My printf manpage says:

       z      A  following  integer  conversion  corresponds to a
              size_t or ssize_t argument. (Linux libc5 has Z with
              this meaning. Don't use it.)

And the opengroup spec says

z Specifies that a following d , i , o , u , x , or X conversion specifier
  applies to a size_t or the corresponding signed integer type argument; or
  that a following n conversion specifier applies to a pointer to a signed
  integer type corresponding to a size_t argument.


yet our vsnprintf implementation has

				/* 'z' support added 23/7/1999 S.H.    */
				/* 'z' changed to 'Z' --davidm 1/25/99 */


I guess the path of least surprise is to support both.  gcc-3.2.1 doesn't
  seem to care.

The return type of sizeof() is size_t.  On many architectrues size_t is
unsigned long, and may not be printed with %d.  Use %Zu instead.

Need to reenable interrupts around the call to scsi_register(), which blocks.

An anonymous fixed mmap with CONFIG_HUGETLB_PAGE=y will dereference NULL.  We
recur into the pagefault handler with mmap_sem held and lock up.

Changes :
 - Timeout overflow check
 - Ceil()ing of ms->jif conversion
 - Syscalls return type int->long

Addresses BUGME bug #331.  "OSS CS4232 nasty spinlock printks on boot"

The locking in some OSS modules is really lousy.
Because save_flags/cli/restore_flags could be used recursivly - the
programmers pushed the locking too far the lower level.

Because on ISA cards the register sets are usually multiplexed
you had to write to an address latch and then access the data port
in an "atomic" manner.

I suggest removing the locking from ad_read/ad_write +
ad_{enter|leave}_MCE and clamping the locks wherever the functions
are called. I hope the attached patch does that correctly.

Yes, I don't like all the timeout loops while holding the locks:
high chances that a cpu is spinning in interrupt context :(

Patch from: David Mosberger <davidm@napali.hpl.hp.com>

Please remember to declare the return-type of syscall stubs as "long".
On 64-bit platforms, it's generally necessary to ensure that the
entire 64-bit return value is valid (and can be checked against
negative values).

The following patch addresses bugzilla bug # 341.

Patch from: john stultz <johnstul@us.ibm.com>

This patch simply fixes the summit subarch to allow summit kernels to
boot on normal systems.

Someone typed `config' when they meant `conf'.

Also fix a function-defined-but-not-used warning.

This driver is calling down into scsi_register with local interrupts
disabled.  scsi_register performs blocking allocations, starts kernel
threads, etc.  slab debugging gets offended by someone performing blocking
operations with local interrupts disabled.

Patch from Tim Schmielau <tim@physik3.uni-rostock.de>

Converts many open-coded jiffy comparisons to use time_after/before/etc.

Patch from Dipankar Sarma <dipankar@in.ibm.com>

All fs should be using dcache APIs to manipulate dcache hash lists.  This is
in line with the dcache cleanup patch (dcache_rcu-1) from Maneesh that Linus
accepted.  This seems like a reasonable cleanup.  One change though, we don't
need to grab dcache_lock while deleting dentries from the private list and
__d_drop() should suffice here.

make the adaptec driver compile

Patch from Rik van Riel <riel@conectiva.com.br>

the following patch, against today's BK tree, fixes a small
SMP race in disassociate_ctty.  This function gets called
from do_exit, without the BKL held.

However, it sets the *tty variable before grabbing the bkl,
then makes decisions on what the variable was set to before
the lock was grabbed, despite the fact that another process
could modify its ->tty pointer in this same function.

Patch from Oleg Drokin <green@namesys.com>, Nikita Danilov <Nikita@Namesys.COM>

There is no uniprocessor definition of _raw_write_trylock(), so
write_trylock() doesn't work on UP.

kdev_t.value is not an int.  Code looks fishy.

printk needs kernel.h

Don't assume that dev_t is unsigned.  Cast it.

cast dev_t when printing

Don't assume that dev_t is an unsigned.  Cast it.

Make the "duplicate const" warning go away.  Arguably a compiler bug...

I have a whole bunch of silly compile warning fixes here, arising from
building the kernel for a 64-bit target.  Some are trivial, some are genuine
printk bugs.

assuming dev_t is unsigned generates a warning on ppc64.  Cast it.
