2021-01-29arch: powerpc: Stop building and using oprofileViresh Kumar
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). Note that the member "oprofile_cpu_type" in "struct cpu_spec" isn't removed as it was also used by other parts of the code.

2020-02-24scsi: sr: remove references to BLK_DEV_SR_VENDOR, leave it enabledDiego Elio Pettenò
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.

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.

Remove the CONFIG_UEVENT_HELPER_PATH because: 1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was made default to 'n', 2. It is not recommended (help message: "This should not be used today [...] creates a high system load") and was kept only for ancient userland, 3.

2018-12-20powerpc/configs: Don't enable PPC_EARLY_DEBUG in defconfigsMichael Ellerman
This reverts the remains of commit b9ef7d6b11c1 ("powerpc: Update default configurations"). That commit was proceeded by a commit which added a config option to control use of BOOTX for early debug, ie. PPC_EARLY_DEBUG_BOOTX, and then the update of the defconfigs was intended to not change behaviour by then enabling the new config option. However enabling PPC_EARLY_DEBUG had other consequences, notably causing us to register the udbg console at the end of udbg_early_init(). This means on a system which doesn't have anything that BOOTX can use (most systems), we register the udbg console very early but the bootx code just throws everything away, meaning early boot messages are never printed to the console. What we want to happen is for the udbg console to only be registered later (from setup_arch()) once we've setup udbg_putc, and then all early boot messages will be replayed.

2016-11-14powerpc: convert ppc64_defconfig to use libata PATA driversBartlomiej Zolnierkiewicz
IDE subsystem has been deprecated since 2009 and the majority (if not all) of Linux distributions have switched to use libata for ATA support exclusively. However there are still some users (mostly old or/and embedded non-x86 systems) that have not converted from using IDE subsystem to libata PATA drivers. This doesn't seem to be good thing in the long-term for Linux as while there is less and less PATA systems left in use: * testing efforts are divided between two subsystems * having duplicate drivers for same hardware confuses users This patch converts ppc64_defconfig to use libata PATA drivers.
