The Linux driver doesn't keep a pending queue as the old one did. so we can remove all the code related to it. Signed-off-by:

The NMI code is in the shipped driver for "validation". We won't be doing chip validation and we have proper core nmi handling so this can go. Signed-off-by:

The definition of slic_netdev_ops has initializations of a local function and eth_mac_addr for its ndo_set_mac_address field. This change uses only the local function. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier I, s, fld; position p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @s@ identifier I, s, r.fld; position r.p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @script:python@ p0 << r.p0; fld << r.fld; ps << s.p; pr << r.p; @@ if int(ps[0].line)!=int(pr[0].line) or int(ps[0].column)!=int(pr[0].column): cocci.print_main(fld,p0) // </smpl> Signed-off-by:

Both the max1363 and lis3l02dq modules rely on IIO trigger support in their ring buffer implementations, which is presently a separate config option. In the case of IIO_RING_BUFFER=y and IIO_TRIGGER=n, we end up with the following: ERROR: "iio_trigger_attach_poll_func" [drivers/staging/iio/adc/max1363.ko] undefined!

Fix iio header files kernel-doc notation errors, spelling, typos, indentation, grammar, etc. It would also be good if these function names were spelled correctly, but I didn't change them: iio_push_or_escallate_ring_event() iio_trigger_dettach_poll_func() Signed-off-by:

Short guide on how to setup and use ramzswap. Signed-off-by:

Nitin Gupta authored
Creates RAM based block devices (/dev/ramzswapX) which can be used (only) as swap disks. Pages swapped to these are compressed and stored in memory itself. The module is called ramzswap.ko. It depends on: - xvmalloc memory allocator (compiled with this driver) - lzo_compress.ko - lzo_decompress.ko See ramzswap.txt for usage details. Signed-off-by:

* Features: - Low metadata overhead (just 4 bytes per object) - O(1) Alloc/Free - except when we have to call system page allocator to get additional memory. - Very low fragmentation: In all tests, xvmalloc memory usage is within 12% of "Ideal". - Pool based allocator: Each pool can grow and shrink. - It maps pages only when required. So, it does not hog vmalloc area which is very small on 32-bit systems. SLUB allocator could not be used due to fragmentation issues: http://code.google.com/p/compcache/wiki/AllocatorsComparison Data here shows kmalloc using ~43% more memory than TLSF and xvMalloc is showed ~2% more space efficiency than TLSF (due to smaller metadata). Creating various kmem_caches can reduce space efficiency gap but still problem of being limited to low memory exists. Also, it depends on allocating higher order pages to reduce fragmentation - this is not acceptable for ramzswap as it is used under memory crunch (its a swap device!). SLOB allocator could not be used do to reasons mentioned here: http://lkml.org/lkml/2009/3/18/210 * Implementation: It uses two-level bitmap search to find free list containing block of correct size. This idea is taken from TLSF (Two-Level Segregate Fit) allocator and is well explained in its paper (see [Links] below). * Limitations: - Poor scalability: No per-cpu data structures (work in progress).

The i8253_cascade_ns_to_timer_2div() function (and i8253_cascade_ns_to_timer macro) checks the old values *d1 and *d2 for correctness as a heuristic before calculating new values. Don't call the function with uninitialized values in *d1 and *d2. Signed-off-by:

512 bytes of stack can be saved in serial_2002_open() by modifying 'struct config_t'. A short int suffices for the 'kind' and 'bits' members. (Actually, a char would suffice, but wouldn't save any more stack than a short int.) Signed-off-by:

I've fixed a bug in the USBDUX driver which caused timeouts while sending commands to the boards. This was mainly because of one bulk transfer which had a timeout of 1ms (!). I've now set all timeouts to 1000ms. From: Bernd Porr <BerndPorr@f2s.com> Signed-off-by: -
