[PATCH] PPC64: large INITRD causes kernel not to boot
In PPC64 there are number of problems in arch/ppc64/boot/main.c that
prevent a kernel from making use of a large (greater than ~16MB) INITRD.
This is 64 bit architecture and really large INITRD images should be
possible.
Simply put the existing code has a fixed reservation (claim) address and
once the kernel plus initrd image are large enough to pass this address
all sorts of bad things occur. The fix is the dynamically establish the
first claim address above the loaded kernel plus initrd (plus some
"padding" and rounding). If PROG_START is defined this will be used as
the minimum safe address - currently known to be 0x01400000 for the

This starts to prepare the core of "usbnet" to know less about various
framing protocols that map Ethernet packets onto USB, so "minidrivers"

- Remove some framing-specific code that cluttered the core:
* net->hard_header_len records how much space to preallocate;
now drivers that add their own framing (Net1080, GeneLink,
Zaurus, and RNDIS) will have smoother TX paths. Even for
the drivers (Zaurus, Net1080) that need trailers.
* defines new dev->hard_mtu, using this "hardware" limit to
check changes to the link's settable "software" mtu.
* now net->hard_header_len and dev->hard_mtu are set up in the
driver bind() routines, if needed.
- Transaction ID is no longer specific to the Net1080 framing;
RNDIS needs one too.
- Creates a new "usbnet.h" header with declarations that are shared
between the core and what will be separate modules.
- Plus a couple other minor tweaks, like recognizing -ESHUTDOWN
means the keventd work should just shut itself down asap.
The core code is only about 1/3 of this large file. Splitting out the
minidrivers into separate modules (e.g. ones for ASIX adapters,
Zaurii and similar, CDC Ethernet, etc), in later patches, will

[PATCH] USB: ub 4: Zaitcev's quasi-S/G
Back out Axboe-style quasi-S/G and replace it with one command and
repeated URBs. This is similar to what usb-storage does, only instead
of a few URBs allocated together, one URB is reused.
Jens's idea was very nice, but it collapsed when I had to support
packet commads for CD burning. I cannot issue two or more packet
commands where application expected only one.
However, burning does not work completely yet. The cdrecord starts,
recognizes the device, then aborts without writing a TOC.

[PATCH] USB: ub 3/3: death to ub_bd_rq_fn_1
When Al Viro saw the ub.c, he observed that it was a proof positive of
Linus not reading patches anymore: names like fo_ob_ar_ba_2 used to
cause serious fireworks. In my defence, any good scheme can be pushed
to the realm of absurd if pushed far enough.

[PATCH] USB: ub 1/3: Axboe's quasi-S/G
This the quasi-S/G patch for ub as suggested by Jens Axboe at OLS and
implemented that night before 4 a.m. Surprisingly, it worked right away...
Alas, I had to skip some OLS partying, but it was for the good cause.
Now the speed of ub is quite acceptable even on partitions with small
block size.
The ub does not really support S/G. Instead, it just tells the block
layer that it does. Then, most of the time, the block layer merges
requests and passes single-segmnent requests down to ub; everything
works as before. Very rarely ub gets an unmerged S/G request. In such
case, it issues several commands to the device.
I added a small array of counters to monitor the merging (sg_stat).
This may be dropped later.

[PATCH] usb-storage: Add IGNORE_RESIDUE flag for Mitsumi USB 2.0 card reader (VIA hardware)
This patch adds an entry in the unusual_devs.h file for a Mitsumi card
reader/floppy combo that uses a VIA chipset. The IGNORE_RESIDUE flag was
needed for the second LUN to operate properly.

[PATCH] USB: Fix regression in core/devio.c
This patch (as551) fixes another little problem recently added to the
USB core. Someone didn't fix the type of the first argument to
unregister_chrdev_region.

This makes libusb pick up the real nodes instead of the mounted usbfs:
export USB_DEVFS_PATH=/dev/bus/usb
Background:
All this makes it possible to manage usb devices with udev instead of
the devfs solution. We are currently working on a pam_console/resmgr
replacement driven by udev and a pam-helper. It applies ACL's to device
nodes, which is required for modern desktop functionalty like
"Fast User Switching" or multiple local login support.
New patch with its own major. I've succesfully disabled usbfs and use real
nodes only on my box. With: "export USB_DEVFS_PATH=/dev/bus/usb" libusb picks
up the udev managed nodes instead of reading usbfs files.
This makes udev to provide symlinks for libusb to pick up:
SUBSYSTEM="usb_device", PROGRAM="/sbin/usbdevice %k", SYMLINK="%c"
