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.
