This wire up the: fallocate, timerfd_create, timerfd_settime,
timerfd_gettime, signalfd4, eventfd2, epoll_create1, dup3, pipe2,
inotify_init1, preadv, pwritev and rt_tgsigqueueinfo syscalls for
the alpha port.
For umount2, alpha have an "old" and "new" version called: oldumount and
umount; so ignore umount2.

Fixed non-conflicting clean merge of modpost.c as per comments from
Stephen Rothwell (modpost.c had grown an include of linux/autoconf.h
that needed to be changed to generated/autoconf.h)
spin_* functions are mostly static inline now. That causes the alpha
compile to fail:
CC arch/alpha/kernel/sys_sable.o
cc1: warnings being treated as errors
In file included from arch/alpha/kernel/sys_sable.c:25:
arch/alpha/include/asm/core_t2.h: In function 't2_readb':
arch/alpha/include/asm/core_t2.h:451: error: 'spinlock_check' is static but \
used in inline function 't2_readb' which is not static
arch/alpha/include/asm/core_t2.h:456: error: 'spin_unlock_irqrestore' is \
static but used in inline function 't2_readb' which is not static
That's caused by the "extern inline" magic which is used for the
subarch specific read/write[bwl] functions. I tried to distangle the
uncountable macro onion layers, but failed miserably.
Last resort solution: switch the t2_hae_lock to raw_spinlock_t so the
lock functions are pure macros and function calls again.

The raw_spin* namespace was taken by lockdep for the architecture
specific implementations. raw_spin_* would be the ideal name space for
the spinlocks which are not converted to sleeping locks in preempt-rt.
Linus suggested to convert the raw_ to arch_ locks and cleanup the
name space instead of using an artifical name like core_spin,
atomic_spin or whatever
No functional change.

The simplest method was to add an extra asm-offsets.h
file in arch/$ARCH/include/asm that references the generated file.
We can now migrate the architectures one-by-one to reference
the generated file direct - and when done we can delete the
temporary arch/$ARCH/include/asm/asm-offsets.h file.

While Linux provided an O_SYNC flag basically since day 1, it took until
Linux 2.4.0-test12pre2 to actually get it implemented for filesystems,
since that day we had generic_osync_around with only minor changes and the
great "For now, when the user asks for O_SYNC, we'll actually give
O_DSYNC" comment. This patch intends to actually give us real O_SYNC
semantics in addition to the O_DSYNC semantics. After Jan's O_SYNC
patches which are required before this patch it's actually surprisingly
simple, we just need to figure out when to set the datasync flag to
vfs_fsync_range and when not.
This patch renames the existing O_SYNC flag to O_DSYNC while keeping it's
numerical value to keep binary compatibility, and adds a new real O_SYNC
flag. To guarantee backwards compatiblity it is defined as expanding to
both the O_DSYNC and the new additional binary flag (__O_SYNC) to make
sure we are backwards-compatible when compiled against the new headers.
This also means that all places that don't care about the differences can
just check O_DSYNC and get the right behaviour for O_SYNC, too - only
places that actuall care need to check __O_SYNC in addition. Drivers and
network filesystems have been updated in a fail safe way to always do the
full sync magic if O_DSYNC is set. The few places setting O_SYNC for
lower layers are kept that way for now to stay failsafe.
We enforce that O_DSYNC is set when __O_SYNC is set early in the open path
to make sure we always get these sane options.
Note that parisc really screwed up their headers as they already define a
O_DSYNC that has always been a no-op. We try to repair it by using it for
the new O_DSYNC and redefinining O_SYNC to send both the traditional
O_SYNC numerical value _and_ the O_DSYNC one.

The removal of the TIF_NOTIFY_RESUME flag, commit a583f1b542
"remove unused TIF_NOTIFY_RESUME flag," resulted in incorrect
setting of the unaligned access control flags by the prctl syscall.
The re-addition of the TIF_NOTIFY_RESUME flag, commit d0420c83f3
"KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures [try #6]"
further caused problems, namely incorrect operands to assembler code
as evidenced by:
AS arch/alpha/kernel/entry.o
arch/alpha/kernel/entry.S: Assembler messages:
arch/alpha/kernel/entry.S:326: Warning: operand out of range
(0x0000000000000406 is not between 0x0000000000000000 and
0x00000000000000ff)
Both regressions fixed by (1) rearranging TIF_NOTIFY_RESUME flag to be
in lower 8 bits of the thread info flags, and (2) making sure that
ALPHA_UAC_SHIFT matches the rearrangement of the thread info flags.

Mtdblock driver doesn't call flush_dcache_page for pages in request. So,
this causes problems on architectures where the icache doesn't fill from
the dcache or with dcache aliases. The patch fixes this.
The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid
pointless empty cache-thrashing loops on architectures for which
flush_dcache_page() is a no-op. Every architecture was provided with this
flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is
equal 1 or do nothing otherwise.
See "fix mtd_blkdevs problem with caches on some architectures" discussion
on LKML for more information.

These values were only introduced during this release cycle, so it is
still early enough to get them right.
alpha uses the same values that are in asm-generic/fcntl.h, so just
remove them.
parisc uses the values interchanged for no apparent reason, so remove
them to give us consistency across all architectures.

alpha: Clean up linker script using new linker script macros.
Note that .data.page_aligned and .data.cacheline_aligned are now after
_data; it was probably a bug that they were before it.
Also, some explicit ALIGN(8)'s between various initcall sections were
removed; this should be harmless as the implicit alignment of
initcall_t was already 8.
