-- fe689b30f9a3a614e8a577997cc340043d01c2f1 by Abseil Team <absl-team@google.com>: Change arm32 linux backtrace to use the generic implementation. PiperOrigin-RevId: 218386158 -- 86f8678d055d32edc989e6a4d1dc49c3a15cd350 by Abseil Team <absl-team@google.com>: Update documentation on SHARED_LOCKS_REQUIRED and EXCLUSIVE_LOCKS_REQUIRED so that users know the differences between them. PiperOrigin-RevId: 218365545 -- 22947b48ce4a1ba71ad4794f762235dac3a1df12 by Greg Falcon <gfalcon@google.com>: The from_chars implementation incorrectly assumed `uint32_t` was `unsigned int`. `strings_internal::BigUnsigned` had `uint32_t` and `uint64_t` constructors; when both of these types differ from `unsigned int`, `BigUnsigned(1u)` is ambiguous (neither conversion is better). Fix this by removing the `uint32_t` constructor. When the `uint64_t` constructor is called with a literal or type that is 32 bits or narrower, the compiler is smart enough to optimize away the two-word case, so this fix is free. PiperOrigin-RevId: 218346935 -- 7201ab430bb90ca0e30b102915d02564f61353eb by Abseil Team <absl-team@google.com>: Fix formatting errors discovered during merge conflict.
