per-page execution right was disabled (therefore leading to the inability of the kernel to detect fraudulent use of memory mappings marked as not being executable). - replace cpu_feature and ci_feature_flags variables by cpu_feature and ci_feat_val arrays. This makes it cleaner and brings kernel code closer to the design of cpuctl(8). A warning will be raised for each CPU that does not expose the same features as the Boot Processor (BP). - the blacklist of CPU features is now a macro defined in the specialreg.h header, instead of hardcoding it inside MD initialization code; fix comments. - replace checks against CPUID_TSC with the cpu_hascounter() function. - clean up the code in init_x86_64(), as cpu_feature variables are set inside cpu_probe(). - use cpu_init_msrs() for i386. It will be eventually used later for NX feature under i386 PAE kernels. - remove code that checks for CPUID_NOX in amd64 mptramp.S, this is already performed by cpu_hatch() through cpu_init_msrs(). - remove cpu_signature and feature_flags members from struct mpbios_proc (they were never used). This patch was tested with i386 MONOLITHIC, XEN3PAE_DOM0 and XEN3_DOM0 under a native i386 host, and amd64 GENERIC, XEN3_DOM0 via QEMU virtual machines. XXX Should kernel rev be bumped? XXX A similar patch should be pulled-up for NetBSD-5, hopefully tomorrow. |
