Hello,

# [GNU-767] Support changing SVE vector length in remote debugging

* Found and fixed problem with the gdbserver prototype: it didn't clear the registers cache when the target description changed. The prototype is working now. * Turned my attention to the testsuite regressions introduced by my changes. Fixed one where gdbserver was crashing when debugging multi-threaded programs, and now investigating one where gdbserver returns an error when handling the ‘vRun’ remote protocol packet.

# Misc

* Public holiday on Thursday — but I took it on Friday instead.
