[RFC PATCH linux dev-5.4 3/4] ARM: configs: aspeed-g5: Enable kprobes

[Andrew Jeffery]

Enable kprobes to improve the debugging experience on the AST2500 and
later.

Setting CONFIG_KPROBES=y results in the following change in kernel size:

Before:
         $ size vmlinux
            text    data     bss     dec     hex filename
         8240349 2388862  172304 10801515         a4d16b vmlinux
         $ stat --printf '%s\n' *.zImage
         3458368

After:
         $ size vmlinux
            text    data     bss     dec     hex filename
         8279214 2399530  176912 10855656         a5a4e8 vmlinux
         $ stat --printf '%s\n' *.zImage
         3471880

This gives a 54,141 byte increase to vmlinux and a 13,512 byte increase
to the size of the compressed kernel image. In the most constrained BMC
flash layout (arch/arm/boot/dts/openbmc-flash-layout.dtsi) this change
decreases the free space in the kernel partition from 998,080 bytes to
984,568 bytes.
