* [PATCH] gfp_t: fs/*Al Viro2005-10-286-7/+7
| | | | | | | | | | | | | | | | | | | - ->releasepage() annotated (s/int/gfp_t), instances updated - missing gfp_t in fs/* added - fixed misannotation from the original sweep caught by bitwise checks: XFS used __nocast both for gfp_t and for flags used by XFS allocator. The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.

There are still some places where asm/bitops.h is directly included, but I think that code should be fixed. I was a little wary of the patch for this reason but lubbock, mainstone and assabet all build OK and so do my in house boards... ARM is the only arch with the generic_fls prototype in this way.

There's no way to destroy this cache, so when we discard an overall idr tree we end up leaking some memory. Add and use idr_destroy() for this. v9fs and infiniband also need to use idr_destroy() to avoid leaks. Or, we make the cache global, like radix_tree_preload(). Which is probably better. Later.

We also introduce alloc_bootmem_low_pages_limit, alloc_bootmem_node_limit, alloc_bootmem_low_pages_node_limit apis, but alloc_bootmem_low_pages_limit is the only api used for swiotlb. The existing alloc_bootmem_low_pages() api could instead have been changed and made to pass right limit to the core allocator. But that would make the patch more intrusive for 2.6.14, as other arches use alloc_bootmem_low_pages(). We may be done that post 2.6.14 as a cleanup. With this, swiotlb gets memory within 4G for both x86_64 and ia64 arches.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hugetlb pages are currently pre-faulted. At the time of mmap of hugepages, we populate the new PTEs. It is possible that HW has already cached some of the unused PTEs internally. These stale entries never get a chance to be purged in existing control flow. This patch extends the check in page fault code for hugepages. Check if a faulted address falls with in size for the hugetlb file backing it. We return VM_FAULT_MINOR for these cases (assuming that the arch specific page-faulting code purges the stale entry for the archs that need it).
