I'm seeing this build failure for arm64:

This was introduced by commit 15af1942dd61ee23:
arm64: Expose ESR_EL1 information to user when SIGSEGV/SIGBUS
Using __u64 instead of u64 fixes the problem.

This information is useful for instruction emulators to detect
read/write and access size without having to decode the faulting
instruction. The current patch exports it via sigcontext (struct
esr_context) and is only valid for SIGSEGV and SIGBUS.
