4607177383 replace pending_intr with pending_req
the pending_intr is not only serving for interrupt but also for different
request including TLB & TMR updating, so change the function & variants
name accordingly.

16152fad79 HV: debug: stop using ## __VA_ARGS__
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__);		\

004d2e2696 HV: treewide: give names to unnamed structs/unions
According to the syntax defined in C99, each struct/union field must have an
identifier. This patch adds names to the previously unnamed fields for C99
compatibility.

Here is a summary of the names (marked with a pair of *stars*) added.

struct trusty_mem:

    union {
        struct {
            struct key_info key_info;
            struct trusty_startup_param startup_param;
        } *data*;
        uint8_t page[CPU_PAGE_SIZE];
    } first_page;

struct ptdev_remapping_info:

    union {
        struct ptdev_msi_info msi;
        struct ptdev_intx_info intx;
    } *ptdev_intr_info*;

union code_segment_descriptor:

    uint64_t value;
    struct {
        union {
            ...
        } low32;
        union {
            ...
        } high32;
    } *fields*;

    similar changes are made to the following structures.
    * union data_segment_descriptor,
    * union system_segment_descriptor,
    * union tss_64_descriptor, and
    * union idt_64_descriptor

struct trace_entry:

    union {
        struct {
            uint32_t a, b, c, d;
        } *fields_32*;
        struct {
            uint8_t a1, a2, a3, a4;
            uint8_t b1, b2, b3, b4;
            uint8_t c1, c2, c3, c4;
            uint8_t d1, d2, d3, d4;
        } *fields_8*;
        struct {
            uint64_t e;
            uint64_t f;
        } *fields_64*;
        char str[16];
    } *payload*;

ef3cb5ba1c treewide: remove unnecessary unnamed structs/unions
According to the syntax defined in C99, each struct/union field must have an
identifier. This patch removes unnamed struct/union fields that can be easily
expressed in a C99-compatible way.

Here is a summary of structs/unions removed.

struct vhm_request:

    union {
        uint32_t type;                  uint32_t type;
        int32_t reserved0[16];    =>    int32_t reserved0[15];
    };

struct vhm_request_buffer:

    struct vhm_request_buffer {
        union {                         union vhm_request_buffer {
            struct vhm_request ...; =>        struct vhm_request ...;
            int8_t reserved[4096];            int8_t reserved[4096];
        }                               }

2ff7bf826e page walk during copy_from_vm/copy_to_vm
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.
