Fix copy/paste mistake in kvm_getswapinfo(3) It seems this manpage was copied from kvm_getloadavg(3), but the DIAGNOSTICS section was not updated completely. Update the section with correct information about a return value of -1.

Do not left-shift a negative number (inducing undefined behavior in C/C++) in exp(3), expf(3), expm1(3) and expm1f(3) during intermediate computations that compute the IEEE-754 bit pattern for |2**k| for integer |k|. The implementations of exp(3), expf(3), expm1(3) and expm1f(3) need to compute IEEE-754 bit patterns for 2**k in certain places. (k is an integer and 2**k is exactly representable in IEEE-754.) Currently they do things like 0x3FF0'0000+(k<<20), which is to say they take the bit pattern representing 1 and then add directly to the exponent field to get the desired power of two. This is fine when k is non-negative. But when k<0 (and certain classes of input trigger this), this left-shifts a negative number -- an operation with undefined behavior in C and C++. The desired semantics can be achieved by instead adding the possibly-negative k to the IEEE-754 exponent bias to get the desired exponent field, _then_ shifting that into its proper overall position. (Note that in case of s_expm1.c and s_expm1f.c, there are SET_HIGH_WORD and SET_FLOAT_WORD uses further down in each of these files that perform shift operations involving k, but by these points k's range has been restricted to 2 < k <= 56, and the shift operations under those circumstances can't do anything that would be UB.)

Treat R_X86_64_PLT32 relocs as R_X86_64_PC32. If we load a binary that is designed to be a library, it produces relocatable code via assembler directives in the assembly itself (rather than compiler options). This emits R_X86_64_PLT32 relocations, which are not handled by the kernel linker. Submitted by: gallatin Reviewed by: kib PR: 231451

Without this patch, some CS4614 cards will need users to reload the driver manually or the hardware won't be initialised properly. Something like: # kldload snd_csa # kldunload snd_csa # kldload snd_csa Tested with: Terratec SiXPack 5.1+
