New arch macro STACK_TOP_MAX it gives the larges valid stack address for the
architecture in question.
It differs from STACK_TOP in that it will not distinguish between
personalities but will always return the largest possible address.
This is used to create the initial stack on execve, which we will move down to
the proper location once the binfmt code has figured out where that is.

It is often known at allocation time whether a page may be migrated or not.
This patch adds a flag called __GFP_MOVABLE and a new mask called
GFP_HIGH_MOVABLE. Allocations using the __GFP_MOVABLE can be either migrated
using the page migration mechanism or reclaimed by syncing with backing
storage and discarding.
An API function very similar to alloc_zeroed_user_highpage() is added for
__GFP_MOVABLE allocations called alloc_zeroed_user_highpage_movable(). The
flags used by alloc_zeroed_user_highpage() are not changed because it would
change the semantics of an existing API. After this patch is applied there
are no in-kernel users of alloc_zeroed_user_highpage() so it probably should
be marked deprecated if this patch is merged.
Note that this patch includes a minor cleanup to the use of __GFP_ZERO in
shmem.c to keep all flag modifications to inode->mapping in the
shmem_dir_alloc() helper function. This clean-up suggestion is courtesy of
Hugh Dickens.
Additional credit goes to Christoph Lameter and Linus Torvalds for shaping the
concept. Credit to Hugh Dickens for catching issues with shmem swap vector
and ramfs allocations.

isa_bus_to_virt() is still needed in a few places (lance.c, at least). When
we switch the kernel to using -Werror-implicit-function-declaration, the lack
of isa_bus_to_virt() breaks alpha allmodconfig builds.
Add isa_bus_to_virt() and deprecate the ezisting ISA APIs, though it might be
better to define these functions as BUG(), since virt_to_bus/bus_to_virt just
do wrong things on a number of machines.

using, but whether they work for all of the affected architectures I can't say.
I've cc'ed as many arch maintainers/lists as I could find.

This code corrects the behavior of the t2_readX/t2_writeX routines,
and t2_ioreadNN/t2_iowriteNN routines.
The value T2_DENSE_MEM is now subtracted from the "xaddr" argument in
each of the readX/writeX routines, since those routines may be called
directly, rather than always through the ioreadNN/iowriteNN routines.
Examples of the direct calls, via the __raw_readX/writeX macros, are
the memcpy_fromio/toio, _memset_c_io, and scr_memcpyw routines.

This code replaces earlier and incomplete handling of graphics on non-zero PCI
domains (aka hoses or peer PCI buses).
An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a
kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose
SRM consoles are capable of configuring and handling graphics options on
non-zero hoses. All other machines have the option set FALSE.
A routine, "find_console_vga_hose()", is used to find the graphics device
which the machine's firmware believes is the console device, and it sets a
global (pci_vga_hose) for later use in managing access to the device. This is
called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a
custom version of this routine because of extra complexity.
A routine, "locate_and_init_vga()", is used to find the graphics device and
set a global (pci_vga_hose) for later use in managing access to the device, in
the case where "find_console_vga_hose" has failed.
Various adjustments are made to the ioremap and ioportmap routines for
detecting and translating "legacy" VGA register and memory references to the
real PCI domain.

This finally renames the thread_info field in task structure to stack, so that
the assumptions about this field are gone and archs have more freedom about
placing the thread_info structure.
Nonbroken archs which have a proper thread pointer can do the access to both
current thread and task structure via a single pointer.
It'll allow for a few more cleanups of the fork code, from which e.g. ia64
could benefit.

With the advent of kdump, the assumption that the boot CPU when booting an UP
kernel is always the CPU with a particular hardware ID (often 0) (usually
referred to as BSP on some architectures) is not valid anymore. The reason
being that the dump capture kernel boots on the crashed CPU (the CPU that
invoked crash_kexec), which may be or may not be that particular CPU.
Move definition of hard_smp_processor_id for the UP case to
architecture-specific code ("asm/smp.h") where it belongs, so that each
architecture can provide its own implementation.

atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
I agree (with Andi Kleen) this typeof is not needed and more error
prone. All the original atomic.h code that uses cmpxchg (which includes
the atomic_add_unless) uses defines instead of inline functions,
probably to circumvent a circular dependency between system.h and
atomic.h on powerpc (which my patch addresses). Therefore, it makes
sense to use inline functions that will provide type checking.
atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
Digging into the FRV architecture shows me that it is also affected by
such a circular dependency. Here is the diff applying this against the
rest of my atomic.h patches.

This patch moves the die notifier handling to common code. Previous
various architectures had exactly the same code for it. Note that the new
code is compiled unconditionally, this should be understood as an appel to
the other architecture maintainer to implement support for it aswell (aka
sprinkling a notify_die or two in the proper place)
arm had a notifiy_die that did something totally different, I renamed it to
arm_notify_die as part of the patch and made it static to the file it's
declared and used at. avr32 used to pass slightly less information through
this interface and I brought it into line with the other architectures.

Add hooks to allow a paravirt implementation to track the lifetime of
an mm. Paravirtualization requires three hooks, but only two are
needed in common code. They are:
arch_dup_mmap, which is called when a new mmap is created at fork
arch_exit_mmap, which is called when the last process reference to an
mm is dropped, which typically happens on exit and exec.
The third hook is activate_mm, which is called from the arch-specific
activate_mm() macro/function, and so doesn't need stub versions for
other architectures. It's called when an mm is first used.

Now that network timestamps use ktime_t infrastructure, we can add a new
SOL_SOCKET sockopt SO_TIMESTAMPNS.
This command is similar to SO_TIMESTAMP, but permits transmission of
a 'timespec struct' instead of a 'timeval struct' control message.
(nanosecond resolution instead of microsecond)
Control message is labelled SCM_TIMESTAMPNS instead of SCM_TIMESTAMP
A socket cannot mix SO_TIMESTAMP and SO_TIMESTAMPNS : the two modes are
mutually exclusive.
sock_recv_timestamp() became too big to be fully inlined so I added a

Files:
arch/alpha/kernel/core_mcpcia.c
arch/alpha/kernel/sys_rawhide.c
include/asm-alpha/core_mcpcia.h
Determine correct hose configuration; RAWHIDE family can have
2 or 4 hoses, so make sure non-existent hoses are ignored.
arch/alpha/kernel/err_titan.c
Supply a needed #include <asm/irq_regs.h>
arch/alpha/kernel/module.c
Add some useful output to the relocation overflow messages.
arch/alpha/kernel/sys_noritake.c
Supply necessary noritake_end_irq() to correct interrupt handling.
This fixes a problem first noted by hangs during boot probing with
a DE500-BA TULIP NIC present.
arch/alpha/kernel/sys_sio.c
Correct saving of original PIRQ register (PCI IRQ routing);
change default PIRQ setting to leave PCI IRQs 9 and 14 free to
be used for sound (Multia) and IDE (any), respectively.
include/asm-alpha/io.h
Supply the "isa_virt_to_bus" routine.

The line discipline numbers N_* are currently defined for each architecture
individually, but (except for a seeming mistake) identically, in
asm/termios.h. There is no obvious reason why these numbers should be
architecture specific, nor any apparent relationship with the termios
structure. The total number of these, NR_LDISCS, is defined in linux/tty.h
anyway. So I propose the following patch which moves the definitions of
the individual line disciplines to linux/tty.h too.
Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused
in the current kernel, but the patch still keeps the complete set in case
there are plans to use them yet.

Module loading on Alpha was failing with error "Could not allocate 8 bytes
percpu data".
Looking at dmesg we have the below error "No per-cpu room for modules."
Increase the PERCPU_ENOUGH_ROOM in a similar way as x86_64

On all targets that sucker boils down to memcpy_fromio(sbk->data, from, len).
The function name is highly misguiding (it _never_ does any checksums), the
last argument is just a noise and simply expanding the call to memcpy_fromio()
gives shorter and more readable source. For a lot of reasons it has almost
no remaining users, so it's better to just outright kill it.

there's no reason for providing it.

We went and named them __NR_sys_foo instead of __NR_foo.
It may be too late to change this, but we can at least add the proper names
now.

unionfs managed to hit this on s390. Some architectures use __ptr_t in their
FD_ZERO implementation. We don't have a __ptr_t. Switch them over to plain
old void*.

Virtually index, physically tagged cache architectures can get away
without cache flushing when forking. This patch adds a new cache
flushing function flush_cache_dup_mm(struct mm_struct *) which for the
moment I've implemented to do the same thing on all architectures
except on MIPS where it's a no-op.
