Manual fixup of:
arch/powerpc/Kconfig
-
Because the pte is now 64-bits the compiler was optimizing the update
to always clear the upper 32-bits of the pte. We need to ensure the
clr mask is treated as an unsigned long long to get the proper behavior.Signed-off-by: Kumar Gala

The new dma_attrs support must only be enabled for 64 bits as it's not
been implemented for 32 bits yet.Signed-off-by: Benjamin Herrenschmidt
-
This patch adds support to the RGMII handler in the EMAC driver for
the MII PHY mode such that device tree entries of the form `phy-mode = "mii";'
are recognized and handled appropriately.While logically, in software, "gmii" and "mii" modes are the same,
they are wired differently, so it makes sense to allow DTS authors to
specify each explicitly.Signed-off-by: Grant Erickson

Push the sync below the secondary smp init hold loop and comment its purpose.
This should speed up boot by reducing global traffic during the single-threaded
portion of boot.Signed-off-by: Sonny Rao

VSX loads and stores will take an alignment exception when the address
is not on a 4 byte boundary.This add support for these alignment exceptions and will emulate the
requested load or store.Signed-off-by: Michael Neuling
Signed-off-by: Benjamin Herrenschmidt -
giveup_vsx didn't save the FPU and VMX regsiters. Change it to be
like giveup_fpr/altivec which save these registers.Also update call sites where FPU and VMX are already saved to use the
original giveup_vsx (renamed to __giveup_vsx).Signed-off-by: Michael Neuling

Implement save_stack_trace_tsk on powerpc, so that we can run with
latencytop.Signed-off-by: Arnd Bergmann
Signed-off-by: Benjamin Herrenschmidt -
It is okay for both _PAGE_GUARDED and _PAGE_COHERENT (G and M) to be set
in the same pte. In fact, even if that were not the case, there doesn't
seem to be any place where G is set without also setting I (_PAGE_NO_CACHE),
so the test for I is sufficient as a condition to clear _PAGE_COHERENT
when filling the hash table.Signed-off-by: Dave Kleikamp

Background from Maynard Johnson:
As of POWER6, a set of 32 common events is defined that must be
supported on all future POWER processors. The main impetus for this
compat set is the need to support partition migration, especially from
processor P(n) to processor P(n+1), where performance software that's
running in the new partition may not be knowledgeable about processor
P(n+1). If a performance tool determines it does not support the
physical processor, but is told (via the
PPC_FEATURE_PSERIES_PERFMON_COMPAT bit) that the processor supports
the notion of the PMU compat set, then the performance tool can
surface just those events to the user of the tool.PPC_FEATURE_PSERIES_PERFMON_COMPAT indicates that the PMU supports at
least this basic subset of events which is compatible across POWER
processor lines.Signed-off-by: Nathan Lynch

Adds a character driver for BSR support on IBM POWER systems including
Power5 and Power6. The BSR is an optional processor facility not currently
implemented by any other processors. It's primary purpose is fast large SMP
synchronization. More details on the BSR are in comments to the code which
follows. This patch adds BSR driver to pseries_defconfig.Signed-off-by: Sonny Rao

Commit ef3d3246a0d06be622867d21af25f997aeeb105f ("powerpc/mm: Add Strong
Access Ordering support") in the powerpc/{next,master} tree caused the
following in a powerpc allmodconfig build:usr/include/asm/mman.h requires linux/mm.h, which does not exist in exported headers
We should not use CONFIG_PPC64 in an unprotected (by __KERNEL__)
section of an exported include file and linux/mm.h is not exported. So
protect the whole section that is CONFIG_PPC64 with __KERNEL__ and put
the two introduced includes in there as well.Signed-off-by: Stephen Rothwell
