* linux-user: Add generic 'termbits.h' for some archsFilip Bozuta2020-08-271-0/+318
| | | | | | | | | | | | | | | | | | | | | This patch introduces a generic 'termbits.h' file for following archs: 'aarch64', 'arm', 'i386, 'm68k', 'microblaze', 'nios2', 'openrisc', 'riscv', 's390x', 'x86_64'. Since all of these archs have the same termios flag values and same ioctl_tty numbers, there is no need for a separate 'termbits.h' file for each one of them. For that reason one generic 'termbits.h' file was added for all of them and an '#include' directive was added for this generic file in every arch 'termbits.h' file. Also, some of the flag values that were missing were added in this generic file so that it matches the generic 'termibts.h' and 'ioctls.h' files from the kernel: 'asm-generic/termbits.h' and 'asm-generic/ioctls.h'.

* linux-user: Introduce TARGET_HAVE_ARCH_STRUCT_FLOCKAleksandar Markovic2019-07-021-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring target_flock definitions to be more in sync with the way flock is defined in kernel. Basically, the rules from the kernel are: 1. Majority of architectures have a common flock definition. 2. Architectures with 32-bit MIPS ABIs have a sligtly different flock definition; those architectures are the only arcitectures that have HAVE_ARCH_STRUCT_FLOCK defined, and that preprocessor constant is used in the common header as a flag for including or not including common flock definition. 3. Sparc architectures also have a sligtly different flock definition, but the difference is only the padding at the end of the structure. The presence of that padding is determined by preprocessor constants __ARCH_FLOCK6_PAD and __ARCH_FLOCK64_PAD. QEMU linux-user already implements rules 1. and 3. in a very similar way as they are implemented in kernel. However, rule 2. is implemented in a dissimilar way (for example, the constant TARGET_HAVE_ARCH_STRUCT_FLOCK is missing), and this patch brings QEMU implementation much closer to the kernel implementation. TARGET_HAVE_ARCH_STRUCT_FLOCK64 constant is also introduced to mimic HAVE_ARCH_STRUCT_FLOCK64 from kernel, but it is not defined anywhere, however, this is the case with HAVE_ARCH_STRUCT_FLOCK64 in kernel as well.
