The target_semid_ds structure is not correct for all architectures: the padding fields should only exist for: * 32-bit ABIs * x86 It is also misnamed, since it is following the kernel semid64_ds structure (QEMU doesn't support the legacy semid_ds structure at all). Rename the struct, provide a correct generic definition and allow the oddball x86 architecture to provide its own version. This fixes broken SYSV semaphores for all our 64-bit architectures except x86 and ppc. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
