I have also fixed a few bugs in guest_access.h
Do you think you could split those out as a diff to
xen/include/asm-powerpc/guest_access.h, to be applied before we
move it?
Here is the patch.
your patch inlined below, does not do anything other than rename
_x,_y to _d,_s.. am I missing something?
Yes. See below.
#define __copy_field_to_guest(hnd, ptr, field)
({ \
- const int _off = offsetof(typeof(*ptr),
field); \
- const typeof(&(ptr)->field) _x = &(hnd).p-
>field; \
- const typeof(&(ptr)->field) _y = &(ptr)-
>field; \
- xencomm_copy_to_guest(_x, _y, sizeof(*_x), sizeof(*_x)*
(_off)); \
+ const int _off = offsetof(typeof(*ptr),
field); \
+ const typeof(ptr) _d =
(hnd).p; \
+ const typeof(&(ptr)->field) _s = &(ptr)-
>field; \
+ xencomm_copy_to_guest(_d, _s, sizeof(*_s), _off); \
Cf how _x/_d are declared and the parameters of xencomm_copy_to_guest.
#define __copy_field_from_guest(ptr, hnd, field)
({ \
const int _off = offsetof(typeof(*ptr),
field); \
- const typeof(&(ptr)->field) _x = &(hnd).p-
>field; \
- const typeof(&(ptr)->field) _y = &(ptr)-
>field; \
- xencomm_copy_to_guest(_y, _x, sizeof(*_x), sizeof(*_x)*
(_off)); \
+ const typeof(ptr) _s =
(hnd).p; \
+ const typeof(&(ptr)->field) _d = &(ptr)-
>field; \
+ xencomm_copy_from_guest(_d, _s, sizeof(*_d), _off); \
Idem.
Tristan.
