Bump most QEMU defconfigs (every one that was previously on 5.4.y)
to latest longterm kernel 5.10.7.
Please note the following exceptions/modifications:
- board/qemu/qemu_s390x_defconfig: ignored (already up to date)
- board/qemu/sh4*-r2d:
- Remove the remaining kernel patch [1] provided by Alan Modra
fixing rodata alignment, carried here by Romain Naour [2] to
fix an issue preventing kernel from booting with binutils 2.23.
Patch is present in upstream Linux now.
- Fix compile-time error regarding 64-bit time data structures
from kernel headers when building with uclibc. Previous fix [3]
existed upstream; but see details below.
- board/qemu/ppc-mpc8544ds: Updated kernel patch
- board/qemu/arm-versatile: Updated kernel patch
- board/qemu/mips*r6*: Updated kernel patch
Tested on all configs/qemu* configurations. [4]

Subject: [PATCH] powerpc: Fix -mcpu= options for SPE-only compiler
|
|
|
|
GCC for Debian's "powerpcspe" architecture only supports 32-bit
|
|
SPE targets, and using -mcpu=powerpc or -mcpu=powerpc64 is a fatal
|
|
error.
|
|
|
|
* Change the test for a biarch compiler to pass both the -m32 and -m64
|
|
options, so that it doesn't catch 32-bit-only compilers
|
|
* Add an ifdef CONFIG_PPC64 around the 64-bit CPU option definitions
