Fix what seems to be a typo preventing .../power/state from working.

The x86 build depends on NR_VECTORS being defined. 

This symbol, however, was put only into mach-default/irq_vectors.h

The attached patch adds it to voyager too.

The reworked firmware loader in the DVB patches needs the fix to the
call_usermodehelper() return value. 

From: Rusty Russell <rusty@rustcorp.com.au>

MODULE_ALIAS_BLOCK() and MODULE_ALIAS_CHAR() define aliases of form
"XXX-<major>-<minor>", so we should probe for modules using this form.
Unfortunately in 2.4, block aliases were "XXX-<major>" and char aliases
were of both forms.

Ideally, all modules would now be using MODULE_ALIAS() macros to define
their aliases, and the old configuration files wouldn't matter as much. 
Unfortunately, this hasn't happened, so we make request_module() return the
exit status of modprobe, and then do fallback when probing for char and
block devices.

(Kudos to Chris Wright, I stole his kernel_thread flags).

This removes dead PCI-related code from the i82365 driver.

From: David Hinds <dhinds@sonic.net>

This changes the PCMCIA CIS parsing code to use kmalloc() rather than
allocating some data structures on the kernel stack.

From: David Hinds <dhinds@sonic.net>

This fixes interrupt allocation for 16-bit PCMCIA cards, so that on systems
supporting ISA bus interrupts, if all ISA interrupts are unavailable, we'll
fall back on sharing the bridge PCI interrupt.

From: David Hinds <dhinds@sonic.net>

This fixes half/full duplex selection for certain NE2000 compatible PCMCIA
cards.

From: David Hinds <dhinds@sonic.net>

This just sets missing logging levels for printk's in yenta_socket.

From: David Hinds <dhinds@sonic.net>

I have not been actively maintaining PCMCIA for 2.6; I tried asking the
more active developers to see if someone would step into the job but they
were not willing to do so at this time.  I'll still submit patches from
time to time.

(David has a ./CREDITS entry, of course).

We should really put in Russell King here, but I'll let him do that
himself.

PPC32: Fix the mkprep util to work correctly on Solaris 8.

- There is a very odd problem with the alignment of dword_t values
  which causes this program to not work correctly when compiled on
  Solaris 8.  The workaround is not use a pointer and to memcpy the
  values instead.

Fix compilation of arch/ppc/kernel/ppc_ksyms.c on !CONFIG_PPC_STD_MMU

'mol_trampoline' is only defined on CONFIG_PPC_STD_MMU.  Therefore this file
will not compile on !CONFIG_PPC_STD_MMU without this change.

From: Tom Rini <trini@kernel.crashing.org>

The following patch fixes the 'znetboot' and 'znetbootrd' targets so that
they work again.

- Update the comments to reflect how things work with the correct
  usages now.

- Fix the znetboot / znetbootrd targets.  We now always set end-y,
  and use this to figure out what image will be tftpboot'ed.

From: Tom Rini <trini@kernel.crashing.org>

Currently a number of Motorola PPC32 machine will not boot, as the final
zImage isn't built correctly for them.

The compiler justly complains in this:

	        unsigned int regnr = *(loff_t *) v, i;

	        if (regnr == 0) {
	                seq_puts(p, "     ");
	#ifdef CONFIG_SMP
	                for (i = 0; i < NR_CPUS; i++)
	#endif
	                        seq_printf(p, "      CPU%02d ", i);

That i is uninitialised if CONFIG_SMP is not set.

From: Ram Pai <linuxram@us.ibm.com>

I have enclosed a patch that fixes a bunch of performance bugs in the
readahead code.

Below is a brief summary of the problems noticed and the proposed fixes
with some results:
   
 Problem 1:  Readahead code closes the readahead window and goes into
 slowread path, if a file is accessed the first time at an offset
 notequal to zero.  In the case of databases(especially in db2), a file
 may not be accessed at offset 0 the first time though the i/o's are
 sequential.

 Fix to Problem 1:
          min = get_min_readahead(ra);
         orig_next_size = ra-next_size;

 -       if (ra-next_size == 0 && offset == 0) {
 +       if (ra-next_size == 0) {

------------------------------------------------------------------------

 ------------------------------------------------------------------------
 Problem 2: After fixing Problem, the readahead window still does not
 open up the first time, if all the pages requested are already in the
 page cache. This time the window closes because of pagecache hits
 instead of misses. To fix this we put in these changes.

 -               check_ra_success(ra, ra-size, actual, orig_next_size);
 +               if(!first_access) {
 +                       check_ra_success(ra, ra-size, actual, orig_next_size);
 +               }

 ------------------------------------------------------------------------

 ------------------------------------------------------------------------
 Problem 3: In the case of large random reads, the readahead window is
 read in, the moment there is a hit in the active window. And it turns
 out that in most of the cases the readahead window gets scrapped,
 because the next large random read does not even touch any of the pages
 in that readahead window. We fixed this by introducing lazy readahead.
 Basically we wait till the last page in the active window gets a hit.
 And once the last page is hit, the readahead window is then read in.
 This fix gave a tremendous boost in the performance.
 To fix this the changes we put in were:

                 /*
                  * This read request is within the current window.  It is time
                  * to submit I/O for the ahead window while the application is
                  * crunching through the current window.
                  */
 -               if (ra-ahead_start == 0) {
 +               if (ra-ahead_start == 0 && offset == (ra-start + ra-size -1)) {

 ------------------------------------------------------------------------

 ------------------------------------------------------------------------
 Problem 4:
       If the request page does not fall in the active window and is not
the  first page of the read ahead window, we scrap both the active
window and the readahaed window and read in the active window. But it
turns out that we read in a lot of pages in the active window based on
the size of the 'projected readahead window size' (the next_size
variable). And we end up using part of the active window and waste the
remaining. We put  in a fix where we read in just as many pages in the
active window based on the number of pages used in the recent past.
 Again this gave us another big boost in performance and ended up
beating the performance of aio patch on a DSS workload.

 The fix to this is:
                  * ahead window and get some I/O underway for the new
                  * current window.
                  */
 +               if (!first_access && preoffset = ra-start &&
 +                               preoffset < (ra-start + ra-size)) {
 +                       ra-size = preoffset - ra-start + 2;
 +               } else {
 +                       ra-size = ra-next_size;

 ------------------------------------------------------------------------

 ------------------------------------------------------------------------
 Problem 5:
 With all the above fixes there is very low chance that the readahead
 window shall close.  But however if it does, we found that the slow
 read  path is really slow.  Any loss of sequentiality in the slow read
 path is penalized heavily by closing the window back to zero. So we
 fixed this  by decreasing the window size by one anytime we loose
 sequentiality and  increasing in by 1 if we didn't.

                 if (offset != ra-prev_page + 1) {
 -                       ra-size = 0;            /* Not sequential */
 +                       ra-size = ra-size?ra-size-1:0; /*Notsequential */

 ------------------------------------------------------------------------

With the above set of fixes we got about 28% improvement in DSS workload
which is about 5% more than what we got with the suparna's aio patch.

This patch compared equivalent to suparna's aio patch with aio-stress
run.

It fared better than aio patch for large random io.

We are yet to run a bunch of other benchmarks to evaluate this patch.
We would like to get your inputs on this patch and any suggestions you
may have to improve it. I have enclosed a patch with all these changes
along with some changes to the comments that reflect the new behaviour.
NOTE: the above patch reverts suparna's aio patch.

From: Hans Ulrich Niedermann <linux-kernel@n-dimensional.de>

I've noted that 2.6.0 contains broken references to documentation.

I got sufficiently annoyed chasing doc files in the wrong place
that I wrote a script to check the references to documentation
files.

Some documentation files have moved (e.g.  Documentation/modules.txt to
Documentation/kbuild/modules.txt).  I adapted the references with a script.

From: Nikita Danilov <Nikita@Namesys.COM>

This patches reiserfs_rename.  It adds ctime update of renamed object.  It
also fixes calculation of maximal possible transaction size during rename.

Thanks to Alex Adriaanse <alex_a@caltech.edu> for finding this.

From: Nikita Danilov <Nikita@Namesys.COM>

Add "commit" reiserfs mount option to override maximal transaction age. 
Usage:

mount -treiserfs -ocommit=<time-in-seconds> /device /mountpoint

From: Nikita Danilov <Nikita@Namesys.COM>

Patch to teach fs/reiserfs/super.c:reiserfs_fill_super() to respect @silent
parameter and to not issue any output if @silent is set.

Also remove some trailing white spaces, while we are here.
