A few kernel and calling convention adjustments to make sigsend and sigreturn work for arm. . provide a arch_proc_setcontext for earm in kernel . set LR in context of signal handler to provide a proper return address (to __sigreturn) . change __sigreturn to retrieve the sigcontext pointer from the sigframe struct and pass it to _sigreturn() in r0 Change-Id: Icd135a70595382c79d11d8dd9876f6a6f1df41f8
