Ben Gras	3eeff022fb	Added function read_cpu_flags() that returns current cpu flags as a ... long. This is used to check for interrupts being disabled at the time of a lock() call, if enabled in config.h. The number of times this happens is then counted in the kinfo structure. These events (recursive lockings) lead to nasty race conditions.	2005-06-20 14:53:13 +00:00
Ben Gras	c977bd8709	Added args to lock() and unlock() to tell them apart, for use ... when lock timing is enabled in minix/config.h. Added phys_zero() routine to klib386.s that zeroes a range of memory, and added corresponding system call.	2005-06-01 09:37:52 +00:00
