[PATCH V5 0/3] Rust support for powerpc

From: Mukesh Kumar Chaurasiya (IBM) <hidden>
Date: 2026-02-10 07:30:15
Also in: linux-doc, lkml, rust-for-linux

Enable experimental rust support for ppc64le and ppc32be. The patch for
ppc32 has been provided by Link Mauve[1] and ppc64le support[2] has been 
merged over it. ppc32 needs some toolchain fixes mentioned in the patch 
`rust: Add PowerPC support` and the discussion for that is done here[1]. 

This has been tested on powernv9 hardware and power10 pseries qemu. I
I request Link to test the ppc32 part as i don't have a hardware to test
it out.
