The pcnet32 driver will hang after a few frames (<30) with the 79C971
(and probably the 79C972 though I don't have the hardware to prove it).
By interrupting slightly more frequently the hang will not occur.

Ok, found it.

It really looks like the new EISA probing code in hp100 never got
tested, since a precious offset has disappeared during the rewriting
process.

Please note that you still need to enable the device by hand, since
your BIOS (or maybe the EISA CFG file, since I'm seeing the exact same
problem on a Compaq machine here) doesn't properly enable the card.

Here is what I'm getting on my test system :

EISA: Probing bus 0 at 0000:00:0f.0
EISA: Mainboard CPQ0541 detected.
EISA: slot 1 : DEC4250 detected.
EISA: slot 2 : UNB0048 detected.
EISA: slot 3 : HWP1940 detected (forced enabled).
hp100: Using (slow) programmed i/o mode.
hp100: at 0x3c38, IRQ 3, EISA bus, 128k SRAM (rx/tx 75%).
hp100: Adapter is attached to 10Mb/s network (10baseT).
EISA: slot 4 : NVL0701 detected.

Now we've moved the bogolock code out to stop_machine.c and
generalized it a little, use it in module.c and delete the duplicate
code there.

The "bogolock" code was introduced in module.c, as a way of freezing
the machine when we wanted to remove a module.  This patch moves it
out to stop_machine.c and stop_machine.h.

Since the code changes affinity and proirity, it's impolite to hijack
the current context, so we use a kthread.  This means we have to pass
the function rather than implement "stop_machine()" and
"restart_machine()".

Committing a transaction creating a file required insuring that the
inode stayed in cache until the journal was written to.  i_count was
being incremented until the transaction was complete.

However, incrementing i_count caused fcntl(S_SETLEASE) to fail.  I
reworked the transaction code so that the inode does not have to
stay in-memory while the transaction is being committed.

Thanks to Steve French for figuring out why setlease was failing.

When no iocharset is specified, the default action is to trivially
map each byte into the low order of the 16-bit unicode character.
If an existing name exists that has a non-zero high order byte, the
file will be inaccessible without remounting with iocharset set to
a charset that supports the character.

This patch will cause a warning to be issued to the syslog (no more
than five times) suggesting that the volume be mounted with
iocharset=utf8 in order to access the file.

Fixes bugzilla #2219

fork's dup_mmap leaves child mm_rb as copied from parent mm while doing all
the copy_page_ranges, and then calls build_mmap_rb without holding
page_table_lock.

try_to_unmap_one's find_vma (holding page_table_lock not mmap_sem) coming
on another cpu may cause mm mayhem.  It may leave the child's mmap_cache
pointing to a vma of the parent mm.

When the parent exits and the child faults, quite what happens rather
depends on what junk then inhabits vm_page_prot, which gets set in the page
table, with page_add_rmap adding the ptep, but junk pte likely to fail the
tests for page_remove_rmap.

Eventually the child exits, the page table is freed and try_to_unmap_one
oopses on null ptep_to_mm (but in a kernel with rss limiting, usually
page_referenced hits the null ptep_to_mm first).

This took me days and days to unravel!  Big thanks to Matthieu for
reporting it with a good test case.

It provides a best-effort, minimum-latency "get all the writeout
underway" function.

blk_start_queue() fix.

Noted by Stephen Smalley: sys_acct does not properly clean up the open
file when the security_acct hook returns an error.

Fixed thus.

Here's the second attempt at fixing blk_start_queue().  The only change
since last version is using proper atomic bitops.  If we moved the
read/write full to a different variable, we could rely on the queue lock
for plugging and stop/start of queue (by far the most used bit
operations there) and skip the atomic bitops.

Patch from Horms <horms@vergenet.net>

1. The trailing '\n' was missing, it has been added
2. The protocol is already in host byte order,
   the ntohl() call has been removed

into nuts.davemloft.net:/disk1/BK/tg3-2.6

blk_insert_request() unconditionally calls q->request_fn(q) regardless
of the plug state of the queue. This means that we could invoke
request_fn with a plugged queue, which is an invalid state.

Also fix a Jamesism style in there.

filemap_flush() needs exporting for modular XFS builds.

This got missed in my cleanup if iSeries_vio_dev.

The attached patch updates wanXL card driver. Please apply to Linux 2.6.
Thanks.

Changes:
* fixed initialization kernel panic, introduced with recent alloc_netdev()
  wan patch,
* wanxl_rx_intr() port# now checked before accessing port structure,
* cleanups etc.

Use %08llx for a dma_addr_t, not the recently-added %llx.

The carmel driver will want to use this rather
than muck around in queue internals directly.

Declarations come before statements, please.

Current gcc warns about this too, bless them:

It looks like a block request snuck through before we had initialised the
