powerpc: various straight conversions from module.h --> export.h

2011-10-31T23:30:44+00:00

All these files were including module.h just for the basic
EXPORT_SYMBOL infrastructure.  We can shift them off to the
export.h header which is a way smaller footprint and thus
realize some compile time gains.

powerpc: Return the_cpu_ spec from identify_cpu

2011-08-05T04:47:54+00:00

Commit af9eef3c7b1ed004c378c89b87642f4937337d50 caused cpu_setup to see
the_cpu_spec, rather than the source struct.  However, on 32-bit, the
return value of identify_cpu was being used for feature fixups, and
identify_cpu was returning the source struct.  So if cpu_setup patches
the feature bits, the update won't affect the fixups.

powerpc/book3e: Fix CPU feature handling on e5500 in 32-bit mode

2011-06-02T20:29:09+00:00

We are missing FPU feature bit that user space may require.  In the
64-bit mode this gets set since we pull it in via COMMON_USER_PPC64.  We
just explicitly set it so user space will be happy again.

powerpc: Free up some CPU feature bits by moving out MMU-related features

2011-04-27T04:18:52+00:00

Some of the 64bit PPC CPU features are MMU-related, so this patch moves
them to MMU_FTR_ bits.  All cpu_has_feature()-style tests are moved to
mmu_has_feature(), and seven feature bits are freed as a result.

powerpc: Define CPU feature for Architected 2.06 HV mode

2011-04-20T01:03:22+00:00

This bit indicates that we are operating in hypervisor mode on a CPU
compliant to architecture 2.06 or later (currently server only).

We set it on POWER7 and have a boot-time CPU setup function that
clears it if MSR:HV isn't set (booting under a hypervisor).

powerpc/book3e: Fix CPU feature handling on 64-bit e5500

2011-04-12T11:29:21+00:00

The CPU_FTRS_POSSIBLE and CPU_FTRS_ALWAYS defines did not encompass
e5500 CPU features when built for 64-bit.  This causes issues with
cpu_has_feature() as it utilizes the POSSIBLE & ALWAYS defines as part
of its check.

Create a unique CPU_FTRS_E5500 (as its different from CPU_FTRS_E500MC),
created a new group for 64-bit Book3e based CPUs and add CPU_FTRS_E5500
to that group.

powerpc: Pass the right cpu_spec to ->setup_cpu() on 64-bit

2011-02-07T01:47:57+00:00

When calling setup_cpu() on 64-bit, we pass a pointer to the
cputable entry we have found. This used to be fine when cur_cpu_spec
was a pointer to that entry, but nowadays, we copy the entry into
a separate variable, and we do so before we call the setup_cpu()
callback. That means that any attempt by that callback at patching
the CPU table entry (to adjust CPU features for example) will patch
the wrong table.

powerpc/476: define specific cpu table entry DD2 core

2011-02-02T11:58:53+00:00

The DD2 core still has some unstability.  Define CPU_FTR_476_DD2 to
enable workarounds in later patches.

This is based on an earlier, unreleased patch for DD1 by Ben Herrenschmidt.
