Hi, I wonder if it would be possible to extend foldMemoryOperandImp() so that targets can check for liveness of a particular phys reg? The case I am thinking of is when the new instruction clobbers the CC reg, while the old one did not. In this case the new instruction can only become a replacement if the CC reg is known to be dead. The idea is that liveness of phys regs should be available somehow when this functionis c...

...outputs. So the displayed voltage is not correct -- in fact there should really be THREE voltages displayed, all around 480v. Nut developers: I am copying the NUT mailing list to see if anyone can suggest how to fix this. NUT developers, see the following page to see the problem: http://nemo.phys.uwm.edu/cgi-bin/upsstats.cgi . Instead of displaying a single voltage of 276 VAC we should see three voltages of around 480 VAC.

...During my refresh to latest linux, I noticed, direct mapping of all non-RAM pages in xen_set_identity_and_release(). I currently don''t map all at front, but as needed looking at the PAGE_IO bit in the pte. One result of that is minor change to common code macro: __set_fixmap(idx, phys, PAGE_KERNEL_NOCACHE) to to __set_fixmap(idx, phys, PAGE_KERNEL_IO_NOCACHE) To avoid this change, and keep all my changes limited to xen files only, I thought I could just map the entire non-ram pages up front too. But I am concerned the EPT may grow too large? Specially, when we get to *...
