2014-05-13savevm: Remove all the unneeded version_minimum_id_old (arm)Juan Quintela
After commit 767adce2d, they are redundant. This way we don't assign them except when needed. Once there, there were lots of cases where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (apart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

2014-02-08util/fifo8: clear fifo head upon resetBeniamino Galvani
To improve the predictability of fifo8_pop_buf(), the fifo head is set to the start of data buffer upon a reset so that the first call to the function will be able to retrieve all data in the fifo.

2014-02-08util/fifo8: implement push/pop of multiple bytesBeniamino Galvani
The patch adds functions fifo8_push_all() and fifo8_pop_buf() which can be used respectively to push the content of a memory buffer to the fifo and to pop multiple bytes obtaining a pointer to the fifo backing buffer. In addition, it implements fifo8_num_free() and fifo8_num_used() which allow to check if a multi-byte operation can be performed.

2013-03-01hw: move fifo.[ch] to libqemuutilPaolo Bonzini
fifo.c is generic code that can be easily unit tested. So it belongs in libqemuutil. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
