Currently, "disable_clkrun" yenta_socket module parameter is only implemented for TI CardBus bridges. Add also an implementation for Ricoh bridges that have the necessary setting documented in publicly available datasheets. Tested on a RL5C476II with a Sunrich C-160 CardBus NIC that doesn't work correctly unless the CLKRUN protocol is disabled.

These interfaces: pcibios_resource_to_bus(struct pci_dev *dev, *bus_region, *resource) pcibios_bus_to_resource(struct pci_dev *dev, *resource, *bus_region) took a pci_dev, but they really depend only on the pci_bus. And we want to use them in resource allocation paths where we have the bus but not a device, so this patch converts them to take the pci_bus instead of the pci_dev: pcibios_resource_to_bus(struct pci_bus *bus, *bus_region, *resource) pcibios_bus_to_resource(struct pci_bus *bus, *resource, *bus_region) In fact, with standard PCI-PCI bridges, they only depend on the host bridge, because that's the only place address translation occurs, but we aren't going that far yet.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+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.

2009-12-08pcmcia: CodingStyle fixesDominik Brodowski1-51/+96
Fix several CodingStyle issues in drivers/pcmcia/ . checkpatch.pl no longer reports errors in the PCMCIA core. The remaining warnings mostly relate to wrong indent -- PCMCIA historically used 4 spaces --, to lines over 80 characters and to hundreds of typedefs. The cleanup of those will follow in the future.

2009-11-03PM / yenta: Split resume into early and late parts (rev. 4)Rafael J. Wysocki1-1/+11
Commit 0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c (PM / yenta: Fix cardbus suspend/resume regression) caused resume to fail on systems with two CardBus bridges. While the exact nature of the failure is not known at the moment, it can be worked around by splitting the yenta resume into an early part, executed during the early phase of resume, that will only resume the socket and power it up if there was a card in it during suspend, and a late part, executed during "regular" resume, that will carry out all of the remaining yenta resume operations. Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14334, which is a listed regression from 2.6.31. Signed-off-by: Rafael J.

2009-09-29PM / yenta: Fix cardbus suspend/resume regressionRafael J. Wysocki1-40/+48
Since 2.6.29 the PCI PM core have been restoring the standard configuration registers of PCI devices in the early phase of resume. In particular, PCI devices without drivers have been handled this way since commit 355a72d75b3b4f4877db4c9070c798238028ecb5 (PCI: Rework default handling of suspend and resume). Unfortunately, this leads to post-resume problems with CardBus devices which cannot be accessed in the early phase of resume, because the sockets they are on have not been woken up yet at that point. To solve this problem, move the yenta socket resume to the early phase of resume and, analogously, move the suspend of it to the late phase of suspend. Additionally, remove some unnecessary PCI code from the yenta socket's resume routine. Fixes http://bugzilla.kernel.org/show_bug.cgi?id=13092, which is a post-2.6.28 regression.

2009-09-29PM / PCMCIA: Drop second argument of pcmcia_socket_dev_suspend()Rafael J. Wysocki1-1/+1
pcmcia_socket_dev_suspend() doesn't use its second argument, so it may be dropped safely. This change is necessary for the subsequent yenta suspend/resume fix. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Cc: stable@kernel.org
2009-09-22pcmcia: yenta: add missing __devexit markingMike Frysinger1-1/+1
The remove member of the pci_driver yenta_cardbus_driver uses __devexit_p(), so the remove function itself should be marked with __devexit. Even more so considering the probe function is marked with __devinit.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
