[PATCH] atomic: Specify natural alignment for atomic_t

by Finn Thain

Some recent commits incorrectly assumed the natural alignment of locks. That assumption fails on Linux/m68k (and, interestingly, would have failed on Linux/cris also). This leads to spurious warnings from the hang check code. Fix this bug by adding the necessary 'aligned' attribute.

The print format to print the dynamic string changed from "%*s" to "%s" because another location (__set_synth_event_print_fmt()) exported this to user space, and user space did not need that.

In particular, before commit 9cb28da54643 ("mm/gup: handle hugetlb in the generic follow_page_mask code"), GUP(FOLL_SPLIT_PMD) would just have returned a page. In particular, hugetlb folios that are not PMD-sized would never have been prone to FOLL_SPLIT_PMD. hugetlb folios can be anonymous, and page_make_device_exclusive_one() is not really prepared for handling them at all.

[PATCH v2] ARM: dts: socfpga: sodia: Fix mdio bus probe and PHY address

by Nobuhiro Iwamatsu

On SoCFPGA/Sodia board, mdio bus cannot be probed, so the PHY cannot be found and the network device does not work. ``` stmmaceth ff702000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) ``` To probe the mdio bus, add "snps,dwmac-mdio" as compatible string of the mdio bus. Also the PHY address connected to this board is 4. Therefore, change to 4.

The legacy users of exportfs_encode_fh(), namely, nfsd and name_to_handle_at(2) syscall are ready to cope with the possibility of failure to encode a file handle. There are a few other users of exportfs_encode_{fh,fid}() that currently have a WARN_ON() assertion when ->encode_fh() fails. Relax those assertions because they are wrong. The second linked bug report states commit 16aac5ad1fa9 ("ovl: support encoding non-decodable file handles") in v6.6 as the regressing commit, but this is not accurate. The aforementioned commit only increases the chances of the assertion and allows triggering the assertion with the reproducer using overlayfs, inotify and drop_caches. Triggering this assertion was always possible with other filesystems and other reasons of ->encode_fh() failures and more particularly, it was also possible with the exact same reproducer using overlayfs that is mounted with options index=on,nfs_export=on also on kernels < v6.6. Therefore, I am not listing the aforementioned commit as a Fixes commit. Backport hint: this patch will have a trivial conflict applying to v6.6.y, and other trivial conflicts applying to stable kernels < v6.6.
