PAE mode is enabled with HIGHMEM64, which is (apparently) extremely slow. Is it possible to give some other way to get the hardware NX bit working in 32-bit mode, without the apparently massive performance penalty of HIGHMEM64? - -- We will enslave their women, eat their children and rape their cattle! -- Bosc, Evil alien overlord from the fifth dimension -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQIVAwUBRXsfAAs1xW0HCTEFAQIb3xAAhuVgOGGff6N3BQFUjej6PozDDcc56C2P pS+6JOdUaFWNfBbBg9FWbeGkW8thwNOfRRaTgE3TXar44djwd8rmjfFx9siWenue sYbdn61LYWsTRsRuS3noD49Dn3vj/sOv8pPEiz6ZPYd3kgkuipQHNVWUUjR7mne/ 9o5P4ajae4gcml7z3CcQVO8CkCFpCqQUPwXz2yVBPGEi4DEJHrNIlr8mbP2uBPkD nXcMY5KmHovDyueihoaVInzBdIhNGUSFEc6mfZS0bluCLaNUudWJCZDjEwunHS7M ngySKIQC2U3I0tgdok00Szum2NRlwclDNpoQP4x9577v/rCTVKfOxv+CioK+DXG2 QnYBPuicI31f2++itubnidLgCiBtjbuwHaz0OMMg9Ix7xws4WX2BLykuenRAxN9f F+TZuJJq8sD1CfTveomZq7UP8mpBECXB+HRTMNdpIy+QJ19Eg8p4N/l2pep1hvDv UA6tafSopIXEzcQKQ6Yi1MI8Du79O1zpTWzS+Hwgl+t3XfkI2e04wq7D4aN2ZMlw b3S3h6Lp4I9EgqPLBnu+s2/AkRa/AxZc3eGbgf8Fz75sbDYvRnuhXzSxAmmJru5D d51uB0GuHbiser+axWIj886pAOLPa2KGYpAjm7gtmVWFBNhzx5gnQRJkrxIcg4ew JOb4VR4yfB8= =QCVY -----END PGP SIGNATURE----- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
