mage1	def007e2d7	add #undef for some libc function ... since it's useful to redirect these functions to others sometime(e.g. validate the memory before write). Change-Id: I6253a9231af8809e8362f4bc5a1bd67fb094c3b0	2021-07-14 15:09:58 -03:00

Nathan Hartman	366053e464	Fix typos, 1 in a #define, others in comments. This changes one definition: _MQ_TIMEDRECIEVE is changed to _MQ_TIMEDRECEIVE. It appears this symbol is not used anywhere.	2019-09-11 08:56:56 -06:00

Gregory Nutt	59cc4a7a7b	Protected mode: Redesign how the user space heap is accessed from the kernel code. It used to call memory management functions in user space via function pointers in the userspace interface. That is inefficient because the first thing that those memory management functions do is to trap back into the kernel to get the current PID. Worse, that operation can be fatal is certain fragile situations such as when a task is exitting. ... The solution is to remove all of the memory management function calls from the interface. Instead, the interface exports the userspace heap structure and then kernel size implementations of those memory management functions will operate on the userspace heap structure. This avoids the unnecessary system calls and, more importantly, failures do to freeing memory when a test exits.	2015-07-10 08:37:02 -06:00
