mini-os: C programming
2 questions on the code of mini-os (the one in XEN 3.0.3):
1. In xen-3.0.3/extras/mini-os/mm.c:52 is a declaration of stack
extern char *stack;
but in file xen-3.0.3/extras/mini-os/arch/x86/setup.c:48, there is also
a decl of stack:
char stack[8192];
If one dereferences the variable stack, which is apparently not the case
yet, it gives surely a segfault!

hvm_init_ap_contexts

int vcpuid, int trampoline_vector)
{
return hvm_funcs.init_ap_context(ctxt, vcpuid, trampoline_vector);
}

x86_64 platform : addresses type
Several addresses are actually on 32 bits, such as in
typedef struct {
u32 flags;
u32 mem_lower;
u32 mem_upper;
u32 boot_device;
u32 cmdline;
u32 mods_count;
u32 mods_addr;
union {
aout_symbol_table_t aout_sym;
elf_section_header_table_t elf_sec;
} u;
u32 mmap_length;
u32 mmap_addr;
} multiboot_info_t
However, on x86_64 using gcc,
