unlike v2/v3, nfsv4 returns nfserr_inval when attempting to read, write,
commit or test lock a symlink.  nfsv4 does return nfserr_symlink on lookup
and open, so a simple fix in fh_verify() will not work.

[PATCH] kNFSd: When looking for a shareowner in the nfsd open, make sure we don't get a lockowner instead.

From: NeilBrown <neilb@cse.unsw.edu.au>

When looking for a shareowner in the nfsd open, make sure we don't get a
lockowner instead.

[PATCH] kNFSd: Use only the uid when deciding whether a setclientid is being done with the "same principal".

From: NeilBrown <neilb@cse.unsw.edu.au>

I would have assumed that we should also check for the same security
(pseudo)flavor, but that doesn't seem to be how Solaris does it, and since
the spec doesn't suggest including such information in the clientid, that
would make it impossible to switch pseudoflavors.

From: NeilBrown <neilb@cse.unsw.edu.au>

Since the open op changes the current filehandle, we can't correctly replay
compounds containing opens unless we save the filehandle resulting from the
open as well as the encoded reply.

Use higher-resolution time for the changeinfo, instead of using time and
filesize.

From: NeilBrown <neilb@cse.unsw.edu.au>

Exclusive creates were failing with permission errors, because they don't set
the mode on the newly created file, and the permission check in fh_verify
(called at the end of do_open_lookup) was failing.  So pass in the
MAY_OWNER_OVERRIDE flag to allow the owner of the file to override the
permission check.

From: NeilBrown <neilb@cse.unsw.edu.au>

It's OK for the find_lockstateowner_str to fail; that just means we haven't
seen the lockowner, and will compare the request range to all locks on the
file.

Compare inode pointers instead of dentry pointers when checking an inode
refered to by a stateid against an inode refered to by a file handle.

Set st_vfs_set to 0 if the stateid/file handle check fails to avoid
referencing bad state when reaping stateid's.

Doesn't actually add integrity support on the server yet; just adapts
server-side code to the gss api changes necessary to get integrity working on
the client.

Note that the user (or exportfs, on the user's behalf) allows a gss
pseudoflavor to be used to access an export by exporting to a special client
named "gss/pseudoflavor-name", e.g., "gss/krb5" or "gss/lipkey-i".

Make sure nfsd doesn't modify group_info structures as they might be

Tidy up new groups handling in nfsd.

ppc64 uses its own range allocator for ioremap (in order to allocate
things in a different space than normal vmalloc).  This is historic stuff,
we may get rid of it, but in the meantime, here's a patch turning the
spinlock in there into a semaphore so it doesn't blow up when doing
kmallocs.

This moves the sg_dma_* macros to asm/scatterlist.h where they belong (and
where almost every other architecture has them).

Use the new kallsyms_lookup_name() in xmon on ppc64.  Ben said he might
backport these changes to ppc32 as well.

From: Rusty Russell <rusty@au1.ibm.com>

Attached patch adds a kallsyms_lookupname() function for lookups of a
symbol name to an address.  Debuggers such as ppc[64] xmon can use this.

It's intentionally not exported as a symbol for module use, since it
can be used to circumvent other symbol export restrictions.

Add the PPC64 iSeries virtual disk driver

into ppc970.osdl.org:/home/torvalds/v2.5/linux

This helps avoid doing push/pop pairs on register contents that we just
don't care about. After we've done the xor, the pointers are dead anyway.

into ppc970.osdl.org:/home/torvalds/v2.5/linux

into kernel.bkbits.net:/home/davem/net-2.6

Since we do push/pops, a stack-based memory argument would
do the wrong thing by using the wrong offsets.

The x86-64 implementation of csum-partial.c causes it to compute the
checksum incorrectly.

As a result, multicast doesn't work.  It looks as though iptables is
also affected.

Here's a simple patch.

This patch is the first of several planned fixes for the cyclades
multiserial cards driver.

Its mostly a sync with in-house driver:

- Prevent users from opening non-existing Z ports
- Implement special XON/XOFF character handling in Z cards
- Prevent data-loss on Z cards
- Throttling fix for Z card
- Only throttle if CTS/RTS are set
- Fix accounting of received data

Kudos to Cyclades R&D

PRD_ENTRIES is specified to be precisely 256; on platforms where
PAGE_SIZE varies from 4KB the calculation in the current expression
defining it is inaccurate, which may cause crashes. This patch changes
it to the constant literal 256.

Use sector_t for the block number.
