2013-10-10Btrfs: fix oops caused by the space balance and dead rootsMiao Xie
When doing space balance and subvolume destroy at the same time, we met the following oops: kernel BUG at fs/btrfs/relocation.c:2247!

It was not right here, because though the root was dead(refs == 0), but the space it held still need be relocated, or we could not remove the block group. So in this case, we should return the root no matter it is dead or not.

2013-10-10Btrfs: insert orphan roots into fs radix treeMiao Xie
Now we don't drop all the deleted snapshots/subvolumes before the space balance. It means we have to relocate the space which is held by the dead snapshots/subvolumes. So we must into them into fs radix tree, or we would forget to commit the change of them when doing transaction commit, and it would corrupt the metadata.

2013-10-10Btrfs: limit delalloc pages outside of find_delalloc_rangeJosef Bacik
Liu fixed part of this problem and unfortunately I steered him in slightly the wrong direction and so didn't completely fix the problem. The problem is we limit the size of the delalloc range we are looking for to max bytes and then we try to lock that range. If we fail to lock the pages in that range we will shrink the max bytes to a single page and re loop. However if our first page is inside of the delalloc range then we will end up limiting the end of the range to a period before our first page. This is illustrated below [0 -------- delalloc range --------- 256mb] [page] So find_delalloc_range will return with delalloc_start as 0 and end as 128mb, and then we will notice that delalloc_start < *start and adjust it up, but not adjust delalloc_end up, so things go sideways. To fix this we need to not limit the max bytes in find_delalloc_range, but in find_lock_delalloc_range and that way we don't end up with this confusion.

2013-10-10Btrfs: use right root when checking for hash collisionJosef Bacik
btrfs_rename was using the root of the old dir instead of the root of the new dir when checking for a hash collision, so if you tried to move a file into a subvol it would freak out because it would see the file you are trying to move in its current root. This fixes the bug where this would fail btrfs subvol create test1 btrfs subvol create test2 mv test1 test2.

2013-10-10kvm: ppc: booke: check range page invalidation progress on page setupBharat Bhushan
When the MM code is invalidating a range of pages, it calls the KVM kvm_mmu_notifier_invalidate_range_start() notifier function, which calls kvm_unmap_hva_range(), which arranges to flush all the TLBs for guest pages. However, the Linux PTEs for the range being flushed are still valid at that point. We are not supposed to establish any new references to pages in the range until the ...range_end() notifier gets called. The PPC-specific KVM code doesn't get any explicit notification of that; instead, we are supposed to use mmu_notifier_retry() to test whether we are or have been inside a range flush notifier pair while we have been referencing a page. This patch calls the mmu_notifier_retry() while mapping the guest page to ensure we are not referencing a page when in range invalidation. This call is inside a region locked with kvm->mmu_lock, which is the same lock that is called by the KVM MMU notifier functions, thus ensuring that no new notification can proceed while we are in the locked region.

2013-10-10KVM: nVMX: fix shadow on EPTGleb Natapov
72f857950f6f19 broke shadow on EPT. This patch reverts it and fixes PAE on nEPT (which reverted commit fixed) in other way. Shadow on EPT is now broken because while L1 builds shadow page table for L2 (which is PAE while L2 is in real mode) it never loads L2's GUEST_PDPTR[0-3]. They do not need to be loaded because without nested virtualization HW does this during guest entry if EPT is disabled, but in our case L0 emulates L2's vmentry while EPT is enables, so we cannot rely on vmcs12->guest_pdptr[0-3] to contain up-to-date values and need to re-read PDPTEs from L2 memory. This is what kvm_set_cr3() is doing, but by clearing cache bits during L2 vmentry we drop values that kvm_set_cr3() read from memory. So why the same code does not work for PAE on nEPT? kvm_set_cr3() reads pdptes into vcpu->arch.walk_mmu->pdptrs[]. walk_mmu points to vcpu->arch.nested_mmu while nested guest is running, but ept_load_pdptrs() uses vcpu->arch.mmu which contain incorrect values. Fix that by using walk_mmu in ept_(load|save)_pdptrs.

2013-10-09hwmon: (applesmc) Always read until end of dataHenrik Rydberg
The crash reported and investigated in commit 5f4513 turned out to be caused by a change to the read interface on newer (2012) SMCs. Tests by Chris show that simply reading the data valid line is enough for the problem to go away. Additional tests show that the newer SMCs no longer wait for the number of requested bytes, but start sending data right away. Apparently the number of bytes to read is no longer specified as before, but instead found out by reading until end of data. Failure to read until end of data confuses the state machine, which eventually causes the crash. As a remedy, assuming bit0 is the read valid line, make sure there is nothing more to read before leaving the read function. Tested to resolve the original problem, and runtested on MBA3,1, MBP4,1, MBP8,2, MBP10,1, MBP10,2. The patch seems to have no effect on machines before 2012.
