2018-02-25linux-user, m68k: select CPU according to ELF header valuesLaurent Vivier1-0/+6
M680x0 doesn't support the same set of instructions as ColdFire, so we can't use "any" CPU type to execute m68020 instructions. We select CPU type ("m68040" or "any" for ColdFire) according to the ELF header. If we can't, we use by default the value used until now: "any".

2016-07-12linux-user: Clean up target_syscall.h header guardsMarkus Armbruster1-3/+3
Some of them use guard symbol TARGET_SYSCALL_H, but we also have CRIS_SYSCALL_H, MICROBLAZE_SYSCALLS_H, TILEGX_SYSCALLS_H and __UC32_SYSCALL_H__. They all upset scripts/clean-header-guards.pl. Reuse of the same guard symbol TARGET_SYSCALL_H in multiple headers is okay as long as they cannot be included together. The script can't tell, so it warns. The script dislikes the other guard symbols, too. They don't match their file name (they should, to make guard collisions less likely), and __UC32_SYSCALL_H__ is a reserved identifier.

x86, m68k, ppc, sh4 and sparc failed to enable timerfd, because they didn't have timerfd_create system call defined. Instead QEMU defined timerfd syscall. Checking with kernel sources, it appears kernel developers reused timerfd syscall number with timerfd_create, presumably since no userspace called the old syscall number.

Popular glibc based distributions[1] require minimum 2.6.32 as kernel version. For some targets 2.6.18 would be enough, but dropping so low would mean some suboptimal system calls could get used. Set the minimum kernel advertized to 2.6.32 for all architectures but aarch64 to ensure working qemu linux-user in case host kernel is older.
