227 6911 d 6 h jermar /SPARTAN/trunk/ Add couple of assertions CPU != NULL.

Change type of nrdy from int to count_t.

Rewrite halt() to avoid page fault when CPU == NULL.		  
226 6911 d 6 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
223 6911 d 11 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.		  
221 6911 d 12 h jermar /SPARTAN/trunk/ Preemption work.
Define PREEMPTION_DISABLED macro.
This macro determines the level of preemptivity (0 = preemption enabled, THE->preemption_disabled = no preemption inside spinlock, 1 = preemption disabled).
Reformulate preemption code in clock.c to consider PREEMPTION_DISABLED.		  
220 6911 d 12 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
219 6911 d 20 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.		  
216 6911 d 21 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
214 6911 d 23 h vana /SPARTAN/trunk/src/  
213 6911 d 23 h jermar /SPARTAN/trunk/ Add some comments.  
212 6911 d 23 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
210 6911 d 23 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
208 6912 d 8 h palkovsky /SPARTAN/trunk/ arch_pre_init_mm now working.  
207 6912 d 9 h decky /SPARTAN/trunk/ separated stack mapping  
206 6912 d 10 h palkovsky /SPARTAN/trunk/ Better types for ia32 drivers, so that they can be reused in amd64.
Build script cleanup amd64.
New code / not working yet / in amd64.		  
205 6912 d 11 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().		  
202 6912 d 22 h palkovsky /SPARTAN/trunk/src/lib/ Fixed bad types in memsetw.  
200 6912 d 23 h palkovsky /SPARTAN/trunk/ Added putchar to AMD  
198 6912 d 23 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
197 6913 d 1 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
195 6913 d 1 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option
