H. Peter Anvin 1838ef1d78 x86-64, rwsem: 64-bit xadd rwsem implementation ... For x86-64, 32767 threads really is not enough. Change rwsem_count_t to a signed long, so that it is 64 bits on x86-64. This required the following changes to the assembly code: a) %z0 doesn't work on all versions of gcc! At least gcc 4.4.2 as shipped with Fedora 12 emits "ll" not "q" for 64 bits, even for integer operands. Newer gccs apparently do this correctly, but avoid this problem by using the _ASM_ macros instead of %z. b) 64 bits immediates are only allowed in "movq $imm,%reg" constructs... no others. Change some of the constraints to "e", and fix the one case where we would have had to use an invalid immediate -- in that case, we only care about the upper half anyway, so just access the upper half.
