Fix qemu endless loop when raising a SIGSEGV/SIGBUS signal with gdbstub in user emulation
When a SIGSEGV signal is raised in user mode emulation the current test to know whether the signal is sent by the kernel is wrong : info->si_code == SI_KERNEL according to /usr/include/bits/siginfo.h it should be info->si_code > 0 Signed-off-by: Lionel Landwerlin <lionel.landwerlin@openwide.fr> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6151 c046a42c-6fe2-441c-8c8c-71466251a162
