Thanks, that is very interesting... I noticed that there are no reserved pages. There *must* be some pages marked as reserved for the bios somewhere right? Also how do you tell what pages are free or allocated to the kernel? It seems that free pages sometimes have the buddy bit set and sometimes not, and pages used by the slab cache sometimes have the slab bit set, and sometimes not. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJTkMYcAAoJEI5FoCIzSKrwq28H/18Y/O+u/ZTT7ICVvUUjM5YP LNb43Nf/7uvaE/ElMiemGdzqSzUcf4wb93HtVeV3OmuV/ALk1H/eaYFLpxxq1sGI hXojGoqaHUwHTie//3Xq3C4Dfi0jDqC7tTX6uywSDRdCzbq2TOGuruc+0n0k3r7b MCQC+Vqr+mzW0d8U8EVE6ux8noA9FlUMFdNDTJAMEbZiyfKdjFXCua4lnVPope/h yB3M4Th+eYY6YGvPoEPfJeYSdeqNGwW2JH6zRGokVk7i21D1G8vudMmwMYziso5D YmTeLvrLhQw3tnX1O0Y7MKepRabx9vqhbruK+5RzTQYl1UZYZEnZ3NO6ithC+UU= =bkUL -----END PGP SIGNATURE----- -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
