The virtgpu driver prints the last_seq variable using the %ld or %lu format string, which does not work correctly on all architectures and causes this compiler warning on ARM: drivers/gpu/drm/virtio/virtgpu_fence.c: In function 'virtio_timeline_value_str': drivers/gpu/drm/virtio/virtgpu_fence.c:64:22: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'long long int' [-Wformat=] snprintf(str, size, "%lu", atomic64_read(&fence->drv->last_seq)); ^ drivers/gpu/drm/virtio/virtgpu_debugfs.c: In function 'virtio_gpu_debugfs_irq_info': drivers/gpu/drm/virtio/virtgpu_debugfs.c:37:16: warning: format '%ld' expects argument of type 'long int', but argument 3 has type 'long long int' [-Wformat=] seq_printf(m, "fence %ld %lld\n", ^ In order to avoid the warnings, this changes the format strings to %llu and adds a cast to u64, which makes it work the same way everywhere.

Unlike shash algorithms, ahash drivers must implement export and import as their descriptors may contain hardware state and cannot be exported as is. Unfortunately some ahash drivers did not provide them and end up causing crashes with algif_hash.

Now that the NFS server advertises a maximum payload size of 1MB for RPC/RDMA again, it crashes in svc_process_common() when NFS client sends a 1MB NFS WRITE on an NFS/RDMA mount. The server has set up a 259 element array of struct page pointers in rq_pages[] for each incoming request. The last element of the array is NULL. When an incoming request has been completely received, rdma_read_complete() attempts to set the starting page of the incoming page vector: rqstp->rq_arg.pages = &rqstp->rq_pages[head->hdr_count]; and the page to use for the reply: rqstp->rq_respages = &rqstp->rq_arg.pages[page_no]; But the value of page_no has already accounted for head->hdr_count. Thus rq_respages now points past the end of the incoming pages. For NFS WRITE operations smaller than the maximum, this is harmless. But when the NFS WRITE operation is as large as the server's max payload size, rq_respages now points at the last entry in rq_pages, which is NULL. Fixes: cc9a903d ('svcrdma: Change maximum server payload . . .') BugLink: https://bugzilla.linux-nfs.org/show_bug.cgi?id=270 Signed-off-by:

Currently OF bios load fails for a few reasons: - checksum failure - bios size too small - no PCIR header - bios length not a multiple of 4 In this change, we resolve all of the above by ignoring any checksum failures (since OF VBIOS tends not to have a checksum), and faking the PCIR data when loading from OF.

We need to do this in order to prevent accesses to the device while it's powered down. Userspace may have an mmap of the fb, and there's no good way (that I know of) to prevent it from touching the device otherwise. This fixes some nasty races between runpm and plymouth on some systems, which result in the GPU getting very upset and hanging the boot. Signed-off-by:

SiS 761 chipset does not support AGP cards but has AGP capability (for the onboard video). At least PC Chips A31G board using this chipset has an AGP-like AGPro slot that's wired to the PCI bus. Enabling AGP will fail (GPU lockup and software fbcon, X11 hangs). Add support for matching just the host bridge in nvkm_device_agp_quirks and add entry for SiS 761 with mode 0 (AGP disabled).

We used to treat d_is_negative() after lookup_fast() as "fall with ENOENT". That was wrong - checking ->d_flags outside of ->d_seq protection is unreliable and failing with hard error on what should've fallen back to non-RCU pathname resolution is a bug. Unfortunately, we'd pulled the test too far up and ran afoul of another kind of staleness. The dentry might have been absolutely stable from the RCU point of view (and we might be on UP, etc), but stale from the remote fs point of view. If ->d_revalidate() returns "it's actually stale", dentry gets thrown away and the original code wouldn't even have looked at its ->d_flags. What we need is to check ->d_flags where 766c4cbf does (prior to ->d_seq validation) but only use the result in cases where we do not discard this dentry outright" Reported-by:
