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

2010-03-13x86, k8 nb: Fix boot crash: enable k8_northbridges unconditionally on AMD ↵Borislav Petkov
systems de957628ce7c84764ff41331111036b3ae5bad0f changed setting of the x86_init.iommu.iommu_init function ptr only when GART IOMMU is found. One side effect of it is that num_k8_northbridges is not initialized anymore if not explicitly called. This resulted in uninitialized pointers in <arch/x86/kernel/cpu/intel_cacheinfo.c:amd_calc_l3_indices()>, for example, which uses the num_k8_northbridges thing through node_to_k8_nb_misc(). Fix that through an initcall that runs right after the PCI subsystem and does all the scanning. Then, remove initialization in gart_iommu_init() which is a rootfs_initcall and we're running before that. What is more, since num_k8_northbridges is being used in other places beside GART IOMMU, include it whenever we add AMD CPU support. The previous dependency chain in kconfig contained K8_NB depends on AGP_AMD64|GART_IOMMU which was clearly incorrect. The more natural way in terms of hardware dependency should be AGP_AMD64|GART_IOMMU depends on K8_NB depends on CPU_SUP_AMD && PCI. Make it so Number One!

The above commit changes agp_amd64_init() not to do anything if gart_iommu_aperture is not zero. If GART iommu calls agp_amd64_init(), we need to skip agp_amd64_init() when it's called later via module_init. The problem is that gart_iommu_init() calls agp_amd64_init() with not zero gart_iommu_aperture so agp_amd64_init() is never initialized. When gart_iommu_init() calls agp_amd64_init(), agp should be always initialized.

Commit 15b8dd53f5ffa changed the string in info->hardware_id from a static array to a pointer and added a length field. But instead of changing "sizeof(array)" to "length", we changed it to "sizeof(length)" (== 4), which corrupts the string we're trying to null-terminate. We no longer even need to null-terminate the string, but we *do* need to check whether we found a HID. If there's no HID, we used to have an empty array, but now we have a null pointer.

2009-12-07agp/intel-agp: Clear entire GTT on startupDavid Woodhouse
Some BIOSes fail to initialise the GTT, which will cause DMA faults when the IOMMU is enabled. We need to clear the whole thing to point at the scratch page, not just the part that Linux is going to use.

2009-09-22mm: replace various uses of num_physpages by totalram_pagesJan Beulich
Sizing of memory allocations shouldn't depend on the number of physical pages found in a system, as that generally includes (perhaps a huge amount of) non-RAM pages. The amount of what actually is usable as storage should instead be used as a basis here. Some of the calculations (i.e. those not intending to use high memory) should likely even use (totalram_pages - totalhigh_pages).
