It is an extension of GCC CPP to:
* allow omitting a variable macro argument entirely, and
* use ## __VA_ARGS__ to remove the the comma before ## __VA_ARGS__ when
__VA_ARGS__ is empty.
The only use of ## _VA_ARGS__ is to define the pr_xxx() macros, with the first
argument being the format string and the rest the to-be-formatted arguments. The
format string is explicitly spelled out because another macro pr_fmt() is used
to add to the format string a prefix which is customizable by defining what
pr_fmt() expands to.
For C99 compliance, this patch changes the pr_xxx() macros in the following
pattern.
- #define pr_fatal(fmt, ...) \
- do_logmsg(LOG_FATAL, pr_fmt(fmt), ## __VA_ARGS__); \
+ #define pr_fatal(...) \
+ do_logmsg(LOG_FATAL, pr_prefix __VA_ARGS__); \

there are data transfer between guest(GPA) & hv(HPA), especially for
hypercall from guest.
guest should make sure these GPAs are address continous, but hv cannot
assure HPAs which mapped to these GPAs are address continous, for example,
after enable hugetlb, a contious GPA range could come from two different
2M pages.
this patch is handling such case by doing gpa page walking during
copy_from_vm & copy_to_vm.

EDK Shell API is not standard API defined by UEFI spec.
The gnu-efi below v3.0 doesn't support EDK Shell API
(for example, GetShellArgcArgv), that leads to the hypervisor
