+- Pick worksize 256 with Cypress if none is specified.
+- Give warning with sdk2.7 and phatk as well.
+- Whitelist sdk2.7 for diablo kernel as well.

+also allowing us to make the output buffer smaller.
+- Remove compile errors/warnings and document compile/usage in FPGA-README
+- bitforce-firmware-flash.c by Luke-jr
+- Ignore the submit_fail flag when deciding whether to recruit more curls or not
+since we have upper bounds on how many curls can be recruited, this test is
+redundant and can lead to problems.
+- API-README update cgminer version number
+- API-README fix groups P: example mistake
+- API-README add COIN and other edits
+- gpu->hit should be reset on new work as well.
