最後變更在這個檔案從30092是 29250,由 vboxsync 提交於 15 年前
iprt/asm.h: split out asm-math.h, don't include asm-.h from asm.h, don't include asm.h from sup.h. Fixed a couple file headers.

19	*
20	* The CPU Monitor / Manager keeps track of all the CPU registers. It is
21	* also responsible for lazy FPU handling and some of the context loading
22	* in raw mode.
23	*
24	* There are three CPU contexts, the most important one is the guest one (GC).
25	* When running in raw-mode (RC) there is a special hyper context for the VMM
26	* part that floats around inside the guest address space. When running in
27	* raw-mode, CPUM also maintains a host context for saving and restoring
28	* registers accross world switches. This latter is done in cooperation with the
29	* world switcher (@see pg_vmm).
30	*
