2015-10-19powerpc/cell: Drop CONFIG_TUNE_CELL in favour of CONFIG_CELL_CPUMichael Ellerman
The TUNE_CELL option allows you to build a kernel that runs on multiple CPUs but is tuned (ie. optimised) to run on Cell CPUs. Now days no one is building a distro in that fashion, and any users who are building custom kernels for their Cell machines are better off building with CONFIG_CELL_CPU, which builds a kernel that only runs on Cell and therefore can be optimised even more aggresively. Dropping the option also avoids confusing other users, who are presented with an option to tune for Cell when they are not building for a Cell CPU at all.

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.

2015-08-27powerpc/powernv: Enable LEDS supportVasant Hegde
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.

2015-08-18powerpc/pseries: enable RTC class supportVaibhav Jain
A working rtc kernel driver is needed so that hwclock can synchronize system clock to rtc during shutdown/boot. We already have a powernv platform rtc driver located at drivers/rtc/rtc-opal.c. However it depends on CONFIG_RTC_CLASS which is disabled by default. Hence the driver isn't enabled and not compiled for the powernv kernel. We fix this by enabling rtc class support in pseries defconfig which enables this driver and compiles it into the pseries kernel. In case CONFIG_PPC_POWERNV is not enabled we fallback to 'Generic RTC support' driver which emulates the legacy 'PC RTC driver'.

2015-08-07powerpc/85xx: Use kconfig fragmentsScott Wood
Unify mpc85xx and corenet configs using fragments, to ease maintenance and avoid the sort of drift that the previous patch fixed. Hardware and software options are separated, with the hope that other embedded platforms could share the software options, and to make it easier to maintain custom/alternate configs that focus on either hardware or software options. Due to the previous patch, this patch should not affect the results of any of the affected defconfigs -- only how those results are achieved. The resulting config is more or less the union of the options that any of the configs previously selected. No attempt was made in this (or the previous) patch to edit out questionable options, but this patch will make it easier to do so in future patches.

Since commit 100832abf065bc18 ("usb: isp1760: Make HCD support optional"), CONFIG_USB_ISP1760_HCD is automatically selected when needed.

2015-06-02powerpc/configs: Replace pseries_le_defconfig with a Makefile target using ↵Cyril Bur
merge_config Rather than continuing to maintain a copy of pseries_defconfig with CONFIG_CPU_LITTLE_ENDIAN enabled, use the generic merge_config script and use an le.config to enable little endian on top of pseries_defconfig without the need for a duplicated _defconfig file. This method will require less maintenance in the future and will ensure that both 'defconfigs' are always in sync. It is worth noting that the seemingly more simple approach of: pseries_le_defconfig: pseries_defconfig $(Q)$(MAKE) le.config Will not work when building using O=builddir. The obvious fix to that: pseries_le_defconfig: $(Q)$(MAKE) -f $(srctree)/Makefile pseries_defconfig le.config Also does not work. This is because if we have for example: config FOO depends on CPU_BIG_ENDIAN select BAR Then BAR will be enabled by the first call to kconfig (via pseries_defconfig), and then will remain enabled after we merge le.config, even though FOO will have been turned off. The solution is to ensure to only invoke the kconfig logic once, after we have merged all the config fragments. This ensures nothing is select'ed on that should then be disabled by the later merged configs. This is done through the explicit call to make olddefconfig Signed-off-by: Cyril Bur <cyrilbur@gmail.com> Reviewed-by: Samuel Mendoza-Jonas <sam.mj@au1.ibm.com> [mpe: Massage change log, fix white space and use ARCH not SRCARCH] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
2015-06-02powerpc/configs: Merge pseries_defconfig and pseries_le_defconfigCyril Bur
These two configs should be identical with the exception of big or little endian. The big endian version has XMON_DEFAULT turned on while the little endian has XMON_DEFAULT not set. It makes the most sense for defconfigs not to use xmon by default, production systems should get back up as quickly as possible, not sit in xmon. In the event debugging is required, the option can be enabled or xmon=on can be specified on commandline.

git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux Pull more powerpc updates from Michael Ellerman: "Here's some more updates for powerpc for 3.18. They are a bit late I know, though must are actually bug fixes. In my defence I nearly cut the top of my finger off last weekend in a gruesome bike maintenance accident, so I spent a good part of the week waiting around for doctors. True story, I can send photos if you like :) Probably the most interesting fix is the sys_call_table one, which enables syscall tracing for powerpc. There's a fix for HMI handling for old firmware, more endian fixes for firmware interfaces, more EEH fixes, Anton fixed our routine that gets the current stack pointer, and a few other misc bits" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux: (22 commits) powerpc: Only do dynamic DMA zone limits on platforms that need it powerpc: sync pseries_le_defconfig with pseries_defconfig powerpc: Add printk levels to setup_system output powerpc/vphn: NUMA node code expects big-endian powerpc/msi: Use WARN_ON() in msi bitmap selftests powerpc/msi: Fix the msi bitmap alignment tests powerpc/eeh: Block CFG upon frozen Shiner adapter powerpc/eeh: Don't collect logs on PE with blocked config space powerpc/eeh: Block PCI config access upon frozen PE powerpc/pseries: Drop config requests in EEH accessors powerpc/powernv: Drop config requests in EEH accessors powerpc/eeh: Rename flag EEH_PE_RESET to EEH_PE_CFG_BLOCKED powerpc/eeh: Fix condition for isolated state powerpc/pseries: Make CPU hotplug path endian safe powerpc/pseries: Use dump_stack instead of show_stack powerpc: Rename __get_SP() to current_stack_pointer() powerpc: Reimplement __get_SP() as a function not a define powerpc/numa: Add ability to disable and debug topology updates powerpc/numa: check error return from proc_create powerpc/powernv: Fallback to old HMI handling behavior for old firmware ...

git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux Pull powerpc updates from Michael Ellerman: "Here's a first pull request for powerpc updates for 3.18. The bulk of the additions are for the "cxl" driver, for IBM's Coherent Accelerator Processor Interface (CAPI). Most of it's in drivers/misc, which Greg & Arnd maintain, Greg said he was happy for us to take it through our tree. There's the usual minor cleanups and fixes, including a bit of noise in drivers from some of those. A bunch of updates to our EEH code, which has been getting more testing. Several nice speedups from Anton, including 20% in clear_page().
