  "message": "kernel/arch: optimize memory use of some thread fields\n\nSome thread fields were 32-bit wide, when they are not even close to\nusing that full range of values. They are instead changed to 8-bit fields.\n\n- prio can fit in one byte, limiting the priorities range to -128 to 127\n\n- recursive scheduler locking can be limited to 255; a rollover results\n  most probably from a logic error\n\n- flags are split into execution flags and thread states; 8 bits is\n  enough for each of them currently, with at worst two states and four\n  flags to spare (on x86, on other archs, there are six flags to spare)\n\nDoing this saves 8 bytes per stack. It also sets up an incoming\nenhancement when checking if the current thread is preemptible on\ninterrupt exit.\n\nChange-Id: Ieb5321a5b99f99173b0605dd4a193c3bc7ddabf4\nSigned-off-by: Benjamin Walsh \u003cbenjamin.walsh@windriver.com\u003e\n",
