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
Tom Musta	0903c8be9e	linux-user: Minimum Sig Handler Stack Size for PPC64 ELF V2 The ELF V2 ABI for PPC64 defines MINSIGSTKSZ as 4096 bytes whereas it was 2048 previously. 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.

Petar Jovanovic	55a2b1631f	linux-user: create target_structs header to place ipc_perm and shmid_ds Creating target_structs header in linux-user/$arch/ and making target_ipc_perm and target_shmid_ds its first inhabitants. The struct defintions may/should be further fine-tuned by arch maintainers.

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.)
