Building test_vdso_getrandom currently leads to following issue:

Hmm. If I run this on my current 6.10-based system, I get:
$ make CC vdso_standalone_test_x86 CC vdso_test_getrandom vdso_test_getrandom.c:43:41: error: field ‘params’ has incomplete type 43 | struct vgetrandom_opaque_params params; | ^~~~~~
Because KHDR_INCLUDES is /usr/include instead.
Christophe, any suggestions on this one? And any idea why loongarch is hitting it, but not x86 or ppc?
Can you 'make clean' then provide the output of 'make V=1' ?
On powerpc I get:
