Use u32 instead of uint32_t to make the KVM selftests code more concise and more similar to the kernel (since selftests are primarily developed by kernel developers). This commit was generated with the following command: git ls-files tools/testing/selftests/kvm | xargs sed -i 's/uint32_t/u32/g' Then by manually adjusting whitespace to make checkpatch.pl happy. No functional change intended.
