2013-12-17target-arm: Clean up handling of AArch64 PSTATEPeter Maydell
The env->pstate field is a little odd since it doesn't strictly speaking represent an architectural register. However it's convenient for QEMU to use it to hold the various PSTATE architectural bits in the same format the architecture specifies for SPSR registers (since this is the same format the kernel uses for signal handlers and the KVM register). Add some structure to how we deal with it: * document what env->pstate is * add some #defines for various bits in it * add helpers for reading/writing it taking account of caching of NZCV, and use them where appropriate * reset it on startup Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1385645602-18662-3-git-send-email-peter.maydell@linaro.org Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org>

It has been pointed out on LKML that the alpha umount syscall numbers are named wrong, and a patch to rectify that has been posted for 3.11.

2013-09-10linux-user: Allow targets to specify a minimum uname releasePeter Maydell
For newer target architectures, glibc can be picky about the kernel version: for example, it will not run on an aarch64 system unless the kernel reports itself as at least 3.8.0. Accommodate this by enhancing the existing support for faking the kernel version so that each target can optionally specify a minimum version: if the user doesn't force a specific fake version then we will override with the minimum required version only if the real host kernel version is insufficient. Use this facility to let aarch64 report a minimum of 3.8.0. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1378235544-22290-21-git-send-email-peter.maydell@linaro.org
