995bf0ca57 fdc: fix drive property handling.
Fix the floppy controller init wrappers to set the drive properties
only in case the DriveInfo pointers passed in are non NULL.  This allows
to set the properties using -global.

4e17eae9f2 tcg/arm: correctly save/restore registers in prologue/epilogue
Since commit 6113d6d316 QEMU crashes
on ARM hosts. This is not a bug of this commit, but a latent bug
revealed by this commit.

The TCG code is called through a procedure call using the prologue
and epilogue code. This code does not save and restore enough registers.
The "Procedure Call Standard for the ARM Architecture" says:

  A subroutine must preserve the contents of the registers r4-r8, r10,
  r11 and SP (and r9 in PCS variants that designate r9 as v6).

The current code only saves and restores r9 to r11, and misses r4 to
r8. The patch fixes that by saving r4 to r12. Theoretically there is
no need to save and restore r12, but an even number of registers have
to be saved as per EABI.

5cd2c5b6ad Implement multi-level page tables.
Define L1_MAP_ADDR_SPACE_BITS to be either the virtual address size
(in user mode) or physical address size (in system mode), and use
that to size l1_map.  This rewrites page_find_alloc, page_flush_tb,
and walk_memory_regions.

Use TARGET_PHYS_ADDR_SPACE_BITS for the physical memory map based
off of l1_phys_map.  This rewrites page_phys_find_alloc and
phys_page_for_each.

14f24e1465 linux-user: Fix mmap_find_vma returning invalid addresses.
Don't return addresses that aren't properly aligned for the guest,
e.g. when the guest has a larger page size than the host.  Don't
return addresses that are outside the virtual address space for the
target, by paying proper attention to the h2g/g2h macros.

At the same time, place the default mapping base for 64-bit guests
(on 64-bit hosts) outside the low 4G.  Consistently interpret
mmap_next_start in the guest address space.

81d9b784df QMP: Really move the RESET event to qemu_system_reset()
Something bad has happened in the merge of commit 0ee44250, as
the log message says it's supposed to be in qemu_system_reset()
but it is do_vm_stop().

Possibly, it was a problem with the conflict resolution with
ea375f9a (which has been merged first).

This commit moves (again) the RESET event into qemu_system_reset().

b16f827bdf target-i386: fix SIB decoding with index = 4
A SIB byte with an index of 4 means "no scaled index", even if the scale
value is not 0. In 64-bit mode, if REX.X is used, an index of 4 selects
%r12. This is correctly handled by the computation of the index variable,
which includes the index bits, and also the REX.X prefix:

    index = ((code >> 3) & 7) | REX_X(s);

Thanks to Avi Kivity, Jamie Lokier and Malc for the analysis of the
problem and the initial patch.

7ffb82ca6e kbd keds: vnc
Use led status notification support in vnc.

The qemu vnc server keeps track of the capslock and numlock states based
on the key presses it receives from the vnc client.  But this fails in
case the guests idea of the capslock and numlock state changes for other
reasons.  One case is guest reboot (+ keyboard reset).  Another case are
more recent windows versions which reset capslock state before
presenting the login screen.

Usually guests use the keyboard leds to signal the capslock and numlock
state to the user, so we can use this to better keep track of capslock
and numlock state in the qemu vnc server.

Also toggle the numlock and capslock states on keydown events (instead
of keyup).  Guests do the same.
