/* This file defines types and constants for the kernel interface, and to
   make that clear everything is prefixed VKI_/vki_.

   All code is copied verbatim from kernel source files, except that:
   - VKI_/vki_ prefixes are added
   - some extra explanatory comments are included;  they are all within
     "[[ ]]"
   - for some types, we only care about the size;  for a few of them (big
     ones that are painful to fully drag in here), a VKI_SIZEOF_* constant
     is used.
   
   The files the code is taken from is indicated.

   Note especially that the types are not the glibc versions, many of which
   are different to those in here. 

   Also note that this file contains all the generic header info, ie. that
   from linux/include/linux/ *.h.  The arch-specific header info, eg. that
   from linux/include/asm-i386/ *.h, is in vki-$PLATFORM.h and
   vki_posixtypes-$PLATFORM.h.  (Two files are required to avoid
   circular dependencies between the generic VKI header and the
   arch-specific VKI header.  It's possible in the future, as more stuff
   gets pulled in, that we might have to split files up some more to avoid
   further circular dependencies.)
   
   Finally, note that it is assumed that __KERNEL__ is set for all these
   definitions, which affects some of them.
*/

/* The structure is (aiui, jrs 20060504):

     #include plat-specific posix types (vki-posixtypes-ARCH-linux.h)

     Lots more types, structs, consts, in this file

     #include other plat-specific stuff (vki-ARCH-linux.h)

     Even more types, structs, consts, in this file

   The system call numbers are dealt with by
   pub_{core,tool}_vkiscnums.h, not via pub_{core,tool}_vki.h, which
   is what this file is part of.
