2007-07-10[BATTERY] pda_power platform driverAnton Vorontsov
Common power driver for PDAs and phones with one or two external power supplies (AC/USB) connected to main and backup batteries, and optional builtin charger. It's used to stop logic duplication through different embedded devices. So, power supply *logic* is here. pda_power register power supplies, and will take care about notifying batteries about power changes through external power interface. Currently, power consumption legal limits (including USB power consumption) should be handled by platform code, inside set_charge function.

2007-07-10[S390] s390: rename CPU_IDLE to S390_CPU_IDLEHeiko Carstens
sched-cfs-v2.6.22-git-v18.patch introduces CPU_IDLE in sched.h. This conflict with the already existing define in include/asm-s390/processor.h Just rename the s390 defines, since they will go away as soon as we support CONFIG_NO_HZ instead of our own CONFIG_NO_IDLE_HZ.

After the in-kernel system call has been remove the system call path can be optimized. The problem state bit of the old psw is always set between system_call and sysc_do_svc. SAVE_ALL_SVC uses this information to avoid two instructions. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2007-07-10[S390] Program check in diag 210 under 31 bitMichael Holzheu
If a virtual address is passed to the diag210 function under 31 bit, we get a programming exception, since diag 210 only works with physical addresses. To fix this, the content of the diag210 data structure is copied to a local structure and the physical address of that structure is passed to diagnose 210.

2007-07-10[S390] Bogomips calculation for 64 bit.Martin Schwidefsky
The bogomips calculation triggered via reading from /proc/cpuinfo can return incorrect values if the qrnnd assembly is called with a pointer in %r2 with any of the upper 32 bits set. Fix this by using 64 bit division / remainder operation provided by gcc instead of calling the assembly. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2007-07-10pipe: add documentation and commentsJens Axboe
As per Andrew Mortons request, here's a set of documentation for the generic pipe_buf_operations hooks, the pipe, and pipe_buffer structures. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10pipe: change the ->pin() operation to ->confirm()Jens Axboe
The name 'pin' was badly chosen, it doesn't pin a pipe buffer in the most commonly used sense in the kernel. So change the name to 'confirm', after debating this issue with Hugh Dickins a bit. A good return from ->confirm() means that the buffer is really there, and that the contents are good. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10Remove remnants of sendfile()Jens Axboe
There are now zero users of .sendfile() in the kernel, so kill it from the file_operations structure and in do_sendfile(). Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10xip sendfile removalCarsten Otte
This patch removes xip_file_sendfile, the sendfile implementation for xip without replacement. Those customers that use xip on s390 are not using sendfile() as far as we know, and so far s390 is the only platform this could potentially be used on so far. Having sendfile is not a popular feature for execute in place file systems, however we have a working implementation of splice_read() based on fs/splice.c if anyone asks for it. At this point in time, it does not seem preferable to merge splice_read() for xip because it causes extra maintenence effort due to code duplication and it requires struct page behind the xip memory segment. We'd like to get rid of that in favor of supporting flash based embedded platforms (Monta Vista work) soon.

2007-07-10splice: completely document external interface with kerneldocJens Axboe
Also add fs/splice.c as a kerneldoc target with a smaller blurb that should be expanded to better explain the overview of splice. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10sendfile: remove bad_sendfile() from bad_file_opsJens Axboe
do_sendfile() prefers splice over sendfile, so it should not trigger (directly, at least). Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10shmem: convert to using splice instead of sendfile()Hugh Dickins
Remove shmem_file_sendfile and resurrect shmem_readpage, as used by tmpfs to support loop and sendfile in 2.4 and 2.5. Now tmpfs can support splice, loop and sendfile in the simplest way, using generic_file_splice_read and generic_file_splice_write (with the aid of shmem_prepare_write). We could make some efficiency tweaks later, if there's a real need; but this is stable and works well as is.

2007-07-10relay: use splice_to_pipe() instead of open-coding the pipe loopJens Axboe
It cleans up the relay splice implementation a lot, and gets rid of a lot of internal pipe knowledge that should not be in there. Plus fixes for padding and partial first page (and lots more) from Tom Zanussi. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10pipe: allow passing around of ops private pointerJens Axboe
relay needs this for proper consumption handling, and the network receive support needs it as well to lookup the sk_buff on pipe release. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10splice: divorce the splice structure/function definitions from the pipe headerJens Axboe
We need to move even more stuff into the header so that folks can use the splice_to_pipe() implementation instead of open-coding a lot of pipe knowledge (see relay implementation), so move to our own header file finally. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-07-10loop: convert to using splice_direct_to_actor() instead of sendfile()Jens Axboe
This gets rid of the dependency on ->sendfile() for receiving data and converts loop to ->splice_read() instead. Also includes an IV offset fix from Hugh Dickins. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-07-10sendfile: remove .sendfile from filesystems that use generic_file_sendfile()Jens Axboe
They can use generic_file_splice_read() instead. Since sys_sendfile() now prefers that, there should be no change in behaviour. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10sys_sendfile: switch to using ->splice_read, if availableJens Axboe
This patch makes sendfile prefer to use ->splice_read(), if it's available in the file_operations structure. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10vmsplice: add vmsplice-to-user supportJens Axboe
A bit of a cheat, it actually just copies the data to userspace. But this makes the interface nice and symmetric and enables people to build on splice, with room for future improvement in performance. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10splice: abstract out actor dataJens Axboe
For direct splicing (or private splicing), the output may not be a file. So abstract out the handling into a specified actor function and put the data in the splice_desc structure earlier, so we can build on top of that. This is the first step in better splice handling for drivers, and also for implementing vmsplice _to_ user memory. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-07-10Remove legacy CDROM driversJens Axboe
They are all broken beyond repair. Given that nobody has complained about them (most haven't worked in 2.6 AT ALL), remove them from the tree. A new mitsumi driver that actually works is in progress, it'll get added when completed. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-07-10[PATCH] fix request->cmd == INT casesBoaz Harrosh

2007-07-10[BLOCK] drop unnecessary bvec rewinding from flush_dry_bio_endioTejun Heo
Barrier bios are completed twice - once after the barrier write itself is done and again after the whole sequence is complete. flush_dry_bio_endio() is for the first completion. It doesn't really complete the bio. It rewinds bvec and resets bio so that it can be completed again when the whole barrier sequence is complete. The bvec rewinding code has the following problems. 1. The rewinding code is wrong because filesystems may pass bvec with non zero bv_offset. 2. The block layer doesn't guarantee anything about the state of bvec array on request completion. bv_offset and len are updated iff __end_that_request_first() completes the bvec partially. Because of #2, #1 doesn't really matter (nobody cares whether bvec is re-wound correctly or not) but then again by not doing unwinding at all, we'll always give back the same bvec to the caller as full bvec completion doesn't alter bvecs and the final completion is always full completion. Drop unnecessary rewinding code. This is spotted by Neil Brown. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Neil Brown <neilb@suse.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
