In this case, the address is a runtime constant, so at - * the very least we can patch the call to e a simple direct call, or - * ideally, patch an inline implementation into the callsite. (Direct - * calls are essentially free, because the call and return addresses - * are completely predictable.) - * - * For i386, these macros rely on the standard gcc "regparm(3)" calling - * convention, in which the first three arguments are placed in %eax, - * %edx, %ecx (in that order), and the remaining arguments are placed - * on the stack. All caller-save registers (eax,edx,ecx) are expected - * to be modified (either clobbered or used for return values). - * X86_64, on the other hand, already specifies a register-based calling - * conventions, returning at %rax, with parameteres going on %rdi, %rsi, - * %rdx, and %rcx. Note that for this reason, x86_64 does not need any - * special handling for dealing with 4 arguments, unlike i386. - * However, x86_64 also have to clobber all caller saved registers, which - * unfortunately, are quite a bit (r8 - r11) - * - * The call instruction itself is marked by placing its start address - * and size into the .parainstructions section, so that - * apply_paravirt() in arch/i386/kernel/alternative.c can do the - * appropriate patching under the control of the backend pv_init_ops - * implementation. - * - * Unfortunately there's no way to get gcc to generate the args setup - * for the call, and then allow the call itself to be generated by an - * inline asm. Because of this, we must do the complete arg setup and - * return value handling from within these macros. This is fairly - * cumbersome. - * - * There are 5 sets of PVOP_* macros for dealing with 0-4 arguments. - * It could be extended to more arguments, but there would be little - * to be gained from that. For each number of arguments, there are - * the two VCALL and CALL variants for void and non-void functions. - * - * When there is a return value, the invoker of the macro must specify - * the return type. The macro then uses sizeof() on that type to - * determine whether its a 32 or 64 bit value, and places the return - * in the right register(s) (just %eax for 32-bit, and %edx:%eax for - * 64-bit). For x86_64 machines, it just returns at %rax regardless of - * the return value size. - * - * 64-bit arguments are passed as a pair of adjacent 32-bit arguments - * i386 also passes 64-bit arguments as a pair of adjacent 32-bit arguments - * in low,high order - * - * Small structures are passed and returned in registers. The macro - * calling convention can't directly deal with this, so the wrapper - * functions must do this. - * - * These PVOP_* macros are only defined within this header. This - * means that all uses must be wrapped in inline functions.
