/*
* If the kernel flag XPRDEBUG is set, the XPR macro is enabled. The
* macro should be invoked something like the following:
* XPR(XPR_SYSCALLS, ("syscall: %d, 0x%x\n", syscallno, arg1);
* which will expand into the following code:
* if (xprflags & XPR_SYSCALLS)
* xpr("syscall: %d, 0x%x\n", syscallno, arg1);
* Xpr will log the pointer to the printf string and up to 6 arguments,
* along with a timestamp and cpuinfo (for multi-processor systems), into
* a circular buffer. The actual printf processing is delayed until after
* the buffer has been collected. It is assumed that the text/data segments
* of the kernel can easily be reconstructed in a post-processor which
* performs the printf processing.
*
* If the XPRDEBUG compilation switch is not set, the XPR macro expands
* to nothing.
