| | | | | | | | | | | | | | | | | | Assert that userspace suspend and resume requests appearing (almost) immediately are executed in the following order: suspend, resume. This should result in "pccardctl reset" behaving the same as before. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
| * pcmcia: avoid pccard_validate_cis failure in resume callpathDominik Brodowski2010-05-03
| | | | | | | | | | | | | | | | | | | | If the PCMCIA CIS changed before a resume event (e.g. due to a card exchange while being suspended, possibly also during a call to "pccardctl reset"), also set the function count to zero so that the subsequent call to pccard_validate_cis() does not fail.

* | MIPS: DB1200: PCMCIA card detection must not be auto-enabled.Manuel Lauss2010-04-30
|/ | | | | | | | | | | | | | | Same issues as SD card detection: One of both is always triggering and the handlers take care to shut it up and enable the other. To avoid messages about "unbalanced interrupt enable/disable" they must not be automatically enabled when initally requested. This was not an issue with the db1200_defconfig due to fortunate timings; on a build without network chip support the warnings appear.

| | | | | | | | | pcmcia_dev_present is in and by itself buggy.

* pcmcia: avoid late calls to pccard_validate_cisDominik Brodowski2010-04-17
| | | | | | | | | pccard_validate_cis() nowadays destroys the CIS cache. Therefore, calling it after card setup should be avoided. We can't control the deprecated PCMCIA ioctl (which is only used on ARM nowadays), but we can avoid -- and report -- any other calls. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

* | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | MIPS: Alchemy: use 36bit addresses for PCMCIA resources.Manuel Lauss2010-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Alchemy the PCMCIA area lies at the end of the chips 36bit system bus area. Currently, addresses at the far end of the 32bit area are assumed to belong to the PCMCIA area and fixed up to the real 36bit address before being passed to ioremap(). A previous commit enabled 64 bit physical size for the resource datatype on Alchemy and this allows to use the correct 36bit addresses when registering the PCMCIA sockets. This patch removes the 32-to-36bit address fixup and registers the Alchemy demo board pcmcia socket with the correct 36bit physical addresses. Tested on DB1200, with a CF card (ide-cs driver) and a 3c589 PCMCIA ethernet card.

| * | MIPS: PCMCIA: new socket driver for Au1000 demoboards.Manuel Lauss2010-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New PCMCIA socket driver for all Db/Pb1xxx boards (except Pb1000), which replaces au1000_db1x00.c and (most of) au1000_pb1x00.c. Notable improvements: - supports Db1000, DB/PB1100/1500/1550/1200. - support for carddetect and statuschange IRQs. - pcmcia socket mem/io/attr areas and irqs passed through platform resource information. - doesn't freeze system during card insertion/ejection like the one it replaces. - boardtype is automatically detected using BCSR ID register. Run-tested on the DB1200. Cc: Linux-PCMCIA <linux-pcmcia@lists.infradead.org> Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
| * | MIPS: Alchemy: devboard register abstractionManuel Lauss2010-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All Alchemy development boards have external CPLDs with a few registers in them. They all share an identical register layout with only a few minor differences (except the PB1000) in bit functions and base addresses. This patch - adds a primitive facility to initialize and use these external registers, - replaces all occurrences of bcsr->xxx accesses with calls to the new functions (the pb1200 cascade irq handling code is special). - collects BCSR register information scattered throughout the board headers in a central place.

| * | pcmcia: validate late-added resourcesDominik Brodowski2010-02-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, only those mem resources are validated which are already registered at the time the first PCMCIA card is inserted. As we can only validate resources immediately after card insert, store "registered" mem resources in mem_db, and only upon validation move them to mem_db_valid. When allocationg mem resources, mem_db_valid is then preferred to mem_db. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
