Could you please clarify where minmax is needed? I tried to build Jason's master
tree for x86, commenting the header and it seems building fine. I might be
missing something.
Without it:
VDSO32C arch/powerpc/kernel/vdso/vgetrandom-32.o
In file included from /home/chleroy/linux-powerpc/lib/vdso/getrandom.c:11,
from <command-line>:

Same for ARRAY_SIZE(->reserved) by the way, easy to do opencode, we also have it
only once
I have a similar issue to figure out why linux/array_size.h and
uapi/linux/random.h are needed. It seems that I can build the object without
them. Could you please explain?
Without linux/array_size.h:
VDSO32C arch/powerpc/kernel/vdso/vgetrandom-32.o
In file included from <command-line>:
/home/chleroy/linux-powerpc/lib/vdso/getrandom.c: In function
'__cvdso_getrandom_data':
/home/chleroy/linux-powerpc/lib/vdso/getrandom.c:89:40: error: implicit
If this is the case, those headers should be defined for the powerpc
implementation only. The generic implementation should be interpreted as the
minimum common denominator in between all the architectures for what concerns
the headers.
