* mtd: Add export.h for EXPORT_SYMBOL/THIS_MODULE where neededPaul Gortmaker2011-10-314-0/+4
| | | | | | | These two common macros will be no longer present everywhere. Call out the include needs of them explicitly where required. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* crypto: add module.h to those files that are explicitly using itPaul Gortmaker2011-10-311-0/+1
| | | | | | | | Part of the include cleanups means that the implicit inclusion of module.h via device.h is going away. So fix things up in advance. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* drivers/net: fix mislocated headers in cxgb4/l2t.cPaul Gortmaker2011-10-311-4/+3
| | | | | | | | | | For some reason three #include <linux/...> are buried way down in the file. Since the inclusion of module.h is one of them, the inclusion comes after use of EXPORT_SYMBOL which will cause warnings about implicit declarations. Relocate all the headers to the top.

* drivers/net: wireless/ath/ath5k/debug.c does not need module.hPaul Gortmaker2011-10-311-1/+0
| | | | | | | | | It only has module_param and EXPORT_SYMBOL, so now that export.h is in scope at the same time as the recent ath5k update, we can delete this module.h include. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* drivers/net: Add moduleparam.h to drivers as required.Paul Gortmaker2011-10-3110-0/+11
| | | | | | | | These files were using moduleparam infrastructure, but were not including anything for it -- which is fine when module.h is being implicitly included in all files, but that is going away. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

* drivers/net: Add export.h to files using EXPORT_SYMBOL/THIS_MODULEPaul Gortmaker2011-10-3166-0/+66
| | | | | | | | | | | | | | | These were getting the macros from an implicit module.h include via device.h, but we are planning to clean that up. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> drivers/net: Add export.h to wireless/brcm80211/brcmfmac/bcmsdh.c This relatively recently added file uses EXPORT_SYMBOL and hence needs export.h included so that it is compatible with the module.h split up work.

* drivers/net: Add module.h to drivers who were implicitly using itPaul Gortmaker2011-10-3146-0/+46
| | | | | | | | The device.h header was including module.h, making it present for most of these drivers. But we want to clean that up. Call out the include of module.h in the modular network drivers. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

| | | | | | | | We want to clean up the implicit everywhere presence of module.h which means files like this that use module infrastructure need to explicitly call it out for inclusion. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* parisc: Add export.h to files needing EXPORT_SYMBOL/THIS_MODULEPaul Gortmaker2011-10-311-0/+1

* s390: add missing module.h/export.h includesHeiko Carstens2011-10-3113-0/+15
| | | | | | | | | | | | | Fix several compile errors on s390 caused by splitting module.h. Some include additions [e.g. qdio_setup.c, zfcp_qdio.c] are in anticipation of pending changes queued for s390 that increase the modular use footprint.

* powerpc: Fix up modules that should be including module.hPaul Gortmaker2011-10-311-0/+1
| | | | | | | So that we can clean up the header files and not be relying on implicit includes from device.h ---> module.h Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* powerpc: add export.h to files making use of EXPORT_SYMBOLPaul Gortmaker2011-10-311-0/+1
| | | | | | | | | With module.h being implicitly everywhere via device.h, the absence of explicitly including something for EXPORT_SYMBOL went unnoticed. Since we are heading to fix things up and clean module.h from the device.h file, we need to explicitly include these files now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* x86: fix up files really needing to include module.hPaul Gortmaker2011-10-315-0/+5

* acpi: add export.h to files using THIS_MODULE/EXPORT_SYMBOLPaul Gortmaker2011-10-3122-0/+22
| | | | | | | | | These files were relying on module.h to come in via the path in an include/acpi header file, but we don't want to have instances of module.h being included from include/* files if it can be avoided. Have the files include export.h instead. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* acpi: downgrade files from module.h to export.h where possible.Paul Gortmaker2011-10-311-1/+1
| | | | | | | | | If a file is only exporting symbols and not using the core modular infrastructure, it can get by with just including the smaller export.h header, which is a lot smaller than the module.h header. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* acpi: delete module.h include from files explicitly not needing itPaul Gortmaker2011-10-311-1/+0
| | | | | | | | Files which aren't actually using infrastructure from module.h shouldn't include it, as it is a big header with lots of child includes spawned off. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* acpi: add module.h to files implicitly using/relying on it.Paul Gortmaker2011-10-313-0/+3

| | | | | | | | | | | | | | | | | | | | | | | | | | Always failing to register I2C buses when the line testing fails is a little harsh. While such a failure is definitely a bug in the driver that exposes the affected I2C bus, things may still work fine if the missing initialization steps are done later, before the I2C bus is used. So it seems a better debugging tool to just report the test failure by default. I introduce bit_test=2 if anyone really misses the original behavior of bit_test=1.

These are however only there when the debug code is built as a module. Since it is possible to build the debug code into the kernel, the functions should also be provided for the built-in case.

But the omap iommu driver is not compiled without IOMMU_SUPPORT enabled. Fix that by forcing OMAP_IOMMU and OMAP_IOVMM are enabled before VIDEO_OMAP3 can be selected.

Fix omap_iommu_unmap() to do so and adopt omap-iovmm accordingly. Signed-off-by: Ohad Ben-Cohen <ohad@wizery.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
