This is because nilfs_last_byte(), which is called by nilfs_find_entry() and others to calculate the number of valid bytes of directory data in a page from i_size and the page index, loses the upper 32 bits of the 64-bit size information due to an inappropriate type of local variable to which the i_size value is assigned. This caused a large byte offset value due to underflow in the end address calculation in the calling nilfs_find_entry(), resulting in memory access that exceeds the folio/page size. Fix this issue by changing the type of the local variable causing the bit loss from "unsigned int" to "u64". The return value of nilfs_last_byte() is also of type "unsigned int", but it is truncated so as not to exceed PAGE_SIZE and no bit loss occurs, so no change is required.

That's not the case, as I discovered when I ran on a new configuration on my test machine. Fix this by skipping NULL pages in unpin_user_pages(), just like unpin_folios() already does.

[PATCH v2] of: property: fw_devlink: Do not use interrupt-parent directly

by Samuel Holland

commit 7f00be96f125 ("of: property: Add device link support for interrupt-parent, dmas and -gpio(s)") started adding device links for the interrupt-parent property. commit 4104ca776ba3 ("of: property: Add fw_devlink support for interrupts") and commit f265f06af194 ("of: property: Fix fw_devlink handling of interrupts/interrupts-extended") later added full support for parsing the interrupts and interrupts-extended properties, which includes looking up the node of the parent domain. This made the handler for the interrupt-parent property redundant. In fact, creating device links based solely on interrupt-parent is problematic, because it can create spurious cycles. A node may have this property without itself being an interrupt controller or consumer. For example, this property is often present in the root node or a /soc bus node to set the default interrupt parent for child nodes. However, it is incorrect for the bus to depend on the interrupt controller, as some of the bus's children may not be interrupt consumers at all or may have a different interrupt parent. Resolving these spurious dependency cycles can cause an incorrect probe order for interrupt controller drivers. This was observed on a RISC-V system with both an APLIC and IMSIC under /soc, where interrupt-parent in /soc points to the APLIC, and the APLIC msi-parent points to the IMSIC. fw_devlink found three dependency cycles and attempted to probe the APLIC before the IMSIC. After applying this patch, there were no dependency cycles and the probe order was correct.
