This patch fixes a receive hang that occasionally occurs after a Tx
FIFO underrun.  The receive dma remains in a hung state sometimes.  The
transmit operations continue to occur, but no receive activity.

This was reproduced on several ppc64 systems and the fix has been verified
there.  The patch has been tested as well on an ia32 system, which did
not experience the hang because it did not have fifo underruns, which is
a preqrequisite for the hang.  The memory barriers decreased the frequency
of occurrence.  The final change to reset the chip instead of just stopping
it eliminated the last hangs.

Please also apply against 2.4.7 (with offset of -1), tested ia32.

This patch will discard received frames that are larger than one buffer.
This has been tested on ia32 and ppc64 systems.

Please also apply to 2.4.7 (with offset of -3), tested ia32.

This contains hpfs fixes from my source ported to 2.6.7 kernel:

updates:
- allocator fragments files less
- OS/2 Warp Server filesystem can be mounted read/only
- added reschedule points so that it doesn't hog CPU

bug fixes:
- filesystem error message when syncing or fsyncing deleted file (or when
  system just writes it on its own)
- filesystem error on extremly fragmented files
- corrupted disk structures could possibly corrupt memory

In base kernel 2.6.7, there is bug in function hugetlb_prefault().  The
call to free_huge_page() is incorrect and should be replaced with a call
to page_cache_release().

This patch moves the pfm_ovfl_arg_t structure from the kernel stack
into the pfm_context_t structure. This minimizes kernel stack space
consumption.

- Handle the overlapping mmaps in the MAP_FIXED case
- Handle unmaps correctly i.e. call __ia32_delete_pp_range()
- There are now three clear entry points into the pp manipulation code
        - ia32_set_pp
        - ia32_unset_pp
        - ia32_compare_pp
- Rename internal functions to __ia32_*pp_*
- Grab mmap_sem just once at the main entry point

This enhances the network simulation scheduler to do simple random loss.

The loss parameter is a simple 32 bit value such that 0 means no loss, and
0xffffffff is always drop.  I have a new version of the tc command which takes
care of conversion from percent to this value.

Same patch for 2.4 and 2.6

Sigh...  First of all, LSI folks have very quaint idea of existing
platforms and word sizes on those.  Their definitions of U32 and S32
should really be reserved for posterity (preferably chiseled into the
rock they have between the ears), but kernel is the wrong place for
that.  Fixed.

mptctl_do_mpt_command() was always called on userland pointers;
kernel/userland argument removed along with dead code, function
annotated, callers updated.

The rest is trivial annotations in mptctl.c and in its ioctl structures
- nothing fancy there.

Last 3 users of kernel_scsi_ioctl() eliminated; two of them used to read
partition table by issuing a READ6 via ioctl (instead of just calling
scsi_bios_ptable() as every other ->biosparam() instance does).

The last one was doing a very quaint access to fields of scsi_device by
issuing SCSI_IOCLT_GET_LUN and then shuffling bits in the result.  Down
with that insanity...

If delay scheduler decides not to send the packet right away, it requeues
it.  If the requeue fails, it should go and look again rather than waking
up prematurely.

Same patch should apply to both 2.6 and 2.4
