| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally the FPGA ID checking switch statement left disabled all the TS implemented FPGA devices if the ID was unknown to it. Michael Spang created a fix in f9b1184e that changed the default to enable the devices in the event TS silently release more revisions into the wild, this unfortunately breaks custom FPGA bitstreams. This patch amends the switch statement so that the TS devices are only enabled if on the revision number is unknown (whilst the magic matches).

* [ARM] orion5x: Set links to solid on D-Link DNS-323Martin Michlmayr2010-07-171-2/+1
| | | | | | | | | | | | | | | Among other changes, commit b2a731aa ("D-link DNS-323 revision A1 power LED") changed the default behaviour of the power LED from solid to blinking. This was done to match the original DNS-323 firmware which blinks during the boot process and sets the LED to solid when booting has completed. However, the downside of this behaviour is that it requires userland code to change the LED, even for those who don't care about the behaviour of the original firmware. Therefore, change it to solid again and let those who care about the original behaviour change the behaviour from userland.

* leds: leds-gpio: Change blink_set callback to be able to turn off blinkingBenjamin Herrenschmidt2010-05-261-10/+12
| | | | | | | | | | | | | | | | | | | The leds-gpio blink_set() callback follows the same prototype as the main leds subsystem blink_set() one. The problem is that to stop blink, normally, a leds driver does it in the brightness_set() callback when asked to set a new fixed value. However, with leds-gpio, the platform has no hook to do so, as this later callback results in a standard GPIO manipulation. This changes the leds-gpio specific callback to take a new argument that indicates whether the LED should be blinking or not and in what state it should be set if not. We also update the dns323 platform which seems to be the only user of this so far.

* [ARM] dns323-setup.c: fix WARN() when bootingArnaud Patard2010-05-031-0/+1
| | | | | | | | | | | | | Since commit b2a731aa5cbca7e0252da75e16de7ae5feb1313a, dns323_init() is setting the power led gpio direction with gpio_direction_output() but doesn't request the gpio before (which is not permitted by the gpio layer afaik). This behaviour is triggering a WARN() at boot time.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
