Miscellaneous fixes to bring FRV up to date:
(1) Copy the new syscall numbers from i386 to asm-frv/unistd.h and fill out
the syscall table in entry.S too.
(2) Mark __frv_uart0 and __frv_uart1 __pminitdata rather than __initdata so
that determine_clocks() can access them when CONFIG_PM=y.
(3) Make arch/frv/mm/elf-fdpic.c include asm/mman.h so that MAP_FIXED is
available (fixes commit 2fd3bebaad9da3b3b99c46a3389099424bf7ee35).

The idea is to move more and more things into the pbm,
with the eventual goal of eliminating the pci_controller_info
entirely as there really isn't any need for it.
This stage of the transformations requires some reworking of
the PCI error interrupt handling.
It might be tricky to get rid of the pci_controller_info parenting for
a few reasons:
1) When we get an uncorrectable or correctable error we want
to interrogate the IOMMU and streaming cache of both
PBMs for error status. These errors come from the UPA
front-end which is shared between the two PBM PCI bus
segments.
Historically speaking this is why I choose the datastructure
hierarchy of pci_controller_info-->pci_pbm_info
2) The probing does a portid/devhandle match to look for the
'other' pbm, but this is entirely an artifact and can be
eliminated trivially.
What we could do to solve #1 is to have a "buddy" pointer from one pbm
to another.

Check if the mode can properly display the screen. This will be needed by
drivers where the capability is not constant with each mode. The function
fb_set_var() will query fbcon the requirement, then it will query the driver
(via a new hook fb_get_caps()) its capability. If the driver's capability
cannot handle fbcon's requirement, then fb_set_var() will fail.
For example, if a particular driver supports 2 modes where:
mode1 = can only display 8x16 bitmaps
mode2 = can display any bitmap
then if current mode = mode2 and current font = 12x22
fbset <mode1> /* mode1 cannot handle 12x22 */
fbset will fail

A few drivers are not capable of blitting rectangles of any dimension.
vga16fb can only blit 8-pixel wide rectangles, while s3fb (in tileblitting
mode) can only blit 8x16 rectangles. For example, loading a 12x22 font in
vga16fb will result in a corrupt display.
Advertise this limitation/capability in info->pixmap.blit_x and blit_y. These
fields are 32-bit arrays (font max is 32x32 only), ie, if bit 7 is set, then
width/height of 7+1 is supported.

Make x86 COM ports into platform devices and don't probe for them
if we have PNP.
This prevents double discovery, where a device was found both by
the legacy probe and by 8250_pnp, e.g.,
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
This also means IRDA devices without a UART PNP ID will no longer be
claimed by the serial driver, which might require changes in IRDA
drivers and administration.
In addition to this patch, you may need to configure a setserial init
script, e.g., /etc/init.d/setserial, so it doesn't poke legacy UART
stuff back in. On Debian, "dpkg-reconfigure setserial" with the "kernel"
option does this.
To force the old legacy probe behavior even when we have PNPBIOS or
ACPI, load the new legacy_serial module (or build 8250 static) with
the "legacy_serial.force" option.

This series converts i386 and x86_64 legacy serial ports to be platform
devices and prevents probing for them if we have PNP.
This prevents double discovery, where a device was found both by the legacy
probe and by 8250_pnp.
This also prevents the serial driver from claiming IRDA devices (unless they
have a UART PNP ID). The serial legacy probe sometimes assumed the wrong IRQ,
so the user had to use "setserial" to fix it.
Removing the need for setserial to make IRDA devices work seems good, but it
does break some things. In particular, you may need to keep setserial from
poking legacy UART stuff back in by doing something like "dpkg-reconfigure
setserial" with the "kernel" option. Otherwise, the setserial-discovered
"UART" will claim resources and prevent the IRDA driver from loading.
This patch:
If we can discover devices using PNP, we can skip some legacy probes. This
flag ("pnp_platform_devices") indicates that PNPBIOS or PNPACPI is enabled and
should tell us about builtin devices.

irqpoll is broken on some architectures that don't use the IRQ 0 for the timer
interrupt like IA64. This patch adds a IRQF_IRQPOLL flag.
Each architecture is handled in a separate pach. As I left the irq == 0 as
condition, this should not break existing architectures that use timer_irq ==
0 and that I did't address with that patch (because I don't know).
This patch:
This patch adds a IRQF_IRQPOLL flag that the interrupt registration code could
use for the interrupt it wants to use for IRQ polling.
Because this must not be the timer interrupt, an additional flag was added
instead of re-using the IRQF_TIMER constant. Until all architectures will
have an IRQF_IRQPOLL interrupt, irq == 0 will stay as alternative as it should
not break anything.
Also, note_interrupt() is called on CPU-specific interrupts to be used as
interrupt source for IRQ polling.

Change the atomic_t in struct nfs_server to atomic_long_t in anticipation
of machines that can handle 8+TB of (4K) pages under writeback.
However I suspect other things in NFS will start going *bang* by then.

i386:
Rearrange the cmpxchg code to allow atomic.h to get it without needing to
include system.h. This kills warnings in the UML build from atomic.h about
implicit declarations of cmpxchg symbols. The i386 build presumably isn't
seeing this because a separate inclusion of system.h is covering it over.
The cmpxchg stuff is moved to asm-i386/cmpxchg.h, with an include left in
system.h for the benefit of generic code which expects cmpxchg there.
Meanwhile, atomic.h includes cmpxchg.h.
This causes no noticable damage to the i386 build.
x86_64:
Move cmpxchg into its own header. atomic.h already included system.h, so
this is changed to include cmpxchg.h.
This is purely cleanup - it's not fixing any warnings - so if the x86_64
system.h isn't considered as cleanup-worthy as i386, then this can be
dropped.
It causes no noticable damage to the x86_64 build.
uml:
The i386 and x86_64 cmpxchg patches require an asm-um/cmpxchg.h for the
UML build.
