I suppose we could add a page at a fixed virtual offset from the vDSO base address. That would make the code sequence easier since we would presumably could use PC-relative addressing in the vDSO code. This would be much better than having a fixed virtual address. I'm just worried about the overhead of having an extra page per thread to store 32 bits.
slightly dangerous, but how about reserving a few bytes above stack? Richard - To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
