2023-04-20virt: acrn: Replace obsolete memalign() with posix_memalign()Deming Wang1-3/+2
memalign() is obsolete according to its manpage. Replace memalign() with posix_memalign() and remove malloc.h include that was there for memalign(). As a pointer is passed into posix_memalign(), initialize *p to NULL to silence a warning about the function's return value being used as uninitialized (which is not valid anyway because the error is properly checked before p is returned).

2022-11-23virt: acrn: Mark the uuid field as unusedAndy Shevchenko1-3/+0
After the commits for userspace (see Link tags below) the uuid field is not being used in the ACRN code. Update kernel to reflect these changes, i.e. do the following: - adding a comment explaining that it's not used anymore - replacing the specific type by a raw buffer - updating the example code accordingly The advertised field confused users and actually never been used. So the wrong part here is that kernel puts something which userspace never used and hence this may confuse a reader of this code. Note, that there is only a single tool that had been prepared a year ago for these forthcoming changes in the kernel.
