when loading large binaries such as netsurf, with many
symbols, our hash table fills up with collisions and
loading the symbol table gets very slow. Bumping it up
drops the time to lstk() in acid on netsurf from 4 minutes
to 8 seconds.
Call exits(0) instead of returning from main. Also call sysfatal if
writing of image data fails. Previously, qr(1) would exit with
default non-nil status "main" unconditionally as a result of returning
from main.
/$objtype/include/ape/math.h contained an almost
identical copy of math.h for each architecture.
The only difference between them architectures
was that some had an incorrect version of isinf
defined.
This change picks one of the versions of math.h
with a correct definition, moves it to /sys/include,
and removes the redundant versions.
Tilting allows using left/right rotated or invetrted display orientation.
This can be changed at runtime such as: echo tilt right > /dev/vgactl
This removes the old panning and vga overlays as they are only implemented
with some ancient vga controllers.
The idea is to avoid the magic files that contain
per process information in devcons when possible.
It will make it easier to deprecate them in the future.
Previously, mmurelease() was always called with
palloc spinlock held.
This is unneccesary for some mmurelease()
implementations as they wont release pages
to the palloc pool.
This change removes pagechainhead() and
pagechaindone() and replaces them with just
freepages() call, which aquires the palloc
lock internally as needed.
freepages() avoids holding the palloc lock
while walking the linked list of pages,
avoding some lock contention.

we might as well handle the per process cycle
counter in the portable part instead of duplicating the code
in every arch and have inconsistent implementations.
we now have a portable kenter() and kexit() function,
that is ment to be used in trap/syscall from user,
which updates the counters.
some kernels missed initializing Mach.cyclefreq.
Provide a central function to change the user id
of the calling process.
This is mostly used by programs to become the none
user, followed by a call to newns().
