For sparc64, there does still exist trap 0x111 as tl0_oldlinux64, which was replaced by 0x16d as tl0_linux64 in 1998. Since no one has noticed, don't bother implementing it now.

| | | | | | | | | | | | | | | | | | | | | | | | | 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).

* linux-user: Extract target errno to 'target_errno_defs.h'Philippe Mathieu-Daudé2021-07-122-3/+6
| | | | | | | | | | | | | | | 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'.
