2022-09-27linux-user: Provide MADV_* definitionsIlya Leoshkevich
Provide MADV_* definitions using target_mman.h header, similar to what kernel does. Most architectures use the same values, with the exception of alpha and hppa.

2022-01-06linux-user: Split out do_prctl and subroutinesRichard Henderson
Since the prctl constants are supposed to be generic, supply any that are not provided by the host. Split out subroutines for PR_GET_FP_MODE, PR_SET_FP_MODE, PR_GET_VL, PR_SET_VL, PR_RESET_KEYS, PR_SET_TAGGED_ADDR_CTRL, PR_GET_TAGGED_ADDR_CTRL. Return EINVAL for guests that do not support these options rather than pass them on to the host.

The qemu-common.h header is not supposed to be included from any other header files, only from .c files (as documented in a comment at the start of it). Move the include to linux-user/hexagon/cpu_loop.c, which needs it for the declaration of cpu_exec_step_atomic().

2021-09-13linux-user: Split linux-user internals out of qemu.hPeter Maydell
qemu.h is included in various non-linux-user files (which mostly want the TaskState struct and the functions for doing usermode access to guest addresses like lock_user(), unlock_user(), get_user*(), etc). Split out the parts that are only used in linux-user itself into a new user-internals.h. This leaves qemu.h with basically three things: * the definition of the TaskState struct * the user-access functions and macros * do_brk() all of which are needed by code outside linux-user that includes qemu.h. The addition of all the extra #include lines was done with sed -i '/include.*qemu\.h/a #include "user-internals.h"' $(git grep -l 'include.*qemu\.h' linux-user) (and then undoing the change to fpa11.h).

2021-07-12linux-user: Extract target errno to 'target_errno_defs.h'Philippe Mathieu-Daudé
We want to access the target errno indepently of the rest of the linux-user code. Move the header containing the generic errno definitions ('errno_defs.h') to 'generic/target_errno_defs.h', create a new 'target_errno_defs.h' in each target which itself includes 'generic/target_errno_defs.h'.

2021-05-15linux-user: Pass CPUArchState to target_restore_altstackRichard Henderson
In most cases we were already passing get_sp_from_cpustate directly to the function. In other cases, we were passing a local variable which already contained the same value. In the rest of the cases, we were passing the stack pointer out of env directly.
