This is a direct commit to stable/13 as mips no longer exists in main.

After it was introduced, but before those bugs were addressed, mips support was dropped from head, so those mips bugs were never fixed in head. Now, that change and those fixes have been merged into stable/13. This change fixes two of those bugs that were fixed everywhere else but never in mips.

Define them in vm_extern.h and use them where possible where vm_extern.h is included.

Add PT_GETREGSET 2022-05-12T22:12:59Z Andrew Turner andrew@FreeBSD.org 2022-01-24T11:24:17Z urn:sha1:658631a37d78c9ea5debe4642630c7154b86bcd6 This adds the PT_GETREGSET and PT_SETREGSET ptrace types. These can be used to access all the registers from a specified core dump note type. The NT_PRSTATUS and NT_FPREGSET notes are initially supported. Other machine-dependant types are expected to be added in the future. The ptrace addr points to a struct iovec pointing at memory to hold the registers along with its length. On success the length in the iovec is updated to tell userspace the actual length the kernel wrote or, if the base address is NULL, the length the kernel would have written. Because the data field is an int the arguments are backwards when compared to the Linux PTRACE_GETREGSET call.
