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:  test_tickless

Description:

This test verifies the timing accuracy of the tickless idle feature.

The test first calibrates itself by repeatedly sleeping for 10 ticks with the
tickless idle feature disabled.  It then repeats this process with the tickless
idle feature enabled.  Lastly, it compares the average measured duration of
each approach and displays the result.  The tick timing is correct if the
'diff ticks' with tickless enabled matches the SLEEP_TICKS (10) setting in
the source.

The demonstration utilizes microkernel resource APIs, timers and tickless
idle mode.

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:

Tickless Idle Test
Calibrating TSC...
Calibrated time stamp period = 0x00000000163adc3a
Do the real test with tickless enabled
Going idle for 10 ticks...
start ticks     : 343
end   ticks     : 353
diff  ticks     : 10

Cal   time stamp: 0x00000000163adc3a
variance in time stamp diff: 10 percent
