Michael Ellerman d0160bf0b3 [PATCH] powerpc: Rename and export ppc64_firmware_features
We need to export ppc64_firmware_features for modules. Before we do that
I think we should probably rename it to powerpc_firmware_features.

Michael Ellerman dd4d7bfad6 [PATCH] powerpc: Change firmware_has_feature() to a macro
So that we can use firmware_has_feature() in a BUG_ON() and have the compiler
elide the code entirely if the feature can never be set, change
firmware_has_feature to a macro. Unfortunate, but necessary at least until
GCC bug #26724 is fixed.

Michael Ellerman 57cfb814f6 [PATCH] powerpc: Replace platform_is_lpar() with a firmware feature
It has been decreed that platform numbers are evil, so as a step in that
direction, replace platform_is_lpar() with a FW_FEATURE_LPAR bit.

Currently FW_FEATURE_LPAR really means i/pSeries LPAR, in the future we might
have to clean that up if we need to be more specific about what LPAR actually
means. But that's another patch ...

Michael Ellerman 1965746bce [PATCH] powerpc: Move pSeries firmware feature setup into platforms/pseries
Currently we have some stuff in firmware.h and kernel/firmware.c that is
#ifdef CONFIG_PPC_PSERIES. Move it all into platforms/pseries.

Michael Ellerman 8c4f1f2958 [PATCH] powerpc: Create a trampoline for the fwnmi vectors
The fwnmi vectors can be anywhere < 32 MB, so we need to use a trampoline
for them. The kdump kernel will register the trampoline addresses, which will
then jump up to the real code above 32 MB.

Paul Mackerras 799d6046d3 [PATCH] powerpc: merge code values for identifying platforms
This patch merges platform codes.  systemcfg->platform is no longer used,
systemcfg use in general is deprecated as much as possible (and renamed
_systemcfg before it gets completely moved elsewhere in a future patch),
_machine is now used on ppc64 along as ppc32.  Platform codes aren't gone
yet but we are getting a step closer. A bunch of asm code in head[_64].S
is also turned into C code.
