If more than 1024 event channels are bound to a evtchn device then it possible (even with well behaved applications) for the ring to overflow and events to be lost (reported as an -EFBIG error). Dynamically increase the size of the ring so there is always enough space for all bound events. Well behaved applicables that only unmask events after draining them from the ring can thus no longer lose events. However, an application could unmask an event before draining it, allowing multiple entries per port to accumulate in the ring, and a overflow could still occur. So the overflow detection and reporting is retained. The ring size is initially only 64 entries so the common use case of an application only binding a few events will use less memory than before. The ring size may grow to 512 KiB (enough for all 2^17 possible channels). This order 7 kmalloc() may fail due to memory fragmentation, so we fall back to trying vmalloc(). Signed-off-by:

Even though initcall return values are typically ignored, the prototype is to return 0 on success or a negative errno value on error. So fix the arm_enable_runtime_services() implementation to return 0 on conditions that are not in fact errors, and return a meaningful error code otherwise. Signed-off-by:

Add NULL return value checks to two invocations of early_memremap() in the UEFI init code. For the UEFI configuration tables, we just warn since we have a better chance of being able to report the issue in a way that can actually be noticed by a human operator if we don't abort right away. For the UEFI memory map, however, all we can do is panic() since we cannot proceed without a description of memory. Signed-off-by:

After commit 8c058b0b ("x86/irq: Probe for PIC presence before allocating descs for legacy IRQs") early_irq_init() will no longer preallocate descriptors for legacy interrupts if PIC does not exist, which is the case for Xen PV guests. Therefore we may need to allocate those descriptors ourselves. Signed-off-by:

Doing so will cause the grant to be unmapped and then, during fault handling, the fault to be mistakenly treated as NUMA hint fault. In addition, even if those maps could partcipate in NUMA balancing, it wouldn't provide any benefit since we are unable to determine physical page's node (even if/when VNUMA is implemented). Marking grant maps' VMAs as VM_IO will exclude them from being part of NUMA balancing. Signed-off-by:

This reverts commit 348a65cd. Incorrect page table manipulation that does not respect the ARM ARM recommended break-before-make sequence may lead to TLB conflicts. The contiguous PTE patch makes the system even more susceptible to such errors by changing the mapping from a single page to a contiguous range of pages. An additional TLB invalidation would reduce the risk window, however, the correct fix is to switch to a temporary swapper_pg_dir. Once the correct workaround is done, the reverted commit will be re-applied. Signed-off-by:

Under some unusual context-switching patterns, it is possible to end up with multiple threads from the same mm running concurrently with different ASIDs: 1. CPU x schedules task t with mm p containing ASID a and generation g This task doesn't block and the CPU doesn't context switch. So: * per_cpu(active_asid, x) = {g,a} * p->context.id = {g,a} 2. Some other CPU generates an ASID rollover. The global generation is now (g + 1). CPU x is still running t, with no context switch and so per_cpu(reserved_asid, x) = {g,a} 3. CPU y schedules task t', which shares mm p with t. The generation mismatches, so we take the slowpath and hit the reserved ASID from CPU x. p is then updated so that p->context.id = {g + 1,a} 4. CPU y schedules some other task u, which has an mm != p. 5. Some other CPU generates *another* CPU rollover. The global generation is now (g + 2). CPU x is still running t, with no context switch and so per_cpu(reserved_asid, x) = {g,a}. 6. CPU y once again schedules task t', but now *fails* to hit the reserved ASID from CPU x because of the generation mismatch. This results in a new ASID being allocated, despite the fact that t is still running on CPU x with the same mm. Consequently, TLBIs (e.g. as a result of CoW) will not be synchronised between the two threads. This patch fixes the problem by updating all of the matching reserved ASIDs when we hit on the slowpath (i.e. in step 3 above). This keeps the reserved ASIDs in-sync with the mm and avoids the problem. Reported-by:

If hardware-driven P-state selection (HWP) is enabled, the "performance" mode of intel_pstate should only allow the processor to use the highest-performance P-state available. That is not the case currently, so make it actually happen. Acked-by:

pnfs_layout_process will check the returned layout stateid against what the kernel has in-core. If it turns out that the stateid we received is older, then we should resend the LAYOUTGET instead of falling back to MDS I/O. Signed-off-by:

If we pass in an empty nfs_fattr struct to nfs_update_inode, it will (correctly) not update any of the attributes, but it then clears the NFS_INO_INVALID_ATTR flag, which indicates that the attributes are up to date. Don't clear the flag if the fattr struct has no valid attrs to apply. Reviewed-by:

If we get no post-op attributes back from a SETATTR operation, then no attributes will of course be updated during the call to nfs_update_inode. We know however that the attributes are invalid at that point, since we just changed some of them. At the very least, the ctime will be bogus. If we get no post-op attributes back on the call, mark the attrcache invalid to reflect that fact. Reviewed-by:

Commit b3a72384 ("ARM/PCI: Replace pci_sys_data->align_resource with global function pointer") introduced an ARM-specific align_resource() function pointer. This is not portable to other arches and doesn't work for platforms with two different PCIe host bridge controllers. Move the function pointer to the pci_host_bridge structure so each host bridge driver can specify its own align_resource() function. Signed-off-by:
