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.

2022-09-05powerpc/64: Remove PPC64 special case for cputime accounting defaultNicholas Piggin1-0/+2
Distro kernels tend to be moving to VIRT_CPU_ACCOUNTING_GEN, and there is not much reason why PPC64 should be special here. Remove the special case and make the ppc64 and pseries defconfigs use GEN accounting (others will use TICK, as-per Kconfig defaults). VIRT_CPU_ACCOUNTING_NATIVE does provide scaled vtime and stolen time apportioned between system and user time, and vtime accounting is not unconditionally enabled, and possibly other things. But it would be better at this point to extend GEN to cover important missing features rather than directing users back to a less used option.

2021-11-25powerpc/pseries: delete scanlogNathan Lynch1-1/+0
Remove the pseries scanlog driver. This code supports functions from Power4-era servers that are not present on targets currently supported by arch/powerpc. System manuals from this time have this description: Scan Dump data is a set of chip data that the service processor gathers after a system malfunction. It consists of chip scan rings, chip trace arrays, and Scan COM (SCOM) registers. This data is stored in the scan-log partition of the system’s Nonvolatile Random Access Memory (NVRAM). PowerVM partition firmware development doesn't recognize the associated function call or property, and they don't see any references to them in their codebase. It seems to have been specific to non-virtualized pseries.

The "oprofile" user-space tools don't use the kernel OPROFILE support any more, and haven't in a long time. User-space has been converted to the perf interfaces. This commits stops building oprofile for powerpc and removes any reference to it from directories in arch/powerpc/ apart from arch/powerpc/oprofile, which will be removed in the next commit (this is broken into two commits as the size of the commit became very big, ~5k lines).

2020-02-24scsi: sr: remove references to BLK_DEV_SR_VENDOR, leave it enabledDiego Elio Pettenò1-1/+0
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.

2020-01-31powerpc/configs: Drop CONFIG_QLGE which moved to stagingMichael Ellerman1-1/+0
The QLGE driver moved to staging in commit 955315b0dc8c ("qlge: Move drivers/net/ethernet/qlogic/qlge/ to drivers/staging/qlge/"), meaning our defconfigs that enable it have no effect as we don't enable CONFIG_STAGING. It sounds like the device is obsolete, so drop the driver.
