Should this condition also include KEEP_DECOMPRESSOR?

In kernel/Kconfig.kexec, KEXEC_BPF has:

    depends on DEBUG_INFO_BTF && BPF_SYSCALL && KEEP_DECOMPRESSOR

Since Kconfig's select statement forces a symbol's value without visiting
the dependencies, this select will enable KEXEC_BPF even when
KEEP_DECOMPRESSOR is not set, creating an inconsistent configuration.

KEEP_DECOMPRESSOR defaults to n and nothing selects it, so this appears
to be a missing condition in the select statement.
