[PATCH v2 1/1] riscv: alloc space exhausted

[PATCH v2 1/1] riscv: alloc space exhausted

[Heinrich Schuchardt]

When trying to run qemu-riscv64_smode_defconfig with 32 harts booting
fails. The debug UART shows a message

    alloc space exhausted

32 is the current maximum number of harts for machine virt in QEMU 7.0.

Raise the default for SYS_MALLOC_F_LEN to 16 KiB.

Move the setting to /Kconfig where we define SYS_MALLOC_F_LEN for
other architectures too.
