[PATCH] fix kexec asm
While testing kexec and kdump we hit problems where the new kernel would
freeze or instantly reboot. The easiest way to trigger it was to kexec a
kernel compiled for CONFIG_M586 on an athlon cpu. Compiling for CONFIG_MK7
instead would work fine.
The patch fixes a few problems with the kexec inline asm.

DASD allows to open a device as soon as gendisk is registered, which means the

[PATCH] fix file counting
I have benchmarked this on an x86_64 NUMA system and see no significant
performance difference on kernbench. Tested on both x86_64 and powerpc.
The way we do file struct accounting is not very suitable for batched
freeing. For scalability reasons, file accounting was
constructor/destructor based. This meant that nr_files was decremented
only when the object was removed from the slab cache. This is susceptible
to slab fragmentation. With RCU based file structure, consequent batched
freeing and a test program like Serge's, we just speed this up and end up
with a very fragmented slab -
llm22:~ # cat /proc/sys/fs/file-nr
587730 0 758844
At the same time, I see only a 2000+ objects in filp cache. The following
patch I fixes this problem.
This patch changes the file counting by removing the filp_count_lock.
Instead we use a separate percpu counter, nr_files, for now and all
accesses to it are through get_nr_files() api. In the sysctl handler for
nr_files, we populate files_stat.nr_files before returning to user.
Counting files as an when they are created and destroyed (as opposed to
inside slab) allows us to correctly count open files with RCU.

[PATCH] rcu batch tuning
This patch adds new tunables for RCU queue and finished batches. There are
two types of controls - number of completed RCU updates invoked in a batch
(blimit) and monitoring for high rate of incoming RCUs on a cpu (qhimark,
qlowmark).
By default, the per-cpu batch limit is set to a small value. If the input
RCU rate exceeds the high watermark, we do two things - force quiescent
state on all cpus and set the batch limit of the CPU to INTMAX. Setting
batch limit to INTMAX forces all finished RCUs to be processed in one shot.
If we have more than INTMAX RCUs queued up, then we have bigger problems
anyway. Once the incoming queued RCUs fall below the low watermark, the
batch limit is set to the default.

mount options: uid/gid=forget and uid/gid=ignore. Without any options the
id in core and on disk always match. Giving uid/gid=nnn specifies a
default ID to be used in core when the on disk ID is -1. uid/gid=ignore
forces the in core ID to allways be used no matter what the on disk ID is.
uid/gid=forget forces the on disk ID to always be written out as -1.
The use of these options allows you to override ownerships on a disk or

without permissions issues that would require root to correct.

The point of the smaps "shared" is to count the number of pages that are
mapped by more than one process, according to Mauricio Lin. However, smaps
uses page_count for this, so it will return a false positive for every page
that is mapped by just that one process, which is also in pagecache or
swapcache. There are false positive situations for anonymous pages not in
swapcache as well: - page reclaim, migration - get_user_pages (eg.
direct-io, ptrace)
Use page_mapcount instead, to count the number of mappings to the page.
Use vm_normal_page so that weird things like /dev/mem aren't counted either.

[PATCH] ramfs needs to update directory m/ctime on symlink
ramfs neglects to update the directory mtime and ctime fields when creating
a new symbolic link. Ramfs was modified in 2.6.15 to update these fields
when other types of entries are created. The symlink support is separate
from that other support, so that change did not cover quite all of the

[PATCH] numa_maps update
Change the format of numa_maps to be more compact and contain additional
information that is useful for managing and troubleshooting memory on a
NUMA system. Numa_maps can now also support huge pages.
Fixes:
1. More compact format. Only display fields if they contain additional
information.
2. Always display information for all vmas. The old numa_maps did not display
vma with no mapped entries. This was a bit confusing because page
migration removes ptes for file backed vmas. After page migration
a part of the vmas vanished.
3. Rename maxref to maxmap. This is the maximum mapcount of all the pages
in a vma and may be used as an indicator as to how many processes
may be using a certain vma.
4. Include the ability to scan over huge page vmas.
New items shown:
dirty
Number of pages in a vma that have either the dirty bit set in the
page_struct or in the pte.
file=<filename>
The file backing the pages if any
stack
Stack area
heap
Heap area
huge
Huge page area. The number of pages shows is the number of huge
pages not the regular sized pages.
swapcache
Number of pages with swap references. Must be >0 in order to
be shown.
active
Number of active pages. Only displayed if different from the number
of pages mapped.
writeback
Number of pages under writeback. Only displayed if >0.

[SERIAL] Fix two bugs in parport_serial
Steinar H. Gunderson reported:
- For some reason, it detects the 9845 as a 9735 -- it appears this is
simply related to the ordering in parport_serial_pci_tbl[]. If we move
the 9845 up above the 9735, it prints out 9710:9845, but no change in
behaviour. (We didn't find out why this was the case; we left it alone
since it didn't affect our problem.)
- The card has no parallel port (at least no physical ones), yet it reports
(via its subsystem ID of 0x0014) one parallel port and four serial ports.
The probe for the parallel port fails, and the driver just aborts. Thus,
it doesn't find the serial ports.
Fix the debugging code to use dev_dbg, but don't bother displaying the
PCI ID of the detected board (that's accessible via other means.)
Also, arrange for parport_register() to return 0 even if it finds no
ports.

[CIFS] Always match oplock break (cache notification) to the right tcp
session when multiply mounted.
Fixes slow response when cifs client is mounted to shares on multiple
servers and oplock break occurs (usually due to attempt to multiply open a
file). When treeids on mutiple mounted shares match and we find the wrong
match first, we searched for the wrong cached files to send oplock break
response for which usually meant that no matching file was found and thus
the server would have to timeout the notification. Oplock break timeout is
about 20 seconds on some servers so this could cause significantly slower
performance on file open calls in a few cases (in particular when multiple
shares are mounted from multiple servers, tree ids match, and we have a
cached file which is later opened multiple times). This was the most
important of the bugs that was found and fixed at Connectathon

[PATCH] Add missing ifdef for VIA RNG code
Almost all the code for the VIA RNG is guarded with __i386__ #ifdefs,
the only exception being the enumeration of RNG types which is used to
index into the rng_vector ops array. This patch adds an ifdef around
that for consistency and since the guard makes a difference when adding
new RNG types on non-i386 hardware.

On some platforms readq performs additional work to make sure I/O is done
in a coherent way. This is not needed for time retrieval as done by the
time interpolator. So we can use readq_relaxed instead which will improve
performance.
It affects sparc64 and ia64 only. Apparently it makes a significant

[PATCH] v9fs: simplify fid mapping
v9fs has been plagued by an over-complicated approach trying to map Linux
dentry semantics to Plan 9 fid semantics. Our previous approach called for
aggressive flushing of the dcache resulting in several problems (including
wierd cwd behavior when running /bin/pwd).
This patch dramatically simplifies our handling of this fid management. Fids
will not be clunked as promptly, but the new approach is more functionally
correct. We now clunk un-open fids only when their dentry ref_count reaches 0
(and d_delete is called).
Another simplification is we no longer seek to match fids to the process-id or
uid of the action initiator. The uid-matching will need to be revisited when
we fix the security model.
