[PATCH] DocBook: changes and extensions to the kernel documentation
I have recompiled Linux kernel 2.6.11.5 documentation for me and our
university students again. The documentation could be extended for more
sources which are equipped by structured comments for recent 2.6 kernels. I
have tried to proceed with that task. I have done that more times from 2.6.0
time and it gets boring to do same changes again and again. Linux kernel
compiles after changes for i386 and ARM targets. I have added references to
some more files into kernel-api book, I have added some section names as well.
So please, check that changes do not break something and that categories are
not too much skewed.
I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
by kernel convention. Most of the other changes are modifications in the
comments to make kernel-doc happy, accept some parameters description and do
not bail out on errors. Changed <pid> to @pid in the description, moved some
#ifdef before comments to correct function to comments bindings, etc.
You can see result of the modified documentation build at
http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz
Some more sources are ready to be included into kernel-doc generated
documentation. Sources has been added into kernel-api for now. Some more
section names added and probably some more chaos introduced as result of quick
cleanup work.

[PATCH] ext3: remove unnecessary race then retry in ext3_get_block
The extra race-with-truncate-then-retry logic around
ext3_get_block_handle(), which was inherited from ext2, becomes unecessary
for ext3, since we have already obtained the ei->truncate_sem in
ext3_get_block_handle() before calling ext3_alloc_branch(). The
ei->truncate_sem is already there to block concurrent truncate and block
allocation on the same inode. So the inode's indirect addressing tree
won't be changed after we grab that semaphore.
We could, after get the semaphore, re-verify the branch is up-to-date or
not. If it has been changed, then get the updated branch. If we still
need block allocation, we will have a safe version of the branch to work
with in the ext3_find_goal()/ext3_splice_branch().
The code becomes more readable after remove those retry logic. The patch
also clean up some gotos in ext3_get_block_handle() to make it more
readable.

- behaviour of these helpers is same as before.

with a single __le64. Helpers are switched to straightforward shift/and/or.
Benefits:
- exact same definitions for little- and big-endian architectures; no ifdefs
in sight.
- generate the same code on little-endian and improved on big-endian.
- doesn't rely on lousy bitfields handling in gcc codegenerator.
- happens to be standard C (unsigned long long is not a valid type for a
bitfield; it's a gccism and not well-implemented one, at that).

Enable interrupts for a BT interface. There is a specific register that
needs to be set up to enable interrupts that also must be modified to clear
the irq.
Also, don't reset the BMC on a BT interface. That's probably not a good
idea as the BMC may be performing other important functions and a reset
should only be a last resort. Also, that register is also used to
enable/disable interrupts to the BT; modifying it may screw up the
interrupts.

[PATCH] vgacon: set vc_hi_font_mask correctly
When allocating a new VC with vgacon_init(), the font is shared across all
the VGA consoles. However, the font mask was always set to the default
value of zero in visual_init(), even if we were using 512 character fonts
at the time.
Moreover, code in vgacon.c:vga_do_font_op() didn't reset the mask if the
console driver thinks it's already in 512 character mode. This means that
to *fix* it, you'd actually have to take the console out of 512 character
mode and then set it back.
The attached sets vc_hi_font_mask in vgacon_init() for any new consoles

[PATCH] s390: fix memory holes and cleanup setup_arch
The memory setup didn't take care of memory holes and this makes the memory
management think there would be more memory available than there is in
reality. That causes the OOM killer to kill processes even if there is enough
memory left that can be written to the swap space.
The patch fixes this by using free_area_init_node with an array of memory
holes instead of free_area_init. Further the patch cleans up the code in
setup.c by splitting setup_arch into smaller pieces.

[PATCH] uml ubd: handle readonly status
Use the set_disk_ro() API when the backing file is read-only, to mark the disk
read-only, during the ->open(). The current hack does not work when doing a
mount -o remount.
Also, mark explicitly the code paths which should no more be triggerable (I've
removed the WARN_ON(1) things). They should actually become BUG()s probably
but I'll avoid that since I'm not so sure the change works so well. I gave it
only some limited testing.

Use this:

We already dropped the inclusion of <linux/buffer_head.h>, and we don't have a

"Without having looked at it, I'm sure that hostfs does not use buffer_heads.
So setting your ->set_page_dirty a_op to point at __set_page_dirty_nobuffers()

We must only insert the right #defines to inject the changes we need from the

don't implement some i386 syscalls, as ioperm(), nor some TLS-related ones
