[POWERPC] Split several platforms into their respective Kconfig file Moved pseries, iseries, chrp, prep, maple and pasemi into their respective arch/powerpc/platform/*/Kconfig files out of arch/powerpc/Kconfig Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

powerpc/kconfig: Kill PPC_MULTIPLATFORM CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't really meaningful anymore. It was basically equivalent to PPC64 || 6xx. This removes it along with the following changes: - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely on 6xx which is what they want anyway. - A new symbol, PPC_BOOK3S, is defined that represent compliance with the "Server" variant of the architecture. This is set when either 6xx or PPC64 is set and open the door for future BOOK3E 64-bit. - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use PPC64 && PPC_BOOK3S - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now used to control the use of prom_init.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

powerpc: pci config cleanup Choosing PCI or not at config time is allowed on some platforms via an if expression in arch/powerpc/Kconfig. To add a new platform with PCI support selectable at config time, you must change the if expression. This patch makes this easier by changing: bool "PCI support" if <long expression> to bool "PCI support" if PPC_PCI_CHOICE and adding select PPC_PCI_CHOICE to all the config nodes that were previously in the PCI if expression. Platforms with unconditional PCI support continue to just select PCI in their config nodes.

powerpc: Merge enough to start building in arch/powerpc. This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting. Signed-off-by: Paul Mackerras <paulus@samba.org>

[POWERPC] Add CONFIG_PPC_PSERIES_DEBUG to enable debugging for platforms/pseries Add a DEBUG config setting which turns on all (most) of the debugging under platforms/pseries. To have this take effect we need to remove all the #undef DEBUG's, in various files. We leave the #undef DEBUG in platforms/pseries/lpar.c, as this enables debugging printks from the low-level hash table routines, and tends to make your system unusable. If you want those enabled you still have to turn them on by hand. Also some of the RAS code has a DEBUG block which causes a functional change, so I've keyed this off a different (non-existant) debug #define. This is only enabled if you have PPC_EARLY_DEBUG enabled also. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

With this option a system running in an LPAR can be given more
memory than physically available and will allow firmware to
balance memory across many LPARs.
config CMM
tristate "Collaborative memory management"
powerpc: Disable Collaborative Memory Manager for kdump When running Active Memory Sharing, the Collaborative Memory Manager (CMM) may mark some pages as "loaned" with the hypervisor. Periodically, the CMM will query the hypervisor for a loan request, which is a single signed value. When kexec'ing into a kdump kernel, the CMM driver in the kdump kernel is not aware of the pages the previous kernel had marked as "loaned", so the hypervisor and the CMM driver are out of sync. This results in the CMM driver getting a negative loan request, which can then get treated as a large unsigned value and can cause kdump to hang due to the CMM driver inflating too large. Since there really is no clean way for the CMM driver in the kdump kernel to clean this up, simply disable CMM in the kdump kernel. This fixes hangs we were seeing doing kdump with AMS.

help
Select this option, if you want to enable the kernel interface
to reduce the memory size of the system. This is accomplished
by allocating pages of memory and put them "on hold". This only
makes sense for a system running in an LPAR where the unused pages
will be reused for other LPARs. The interface allows firmware to
balance memory across many LPARs.
