Update ES1371 to new synchronize_irq() API.

line_length, type and visual moved from display struct to the fb_info's fix
structure during last fbdev updates. Unfortunately generic code was not updated
together, so now every fbdev driver is broken.

Characters 0x80-0x9F from ISO encodings are U+0080-U+009F, so map
them both ways. Otherwise you cannot use chars 0x80-0x9F in filenames
on filesystems using NLS.

We don't need to reenable interrupts before calling panic.

support using work done by Kai Makisara (on st driver, posted
2002/7/29).

Changelog:
    Changes since 3.5.26 (20020708)
        - re-add direct IO using Kai Makisara's work
        - re-tab to 8, start using C99-isms
        - simplify memory management

Like Kai's patch, this one needs kernel/ksyms.c altered
to export get_user_pages(). Kai's worker routines
st_map_user_pages() and st_unmap_user_pages() are duplicated
as is. Hopefully these routines will find a home in
a library soon.

The re-tabbing makes the patches rather large so here
are 2 urls:
This tarball contains sg.h and sg.c 
	http://www.torque.net/sg/p/sg3527.tgz
This gzipped patch is against lk 2.5.31 and touches
kernel/ksyms.c as well
	http://www.torque.net/sg/p/sg_3527_lk2531.diff.gz

Testing is ongoing, everything works apart from "zero
copy" copy. That uses mmap-ed IO on the read side and
direct IO on the write side. Not too many people would
be using that I suspect.

Linus,
Below is a patch to a file that documents the interface
between the scsi mid level and lower level (HBA) drivers.

The main change is documenting "autosense". bios_param()'s
interface has changed.

support for per driver parameters added in lk 2.5.31

1.62 changes:
  - driverfs support for these options (more to come):
    /driverfs/bus/scsi/drivers/scsi_debug/delay [rw]
    /driverfs/bus/scsi/drivers/scsi_debug/num_devs [r]
    /driverfs/bus/scsi/drivers/scsi_debug/opts [rw]
  - start using some C99
  - fdisk requires EINVAL from unsupported ioctls
    (scsi_debug previously used ENOTTY)

1.61 changes:
  - simulate delayed responses, controlled by
    'scsi_debug_delay'
  - support REPORT LUNS
  - support more MODE SENSE pages
  - [following Doug Ledford's suggestion] do autosense
    (i.e. set Scsi_Cmnd::sense_buffer array appropriately
     when a status of CHECK CONDITION is set)
  - minor driverfs support
  - start adding error injection logic, see
    "scsi_debug_every_nth"

The device_root device was only a placeholder device that provided a head
for the global device list, and a parent directory for root bridge devices.

This removes the device and replaces with an explicit global_device_list 
and a separate root directory. We never used any of the other fields in 
device_root, and we special cased it. So, it's better off dead.

This just adds an if switch to irq_balance which the compiler optimises
away anyway.

This patch that adds a prctl so that processes can set their
floating-point exception mode on PPC and on PPC64.  We need this
because the FP exception mode is controlled by bits in the machine
state register, which can only be accessed by the kernel, and because
the exception mode setting interacts with the lazy FPU save/restore
that the kernel does.

The patch allows userspace to issue printk's, via sys_syslog().

The main use of this is within hpa's klibc - initial userspace needs a
way of logging information and this API allows that information to be
captured into the printk ringbuffer.  It ends up in /var/log/messages.

Messages are truncated at 1024 characters by printk's vsprintf().

Requires CAP_SYS_ADMIN.

JFS needs this.

Convert ext2 initialisers to c99 format.  From Art Haas.

Make sure we delete devices from the driver list the iteration after we 
detach them (so we can get a valid next pointer)

- I changed the sector_t thing in max_block to use davem's approach.
  I agree with Anton, but making it explicit doesn't hurt.

- Remove a dead comment in copy_strings.

Old stuff:

- Remove the IO error warning in end_buffer_io_sync().  Failed READA
  attempts trigger it.

- Emit a warning when an ext2 is mounting an ext3 filesystem.

  We have had quite a few problem reports related to this, mainly
  arising from initrd problems.  And mount(8) tends to report the
  fstype from /etc/fstab rather than reporting what has really
  happened.

Fixes some bogosity which I added to max_block():

- `size' doesn't need to be sector_t

- `retval' should not be initialised to "~0UL" because that is
  0x00000000ffffffff with 64-bit sector_t.

- Allocate task_structs with GFP_KERNEL, as discussed.

- Convert the EXPORT_SYMBOL for generic_file_direct_IO() to
  EXPORT_SYMBOL_GPL.  That was only exported as a practicality for the
  raw driver.

- Make the loop thread run balance_dirty_pages() after dirtying the
  backing file.  So it will perform writeback of the backing file when
  dirty memory levels are high.  Export balance_dirty_pages to GPL
  modules for this.

  This makes loop work a lot better - I suspect it broke when callers
  of balance_dirty_pages() started writing back only their own queue.

  There are many page allocation failures under heavy loop writeout.
  Coming from blk_queue_bounce()'s allocation from the page_pool
  mempool.  So...

- Disable page allocation warnings around the initial atomic
  allocation attempt in mempool_alloc() - the one where __GFP_WAIT and
  __GFP_IO were turned off.  That one can easily fail.

- Add some commentary in block_write_full_page()

get_page_state() is showing up on profiles on some big machines.  It is
a quite expensive function and it is being called too often.

The patch replaces the hardwired RATELIMIT_PAGES with a calculated
amount based on the amount of memory in the machine and the number of
CPUs.
