This is against 2.5.5 ...

Here is a batch of accumulated bugfixes and cleanups for the Coda kernel
module. Patch is against 2.5.6-pre2, I could also send these as separate
patches.

bugfix: Fix coda_dentry_revalidate bug

    Due to a bad test, coda_dentry_revalidate was forcing revalidation
    of cacheable inodes, and allowed caching of non-cacheable inodes.

bugfix: Corrected i_mtime/i_ctime setting

    i_mtime and i_ctime were not always updated when writing to a file,
    or when modifying inode attributes.

cleanup/optimization: Avoid getattr upcalls

    We can use coda_iget directly instead of coda_cnode_make when an
    upcall returns attributes and avoid the getattr upcall altogether.

cleanup: Removed debugging messages

    CDEBUG macros haven't been useful ever since the initial development
    when they were introduced. They are too verbose for debugging
    purposes. Removing these saves about a third of the compiled size of
    the module.

    Removed print_entry variable that was used by ENTRY/EXIT macros
    which are already gone.

cleanup/optimization: Readdir simplification

    Relying on the fact that the pagecache is already buffering far more
    efficiently, simplified coda_readdir implementation. We can now fill
    the complete userbuffer instead of returning after reading only 2KB.

    Passing dir entry types that are present in the venus_dirent
    structure to the user as well.

cleanup: Removed redundant permissions statistics counters.

    The permission check count is about identical to the 'permission'
    field in the VFS stats, and the permission hit counter can trivially
    be derived from upcall_stats.access - vfs_stats.permission. Removed
    these redundant counters.

cleanup: Removed useless test for c_flags in coda_revalidate_inode.

    We already know c_flags is set due to earlier tests.

as intended.

This implements ptes-in-highmem for PPC, removes the quicklist
and zero-page stuff.  PTEs in highmem on SMP turned out to need
some significant changes to avoid deadlocks on the hash_table_lock
(now renamed to mmu_hash_lock).  The PMDs now contain the physical
address of the PTE page rather than the virtual address.
Anything that takes the mmu_hash_lock now operates with the DMMU
off to avoid MMU hash-table misses.

These are all in the 2.4.19-pre2.

quinlan@transmeta.com: [PATCH] take COPYING into new century:
	These mods are directly from the FSF version.

	This set of one-liners are the ones which have already gone
into 2.2.19-pre2.

Andrey Panin <pazke@orbita1.ru>: [PATCH] arch_i386_kernel_smpboot.c missing __init:
  this patch adds missing __init directive for div64() function
  in arch/i386/kernel/smpboot.c. div64() is only used
  synchronize_tsc_bp() function which is marked __init.

Andrey Panin <pazke@orbita1.ru>: [PATCH] remove annoying ISAPNP message:
  This patch removes useless messages like:
  "isapnp: Calling quirk for 02:00".

René Scharfe <l.s.r@web.de>: [PATCH] compiler warnings in scripts_tkgen.c:
  this patch fixes two compiler warnings during make xconfig which
  turn up if one uses -Wshadow

From: Dave Jones <davej@suse.de>
  kernel builds and boots with patch (with CONFIG_BLK_DEV_INITRD disabled).

(Trivial because CONFIG_BLK_DEV_RAM is Y if CONFIG_BLK_DEV_INITRD is Y)

	New helper:
path_lookup(name, flags, nd)
{
	int err = 0;
	if (path_init(name, flags, nd))
		err = path_walk(name, nd);
	return err;
}

Places doing that by hand converted to calling it.

Actually, quite a few of them were doing equivalent of __user_walk()
(getname() and if it was successful - call path_lookup() and putname()).
Converted to calling __user_walk().

	LOOKUP_POSITIVE is not needed anymore.  All callers of path_walk()
treat -ENOENT and negative dentry the same way.  If you want a proof of
correctness - I'll send it, but it's a couple of pages of induction, basically
boiling down to "let's show that for any N we can replace the
               if (lookup_flags & (LOOKUP_POSITIVE|LOOKUP_DIRECTORY))
                       break;
in link_path_walk() with
               if ((lookup_flags & (LOOKUP_POSITIVE|LOOKUP_DIRECTORY)) ||
		   current->link_count <= N)
                       break;
without changing behaviour of the system".  Pretty straightforward for
N = 0, then we look for places that can lead to call link_path_walk()
with current->link_count equal to N and show that if result of the test
changes, behaviour of callers doesn't.  Since the depth of recursion is
limited, we had shown that test in question can be replaced with if (1).
And that's the only place in tree the ever checks for LOOKUP_POSITIVE.

	The real reason behind that is very simple - indeed, suppose
we get a negative dentry out of path_walk().  What the hell could we
do with it?  Its parent isn't locked, so both the name and parent can
change at any moment (could have changed already).  There used to be
places that tried to play "let's get a negative dentry, lock its parent
and start doing something".  All of them racy and all of them fixed
in 2.3.  Fixed by switching to LOOKUP_PARENT...

	More cleanups (getblk() use, etc.) in reiserfs (again, cleaning
up after merge).

into mulgrave.(none):/home/jejb/BK/scsi-2.5

Tidy up and eliminate remaining references to old error handler.

SCSI reservation/reset handling

- Make both the old and the new error handlers respond correctly
  to reservation conflicts (i.e. return an I/O error).

- Add a scsi_reset_provider() function for use by the sg driver
  SCSI reset facility.

  Cleanup - remove version and changelog.
  These don't belong in Linus' kernel.

longer count the idle thread in "nr_threads", so we should
not discount it when returning sysinfo() information.

	* stat() variants on ppc64 converted to use of vfs_stat() and its ilk.
	* missing LFS checks added.

* minor cleanup in jffs (passing superblock instead of ->[si]_dev).

* in intermezzo a bunch of places where we are comparing ->s_dev
  are replaced with comparing pointers to superblocks.

* in reiserfs: a new caller of getblk() converted to sb_getblk() +
  a bunch of places converted to use of ->s_id.

* write_some_buffers(), write_unlocked_buffers(), wait_for_buffers(),
  wait_for_locked_buffers() and wait_for_some_buffers() converted
  from kdev_t to struct block_device *.

* sync_buffers() split in two functions (sync_buffers() and
  sync_all_buffers()).  Callers of sync_buffers(NODEV) are
  using the latter, those who actually pass a device - the former.
* sync_buffers() switched from kdev_t to struct block_device *.
