powerpc: Fix pte_update for CONFIG_PTE_64BIT and !PTE_ATOMIC_UPDATES
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.

ibm_newemac: Add MII mode support to the EMAC RGMII bridge.
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.

powerpc: Add PPC_FEATURE_PSERIES_PERFMON_COMPAT
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.

We should not use CONFIG_PPC64 in an unprotected (by __KERNEL__)

protect the whole section that is CONFIG_PPC64 with __KERNEL__ and put

[S390] sclp_tty: Fix scheduling while atomic bug.
Finally fixes a possible scheduling while in atomic context bug. The driver
used to wait on a waitqueue if no empty buffer was available. This could
lead to a deadlock if the driver was called from non-schedulable context.
So fix this. The write operation may fail now. It returns the number of
characters accepted. put_char will never fail, since it writes characters
to an intermediate buffer which gets flushed as soon as it is full.
That means the driver now can busy wait if something is in the intermediate
buffer and a write_string operation follows. Seems to be an acceptable
compromise, since that shouldn't happen too often.

[S390] drivers/s390: Eliminate NULL test and memset after alloc_bootmem
As noted by Akinobu Mita in patch
b1fceac2b9e04d278316b2faddf276015fc06e3b,
alloc_bootmem and related functions never return NULL and always return a
zeroed region of memory. Thus a NULL test or memset after calls to these
functions is unnecessary.

Some macros in pgtable.h access members from struct task_struct.
Currently always works since sched.h seems always to be included
before asm/pgtable.h. Unfortunately that is not anymore true with
Jeremy Fitzhardinge's ptep_modify_prot transaction abstraction patch.
So fix this.
