Jan Kiszka d5ab9713d2 Avoid allocating TCG resources in non-TCG mode
Do not allocate TCG-only resources like the translation buffer when
running over KVM or XEN. Saves a "few" bytes in the qemu address space
and is also conceptually cleaner.

Peter Maydell 4b5dfd8246 user: Restore debug usage message for '-d ?' in user mode emulation
The code which prints the debug usage message on '-d ?' for *-user
has to come before the check for "not enough arguments", so that
"qemu-foo -d ?" prints the list of possible debug log items rather than
the generic usage message. (This was inadvertently broken in commit
c235d73.)

Matthew Fernandez c235d7387c Command line support for altering the log file location
Add command line support for logging to a location other than /tmp/qemu.log.

With logging enabled (command line option -d), the log is written to
the hard-coded path /tmp/qemu.log. This patch adds support for writing
the log to a different location by passing the -D option.

cppcheck reports this error:

commpage.c:223: error: Possible null pointer dereference:
value - otherwise it is redundant to check if value is null at line 214

The null pointer check in line 214 is indeed not needed.
If value were null, the code would crash in line 223.

Stefan Weil edcdd562ba darwin-user: Use GCC_FMT_ATTR (format checking)
The redundant forward declaration of qerror in machload.c
is removed because it should be taken from qemu.h.

Please note that this patch is untested because
I have no matching environment to compile it.

Stefan Weil e5924d8980 Replace most gcc format attributes by macro GCC_FMT_ATTR (format checking)
Since version 4.4.x, gcc supports additional format attributes.
    __attribute__ ((format (gnu_printf, 1, 2)))
should be used instead of
    __attribute__ ((format (printf, 1, 2))
because QEMU always uses standard format strings (even with mingw32).

The patch replaces format attribute printf / __printf__ by macro
GCC_FMT_ATTR which uses gnu_printf if supported.

It also removes an #ifdef __GNUC__ (not needed any longer).

Alexander Graf e3ea652962 PPC64: Fix timebase
On PPC we have a 64-bit time base. Usually (PPC32) this is accessed using
two separate 32 bit SPR accesses to SPR_TBU and SPR_TBL.

On PPC64 the SPR_TBL register acts as 64 bit though, so we get the full
64 bits as return value. If we only take the lower ones, fine. But Linux
wants to see all 64 bits or it breaks.

This patch makes PPC64 Linux work even after TB crossed the 32-bit boundary,
which usually happened a few seconds after bootup.

Anthony Liguori c227f0995e Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
