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.

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> 2014-08-12 20:53:40 +02:00

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> 2014-08-12 20:53:42 +02:00			`#define TARGET_MLOCKALL_MCL_CURRENT 1`
