For level sensitive interrupts, ISR bits are cleared when the input pin
is lowered. This is incorrect. Only software can clear ISR bits (via
IAR or direct write to ISR with !MER(2)).

The UART IRQ is edge sensitive, whereas the machine was registering it
as level sensitive. Fix.

rotr_i32 calculates the amount to left shift and puts it into a

add2_i64 was adding the lower double word to the upper double word

If our input and output is in the same register, bswap64 tries to
undo a rotate of the input. This just ends up rotating the output.

The rldcl instruction doesn't have an sh field, so the minor opcode
is shifted 1 bit. We were using the XO30 macro which shifted the
minor opcode 2 bits.
Remove XO30 and add MD30 and MDS30 macros which match the
Power ISA categories.

Initial commit for emulated Non-Volatile-Memory Express (NVMe) pci
storage device.
NVMe is an open, industry driven storage specification defining
an optimized register and command set designed to deliver the full
capabilities of non-volatile memory on PCIe SSDs. Further information
may be found on the organizations website at:
http://www.nvmexpress.org/
This commit implements the minimum from the specification to work with
existing drivers.

Just call sd_create_branch() in the snapshot_goto to rollback the image is good
enough. With this patch, 'loadvm' process for sheepdog is modified:
Suppose we have a snapshot chain A --> B --> C, we do 'loadvm A' so as to get
a new chain,
A --> B
|
V
C1
in the old code:
1 reload inode of A (in snapshot_goto)
2 read vmstate via A's vdi_id (loadvm_state)
3 delete C and create C1, reload inode of C1 (sd_create_branch on write)
with this patch applied:
1 reload inode of A, delete C and create C1 (in snapshot_goto)
2 read vmstate via C1's parent, that is A's vdi_id (loadvm_state)
This will fix the possible bug that QEMU exit between 2 and 3 in the old code

The call to drv->bdrv_reopen_prepare() can fail due to reasons
other than an open failure. Unfortunately, we can't use errno
nor -ret, cause they are not always set.

Commit 047d4e151dd46 "Unbreak -no-quit for GTK, validate SDL options" broke
build of qemu without sdl, by referencing `no_frame' variable which is defined
inside #if SDL block. Fix that by defining that variable unconditionally.
This is a better fix for the build issue introduced by that patch than
a revert. This change keeps the new functinality introduced by that patch
and just fixes the compilation. It still is not a complete fix around the
original issue (not working -no-frame et al with -display gtk), because it
makes only the legacy interface working, not the new suboption interface,
so a few more changes are needed.

bd07684aacfb61668ae2c25b7dd00b64f3d7c7f3 added a test to ensure BSY
flag is set when a flush request is in flight. It does this by setting
a blkdebug breakpoint on flush_to_os before issuing a CMD_FLUSH_CACHE.
It then resumes CMD_FLUSH_CACHE operation and checks that BSY is unset.
The actual unsetting of BSY does not occur until ide_flush_cb gets
called in a bh, however, so in some cases this check will race with
the actual completion.
Fix this by polling the ide status register until BSY flag gets unset
before we do our final sanity checks. According to
f68ec8379e88502b4841a110c070e9b118d3151c this is in line with how a guest
would determine whether or not the device is still busy.

Currently QEMU provides a local clone of the file libfdt_env.h in
/include. This file is supposed to come with the libfdt package and is
only needed for broken installs of libfdt. Now that we have submodule
dtc, just ignore these broken installs and prompt for the dtc submodule
install instead. QEMU's local libfdt_env.h is removed accordingly.
Manifests as a bug when building QEMU with modern libfdt. The new
version of libfdt does not compile when QEMUs libfdt_env.h takes
precedence over the hosts.
