Override the default stubs for getcontext(2) and swapcontext(2) so that we can flush the register stack prior to entering the kernel. This avoids having dirty registers and saves us from having to manually write them to the backing store from within the kernel. In that respect, flushing the RSE is both functionally required as well as performance optimal. On average we had 18 dirty registers when getcontext(2) was called from libthr. Since libthr does not switch back to a context created by getcontext(2), not having dealt with the dirty registers was harmless. 2003-08-02 00:49:36 +00:00			`MDASM+= Ovfork.S brk.S cerror.S exect.S fork.S getcontext.S pipe.S ptrace.S \`

Generate the normal asm stubs for all sysv system calls. Use these instead of C wrappers for the *sys indirect system calls. The indirect system calls are horribly broken on sparc64. Submitted by: tmm 2002-05-23 23:51:57 +00:00			`NOASM= break.o exit.o ftruncate.o getdomainname.o getlogin.o \`
Add the mlockall() and munlockall() system calls. - All those diffs to syscalls.master for each architecture are necessary. This needed clarification; the stub code generation for mlockall() was disabled, which would prevent applications from linking to this API (suggested by mux) - Giant has been quoshed. It is no longer held by the code, as the required locking has been pushed down within vm_map.c. - Callers must specify VM_MAP_WIRE_HOLESOK or VM_MAP_WIRE_NOHOLES to express their intention explicitly. - Inspected at the vmstat, top and vm pager sysctl stats level. Paging-in activity is occurring correctly, using a test harness. - The RES size for a process may appear to be greater than its SIZE. This is believed to be due to mappings of the same shared library page being wired twice. Further exploration is needed. - Believed to back out of allocations and locks correctly (tested with WITNESS, MUTEX_PROFILING, INVARIANTS and DIAGNOSTIC).

Clean up syscall generation in libc by removing HIDDEN_SYSCALLS and treating (almost) all system calls the same way: __sys_foo - actual syscall foo, _foo - weak definitions to __sys_foo Change PSEUDO syscalls (currently only _exit and _getlogin) to be __sys_foo (T) and _foo (W). Add $FreeBSD$ to a few files to satisfy commitprep. Suggested by: bde 2001-01-29 03:23:46 +00:00			`PSEUDO= _getlogin.o _exit.o`
