Hi Sam,

Today's linux-next build (x86_64 allmodconfig) failed like this:

In file included from arch/x86/kernel/syscall_64.c:28:
arch/x86/include/asm/unistd_64.h:665: error: array index in initializer exceeds array bounds
arch/x86/include/asm/unistd_64.h:665: error: (near initialization for 'sys_call_table')
arch/x86/include/asm/unistd_64.h:665: warning: excess elements in array initializer
arch/x86/include/asm/unistd_64.h:665: warning: (near initialization for 'sys_call_table')

Exposed by commit a2e2725541fad72416326798c2d7fa4dafb7d337 ("net:
Introduce recvmmsg socket syscall").  include/asm/asm-offsets.h did not
get updated even though arch/x86/kernel/asm-offsets.s did.  Ah,
generated/asm-offsets.h has been updated but my build tree still has the
(generated in a previous build) include/asm/asm-offsets.h which is
presumably found before the new arch/x86/include/asm/asm-offsets.h
introduced by commit fe5ff47a5d79ca99ec7e3155eb19469b44905b2c ("kbuild:
move asm-offsets.h to include/generated").

Sam, can you think of a better migration path?

I removed include/asm/asm_offsets.h from my object tree and everything
builds ok.
