[PATCH v2 19/23] exec/user: Do not include 'cpu.h' in 'abitypes.h'

Posted by Philippe Mathieu-Daudé 1 year, 11 months ago

"exec/user/abitypes.h" requires:

 - "exec/cpu-defs.h"           (TARGET_LONG_BITS)
 - "exec/tswap.h"              (tswap32)

In order to avoid "cpu.h", pick the minimum required headers.

Assert this user-specific header is only included from user
emulation.
