2021-09-23linux-user: Provide new force_sig_fault() functionPeter Maydell
In many places in the linux-user code we need to queue a signal for the guest using the QEMU_SI_FAULT si_type. This requires that the caller sets up and passes us a target_siginfo, including setting the appropriate part of the _sifields union for the si_type. In a number of places the code forgets to set the _sifields union field. Provide a new force_sig_fault() function, which does the same thing as the Linux kernel function of that name -- it takes the signal number, the si_code value and the address to use in _sifields._sigfault, and assembles the target_siginfo itself. This makes the callsites simpler and means it's harder to forget to pass in an address value. We follow force_sig() and the kernel's force_sig_fault() in not requiring the caller to pass in the CPU pointer but always acting on the CPU of the current thread.

2021-09-23linux-user/arm: Use force_sig() to deliver fpa11 emulation SIGFPEPeter Maydell
In the Arm target code, when the fpa11 emulation code tells us we need to send the guest a SIGFPE, we do this with queue_signal(), but we are using the wrong si_type, and we aren't setting the _sifields union members corresponding to either the si_type we are using or the si_type we should be using. As the existing comment notes, the kernel code for this calls the old send_sig() function to deliver the signal. This eventually results in the kernel's signal handling code fabricating a siginfo_t with a SI_KERNEL code and a zero pid and uid. For QEMU this means we need to use QEMU_SI_KILL. We already have a function for that: force_sig() sets up the whole target_siginfo_t the way we need it.
