	Update our vendored copy of `zerocopy` (and `zerocopy-derive`) to v0.8.54. It is a very small delta from v0.8.52, and most importantly it resolves the unexpected lack of inlining [1] which triggered a modpost error under `CONFIG_CC_OPTIMIZE_FOR_SIZE=y` reported by Alexandre using Gary's suggestion [2]: ERROR: modpost: "_RNvMNtCs5wX7wwEUCR9_8zerocopy6layoutNtB2_8SizeInfo24try_to_nonzero_elem_size" [drivers/gpu/nova-core.ko] undefined! ERROR: modpost: "_RNvNtCs5wX7wwEUCR9_8zerocopy4util18padding_needed_for" [drivers/gpu/nova-core.ko] undefined! It also resolves `most_traits` being unexpectedly documented [3] that I reported and adds a missing SPDX license identifier [4] that I requested to match the kernel version.

2026-07-11	rust: zerocopy: update to v0.8.52	Miguel Ojeda
	Update our vendored copy of `zerocopy` (and `zerocopy-derive`) to v0.8.52. Most SPDX identifiers have been added upstream at our request [1] (without parentheses -- supporting them is an issue on the kernel side, but it does already reduce our differences). The CSS one for `rustdoc` was added too [2], but will be picked up in a later version. For `zerocopy`, enable `--cfg no_fp_fmt_parse`, which was added at our request to avoid our local workaround [3]. This means one less difference, thus indicate so in our `README.md`. For `zerocopy-derive`, enable `--cfg zerocopy_unstable_linux`. This allows us to use `#[derive(zerocopy_derive::most_traits)]`, a new feature upstream added for us [4]. We noticed a minor doc render bug [5], which will be fixed for a future version too.

2026-06-09	rust: zerocopy-derive: add `README.md`	Miguel Ojeda
	Originally, when the Rust upstream `alloc` standard library crate was vendored in commit 057b8d257107 ("rust: adapt `alloc` crate to the kernel"), a `README.md` file was added to explain the provenance and licensing of the source files. Thus do the same for the `zerocopy-derive` crate.
