(Note that for LP64 sizeof(pthread_mutex_t) \u003e\nsizeof(uintptr_t), so we could potentially clobber other TLS slots too.)\n\nI\u0027ve also rewritten the LP32 compatibility stubs to directly reuse the\ncode from the .h file.\n\nThis reverts commit 75c55ff84ebfa686c7ae2cc8ee431c6a33bd46b4.\n\nBug: 15195455\nChange-Id: I6ffb13e5cf6a35d8f59f692d94192aae9ab4593d\n"
