. rename message field name macros from *PROC* to *ENDPT*,
both to reflect the new meaning and to use it to hunt down where
they are used
. _PM_SEG_FLAG in fd replaces funny segment loading construction by
PM in FS
. _MAX_MAGIC_PROC is the highest used proc number, including magic
constants such as (currently) ANY, NONE and SELF, used by the
endpoint macros to make sure they are encoded properly and no valid
endpoint number ever encodes to it.
. rename proc_nr in address copy struct to proc_nr_e (endpoint)
via cause_sig() during an exception.
moved lock check configuration to <minix/sys_config.h> instead of
kernel/config.h, because the 'relocking' field in kinfo depends on it.
other prettification: common locking macro, whether lock timing is on or
not.
other, user-includable config files. It only defines names that don't
pollute the users namespace (start with _). <minix/config.h> still works
like always; it includes sys_config.h now and defines the 'messy' names
(such as CHIP) as the 'cleaner' names (such as _MINIX_CHIP).
Changed some of the other include files to use sys_config.h and the
'cleaner' names. This solves some (past and future) compilation problems.
* Removed some variants of the SYS_GETINFO calls from the kernel;
replaced them with new PM and utils libary functionality. Fixed
bugs in utils library that used old get_kenv() variant.
* Implemented a buffer in the kernel to gather random data.
Memory driver periodically checks this for /dev/random.
A better random algorithm can now be implemented in the driver.
Removed SYS_RANDOM; the SYS_GETINFO call is used instead.
* Remove SYS_KMALLOC from the kernel. Memory allocation can now
be done at the process manager with new 'other' library functions.
This allowed removing the p_flagarlm timer from the kernel's process table.
Furthermore, I merged p_syncalrm and p_signalrm into p_alarm_timer to save
even more space. Note that processes can no longer have both a signal and
synchronous alarm timer outstanding as of now.
and type) are overwritten with newer flags/ arguments. The interface from
within the kernel is lock_notify(). User processes can make a system call with
notify(). NOTIFY fully replaces the old notification mechanism.
