This very small patch:
introduces a new warning when compiling the -mm kernel:

.../linux-2.6.24-rc6-mm1/ipc/msg.c: In function `do_msgrcv':
.../linux-2.6.24-rc6-mm1/ipc/msg.c:939: warning: comparison of distinct pointer
types lacks a cast

I don't know if doing in include/linux/msg.h

struct msg_msg {
	struct list_head m_list;
	long  m_type;
-	int m_ts;           /* message text size */
+	size_t m_ts;           /* message text size */
	struct msg_msgseg* next;
	void *security;
	/* the actual message follows immediately */

is acceptable ?

Otherwise, either a cast can be added or this patch can be dropped...
