** Description changed:
[ Impact ]
Due to infrastructural issues, the validation build for LP#2164666 only built
tools
on each architecture, not the whole kernel. As a result, a few build failures
have snuck
into the tree which need to be resolved. A list of the broken commits is
presented below:
- * d14116da71c9 ("accel/amdxdna: Create shared functions for AIE2 and AIE4")
- * f7688a6921ed ("bpf: Take mmap_lock in zap_pages()")
+ * d14116da71c9 ("accel/amdxdna: Create shared functions for AIE2 and AIE4")
+ * f7688a6921ed ("bpf: Take mmap_lock in zap_pages()")
[ Fix ]
Resolute: Backporting and creation of the following fixes:
- * ece3e8980907 (Move to aie2_free_msg_buffer() function from the previous
macro to apply a missing hunk)
- * SAUCE PATCH (Add missing NULL argument to the zap_page_range_single()
function)
+ * ece3e8980907 (Move to aie2_free_msg_buffer() function from the previous
macro to apply a missing hunk)
+ * SAUCE PATCH (Add missing NULL argument to the zap_page_range_single()
function)
+
+ Given that the first commit above also introduces bugs into the kernel, both
+ of the following commits are also picked.
+
+ 140cfee588af ("accel/amdxdna: Return ERR_PTR on dma_alloc_noncoherent
failure")
+ 432fafdc9a31 ("accel/amdxdna: Fix memory leak in amdxdna_iommu_alloc()")
[ Testing ]
- Successful local build on an arm64 machine as well as validation on
- cloud builders for all other supported ARCHs.
+ Successful local builds on my amd64 and arm64 machines as well as
+ validation on cloud builders.
[ What could go wrong ]
Given that the previous state of the tree was failure to build, things do not
get much worse. Nonetheless,
- The patches applied attempt to keep the tree as close to upstream as possible
while correcting the stable update.
- The only subsystems affected are:
+ The patches are changed only as subtly as neccessary to correct the stable
update. The subsystems affected are as follows:
- * accel/amdxdna
- * bpf
+ * accel/amdxdna
+ * bpf
