Fix CVE-2009-3767.
[lukem, ticket #1374]
+sys/arch/amd64/amd64/locore.S 1.56
+
+ When kernel remaps to high memory in amd64 locore, the GDT used
+ before becomes invalid. As such, split it in two parts, one for
+ use when system boots in low memory, and one for use when it jumps
+ to high memory.
+ [jym, ticket #1376]
+
+sys/arch/x86/x86/identcpu.c 1.19
+
+ Fix a test semantic in cpu_probe(): check that the CPU currently
+ probed is the first one booting by comparing its struct cpu_info
+ address with cpu_info_primary, rather than supposing that
+ cpu_feature variables are set to 0.

+ Fix the NX regression issue observed on amd64 kernels, where
+ 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).
