[Qemu-devel] [PATCH] scripts/update-linux-headers: Handle __aligned_u64 |

We'll currently replace any 'u64' with a 'uint64_t' including when
it's embedded in an '__aligned_u64', creating a '__aligned_uint64_t'
which doesn't exist. We need to instead expand out the kernel's
definition of __aligned_u64:
#define __aligned_u64 __u64 __attribute__((aligned(8)))
before we convert the __u64 to uint64_t.

Alex's "scripts/update-linux-headers: Update handling of __aligned_u64"
patch also addresses this problem, but I think we need to take this
approach, because the resulting header is supposed to be host-OS-portable.
