2008-12-18x86: PAT: update documentation to cover pgprot and remap_pfn related changes ↵venkatesh.pallipadi@intel.com
- v3 Impact: Documentation only. Add documentation related to pgprot_* change. Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2008-12-18x86: PAT: add pgprot_writecombine() interface for drivers - v3venkatesh.pallipadi@intel.com
Impact: New mm functionality. Add pgprot_writecombine. pgprot_writecombine will be aliased to pgprot_noncached when not supported by the architecture.

2008-12-18x86: PAT: change pgprot_noncached to uc_minus instead of strong uc - v3venkatesh.pallipadi@intel.com
Impact: mm behavior change. Make pgprot_noncached uc_minus instead of strong UC. This will make pgprot_noncached to be in line with ioremap_nocache() and all the other APIs that map page uc_minus on uc request.

2008-12-18x86: PAT: implement track/untrack of pfnmap regions for x86 - v3venkatesh.pallipadi@intel.com
Impact: New mm functionality. Hookup remap_pfn_range and vm_insert_pfn and corresponding copy and free routines with reserve and free tracking. reserve and free here only takes care of non RAM region mapping. For RAM region, driver should use set_memory_[uc|wc|wb] to set the cache type and then setup the mapping for user pte. We can bypass below reserve/free in that case.

2008-12-18x86: PAT: add follow_pfnmp_pte routine to help tracking pfnmap pages - v3venkatesh.pallipadi@intel.com
Impact: New currently unused interface. Add a generic interface to follow pfn in a pfnmap vma range. This is used by one of the subsequent x86 PAT related patch to keep track of memory types for vma regions across vma copy and free.

2008-12-18x86: PAT: store vm_pgoff for all linear_over_vma_region mappings - v3venkatesh.pallipadi@intel.com
Impact: Code transformation, new functions added should have no effect. Drivers use mmap followed by pgprot_* and remap_pfn_range or vm_insert_pfn, in order to export reserved memory to userspace. Currently, such mappings are not tracked and hence not kept consistent with other mappings (/dev/mem, pci resource, ioremap) for the sme memory, that may exist in the system. The following patchset adds x86 PAT attribute tracking and untracking for pfnmap related APIs. First three patches in the patchset are changing the generic mm code to fit in this tracking. Last four patches are x86 specific to make things work with x86 PAT code. The patchset aso introduces pgprot_writecombine interface, which gives writecombine mapping when enabled, falling back to pgprot_noncached otherwise. This patch: While working on x86 PAT, we faced some hurdles with trackking remap_pfn_range() regions, as we do not have any information to say whether that PFNMAP mapping is linear for the entire vma range or it is smaller granularity regions within the vma. A simple solution to this is to use vm_pgoff as an indicator for linear mapping over the vma region. Currently, remap_pfn_range only sets vm_pgoff for COW mappings. Below patch changes the logic and sets the vm_pgoff irrespective of COW. This will still not be enough for the case where pfn is zero (vma region mapped to physical address zero). But, for all the other cases, we can look at pfnmap VMAs and say whether the mappng is for the entire vma region or not.

2008-12-17USB: skip Set-Interface(0) if already in altsetting 0Alan Stern
When a driver unbinds from an interface, usbcore always sends a Set-Interface request to reinstall altsetting 0.

To avoid such problems, this patch (as1180) arranges to send the Set-Interface request only when the interface is not already in altsetting 0.

2008-12-16mm: Don't touch uninitialized variable in do_pages_stat_array()KOSAKI Motohiro
Commit 80bba1290ab5122c60cdb73332b26d288dc8aedd removed one necessary variable initialization. As a result following warning happened: CC mm/migrate.o mm/migrate.c: In function 'sys_move_pages': mm/migrate.c:1001: warning: 'err' may be used uninitialized in this function More unfortunately, if find_vma() failed, kernel read uninitialized memory.

2008-12-16powerpc/cell/axon-msi: Fix MSI after kexecArnd Bergmann
Commit d015fe995 'powerpc/cell/axon-msi: Retry on missing interrupt' has turned a rare failure to kexec on QS22 into a reproducible error, which we have now analysed. The problem is that after a kexec, the MSIC hardware still points into the middle of the old ring buffer. We set up the ring buffer during reboot, but not the offset into it. On older kernels, this would cause a storm of thousands of spurious interrupts after a kexec, which would most of the time get dropped silently. With the new code, we time out on each interrupt, waiting for it to become valid. If more interrupts come in that we time out on, this goes on indefinitely, which eventually leads to a hard crash. The solution in this commit is to read the current offset from the MSIC when reinitializing it. This now works correctly, as expected.

2008-12-16powerpc: Fix bootmem reservation on uninitialized nodeDave Hansen
careful_allocation() was calling into the bootmem allocator for nodes which had not been fully initialized and caused a previous bug: http://patchwork.ozlabs.org/patch/10528/ So, I merged a few broken out loops in do_init_bootmem() to fix it. That changed the code ordering. I think this bug is triggered by having reserved areas for a node which are spanned by another node's contents. In the mark_reserved_regions_for_nid() code, we attempt to reserve the area for a node before we have allocated the NODE_DATA() for that nid. We do this since I reordered that loop. I suck. This is causing crashes at bootup on some systems, as reported by Jon Tollefson. This may only present on some systems that have 16GB pages reserved. But, it can probably happen on any system that is trying to reserve large swaths of memory that happen to span other nodes' contents. This commit ensures that we do not touch bootmem for any node which has not been initialized, and also removes a compile warning about an unused variable.

2008-12-16powerpc: Check for valid hugepage size in hugetlb_get_unmapped_areaBrian King
It looks like most of the hugetlb code is doing the correct thing if hugepages are not supported, but the mmap code is not. If we get into the mmap code when hugepages are not supported, such as in an LPAR which is running Active Memory Sharing, we can oops the kernel. This fixes the oops being seen in this path. oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=1024 NUMA pSeries Modules linked in: nfs(N) lockd(N) nfs_acl(N) sunrpc(N) ipv6(N) fuse(N) loop(N) dm_mod(N) sg(N) ibmveth(N) sd_mod(N) crc_t10dif(N) ibmvscsic(N) scsi_transport_srp(N) scsi_tgt(N) scsi_mod(N) Supported: No NIP: c000000000038d60 LR: c00000000003945c CTR: c0000000000393f0 REGS: c000000077e7b830 TRAP: 0300 Tainted: G (2.6.27.5-bz50170-2-ppc64) MSR: 8000000000009032 <EE,ME,IR,DR> CR: 44000448 XER: 20000001 DAR: c000002000af90a8, DSISR: 0000000040000000 TASK = c00000007c1b8600[4019] 'hugemmap01' THREAD: c000000077e78000 CPU: 6 GPR00: 0000001fffffffe0 c000000077e7bab0 c0000000009a4e78 0000000000000000 GPR04: 0000000000010000 0000000000000001 00000000ffffffff 0000000000000001 GPR08: 0000000000000000 c000000000af90c8 0000000000000001 0000000000000000 GPR12: 000000000000003f c000000000a73880 0000000000000000 0000000000000000 GPR16: 0000000000000000 0000000000000000 0000000000000000 0000000000010000 GPR20: 0000000000000000 0000000000000003 0000000000010000 0000000000000001 GPR24: 0000000000000003 0000000000000000 0000000000000001 ffffffffffffffb5 GPR28: c000000077ca2e80 0000000000000000 c00000000092af78 0000000000010000 NIP [c000000000038d60] .slice_get_unmapped_area+0x6c/0x4e0 LR [c00000000003945c] .hugetlb_get_unmapped_area+0x6c/0x80 Call Trace: [c000000077e7bbc0] [c00000000003945c] .hugetlb_get_unmapped_area+0x6c/0x80 [c000000077e7bc30] [c000000000107e30] .get_unmapped_area+0x64/0xd8 [c000000077e7bcb0] [c00000000010b140] .do_mmap_pgoff+0x140/0x420 [c000000077e7bd80] [c00000000000bf5c] .sys_mmap+0xc4/0x140 [c000000077e7be30] [c0000000000086b4] syscall_exit+0x0/0x40 Instruction dump: fac1ffb0 fae1ffb8 fb01ffc0 fb21ffc8 fb41ffd0 fb61ffd8 fb81ffe0 fbc1fff0 fbe1fff8 f821fef1 f8c10158 f8e10160 <7d49002e> f9010168 e92d01b0 eb4902b0 Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
