Don't use Linux kernel internal types like u32, __u32 or __le32.
-Use target_phys_addr_t for guest physical addresses except pcibus_t
+Use hwaddr for guest physical addresses except pcibus_t
for PCI addresses. In addition, ram_addr_t is a QEMU internal address
space that maps guest RAM physical addresses into an intermediate
address space that can map to host virtual address spaces. Generally

-Do not use the strncpy function. According to the man page, it does
-*not* guarantee a NULL-terminated buffer, which makes it extremely dangerous
-to use. Instead, use functionally equivalent function:
-void pstrcpy(char *buf, int buf_size, const char *str)
+Do not use the strncpy function. As mentioned in the man page, it does *not*
+guarantee a NULL-terminated buffer, which makes it extremely dangerous to use.
+It also zeros trailing destination bytes out to the specified length. Instead,
+use this similar function when possible, but note its different signature:
+void pstrcpy(char *dest, int dest_buf_size, const char *src)
Don't use strcat because it can't check for buffer overflows, but:
char *pstrcat(char *buf, int buf_size, const char *s)
