* linux-user: Clean up handling of clone() argument orderPeter Maydell2013-07-221-0/+7
| | | | | | | | | | | | | | | | | | | 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...)

* linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-userPeter Maydell2013-07-091-0/+1
| | | | | | | | | | | | | 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.

* linux-user: Add syscall numbers from kernel 2.6.39.2Peter Maydell2011-07-111-0/+12
| | | | | | | | Add syscall numbers for new syscall numbers; this brings us into line with Linux 2.6.39.2. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
* Revert "Get rid of _t suffix"Anthony Liguori2009-10-011-1/+1
| | | | | | | | | | | | 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 99a0949b720a0936da2052cb9a46db04ffc6db29.
