It's meant to be pretty stable, not so much a testing ground for new stuff. I'd be very interested in feedback from anyone willing to test on any platform, however large or small. ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/2.5.73/patch-2.5.73-mjb2.bz2 additional patches that can be applied if desired: (these three form the qlogic feral driver) ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.72/2.5.72-mm1/broken-out/linux-isp.patch ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.72/2.5.72-mm1/broken-out/isp-update-1.patch ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.72/2.5.72-mm1/broken-out/isp-remove-pci_detect.patch Since 2.5.73-mjb1 (~ = changed, + = added, - = dropped) Notes: Small release, but upside_down may have large impact. On the other hand, it's very cool, and solves various awkward problems. See if you can break it ;-) Now in Linus' tree: New: + upside_down William Lee Irwin Allocate memory from the top down, shove the stack where it belongs. + node_spanned_pages Dave Hansen Fix up NUMA beancounting Dropped: - numameminfo fix Martin J.
