Linus Torvalds f4e0ff7e45 Rust changes for v6.18
Toolchain and infrastructure:
 
  - Derive 'Zeroable' for all structs and unions generated by 'bindgen'
    where possible and corresponding cleanups. To do so, add the
    'pin-init' crate as a dependency to 'bindings' and 'uapi'.
 
    It also includes its first use in the 'cpufreq' module, with more to
    come in the next cycle.
 
  - Add warning to the 'rustdoc' target to detect broken 'srctree/' links
    and fix existing cases.
 
  - Remove support for unused (since v6.16) host '#[test]'s, simplifying
    the 'rusttest' target. Tests should generally run within KUnit.
 
 'kernel' crate:
 
  - Add 'ptr' module with a new 'Alignment' type, which is always a power
    of two and is used to validate that a given value is a valid
    alignment and to perform masking and alignment operations:
 
        // Checked at build time.
        assert_eq!(Alignment:🆕:<16>().as_usize(), 16);
 
        // Checked at runtime.
        assert_eq!(Alignment::new_checked(15), None);
 
        assert_eq!(Alignment::of::<u8>().log2(), 0);
 
        assert_eq!(0x25u8.align_down(Alignment:🆕:<0x10>()), 0x20);
        assert_eq!(0x5u8.align_up(Alignment:🆕:<0x10>()), Some(0x10));
        assert_eq!(u8::MAX.align_up(Alignment:🆕:<0x10>()), None);
 
    It also includes its first use in Nova.
 
  - Add 'core::mem::{align,size}_of{,_val}' to the prelude, matching
    Rust 1.80.0.
 
  - Keep going with the steps on our migration to the standard library
    'core::ffi::CStr' type (use 'kernel::{fmt, prelude::fmt!}' and use
    upstream method names).
 
  - 'error' module: improve 'Error::from_errno' and 'to_result'
    documentation, including examples/tests.
 
  - 'sync' module: extend 'aref' submodule documentation now that it
    exists, and more updates to complete the ongoing move of 'ARef' and
    'AlwaysRefCounted' to 'sync::aref'.
 
  - 'list' module: add an example/test for 'ListLinksSelfPtr' usage.
 
  - 'alloc' module:
 
    - Implement 'Box::pin_slice()', which constructs a pinned slice of
      elements.
 
    - Provide information about the minimum alignment guarantees of
      'Kmalloc', 'Vmalloc' and 'KVmalloc'.
 
    - Take minimum alignment guarantees of allocators for
      'ForeignOwnable' into account.
 
    - Remove the 'allocator_test' (including 'Cmalloc').
 
    - Add doctest for 'Vec::as_slice()'.
 
    - Constify various methods.
 
  - 'time' module:
 
    - Add methods on 'HrTimer' that can only be called with exclusive
      access to an unarmed timer, or from timer callback context.
 
    - Add arithmetic operations to 'Instant' and 'Delta'.
 
    - Add a few convenience and access methods to 'HrTimer' and
      'Instant'.
 
 'macros' crate:
 
  - Reduce collections in 'quote!' macro.
 
 And a few other cleanups and improvements.
