When a modifier key is pressed or released, the USB HID keyboard still
answers NAK, unless another key is also pressed or released.

The patch fixes that by calling usb_hid_changed() when a modifier key
is pressed or released.

floatx80_is_{quiet,signaling}_nan() functions are incorrectly detecting
the type of NaN, depending on SNAN_BIT_IS_ONE, one of the two is
returning the correct value, and the other true for any kind of NaN.

This patch fixes that by applying the same kind of comparison as for
other float formats, but taking into account the explicit bit.

Break the TB after reading the count register. This makes it
possible to take timer interrupts immediately after a read of
a possibly expired timer.
Signed-off-by: NEdgar E. Iglesias <edgar.iglesias@gmail.com>

When reading cp0_count from a timer with a late trigger that should
already have expired, expire it and raise the timer irq.

This makes it possible for guest code (e.g, Linux) that first read
cp0_count, then compare it with cp0_compare and check for raised
timer interrupt lines to run reliably.

The USB keyboard emulation's translation table in hw/usb-hid.c doesn't
match the codes actually sent for the Logo (a.k.a. "Windows") or Menu
keys. This results in the guest OS not being able to receive these keys
at all when the USB keyboard emulation is being used.

In particular, both the keymap in /usr/share/kvm/keymaps/modifiers and
the evdev table in x_keymap.c map these keys to 0xdb, 0xdc, and 0xdd,
while usb_hid_usage_keys[] seems to be expecting them to be mapped to
0x7d, 0x7e, and 0x7f.

The attached patch seems to fix the problem, at least in my (limited)
testing.

With current OpenBSD, code_gen_buffer was mapped 8GB away from
text segment. Then any helpers were beyond the 2GB range of call
instruction genereated by TCG and so the calls would go nowhere,
leading to a segfault.

Fix by specifying an address for the code_gen_buffer,
hopefully free and nearby the helpers.

ORS=" " adds a blank to the name of the include file.
Some shells (e.g. dash) don't accept input redirection
(tr -d '\r' < $f) when $f ends with a blank, so they
print an error message instead of reading pci.mak.
This is a non-fatal error because pci.mak does not
contain an include line. It was introduced by commit
5d6b423c.

Using printf avoids adding a blank and is also supported
by older awk versions (this solution was suggested by
Paolo Bonzini, thank you).

The MAINTAINERS file was lacking entries concerning the TCG code, add
them based on the git history.

For the common TCG code, is probably better to keep qemu-devel@non-gnu.org
as this code can break easily, so it's better to get it reviewed by a few
persons.
