32f3d9842d pm - sys_sigsend can fail legitimately 
. specifically, if a signal handler can't be invoked due
    to process memory, EFAULT is returned from the kernel.
    don't panic() then.

9639af49d2 RS: fix IPC privilege computation bug 
Take into account the ALL and ALL_SYS cases when constructing proper
symmetrical IPC send masks. Fix system.conf accordingly, to keep
userland processes from sending to several non-interface servers and
drivers. Also fix IS's F4 formatting.

7bef45ad3b system.conf: base ipc permissions on process names rather than labels 
From now on, the "ipc" directive in system.conf refers to process names
instead of labels, similar to the "control" directive. The old, more
fine-grained approach is deemed unnecessary and cumbersome at this time.

As side effects, this patch unbreaks late IPC permission computation as
well as the filter driver.

e2570d9b1b vm: optimisation: avl tree for virtual regions 
- regions were preivous stored in a linked list, as 'normally'
    there are just 2 or 3 (text, data, stack), but that's slow
    if lots of regions are made with mmap()

  - measurable performance improvement with gcc and clang

74c5cd7668 The profile utility can set the sprofiling mode 
- profile --nmi | --rtc sets the profiling mode

- --rtc is default, uses BIOS RTC, cannot profile kernel the presetted
  frequency values apply

- --nmi is only available in APIC mode as it uses the NMI watchdog, -f
  allows any frequency in Hz

- both modes use compatible data structures

1f89845bb2 SMP - can boot even if some cpus fail to boot 
- EBADCPU is returned is scheduler tries to run a process on a CPU
  that either does not exist or isn't booted

- this change was originally meant to deal with stupid cpuid
  instruction which provides totally useless information about
  hyper-threading and MPS which does not deal with ht at all. ACPI
  provides correct information. If ht is turned off it looks like some
  CPUs failed to boot.  Nevertheless this patch may be handy for
  testing/benchmarking in the future.

6513d20744 SMP - Process is stopped when VM modifies the page tables 
- RTS_VMINHIBIT flag is used to stop process while VM is fiddling with
  its pagetables

- more generic way of sending synchronous scheduling events among cpus

- do the x-cpu smp sched calls only if the target process is runnable.
  If it is not, it cannot be running and it cannot become runnable
  this CPU holds the BKL

06b6e5624a SMP - Changed prototype of sys_schedule() 
- sys_schedule can change only selected values, -1 means that the
  current value should be kept unchanged. For instance we mostly want
  to change the scheduling quantum and priority but we want to keep
  the process at the current cpu

- RS can hand off its processes to scheduler

- service can read the destination cpu from system.conf

- RS can pass the information farther

Tomas Hruby
1e273f640e SMP - Scheduler can assign process to a cpu 
- machine information contains the number of cpus and the bsp id

- a dummy SMP scheduler which keeps all system processes on BSP and
  all other process on APs. The scheduler remembers how many processes
  are assigned to each CPU and always picks the one with the least
  processes for a new process.

copy file descriptors from one process to another.

19b790eb53 vfs: don't use a mountpoint if it's in use for anything else. 
(this avoids data structure confusion if a mountpoint is reused as
a mountpoint until that's properly fixed.)

6bbcab3ec4 Clean up MFS a bit: 
- Remove unused includes.
 - Add include guards to headers.
 - Use unsigned variables in case they're never going to hold a negative
   value. This causes GCC's complaints to disappear and should make flexelint
   a lot happier, too.
 - Make functions private when they're used only within a module.
 - Remove unused variables.
 - Add casts where appropriate.
