* powerpc: convert ppc64_defconfig to use libata PATA driversBartlomiej Zolnierkiewicz2016-11-141-6/+3Star
| | | | | | | | | | | | | | | | | | | | 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.

* powerpc/configs: Bump kernel ring buffer size on 64 bit configsAnton Blanchard2016-10-041-0/+2
| | | | | | | | | | | | | When we issue a system reset, every CPU in the box prints an Oops, including a backtrace. Each of these can be quite large (over 4kB) and we may end up wrapping the ring buffer and losing important information. Bump the base size from 128kB to 256kB and the per CPU size from 4kB to 8kB.

* powerpc/configs: Re-enable CONFIG_SCSI_DHMichael Ellerman2015-09-291-1/+1
| | | | | | | | | | | | | | | Commit 086b91d052eb ("scsi_dh: integrate into the core SCSI code") changed CONFIG_SCSI_DH from tristate to bool. Our defconfigs have CONFIG_SCSI_DH=m, which the kconfig machinery warns us is invalid, but instead of converting it to =y it leaves it unset. This means we loose the CONFIG_SCSI_DH code and everything that depends on it. So convert the values in the defconfigs to =y.

* powerpc/powernv: Enable LEDS supportVasant Hegde2015-08-271-0/+3
| | | | | | | | | | | | | | | | | | | Commit 84ad6e5c added LEDS support for PowerNV platform. Lets update ppc64_defconfig to pick LEDS driver. PowerNV LEDS driver looks for "/ibm,opal/leds" node in device tree and loads if this node exists. Hence added it as 'm'. Also note that powernv LEDS driver needs NEW_LEDS and LEDS_CLASS as well. Hence added them to config file. mpe: Also add them to pseries_defconfig, which is currently also used for powernv systems.

| | | | | | | | | | | | | | | | | The celleb code has seen no actual development for ~7 years. We (maintainers) have no access to test hardware, and it is highly likely the code has bit-rotted. As far as we're aware the hardware was never widely available, and is certainly no longer available, and no one on the list has shown any interest in it over the years. So remove it.
