind the quirks is always built into the sr driver. This also removes the config from all the defconfig files that are enabling this already.

As well as quite a lot of other changes all over the place, and small fixes and cleanups as always.

* powerpc/configs: Enable I2C_CHARDEV for pseries and powernvAndrew Donnellan2017-10-221-0/+1
| | | | | | | | | | | i2c-dev provides an interface for userspace programs to interact with I2C devices, and is very helpful for I2C-related debugging. Enable it in pseries_defconfig and powernv_defconfig. It's already enabled in many other powerpc defconfigs.

* powerpc/configs: Drop unnecessary CONFIG_POWERNV_OP_PANELMichael Ellerman2017-08-281-1/+0
| | | | | | | | In commit 43a1dd9b5fc6 ("powerpc/powernv: Add driver for operator panel on FSP machines") we added CONFIG_POWERNV_OP_PANEL=m to the powernv defconfig, but it's default m so that's no necessary. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

| | | | | | | | In commit a311e738b6d8 ("powerpc/powernv: Make PCI non-optional") we made PCI (and therefore PCI_MSI) non-optional on powernv, so it doesn't need to be in the defconfig anymore. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
* powerpc/configs: Drop no longer needed CONFIG_SMP for pseries/ppc64/powernvMichael Ellerman2017-08-281-1/+0
| | | | | | | | | In commit 40e275653e2c ("powerpc/powernv: Always enable SMP when building powernv") and 270e2dc9b803 ("powerpc/pseries: Always enable SMP when building pseries") we forced CONFIG_SMP on for some configs. Therefore we don't need to set it in those configs anymore. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
* powerpc/configs: Drop unnecessary CONFIG_UPROBE_EVENTMichael Ellerman2017-08-281-1/+0
| | | | | | | | | | In commit 6b0b7551428e ("perf/core: Rename CONFIG_[UK]PROBE_EVENT to CONFIG_[UK]PROBE_EVENTS") it was renamed to CONFIG_UPROBE_EVENTS. Additionally it's default y, and we have the prerequisites enabled, so we don't need it in our defconfigs. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
* powerpc/configs: Drop no longer needed CONFIG_DEVPTS_MULTIPLE_INSTANCESMichael Ellerman2017-08-281-1/+0

* powerpc/configs: Explicitly drop CONFIG_INPUT_MOUSEDEVMichael Ellerman2017-08-281-1/+0
| | | | | | | | | | | | | | | | | In commit 73d8ef76006b ("Input: mousedev - stop offering PS/2 to userspace by default") (Jan 2017), CONFIG_INPUT_MOUSEDEV was switched from default y to default n, with the explanation: Evdev interface has been available for many years and by now everyone is switched to using it, so let's stop offering /dev/input/mouseN and /dev/psaux by default. We had a number of configs which had it enabled, but going by the above explanation probably don't need it enabled anymore. So drop the last remnants of it from our defconfigs.

* powerpc/configs: Re-enable HARD/SOFT lockup detectorsMichael Ellerman2017-08-091-1/+2
| | | | | | | | | | | | | | | | In commit 05a4a9527931 ("kernel/watchdog: split up config options"), CONFIG_LOCKUP_DETECTOR was split into two separate config options, CONFIG_HARDLOCKUP_DETECTOR and CONFIG_SOFTLOCKUP_DETECTOR. Our defconfigs still have CONFIG_LOCKUP_DETECTOR=y, but that is no longer user selectable, and we don't mention the new options, so we end up with none of them enabled. So update the defconfigs to turn on the new SOFT and HARD options, the end result being the same as what we had previously.

| | | | | | | | | | It turns out cloud-config uses ISO9660 filesystems to inject configuration data into cloud images. The cloud-config failures when ISO9660_FS is not enabled are cryptic, and building it in makes mainline testing easier, so re-enable it.
