KVM: selftests: Silence compiler warning in the kvm_page_table_test
[ Upstream commit 266a19a0bc4fbfab4d981a47640ca98972a01865 ]
When compiling kvm_page_table_test.c, I get this compiler warning
with gcc 11.2:
kvm_page_table_test.c: In function 'pre_init_before_test':
../../../../tools/include/linux/kernel.h:44:24: warning: comparison of
distinct pointer types lacks a cast
44 | (void) (&_max1 == &_max2); \
| ^~
kvm_page_table_test.c:281:21: note: in expansion of macro 'max'
281 | alignment = max(0x100000, alignment);
| ^~~
Fix it by adjusting the type of the absolute value.
