Markus Armbruster	3500385697	linux-user: Clean up target_structs.h header guards These headers all use TARGET_STRUCTS_H as header guard symbol. Reuse of the same guard symbol in multiple headers is okay as long as they cannot be included together. Since we can avoid guard symbol reuse easily, do so: use guard symbol $target_TARGET_STRUCTS_H for linux-user/$target/target_structs.h.

Markus Armbruster	3622634bc6	linux-user: Clean up target_syscall.h header guards 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. Clean them all up: use guard symbol $target_TARGET_SYSCALL_H for linux-user/$target/target_sycall.h.

Lluís Vilanova	460c579f3d	build: [linux-user] Rename "syscall.h" to "target_syscall.h" in target directories This fixes double-definitions in linux-user builds when using the UST tracing backend (which indirectly includes the system's "syscall.h").

Tom Musta	6f6a40328b	linux-user: Support target-to-host translation of mlockall argument The argument to the mlockall system call is not necessarily the same on all platforms and thus may require translation prior to passing to the host. For example, PowerPC 64 bit platforms define values for MCL_CURRENT (0x2000) and MCL_FUTURE (0x4000) which are different from Intel platforms (0x1 and 0x2, respectively) Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>	12 years ago

Riku Voipio	cbc14e6f28	linux-user: set minimum kernel version to 2.6.32 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.

Peter Maydell	6291ad77d7	linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-user The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU related -- they are specific to the TLS ABI for a a particular OS. Move them into the linux-user/ tree where they belong. target-lm32 had entirely unused implementations, since it has no linux-user target; just drop them.

Peter Maydell	24c35a504e	linux-user: Merge pread/pwrite into pread64/pwrite64 The Linux syscalls underlying pread() and pwrite() take a 64 bit offset on all architectures, even if some of them name the syscall "pread/pwrite" rather than "pread64/pwrite64" for historical reasons. So move the four QEMU target architectures (arm, i386, sparc, unicore32) which were defining TARGET_NR_pread/pwrite to define TARGET_NR_pread64/pwrite64 instead, and drop the TARGET_NR_pread/pwrite implementation code completely. (Based on examination of the kernel sources for the four architectures this patch affects.)
