Geoffrey Le Gourriérec	742f37de8d	configs/qemu_*: bump kernel version to 5.10.7 ... 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.

Romain Naour	5259a39c7a	configs/qemu_mips64r6: fix Linux kernel build with gcc 10.x ... From [1] "GCC 10 (PR 91233) won't silently allow registers that are not architecturally available to be present in the clobber list anymore, resulting in build failure for mips*r6 targets in form of: ... .../sysdep.h:146:2: error: the register ‘lo’ cannot be clobbered in ‘asm’ for the current target 146 | __asm__ volatile ( \ | ^~~~~~~ This is because base R6 ISA doesn't define hi and lo registers w/o DSP extension. This patch provides the alternative clobber list for r6 targets that won't include those registers." Since kernel 5.4 and mips support for generic vDSO [2], the kernel fails to build for mips r6 cpus with gcc 10 for the same reason as glibc.
