* This file is used by the kernel assembly language sources to provide
* the proper mapping between the global names used in assembly language
* code and the corresponding C symbols. By convention, all C symbols
* that are referenced from assembly language are prefixed with `_'.
* That happens to be the same prefix that the a.out compiler attaches
* to each C symbol.
*
* When using the ELF compiler, C symbols are identical to the corresponding
* assembly language symbols. Thus the extra underscores cause problems.
* The defines in this file map the underscore names back to the proper
* unadorned names.
*
* Every global symbol that is referenced from both C source and assembly
* language source must have an entry in this file, or the kernel will
* not build properly using the ELF compiler.
*
* This file is included by <machine/asmacros.h>, and it is OK to rely
* on that.

Commit major SMP cleanups and move the BGL (big giant lock) in the syscall path inward. A system call may select whether it needs the MP lock or not (the default being that it does need it). A great deal of conditional SMP code for various deadended experiments has been removed. 'cil' and 'cml' have been removed entirely, and the locking around the cpl has been removed. The conditional separately-locked fast-interrupt code has been removed, meaning that interrupts must hold the CPL now (but they pretty much had to anyway). Another reason for doing this is that the original separate-lock for interrupts just doesn't apply to the interrupt thread mechanism being contemplated. Modifications to the cpl may now ONLY occur while holding the MP lock. For example, if an otherwise MP safe syscall needs to mess with the cpl, it must hold the MP lock for the duration and must (as usual) save/restore the cpl in a nested fashion. This is precursor work for the real meat coming later: avoiding having to hold the MP lock for common syscalls and I/O's and interrupt threads. It is expected that the spl mechanisms and new interrupt threading mechanisms will be able to run in tandem, allowing a slow piecemeal transition to occur. This patch should result in a moderate performance improvement due to the considerable amount of code that has been removed from the critical path, especially the simplification of the spl*() calls. The real performance gains will come later. Approved by: jkh Reviewed by: current, bde (exception.s) Some work taken from: luoqi's patch
