Based on input from Roland McGrath and Hugh Dickins.

This simplifies the logic, and takes advantage of the
"new" VM information in the form of vma->anon_vma.

Rather than the deprecated remap_page_range() function
that can't handle all of the PFN range anyway.

Also, since that will now mark the vma as being special,
there's no need to do it in mmap_mem() any more.

VM_IO tells the rest fo the world that the pages may
have side effects on reads/writes etc, and VM_RESERVED
historically told swap-out not to bother with it.

It was pointed out to me that I typo'd and lost a backslash in the
PA-RISC io_remap_page_range() definition. This patch corrects the
one-character typo.

I reviewed, patched, and tested ppp_async.c to implement
ldisc->hangup().  This correctly terminates the PPP connection on
hangup.

Paul Mackerras already did an excellent job of ensuring safe shutdown
and I/O completion in ldisc->close so the change is trivial: just add
the ldisc->hangup and call the existing close routine.

The memset is because it was previously possible to send always the same CIFS
fragment and use this to increase the data counters.  When the data counter
"exceeds" the amount of bytes expected this will return the buffer only
partially initialised...  With findfirst etc requests this should allow
leaking kernel memory content.

The other thing is that the data is only returned when data_tot and parm_tot
both "exceed" the expected values.  Previously it was possible to create a
sequence of CIFS fragments that allowed exceeding the counters.  The calling
functions then would believe they received a number of bytes that does not fit
into the allocated buffer.

When a system has a very large imbalance of overall memory size to
ZONE_NORMAL (for example when large amounts of numa remap space are in use)
page_writeback_init() may incorrectly set vm_dirty_ratio and
dirty_background_ratio to zero; leading to divide by zero errors elsewhere.
This patch bounds these at 1%.

In ia32 emulation, the amd64 kernel refuses the ioctls TIOCSBRK and
TIOCCBRK with EINVAL.  I've attached a patch that adds them to the
compatibility list.

Since all architectures have these ioctls ("m68knommu" inherits them from
"m68k", "um" from its host) and use the same code, I think adding them to
compat_ioctl.h is the correct choice (as opposed to adding them to
arch/x86_64/ia32/ia32_ioctl.c).

When the generic IRQ patch went in, it changed the behaviour of setup_irq
(compared to the previous ppc64 version) in that we now don't call the
handler's enable function if it has a startup function.  The XICS interrupt
controller has a startup function, and so we weren't getting any interrupts
through the XICS because they never got enabled.  This patch adds a call to
xics_enable_irq to xics_startup and fixes the problem.

Instead, tty_io.c will always copy user space data to
kernel space, leaving the drivers to worry only about
normal kernel buffers.

No more "from_user" flag, and having the user copy in
each driver.

locking bugs.

Patch from Todd Poynor

Mostly from Eric Biederman for supporting BIOS flash.

    - Move support firmware hub style lock and unlock into fhw_lock.h (from cfi_cmdset_0002)
    - Move cfi_varsize_frob into cfi_util from cfi_cmdset_0001.c and cfi_cmdset_0002.c
    - reduce gen_probe probe failuers to a debug level message
    - Modify cfi_fixup to take a struct mtd_info instead of a struct map_info
      So that the fixup routines can modify the mtd functions.
    - Modify cfi_cmdset_0001() to allocate and initialize the mtd structure
      before calling cfi_fixup.
    - Modify cfi_cmdset_0002() to allocate and initialize the mtd structure
      before calling cfi_fixup.
    - Refactor the hard coded fixups in cfi_cmdset_0001 and cfi_cmdset_0002
      so the improved cfi_fixup infrastructure.
    - Rewrote amd76xrom and ichxrom.
      They now report their starting physical address in their name.
      They now both handle multiple bankwidth configurations
      They both can create multipe mtd devices.
      They both now assume the rom windows are properly opened by the BIOS
       or whatever runs previous to them.
      Their code is now synchromized so it is almost identical,
         and could be a starting point for a x86_rom_probe.
