Add a test module to verify memory alignment guarantees for Rust kernel allocators. The tests cover `Kmalloc`, `Vmalloc` and `KVmalloc` allocators with both standard and large page-aligned allocations. Key features of the tests: 1. Creates alignment-constrained types: - 128-byte aligned `Blob` - 8192-byte (4-page) aligned `LargeAlignBlob` 2. Validates allocators using `TestAlign` helper which: - Checks address alignment masks - Supports uninitialized allocations 3. Tests all three allocators with both alignment requirements: - Kmalloc with 128B and 8192B - Vmalloc with 128B and 8192B - KVmalloc with 128B and 8192B Link: https://lkml.kernel.org/r/d2e3d6454c1435713be0fe3c0dc444d2c60bba51.1753929369.git.zhuhui@kylinos.cn Co-developed-by: Geliang Tang <[email protected]> Signed-off-by: Geliang Tang <[email protected]> Signed-off-by: Hui Zhu <[email protected]> Reviewed-by: Kunwu Chan <[email protected]> Acked-by: Danilo Krummrich <[email protected]> Cc: Alex Gaynor <[email protected]> Cc: Alice Ryhl <[email protected]> Cc: Andreas Hindborg <[email protected]> Cc: Björn Roy Baron <[email protected]> Cc: Boqun Feng <[email protected]> Cc: Gary Guo <[email protected]> Cc: Liam Howlett <[email protected]> Cc: Lorenzo Stoakes <[email protected]> Cc: Miguel Ojeda <[email protected]> Cc: Trevor Gross <[email protected]> Cc: "Uladzislau Rezki (Sony)" <[email protected]> Cc: Vlastimil Babka <[email protected]> Signed-off-by: Andrew Morton <[email protected]>
