So now I humbly request the assistance of a larger userbase in testing the bootmem patch. The bootmem subsystem is used for tracking and reserving usable physical memory during early boot. A patch such as this, which tracks extents explicitly, was requested by several people. The patch is also intended to improve discontiguous memory support in that subsystem. The only user-visible effect of the patch should be to save small amounts of memory by virtue of somewhat more accurate tracking of the boundaries of allocated regions, on the order of 4-12KB on i386. The patch has been tested successfully on i386, IA64, mipsel, Super-H, ppc64, sparc64, and sparc32, when applied against 2.4.15. The patch (against various kernel versions) is available from ftp://ftp.kernel.org/pub/linux/kernel/people/wli/bootmem/ Those using the 2.4.15 patch will need to apply overflow-2.4.15 in addition to bootmem-2.4.15 Thanks, Bill
