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.

Riku Voipio	4fc4732047	linux-user: sync syscall numbers upto 3.13 All others updated except unicore, which doesn't look right to begin with. Signed-off-by: Riku Voipio <riku.voipio@linaro.org>	12 years ago
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	4ce6243dc6	linux-user: Clean up handling of clone() argument order Linux manages to have three separate orderings of the arguments to the clone() syscall on different architectures. In the kernel these are selected via CONFIG_CLONE_BACKWARDS and CONFIG_CLONE_BACKWARDS2. Clean up our implementation of this to use similar #define names rather than a TARGET_* ifdef ladder. This includes behaviour changes fixing bugs on cris, x86-64, m68k, openrisc and unicore32. cris had explicit but wrong handling; the others were just incorrectly using QEMU's default, which happened to be the equivalent of CONFIG_CLONE_BACKWARDS. (unicore32 appears to be broken in the mainline kernel in that it tries to use arg3 for both parent_tidptr and newtls simultaneously -- we don't attempt to emulate this bug...)

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.

Anthony Liguori	c227f0995e	Revert "Get rid of _t suffix" In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit `99a0949b72`.
