2013-07-22linux-user: Clean up handling of clone() argument orderPeter Maydell
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...)

2013-07-09linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-userPeter Maydell
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.

2013-03-05mipsn32-linux-user: Configure the architecture properlyRichard Henderson
N32 is a 64-bit cpu with a 32-bit address space. We have existing cpp defines for this situation, but weren't using them. This does mean that the linux-user/mipsn32 directory must be merged with the linux-user/mips64 directory, and differences must be resolved via ifdefs.

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>
2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
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.
