I looked in the release notes, but maybe I missed it. Is it not possible to build a kernel from CentOS 4.3 (using 2.6.9-34.0.1) with HIGHMEM support turned off? This is for a machine with 512mb. When I try to build the kernel, I get _etext undefined symbol on line 100 of pageattr.c in arch/i386/mm. Linus

Hi Andrew, This series of patches lays the basic ground work for the paravirtualized kernel patches coming later on. I think this lot is ready for the rough-and-tumble world of the -mm tree. The main change from the last posting is that all the page-table related patches have been moved out, and will be posted separately. Also, the off-by-one in reserving the top of address space has been

Hi Andi, Here's a little batch of cleanups: - re-enable VDSO when PARAVIRT is enabled - make the parainstructions symbols match the other altinstructions naming convention - add kernel command-line options to disable altinstructions for smp and pv_ops Oh, and I'm mailing your noreplacement patch back at you, for no particularly good reason.

I used to have endless trouble with __pow_ii which as I recall could be be fixed by the correct incantation of the mix of compiler libraries and LD_LIBRARY_PATH. It seemed to be extremely sensitive and never easy to get right. The problem is
