Add control of fan minimum turn-on output levels, decoupling it from the fan turn-off output level. Add control of rate of change of fan output level. These in turn allow lower turn-off rotor speed and smoother transitions for better thermal and acoustic control authority. Add support for constant fan speed and proportional-response operations modes. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

This new revision of the IP adds some improvements to the MCI already present in several Atmel SOC. Some new registers are added and a particular way of handling DMA interaction lead to a new sequence in function call which is backward compatible: On MCI2, we must set the DMAEN bit to enable the DMA handshaking interface. This must happen before the data transfer command is sent. A new function is able to differentiate MCI2 code and is based on knowledge of processor id (cpu_is_xxx()). Signed-off-by:

Allow the use of another DMA controller driver in atmel-mci sd/mmc driver. This adds a generic dma_slave pointer to the mci platform structure where we can store DMA controller information. In atmel-mci we use information provided by this structure to initialize the driver (with new helper functions that are architecture dependant). This also adds at32/avr32 chip modifications to cope with this new access method. Signed-off-by:

Some people run general-purpose distribution kernels on netbooks with a card that is physically non-removable or logically non-removable (e.g. used for /home) and cannot be cleanly unmounted during suspend. Add a module parameter to set whether cards are assumed removable or non-removable, with the default set by CONFIG_MMC_UNSAFE_RESUME. In general, it is not possible to tell whether a card present in an MMC slot after resume is the same that was there before suspend. So there are two possible behaviours, each of which will cause data loss in some cases: CONFIG_MMC_UNSAFE_RESUME=n (default): Cards are assumed to be removed during suspend. Any filesystem on them must be unmounted before suspend; otherwise, buffered writes will be lost. CONFIG_MMC_UNSAFE_RESUME=y: Cards are assumed to remain present during suspend. They must not be swapped during suspend; otherwise, buffered writes will be flushed to the wrong card. Currently the choice is made at compile time and this allows that to be overridden at module load time. Signed-off-by:

Currently DaVinci EDMA driver supports multiple EDMA channel controller instances. edma_alloc_channel() api returns a 32 bit value which has the channel controller number in MSB and the EDMA channel number in LSB. The variables which store the value returned by edma_alloc_channel() have to be 32 bit wide now. Signed-off-by:

Rework the current CIS tuple parsing code, reusing the existing infrastructure and providing an easy way to add new CISTPL_FUNCE parsers by TPLFE_TYPE. Valid known CIS tuples are now silently queued for the SDIO function driver when not parsed/processed (-EILSEQ) by the SDIO core. Unknown CIS tuples (-ENOENT) are queued too for the SDIO function driver without aborting the initialization, but emit a warning in the kernel log. CISTPL_FUNCE tuples can be "whitelisted" now by adding a matching entry to the cis_tpl_funce_list table. Signed-off-by:

Rather than have the EDD depend on !ia64 (and assuming that only ia64, x86, x86_64 will be including this Kconfig), have EDD depend on the only arches which can support this code. This should allow all other arches to cleanly include the firmware Kconfig. Also simplify the x86 string used by FIRMWARE_MEMMAP to match EDD. Signed-off-by:

Recently, We marked strstrip() as must_check. because it was frequently misused and it should be checked. However, we found one exception. scsi/ipr.c intentionally ignore return value of strstrip. Because it wishes to keep the whitespace at the beginning. Thus we need to keep with and without checked whitespace trim function. This patch adds a new strim() and changes ipr.c to use it.

Makes use of skip_spaces() defined in lib/string.c for removing leading spaces from strings all over the tree. It decreases lib.a code size by 47 bytes and reuses the function tree-wide: text data bss dec hex filename 64688 584 592 65864 10148 (TOTALS-BEFORE) 64641 584 592 65817 10119 (TOTALS-AFTER) Also, while at it, if we see (*str && isspace(*str)), we can be sure to remove the first condition (*str) as the second one (isspace(*str)) also evaluates to 0 whenever *str == 0, making it redundant. In other words, "a char equals zero is never a space". Julia Lawall tried the semantic patch (http://coccinelle.lip6.fr) below, and found occurrences of this pattern on 3 more files: drivers/leds/led-class.c drivers/leds/ledtrig-timer.c drivers/video/output.c @@ expression str; @@ ( // ignore skip_spaces cases while (*str && isspace(*str)) { \(str++;\|++str;\) } | - *str && isspace(*str) ) Signed-off-by:

André Goddard Rosa authored
On the following sentence: while (*s && isspace(*s)) s++; If *s == 0, isspace() evaluates to ((_ctype[*s] & 0x20) != 0), which evaluates to ((0x08 & 0x20) != 0) which equals to 0 as well. If *s == 1, we depend on isspace() result anyway. In other words, "a char equals zero is never a space", so remove this check. Also, *s != 0 is most common case (non-null string). Fixed const return as noticed by Jan Engelhardt and James Bottomley. Fixed unnecessary extra cast on strstrip() as noticed by Jan Engelhardt. Signed-off-by: -

The difference between simple_strtoul() and simple_strtoull() is just the size of the variable used to keep track of the sum of characters converted to numbers: unsigned long simple_strtoul() {...} unsigned long long simple_strtoull(){...} Both are same size on my Core 2/gcc 4.4.1. Overflow condition is not checked on both functions, so an extremely large string can break these functions so that they don't even notice it. As we do not care for overflowing on these functions, always keep the sum using the larger variable around (unsigned long long) on simple_strtoull() and cast it to (unsigned long) on simple_strtoul(), which then becomes just a wrapper around simple_strtoull().
