Yonattan Louise 63e3a4e772 Fix checkpatch issue - ERROR:ELSE_AFTER_BRACE 
The 'else' statement should be in the same line that the
close brace of the 'if' statement. E.g.:

	if (condition) {
		do_this();
		do_that();
	} else {
		otherwise();
	}

This commit fixed this kind of error using the following script:

	#!/bin/bash

	for file in $(find ./ -name "*.[ch]" ! -path "./scripts/*" ! -path "./host/src/wrsconfig/*");
	do
		if [ ! -h $file ];
		then
			sed -i '/^[ \t]*}$/ {
	:review_next_one_too
	N
	s/^\(.*\)\n[ \t]*else/\1 else/
	/}$/ b review_next_one_too
	}' $file;

		fi;
	done

Title:  philosopher

Description:

An implementation of a solution to the Dining Philosophers problem
(a classic multi-thread synchronization problem).  This particular
implementation demonstrates the usage of microkernel task groups,
Mutex APIs and timer drivers from multiple (6) tasks.

The philosopher always tries to get the lowest fork first (f1 then f2).
When done, he will give back the forks in the reverse order (f2 then f1).
If he gets two forks, he is EATING.  Otherwise, he is THINKING.

Each philosopher will randomly alternate between the EATING and THINKING
states.

--------------------------------------------------------------------------------

Building and Running Project:

This microkernel project outputs to the console.  It can be built and executed
on QEMU as follows:

    make pristine
    make microkernel.qemu

--------------------------------------------------------------------------------

Sample Output:

Philosopher 0 EATING
Philosopher 1 THINKING
Philosopher 2 THINKING
Philosopher 3 EATING
Philosopher 4 THINKING
Philosopher 5 THINKING








Demo Description
----------------
An implementation of a solution to the Dining Philosophers problem
(a classic multi-thread synchronization problem).  This particular
implementation demonstrates the usage of multiple (6) tasks
of differing priorities and the nanokernel semaphores and timers.
