CONFIG_IMA is a boolean option, so none of these objects is linked
into a module.

All the objects in this directory are compiled only when CONFIG_IMA=y
since this directory is guarded by the parent Makefile:

  obj-$(CONFIG_IMA)                       += ima/

So, there is no point in creating the composite object, ima.o

Flatten the code into the obj-$(CONFIG_...) form.

This patch changes the kernel command line options

	ima.ahash_minsize
	ima.ahash_bufsize

to
	ima_crypto.ahash_minsize
	ima_crypto.ahash_bufsize

Intentional?

Note that these are documented in
Documentation/admin-guide/kernel-parameters.txt.
