r366302 broke copy_file_range(2) for small values of input file offset and len. It was possible for rem to be greater than len and then "len - rem" was a large value, since both variables are unsigned.

This flag has been set on startup since 65618fdda0f272a823e6701966421bdca0efa301. However, This causes some of the math-related tests to fail as they report zero instead of a tiny number. This fixes at least /usr/tests/lib/msun/ldexp_test and possibly others. Additionally, setting this flag prevents printf() from printing subnormal numbers in decimal form.

|874635e3||mhorne||March 1, 2021, 2:04 p.m.||arm64: fix hardware single-stepping from EL1
The main issue is that debug exceptions must to be disabled for the entire duration that SS bit in MDSCR_EL1 is set. Otherwise, a single-step exception will be generated immediately. This can occur before returning from the debugger (when MDSCR is written to) or before re-entering it after the single-step (when debug exceptions are unmasked in the exception handler). Solve this by delaying the unmask to C code for EL1, and avoid unmasking at all while handling debug exceptions, thus avoiding any recursive debug traps.

|524b018d||arichardson||March 1, 2021, 12:53 p.m.||riscv: Add a soft-float implementation of fabs()
We could just use a C implementation using __builtin_fabs(), but using this assembly version guarantees that there is no additional prolog/epilog code. Additionally, clang generates worse code for masking off the top bit than GCC: https://bugs.llvm.org/show_bug.cgi?id=49377. This fixes the RISCV64 softfloat world build after cf97d2a1dab8. That commit added -fno-builtin to the msun tests which resulted in the first references to fabs (previously the compiler inlined all calls).
