[PATCH] docs: point out that locals should be defined at the top of a block of code
by Laine Stump
Although we have nothing in make syntax-check to enforce this, and
apparently there are places where it isn't the case (according to
Dan), we should discourage the practice of defining new variables in
the middle of a block of code.

+Defining Local Variables
+------------------------
+
+Always define local variables at the top of the block in which they
+are used (before any pure code). Although modern C compilers allow
+defining a local variable in the middle of a block of code, this
+practice can lead to bugs, and must be avoided in all libvirt
+code. (As indicated in these examples, it is okay to initialize
+variables where they are defined, even if the initialization involves
+calling another function.)

[RFC PATCH 0/2] hw/sd: Deprecate the SPI mode and the SPI to SD adapter
by Philippe Mathieu-Daudé
I tried to maintain the SPI mode because it is useful in
tiny embedded devices, and thought it would be helpful for
the AVR MCUs.
As AVR was blocked, I thought it was wise to deprecate the
SPI mode as users are interested in the faster MMC mode.
Today Thomas surprised me by posting an update of it!
https://www.mail-archive.com/qemu-devel@nongnu.org/msg720089.html
I'm still posting this as RFC to discuss, but I'm reconsiderating
keeping this mode a bit more.

[PATCH] cpu_arm: fix build on non-Linux
by Roman Bogorodskiy
- Add a check for asm/hwcap.h header presence,
- Add a check for getauxval() function that is used
on Linux, and for elf_aux_info() which is a FreeBSD
equivalent.
This is based on a patch submitted by Mikael Urankar in
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=247722.
