Linux kernel 6.1.21 compilation fails on raspberry pi aarch64 with gcc-13
How it fails:

erg_samowzbudnik,

You don't get a bzImage file as arm64 cannot boot a compressed kernel unless the boot loader does the decompression.

I can confirm the
Code:
make[2]: *** [scripts/gcc-plugins/Makefile:54: scripts/gcc-plugins/stackleak_plugin.so] Error 1
make[1]: *** [scripts/Makefile.build:500: scripts/gcc-plugins] Error 2
with gcc-13

I disabled the GCC Plugins option in
Code:
make menuconfig


I got
Code:
 $ uname -a
Linux Pi_Router SSD 6.1.42-v8+ #2 SMP Mon Jul 31 22:07:56 BST 2023 aarch64 GNU/Linux
from the 6.1.y branch in git yesterday.

Moved from Kernel & Hardware to Gentoo on ARM as its arm64

Great, thank you. Removed gcc-plugins and kernel builds.

Still does not boot, looks like there's confusion regarding mmc modules - never got hit by it and so didn't know there's quite a few:
CONFIG_MMC_BCM2835
CONFIG_MMC_BCM2835_MMC
CONFIG_MMC_BCM2835_DMA
CONFIG_MMC_BCM2835_SDHOST

I'll employ trial and error approach as I didn't find authoritative looking solution.
