kamil 3e48d45743 Revert asctime() namespacing 
asctime() is optionally a cancellation point in the POSIX spec.
It's not true for NetBSD.

kamil b4e223d109 Revert namespacing of atoi(3) 
Sanitizers can handle recursive interceptions in some / most cases, if they
will cause damage the problem will be not workaroundable without libc
changes - I will be back to it.

Keep namespace of asctime() as this can be a cancellation point according
to POSIX. Right now it's not implemented on NetBSD. Defer it for later.

Keep weak symbols and namespace for wait6(2) as this could be a
cancellation point as well. Defer this for later.

Sanitizers's [recursive] interceptors are a hack and moving one way or
another can cause new sets of problems. Recursive ones can be useful and
cause problems (on Linux there are known with with signal handlers).

maxv 99d8611c28 Implement a real hotpatch feature. 
Define a HOTPATCH() macro, that puts a label and additional information
in the new .rodata.hotpatch kernel section. In patch.c, scan the section
and patch what needs to be. Now it is possible to hotpatch the content of
a macro.

SMAP is switched to use this new system; this saves a call+ret in each
kernel entry/exit point.

Many other operating systems do the same.

kamil f615c5a6fd doc: Tweak the vadvise removal entry in CHANGES 
Note the removal of the vadvise header
 2018-01-06 16:52:57 +00:00
kamil f98f70a745 Revert vadvise(2) removal 
This system call was used in legacy Lisp code, that was inherited to modern
age and still compiled against supported compat layers (e.g. in clisp,
oaklisp, Franz Lisp).

It used to instruct the kernel about paging policy (G/C aware, flush etc).

Newly compiled code (assuming that it will detect vadvise()) will use the
libc stub for vadvise(). The headers for this interface are gone.

vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix,
sunos or aout68k ABI, don't bother with this.
