Linux v2.5.29
Linus Torvalds
Hmm.. All over the map. IDE patches as usual, USB updates, tons of C99
named initializers work, ACPI update, fixes from Alan, driverfs race fixes
and cleanups, SCSI driver fixes from Doug and tons of input layer updates.
Oh, and a new LDM driver, Rusty's CPU hotplug infrastructure, and Ingo's
new cleaned-up GDT code with a per-process gdt segment on x86 for
thread-local storage. And the serial and parallel port drivers seems to
work again on SMP after the big irq lock upheaval.

existence of dentry in driverfs_symlink and driverfs_mknod (which
the other creation functions use).

from ncpfs info structures
o Return total/free space on ncpfs mounted volume
o Allow access to all 256 volumes from Netware server
o Use search for fileset instead of search for one item in ncpfs. It
is much faster as you usually read whole directory in one request
when using TCP transport, instead
o Check for s_maxbytes and generate SIGXFSZ correctly in ncpfs's read
and write. Only page cache generic_file_read/generic_file_write
check for these conditions, and because of ncpfs does not use page
cache, it must do that itself.
o Update and fix inode attributes handling in ncpfs
o Utilize NFS extended attributes for storing file mode and rdev.
Make sure that you use nodev,nosuid together with nfsextras if you
do not trust server...
o Decide whether to build fs/ncpfs/symlinks.c or not in Makefile and
not through ifdefing whole file out. It should make Al happier.
o ipx use of cli/sti
Russell King <r...@flint.arm.linux.org.uk>:
o [SERIAL] Remove drivers/char/serial_{21285,amba}.c These drivers
are now part of drivers/serial
o [SERIAL] Fix documentation bug for expected stop_tx interrupt state
o [SERIAL] Fix buglet causing (eg) ttyS-14 Allocate positive instead
of negative line numbers when 8250.c registers a new port with the
core. This bug could cause registrations to erroneously fail, or
oopsen when the pcmcia serial device is ejected.
o [SERIAL] Stop open() looping while opening a non-present port
Trying to open a non-present port (for configuration) causes us to
to endlessly loop (by returning -ERESTARTSYS). We should be
returning success. This cset fixes this.
o [SERIAL] Turn on 8250 framing/parity error reporting on INPCK not
IGNPAR
o designated initalizers for serial/
o [SERIAL] Fix initialiser warnings for HUB6 ports We were missing an
element in the old_serial_port structure.
Rusty Russell <ru...@rustcorp.com.au>:
o cpu_online() has odd semantics
o Hot-plug CPU Boot Changes
o Hot-plug CPU Boot Rewrite for i386
o Hot-plug CPU Boot Rewrite for PPC
Trond Myklebust <trond.m...@fys.uio.no>:
o clean up RPC write_space() code
o increase socket buffer for RPC over UDP
o Reduce the number of getattr/lookup calls in
nfs_lookup_revalidate()
o add proper NFSv3 permissions checking
Vojtech Pavlik <voj...@suse.cz>:
o Fixes needed to get Logitech WingMan 3D running
o Kernel command line [__setup()] parsing fixes in all the input
drivers that use it, except i8042.
o Update of the X-Box USB pad driver and documentation to version
0.0.5
o This patch by Brad Hards replaces the four id* fields of the input
struct by a single struct to simplify passing it around and to
userspace.
o Add an i8042_restore_ctr command line option. This allows not
restoring the CTR value after an AUX write by default, which breaks
Transmeta Crusoe i8042 chip emulation. The option might be needed
on some ancient hardware, though.
o Fox a typo in input documentation. Patch by Pavel Machek
o Remove duplicately defined keys in input.h that got there as a part
o Osamu Tomita <tom...@cinet.co.jp>
o Fix the PS/2 mouse wheel in Explorer PS/2 mode
o Enable the Q40 keyboard only on the Q40 platform
o After some grepping and talking to maintainers, I did the appended
cleanup patch. This should be it from me until char/keyboard.c
becomes a real input layer client, but this final patch will be
_very_ small now :-)).
o The following fixes compilation errors in the Acorn related input
drivers.
o The following patch adds the "resend" capability to the keyboard
driver; when the host driver detects a parity or framing error, we
can ask the keyboard to resend the data, instead of treating random
garbage as valid data.
o This patch adds two new serio input drivers. Both are "UART" type
drivers for PS/2 ports on both StrongARM and ARM Integrator
hardware.
o Apply Rusty's C99 initializer patch to input drivers
o Add a GrIP MultiPort gamepad hub by Brian Bonnlander and Bill
Soudan
o By popular request, and explicit method of telling which events
from a device belong together was implemented - input_sync() and
EV_SYN. Touches every input driver. The first to make use of it is
mousedev.c to properly merge events into PS/2 packets.
o Small cleanup in evdev.c, which copies the data directly from input
struct to userspace.
o Add support for AT keyboards connected over a PS/2 to Serial
converter to atkbd.c - trivial. Remove ps2serkbd, because it's not
needed anymore.
o Because the Linux Input core follows the USB HID standard where it
comes to directions of movement and rotation, a mouse wheel should
be positive where it "rotates forward, away from the user". We had
the opposite in psmouse.c. Fixed this.
o Add EVIOCSABS() ioctl to change the abs* informative values on
input devices. This is something the X peoople really wanted.

I forgot to mention.. You have all been busy little critters, and I
probably missed a number of merges. Give me a day to catch my breath (and
take the kids to the aquarium), and if you think I overlooked or forgot
your patch, you should probably re-send.

Badly broken on SMP by Linus.
You'll only get one migration thread, and one ksoftirqd.
Issue is that some initcalls (softirq.c and sched.c) are way easier before
other CPUs are brought up, but doing it the other way broke AGP and Linus
decided to call all the initcalls after CPUs are brought up in case someone
else needed it (I still strongly disagree).
This hack fixes it: real fix is the explicit initcall ordering patch,
which Linus hasn't commented on 8(
Name: Hot-plug CPU Boot ksoftirqd and migration fix
Author: Rusty Russell
Status: Tested on 2.5.29, x86 SMP
D: This patch fixes the calls to initialize ksoftirqd and the
D: migration threads. This really should be done by the initcall
D: depends patch.

Again, root = hdc = cdrom with ext2 fs on it.
HW is vmware, which may be the cause of the problem (but frankly I don't
dare to run 2.5 on real hw at this point :).

tuning functions.
- Rename ide_register_subdriver() to ata_register_device() and
ide_unregister_subdriver() accordingly to ata_unregister_device(),
since this is reflecting better what those functions are about.
- Remove tons of "curicum vite" style useless documentation here and
there.
Marcin Dalecki
be just ported to u8 if I missed some place where it still gets used.
- Next round of parameter parsing cleanups by Gerald Champagne.
Adjusted a bit to harmonize with hd.c.
- Move IDE register bitfields declarations over from hdparm.h to
ide.h.
- Fixup cmd640 fix by LT.
- Don't manipulate REQ_QUEUED in blk_insert_special() as discussed on
lkml. The single only affected file is ll_rw_blk.c of course.
- Declare constants needed by hd.c directly there. Those are standard
values not subject to change and we prefer a bit of code duplication
in favour of making the two drivers independant from each other.
- Move everything not ioctl related away from hdreg.h to ide.h.
This header is in effect not private to the ATA code and should
therefore not contain stuff only usefull there.
Alan Cox
patch below instead, which removes the irq lock and uses the proper
kernel functions to enable MWI and master.
I'm not sure I like the fact you've deleted the ide-tape documentation.
IDE tape is a pretty tricky thing, especially all the command handling
weirdnesses. How about moving it into Changelog.idetape if you dont want
it in the code itself ?

The CMD640 fix is wrong. You must take pci_lock to protected the cmd640
pci access functions. You also need to check if conf1/conf2 is available
otherwise you will crash some systems when the driver init runs (found
by Justin Gibbs at Adaptec). I sent Linus the proper patch for this a
few days ago and cc'd the list.
Basically conf1/conf2 is protected elsewhere in the kernel via arch
specific locks and via a higher level config lock. Since the non x86
folks use CMD640 we have to take the higher level lock.

Yes I know. However I see the bk-tree drifting and therefore I have
postponed the integration of your patch a bit. The chunk above I did
immediately after 2.5.29 release. Hope this explains. OK?

Thanks for reaffirmation. This will be already in the upcomming 110.

The interresting parts I have moved over to ide.txt in Documentation.
The "inner workings" part was:
a) ehm, very very terse in style.
b) not quite revealing the reality.
I decided that it would be better to have no docu then misguiding docu.
In esp. the description of DSC handling was not adequate.
The "history of the human race" kind of documentation was certainly
not worth it, becouse: kernel release -> bandwidth consumption ->
energy production -> environmental pollution -> not good for this
planet and not of much value for the developer reading it. I checked the
contents in first place ;-). I tried to preserve credentials of course.
