Changes between 16 March 2010 - 6 April 2010
...
Mutex system call fixed for multiple contenders

Scheduler modified for real-time irq tasks

Basic codezero support for clcd device capability added.
...
1. We are not making a new clcd service container, as we dont want to keep
separate container for each device, ultimately we will have one
container managing all devices.
2. CLCD driver needs to be added.

KMI patch for devel branch on bahadir's repo.
...
Important points:
----------------
1. Works fine for pb926 + qemu.
2. Scan code logic for kryboard is not complete.
We just have generic keys and shift working.
3. Mouse scancodes are collected but not decoded.
4. Right now we are doing enable_irq(), just before we go for waiting
again for new irqs. This is not correct but we had latency issues.
This needs to be fixed immediately.
5. Also it seems like the notify_clot count should be an atomic
variable. Needs to be discussed.

Irqs are working. Scheduler modified to come back from no tasks.
...
- Userspace irq handling for timer.
- If no runnable task is left. scheduler busy loops in user context
of last runnable task until a new task becomes runnable.

Fixed few more anomalies with threaded irqs.

There is a bug that causes the sleeping irq
thread to never wake up. Investigating.

2 posix containers tested with changes. Inline assemblers fixed.

Inline assembler for irq disabling had no output variables defined.

Converted all wait/wakeup runqueue lock/unlock paths to irq versions.
...
Irqs can now touch runqueues and do async wakeups. This necessitated
that we implement all wake up wait and runqueue locking work with irqs.
All this, assumes that in an SMP setup we may have cross-cpu wake ups,
runqueue manipulation. If we later decide that we only wake up threads
in the current container, (and lock containers to cpus) we won't really
need spinlocks, or irq disabling anymore. The current set up might be
trivially less responsive, but is more flexible.

Fixed false positive mmap return value error checks.
...
Normally a pointer with its topmost bits set may cause false errors
due to the fact that such pointers result in negative integer casts.
The remedy is to use IS_ERR() macro that accepts only down to -1000
as error and any values below as valid.

Removed 2 arguments from l4_capability_control
...
l4_capability_control works well for almost all system calls
using a buffer pointer to the capability that it operates on.
Only for sharing/granting of capability lists, it is yet to be
decided how to provide a grant target id.
