This reverts commit 59287c09. Hugh Dickins reports that it causes random failures on x86 with SuSE 10.2, and points out "Isn't that randomization, anywhere from 0x10000 to ELF_ET_DYN_BASE, sure to place the ET_DYN from time to time just where the comment says it's trying to avoid? I assume that somehow results in the error reported." (where the comment in question is the existing comment in the source code about mmap/brk clashes). Suggested-by:

On ia64, the various functions that make up cn_proc.c cause kernel unaligned access errors. If you are using these, for example, to get notification about all tasks forking and exiting, you get multiple unaligned access errors per process. Use put_unaligned() in the appropriate palces to fix this. Signed-off-by:

At the end of shrink_all_memory() we forget to recalculate lru_pages: it can be zero. Fix that up, and add a helper function for this operation too. Also, recalculate lru_pages each time around the inner loop to get the balancing correct. Cc: "Rafael J. Wysocki" <rjw@sisk.pl> Cc: Pavel Machek <pavel@ucw.cz> Signed-off-by:

Looks like this is the problem, which point Al Viro some time ago: ufs's get_block callback allocates 16k of disk at a time, and links that entire 16k into the file's metadata. But because get_block is called for only a single buffer_head (a 2k buffer_head in this case?) we are only able to tell the VFS that this 2k is buffer_new(). So when ufs_getfrag_block() is later called to map some more data in the file, and when that data resides within the remaining 14k of this fragment, ufs_getfrag_block() will incorrectly return a !buffer_new() buffer_head. I don't see _right_ way to do nullification of whole block, if use inode page cache, some pages may be outside of inode limits (inode size), and will be lost; if use blockdev page cache it is possible to zero real data, if later inode page cache will be used. The simpliest way, as can I see usage of block device page cache, but not only mark dirty, but also sync it during "nullification". I use my simple tests collection, which I used for check that create,open,write,read,close works on ufs, and I see that this patch makes ufs code 18% slower then before. Signed-off-by:

These days, if you swapoff when there isn't enough memory, OOM killer gives "BUG: scheduling while atomic" and the machine hangs: badness() needs to do its PF_SWAPOFF return after the task_unlock (tasklist_lock is also held here, so p isn't going to be freed: PF_SWAPOFF might get turned off at any moment, but that doesn't really matter).

Both process_zones() and drain_node_pages() check for populated zones before touching pagesets. However, __drain_pages does not do so, This may result in a NULL pointer dereference for pagesets in unpopulated zones if a NUMA setup is combined with cpu hotplug. Initially the unpopulated zone has the pcp pointers pointing to the boot pagesets. Since the zone is not populated the boot pageset pointers will not be changed during page allocator and slab bootstrap. If a cpu is later brought down (first call to __drain_pages()) then the pcp pointers for cpus in unpopulated zones are set to NULL since __drain_pages does not first check for an unpopulated zone. If the cpu is then brought up again then we call process_zones() which will ignore the unpopulated zone. So the pageset pointers will still be NULL. If the cpu is then again brought down then __drain_pages will attempt to drain pages by following the NULL pageset pointer for unpopulated zones. Signed-off-by:

The HPT37x driver very carefully handles DMA completions and the needed fixups are done on pci registers 0x50 and 0x52. This is unfortunate because the actual registers are 0x50 and 0x54. Fixing this offset cures the second channel problems reported. Secondly there are some problems with the HPT370 and certain ATA drives. The filter code however only filters ATAPI devices due to a reversed type check. Signed-off-by:

If we emulate a write, we fail to set the dirty bit on the guest pte, leading the guest to believe the page is clean, and thus lose data. Bad. Fix by setting the guest pte dirty bit under such conditions. Signed-off-by:

Avi Kivity authored
If we reduce permissions on a pte, we must flush the cached copy of the pte from the guest's tlb. This is implemented at the moment by flushing the entire guest tlb, and can be improved by flushing just the relevant virtual address, if it is known. Signed-off-by:

The mmu sometimes needs memory for reverse mapping and parent pte chains. however, we can't allocate from within the mmu because of the atomic context. So, move the allocations to a central place that can be executed before the main mmu machinery, where we can bail out on failure before any damage is done. (error handling is deffered for now, but the basic structure is there) Signed-off-by:

Because mmu pages have attached rmap and parent pte chain structures, we need to zap them before freeing so the attached structures are freed. Signed-off-by:

cmpxchg8b uses edx:eax as the compare operand, not edi:eax. cmpxchg8b is used by 32-bit pae guests to set page table entries atomically, and this is emulated touching shadowed guest page tables. Also, implement it for 32-bit hosts. Signed-off-by:

Avi Kivity authored
In fork() (or when we protect a page that is no longer a page table), we can experience floods of writes to a page, which have to be emulated. This is expensive. So, if we detect such a flood, zap the page so subsequent writes can proceed natively. Signed-off-by:
