For those, see the changelog entries at http://lia64.bkbits.net:8080/to-linus-2.5/ChangeSet@-7d?nav=index.html Summary of other changes: o Rename "McKinley" to "Itanium 2" (only for user-level visible stuff, CONFIG_MCKINLEY will stay). o Offer 64KB page size only for Itanium 2. o Change local_irq_restore() to restore ONLY the psr.i bit. o Add ia64_set_psr() as the new way for setting psr.l. o Perfmon-update from Stephane (sans McKinley support, until the necessary info gets released publically). o Updated Fusion driver (needed for some of HP's zx1 platforms) o Fixed scsi_dma.c to support 64KB page size Some notes/caveats: the 64KB page size seems to work fine on McKinley/Itanium 2 except that "swapon" still hangs for me. I haven't had time to look into this. If you look at the patch, you'll also see that I started merging the "mem_map in virtual memory" patch (CONFIG_VIRTUAL_MEM_MAP), which is currently needed on zx1 platforms with >1GB of memory. However, the merge isn't complete and the new code isn't working yet. If you are one of those lucky folks with such a machine, you'll have to do the following for now: o configure for generic DIG platform (this means you won't get support for the zx1 hardware I/O TLB) o boot with kernel command line option mem=1G (will ignore all memory above 1GB) These issues will get fixed over time, but for now the above should at least give you a working kernel. A slightly earlier version of this patch (without the perfmon update) has been tested on the Ski simulator, Big Sur, and the HP zx1 platform. Enjoy, --david
