This patch from Pat Mochel cleans up the hell that was mtrr.c
into something a lot more modular and easy to understand, by
doing the implementation-per-file as has been done to various
other things by Pat and myself over the last months.

It's functionally identical from a kernel internal point of view,
and a userspace point of view, and is basically just a very large
code clean up.

one of the debugging tests triggered a false-positive BUG() when a
detached thread was straced.

it is much cleaner to pass in the address of the user-space VM lock -
this will also enable arbitrary implementations of the stack-unlock, as
the fifth clone() parameter.

It's referenced by mips and mips64 (both far out of date), but never
actually defined anywhere.

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.

Moves some functions that are only used by usbfs to be private, and
documents some of the interface issues that need to be cleaned up.

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.
