Stefan Weil 6cbfb86f4c elf-loader: Fix truncation warning from coverity
Coverity reports a truncation due to cast operation on operand
reltab->sh_size from 64 bits to 32 bits for calls of load_at.

Fix the types of the function arguments to match their use in
function load_at: the offset is used for lseek which takes an
off_t parameter, the size is used for g_malloc and read.

Markus Armbruster b76d799ea5 hmp: Fix texinfo documentation
Several issues:

* Commands i and o lack @item.  Their one-liner documentation gets
  squashed into the preceding command print.  Add the obvious @item.

* Commands i, o and cpu-add lack @findex.  The function index doesn't
  have them.  Add the obvious @findex.

* Commit 727f005 put block_set_io_throttle was added in the middle of
  block_passwd.  Move it.

* Correct spelling of commands chardev-add and chardev-remove in @item
  and @findex.

* Some commands have a blank line between @item/@findex and the text,
  most don't.  Normalize to no blank line.

Markus Armbruster 46db7b862a hmp: Fix definition of command quit
The command handler is a union of two function types.  If
cmd->user_print is set, handle_user_command() calls
cmd->mhandler.cmd_new(), else cmd->mhandler.cmd().

Command definitions must therefore either set both user_print() and
mhandler.cmd_new(), or only mhandler.cmd().

quit's sets user_print and mhandler.cmd().  handle_user_command()
calls hmp_quit() through mhandler.cmd_new() rather than
mhandler.cmd(), i.e. through a function pointer with a different type.
Broken in commit 7a7f325, v1.0.

Works in practice because hmp_quit() doesn't use its arguments, and
handle_user_command() ignores its function value.

Alexey Kardashevskiy 89d5cbddee profiler: Reenable built-in profiler
2ed1ebcf6 "timer: replace time() with QEMU_CLOCK_HOST" broke compile
when configured with --enable-profiler. Turned out the profiler has been
broken for a while.

This does s/qemu_time/tcg_time/ as the profiler only works in a TCG mode.
This also fixes the compile error.

This changes profile_getclock() to return nanoseconds rather than
CPU ticks as the "profile" HMP command prints seconds and there is no
platform-independent way to get ticks-per-second rate.
Since TCG is quite slow and get_clock() returns nanoseconds (fine
enough), this should not affect precision much.

This removes unused qemu_time_start and tlb_flush_time.

Similarly, the makefile target may not match the output file name, because

Max Reitz 892f5a5270 nbd: Pass return value from nbd_handle_list()
While it does not make a difference in practice, nbd_receive_options()
generally returns -errno, so it should do that here as well; and the
easiest way to achieve this is by passing on the value returned by
nbd_handle_list().

Thomas Huth 8ffd9f4dd4 hw/usb: Include USB files only if necessary
Boards that do not include an USB controller should not provide
USB devices. However, when running "qemu-system-s390x -device help"
for example, there's still a usb-hub, usb-kbd, usb-mouse and
usb-tablet in the list of "supported" devices. Let's fix that
by compiling and linking the USB files only if it is really
necessary.

Leon Alrae a5f533909e target-mips: fix hflags modified in delay / forbidden slot
All instructions which may change hflags terminate tb. However, this doesn't
work if such an instruction is placed in delay or forbidden slot.
gen_branch() clears MIPS_HFLAG_BMASK in ctx->hflags and then generates code
to overwrite hflags with ctx->hflags, consequently we loose any execution-time
hflags modifications. For example, in the following scenario hflag related to
Status.CU1 will not be updated:
    /* Set Status.CU1 in delay slot */
    mfc0  $24, $12, 0
    lui   $25, 0x2000
    or    $25, $25, $24
    b     check_Status_CU1
    mtc0  $25, $12, 0

With this change we clear MIPS_HFLAG_BMASK in execution-time hflags if
instruction in delay or forbidden slot wants to terminate tb for some reason
(i.e. ctx->bstate != BS_NONE).

Also, die early and loudly if "unknown branch" is encountered as this should
never happen.
