+=Thread Affinity Mask=
+If the thread is created via a call to SVC 8(CreateThread), which uses thread creation type 3, and the CPU ID is -2(meaning use the core specified in the exheader), the mask is just the affinity mask from the thread's owner KProcess.  If the CPU ID is -1(meaning any core), the affinity mask is set to 0xF on the New3DS and 0x3 on the Old3DS.  Otherwise, the affinity mask is (1 << cpu_id) | 1.
+If the thread is created via a call by the kernel, which uses thread creation types 0-2, the checks for -1 and -2 are skipped and the mask is always (1 << cpu_id) | 1.
