This file uses quite a different code style and changing just one line
would leads to some awkward appearance.
This is a preparation for the following replacement of
sysconf(_SC_PAGESIZE).
BTW, to depress ERROR message from checkpatch.pl, this patch replaces
strtoul with qemu_strtoul.

This is a following up patch to cleanup page size, suggested by

Patch 2 does the job, while during the cleanup I found test-mmap.c has quite a
lot code style problem. To make the code looks good, patch 1 is introduced to
make checkpatch.pl happy a little.

Use RCU_READ_LOCK_GUARD and WITH_RCU_READ_LOCK_GUARD
to replace the manual rcu_read_(un)lock calls.
I think the only change is virtio_load which was missing unlocks
in error paths; those end up being fatal errors so it's not
that important anyway.

This series of patches adds 8bit AVR cores to QEMU.
All instruction, except BREAK/DES/SPM/SPMX, are implemented. Not fully tested
yet.
However I was able to execute simple code with functions. e.g fibonacci
calculation.
This series of patches include a non real, sample board.
No fuses support

1. Avocado test
The test is based on
https://github.com/seharris/qemu-avr-tests/tree/master/free-rtos/Demo
demo which. If working correctly, prints 'ABCDEFGHIJKLMNOPQRSTUVWX' out.
it also demostrates that timer and IRQ are working
2. Boot serial test
Print out 'T' through
