[PATCH 0/3] Fix alignment issue and prepare for rust 1.71

Hi Miguel,

I end up with this series:

(background: https://lore.kernel.org/rust-for-linux/CANiq72=pb18B6NOcXF03d0ctOP8kv2dqnUeNyEuSvuDb=vs-0g@xxxxxxxxxxxxxx/)

Patch #1: introduces the core helper function that help calculate the
correct size for krealloc(), and also use the helper function to fix
`__rust_*` ones, this should be backported to stable kernels hence the
Cc.

Patch #2: use the helper function in KernelAllocator

Patch #3: Bjorn's patch with correct use of the helper function.

I have to add a few more SAFETY comments in these `__rust_*` functions,
which may cause conflict with your 1.71 series.

Since all previous patches get refactored a bit, I dropped all the
Reviewed-bys, appreciate anyone to take a look, thanks!

Regards,
Boqun
