I'm seeing this build failure for arm64:
    CC [M]  Documentation/filesystems/configfs/configfs_example_macros.o
  In file included from /usr/include/bits/sigcontext.h:27:0,
                   from /usr/include/signal.h:340,
                   from /usr/include/sys/wait.h:30,
                   from Documentation/accounting/getdelays.c:24:
  .../linux/usr/include/asm/sigcontext.h:61:2: error: unknown type name ‘u64’
    u64 esr;
    ^
  make[2]: *** [Documentation/accounting/getdelays] Error 1
This was introduced by commit 15af1942dd:
  arm64: Expose ESR_EL1 information to user when SIGSEGV/SIGBUS
Using __u64 instead of u64 fixes the problem.
