Oleg Hahm	c2b0423918	core: renamed KERNEL_PID_NULL to KERNEL_PID_UNDEF ... As @authmillenon pointed out the "null" in the old name is somewhat misleading, since the actual value is -1.	2014-08-07 16:31:27 +02:00
Oleg Hahm	983d056c75	core: harmonizes the data type for the process ID ... Instead of using differing integer types use kernel_pid_t for process identifier. This type is introduced in a new header file to avoid circular dependencies.	2014-08-01 12:02:54 +02:00
René Kijewski	abdb3ef2a4	x86: add read-before-write check at runtime ... Finding read-before-writes statically is quite difficult. In native we can use valgrind, but on boards without an MMU we are out of luck. x86 has an MMU, let's use it. If `-DDEBUG_READ_BEFORE_WRITE` was set, then pages on the heap get initialized upon first use. If the page was read before written, then a debug message with the virtual and physical address of the memory location is printed, as well as the address of the offending instruction.	2014-05-31 19:45:19 +02:00
