2007-10-17PNP: don't fail device init if no DMA channel availableJan Beulich
Most drivers for devices supporting ISA DMA can operate without DMA as well (falling back zo PIO). Thus it seems inappropriate for PNP to fail device initialization in case none of the possible DMA channels are available. Instead, it should be left to the driver to decide what to do if request_dma() fails. The patch at once adjusts the code to account for the fact that pnp_assign_dma() now doesn't need to report failure anymore.

2007-10-17floppy: remove register keyword use from floppy driverJesper Juhl
The floppy drive is slow. These days I see absolutely no good reason why the floppy driver should try to gain a tiny bit of speed by telling gcc to optimize access to some variables via the register keyword. Better to just leave gcc free to do whatever optimizations it deduces to be sane and not hamper it by telling it that some variables in the floppy driver are special and need to be fast (they don't).

2007-10-17md: expose the degraded status of an assembled array through sysfsIustin Pop
The 'degraded' attribute is useful to quickly determine if the array is degraded, instead of parsing 'mdadm -D' output or relying on the other techniques (number of working devices against number of defined devices, etc.). The md code already keeps track of this attribute, so it's useful to export it.

2007-10-17md: 'sync_action' in sysfs returns wrong value for readonly arraysNeilBrown
When an array is started read-only, MD_RECOVERY_NEEDED can be set but no recovery will be running. This causes 'sync_action' to report the wrong value. We could remove the test for MD_RECOVERY_NEEDED, but doing so would leave a small gap after requesting a sync action, where 'sync_action' would still report the old value. So make sure that for a read-only array, 'sync_action' always returns 'idle'.

2007-10-17md: software Raid autodetect dev list not arrayMichael J. Evans
In current release kernels the md module (Software RAID) uses a static array (dev_t[128]) to store partition/device info temporarily for autostart. I discovered this (and that the devices are added as disks/partitions are discovered at boot) while I was debugging why only one of my MD arrays would come up whole, while all the others were short a disk. I eventually discovered that it was enumerating through all of 9 of my 11 hds (2 had only 4 partitions apiece) while the other 9 have 15 partitions (I wanted 64 per drive...). The last partition of the 8th drive in my 9 drive raid 5 sets wasn't added, thus making the final md array short both a parity and data disk, and it was started later, elsewhere. This patch replaces that static array with a list. [akpm@linux-foundation.org: removed unused var] Signed-off-by: Michael J.

2007-10-17tty: expose new methods needed for drivers to get termios rightAlan Cox
This adds three new functions (or in one case to be more exact makes it always available) tty_termios_copy_hw Copies all the hardware settings from one termios structure to the other. This is intended for drivers that support little or no hardware setting tty_termios_encode_baud_rate Allows you to set the input and output baud rate in a termios structure. A driver is supposed to set the resulting baud rate from a request so most will want to use this function to set the resulting input and output rates to match the hardware values. Internally it knows about keeping Bxxx encoding when possible to maximise compatibility. tty_encode_baud_rate As above but for the tty's own current termios structure I suspect this will initially need some tweaking as it gets enabled by driver patches over the next few mm cycles so consider this lot -mm only for the moment so it can stabilize and end up neat before it goes to base. I've tried not to break any obscure architectures - if you get a speed you can't represent the code will print warnings on non updated termios systems but not break. Once this is merged and seems sane I've got a growing pile of driver updates to use it - notably for USB serial drivers.

Remove the old-fashioned lk201 driver under drivers/tc/ that used to be used by the old dz.c and zs.c drivers, which is now orphan code referred to from nowhere and does not build anymore. A modern replacement is available as drivers/input/keyboard/lkkbd.c. There are no plans to do anything about this piece of code and it does not fit anywhere anymore, so it is not just a matter of maintenance or the lack of. There are still some bits that might be added to the new lkkbd.c driver based on the old code, and the embedded hardware documentation which is otherwise quite hard to get hold of might be useful to keep too.

For the SG_IO ioctl, this was not sufficient, and we noticed that, for example, sg_turs from sg3_utils did not correctly detect problems due to cciss having set rq->errors incorrectly.

2007-10-17NBD: allow hung network I/O to be cancelledPaul Clements
Allow NBD I/O to be cancelled when a network outage occurs. Previously, I/O would just hang, and if enough I/O was hung in nbd, the system (at least user-level) would completely hang until a TCP timeout (default, 15 minutes) occurred. The patch introduces a new ioctl NBD_SET_TIMEOUT that allows a transmit timeout value (in seconds) to be specified. Any network send that exceeds the timeout will be cancelled and the nbd connection will be shut down. I've tested with various timeout values and 6 seconds seems to be a good choice for the timeout. If the NBD_SET_TIMEOUT ioctl is not called, you get the old (I/O hang) behavior.

2007-10-17aoe: remove unecessary wrapper functionEd L. Cashin
We can just use skb_mac_header now, and we don't need a wrapper function to perform the cast. Instead of requiring the reader to check aoe.h to look up what an aoe_hdr function does, I'd rather do without it.

2007-10-17pnp: avoid a small unlikely memory leak in proc_read_escd()Jesper Juhl
There's a small and unlikely memory leak in drivers/pnp/pnpbios/proc.c::proc_read_escd(). It's inside a sanity check, so it probably won't trigger often (if at all), however it *is* a potential leak and it's easy to avoid, so let's just fix it :) Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-10-17Tweak /proc/ipmi removalAlexey Dobriyan
Driver does proc_mkdir("ipmi", NULL); but remove_proc_entry(proc_ipmi_root->name, &proc_root); This is OK and working if only slightly inconsistent. Also changing proc_root to NULL will help OpenVZ which has multiple proc roots and, as we now know, requires matching parents in such cases.

2007-10-17tpm: pay attention to IRQ info from PNPBjorn Helgaas
If we discover the TIS TPM device via PNP, use the PNP IRQ information rather than probing for an IRQ. If PNP shows no IRQ, run the TPM in polling mode.

2007-10-17Remove "unsafe" from module structRusty Russell
Adrian Bunk points out that "unsafe" was used to mark modules touched by the deprecated MOD_INC_USE_COUNT interface, which has long gone. It's time to remove the member from the module structure, as well. If you want a module which can't unload, don't register an exit function. (Vlad Yasevich says SCTP is now safe to unload, so just remove the __unsafe there).

2007-10-17convert ill defined log2() to ilog2()Fengguang Wu
It's *wrong* to have #define log2(n) ffz(~(n)) It should be *reversed*: #define log2(n) flz(~(n)) or #define log2(n) fls(n) or just use ilog2(n) defined in linux/log2.h. This patch follows the last solution, recommended by Andrew Morton.
