This patch moves some unnecessary global functions to the local
pnpbios include file.

It looks like this option has been moved from isapnp to resource.c,
but the MODULE_PARM line is still there:

The original argument for blocking DMA 0 was to avoid conflicts with
"memory refresh"  but such configurations are only found on very old
8-bit systems that are likely not supported by the linux kernel. 
This patch allows dma 0 to be assigned to PnP devices by default.  If
for whatever reason dma 0 cannot be used, one can avoid allocating it
by setting the pnp_reserve_dma= kernel parameter.

This patch moves the detection code to a more appropriate file.

When a driver's probe routine fails, it may not release all of the
card devices it requested.  This patch allows the pnp layer to ensure
that all devices claimed by the failing driver are released properly.

Here's an updated patch that will correct the compile error when PROC
FS is disabled.  It also introduces better proc error recovery and
moves the local proc functions to the local include file.  Thanks to
Daniele Bellucci for finding the problem and contributing to this
patch.

This fixes the thread-aware /proc for CONFIG_SECURE.

bad_flp_intr() in floppy.c can cause an Oops if the I/O request is freed
but <errors> still points into the I/O request block.  Get the error
count out of the request block before ending the IO.

Fix a few error-path leaks in the cciss block driver.  Bug found by smatch

make_pages_present() can fail: propagate that failure back.

If a request is merged with another, it sometimes has to be repositioned on
the rbtree - you just do a delete then an add.  This is a quite uncommon
case though.

I changed the way adding works, so collisions must be handled by the caller
instead of being dumbly fixed by the add routine.  Unfortunately the
uncommon callers weren't handling it properly.

the zoran kernel driver is called 'zoran.o' in its CVS (historical thing, I
don't know why), and it's called zr36067.o in the kernel tree.  The
documentation in the kernel tree refers to zoran.o, though, which is (in
the kernel tree) the driver for zr36120-based cards, rather than the driver
for zr360x7-based cards.

The attached patch fixes the documentation and makes it refer to
zr36067.o instead.

I saw a lockup where 2 cpus were stuck in sem_lock().  It seems like we can
loop back to retry_undos with the lock held.  That path takes the lock so
we will deadlock.

From: Anton Blanchard <anton@samba.org>

If init_new_context fails we definitely do not want to call mmput, because
that will call destroy_context against an uninitialised context.  Instead
we should back out what we did in init_mm.  Fixes some weird failures on
ppc64 when running a fork bomb.

This patch short-circuits all the direct-io page dirtying logic for
higher-order pages.  Without this, we pointlessly bounce BIOs up to keventd
all the time.

bio_dirty_fn() needs to drop its ref against each remaining page in the BIO
before releasing the BIO.

From: Nick Piggin <piggin@cyberone.com.au>

Fix fallout from Jens' insert_here removal.  Without it its possible that a
request on the dispatch list is on the merge hash as well which is bad.  I
don't _think_ this would happen in any code paths, but I haven't looked too
closely.  It makes the API a bit less fragile anyway.

From: James Cleverdon <jamesclv@us.ibm.com>

32-way IBM x445s will have I/O xAPICs with IDs greater than 0xF (0x8 to 0xE
isn't enough).  This breaks the code in setup_ioapic_ids_from_mpc.
However, the entire unique ID check is unnecessary.  Only I/O APICs using
the serial APIC bus need the unique numbers.  Those sending messages
through the system bus simply don't use them.

I was having a problem with signals with POSIX timers, and it turns out 
that the value of SIGRTMAX is incorrect.  Remember that there is no
signal 0, so the signals should go from 1-_NSIG.  However, SIGRTMAX is
defined as (_NSIG-1) in all architectures.  The following patch fixes this.

This define is only used in drivers/usb/core/devio.c and 
kernel/posix-timers.c, and both are incorrect without this fix.  There's
also no check for zero in posix-timers.c, that fix is part of the diff.

Also, shouldn't do_sigaction() use this value instead of _NSIG?  It's
not a big deal, but some architectures have different values for _NSIG
and SIGRTMAX.

I have an old Genius Colorpage-SP2 SCSI scanner.  It is shipped with a
MS-PNR 8bit ISA non-pnp proprietary SCSI card from Microtek.

Although its chipset is a NCR53c400a, it wouldn't work with the appropriate
driver, always accusing timeout, whatever settings I passed to it.

Today I messed a little with the NCR5380.c file in drivers/scsi which is
included by the g_NCR5380 driver and I couldn't understand one thing:

Why the function NCR5380_poll_politely() returned the value 'r' on success
if this value should be '0' case everything went ok...

So I changed "return r;" to "return 0;" and after that my scanner worked
fine, and was easily detected by SANE, without a single error message.  :)

I have not the time to delve into the problem further, but I wanted to
report this.  I couldn't find any counter-effects caused by changing these
return values.

Since monotonic_clock() is not defined on every arch yet, this patch
insures the hangcheck-timer module (currently the only user of
monotonic-clock) is not built where it will not compile.

I know, I know. Ideally monotonic_clock() would be implemented on all
arches, but I've just not had the time.  If any of the non x86/x86-64
folks feel bored, drop me a line.  It'd be a fairly easy project.

Nobody told me that the failure to export these (like their block
counterparts) was anything but an oversight; modules will not be able to
use larger device numbers without them.  So...this patch exports the new
char device functions.

While trying to figure out why sysv msg is around 30% slower than pipes for
data transfers I noticed that gcc's autodetection (3.2.2) guesses the
"if(access_ok())" tests in uaccess.h wrong and puts the error memset into the
direct path and the copy out of line.

So tell the compiler that access_ok() is likely to be true.

This is a driver for SBE Inc.  wanXL 4-port sync serial card, second

From: James Cleverdon <jamesclv@us.ibm.com>

In forthcoming IBM x445 systems, the physical APIC ID will not follow the
simple rule laid out by Intel and encoded into xapic_phys_to_log_apicid.
(The BIOS code that sets IDs doesn't work right above 16 CPUs if HT is turned 
on, so for > 16-way the BIOS will disable HT and repack the physical CPUs
into APIC clusters.)

Anyway, it's a good idea to make the APIC code more independent of any
particular BIOS numbering scheme.  This patch allocates logical IDs based on
how many CPUs have already been onlined in a particular APIC cluster.

Two drivers are #including the same .c file.  Use them both and we get a

When someone specifies "init=" to select an alternative binary to run
instead of /sbin/init, argv[0] is not set correctly.  This is a problem for
programs such as busybox that multiplex applications based on the value of
argv[0].  For example, even if you specify init=/bin/sh" on the kernel
command line, busybox will still receive "/sbin/init" as argv[0] and will
therefore run init rather than /bin/sh...

This patch fixes a memory leak in the file locking code.  Each attempt to
unlock a file would result in the leak of a file lock.  Many thanks to
