Reduce atomicity while emitting opcodes, instead of later
during code generation.  This ensures that any helper called

b5e0d5d22f target/i386: Fix 32-bit wrapping of pc/eip computation 
In 32-bit mode, pc = eip + cs_base is also 32-bit, and must wrap.
Failure to do so results in incorrect memory exceptions to the guest.
Before 732d548732, this was implicitly done via truncation to
target_ulong but only in qemu-system-i386, not qemu-system-x86_64.

To fix this, we must add conditional zero-extensions.
Since we have to test for 32 vs 64-bit anyway, note that cs_base
is always zero in 64-bit mode.

06ecb6ac19 docs: clean-up the xenpvh documentation 
I noticed the code blocks where not rendering properly so thought I'd
better fix things up. So:

  - Use better title for the machine type
  - Explain why Xen is a little different
  - Add a proper anchor to the tpm-device link
  - add newline so code block properly renders
  - add some indentation to make continuation clearer

755ae3811f block: Fix AioContext locking in qmp_block_resize() 
The AioContext must be unlocked before calling blk_co_unref(), because
it takes the AioContext lock internally in blk_unref_bh(), which is
scheduled in the main thread. If we don't unlock, the AioContext is
locked twice and nested event loops such as in bdrv_graph_wrlock() will
deadlock.

16b6273b4b meson, xen: fix condition for enabling the Xen accelerator 
A misspelled condition in xen_native.h is hiding a bug in the enablement of
Xen for qemu-system-aarch64.  The bug becomes apparent when building for
Xen 4.18.

While the i386 emulator provides the xenpv machine type for multiple architectures,
and therefore can be compiled with Xen enabled even when the host is Arm, the
opposite is not true: qemu-system-aarch64 can only be compiled with Xen support
enabled when the host is Arm.

Expand the computation of accelerator_targets['CONFIG_XEN'] similar to what is
already there for KVM.

5746f70d68 i386/sev: Avoid SEV-ES crash due to missing MSR_EFER_LMA bit 
Commit 7191f24c7f ("accel/kvm/kvm-all: Handle register access errors")
added error checking for KVM_SET_SREGS/KVM_SET_SREGS2. In doing so, it
exposed a long-running bug in current KVM support for SEV-ES where the
kernel assumes that MSR_EFER_LMA will be set explicitly by the guest
kernel, in which case EFER write traps would result in KVM eventually
seeing MSR_EFER_LMA get set and recording it in such a way that it would
be subsequently visible when accessing it via KVM_GET_SREGS/etc.

However, guest kernels currently rely on MSR_EFER_LMA getting set
automatically when MSR_EFER_LME is set and paging is enabled via
CR0_PG_MASK. As a result, the EFER write traps don't actually expose the
MSR_EFER_LMA bit, even though it is set internally, and when QEMU
subsequently tries to pass this EFER value back to KVM via
KVM_SET_SREGS* it will fail various sanity checks and return -EINVAL,
which is now considered fatal due to the aforementioned QEMU commit.

This can be addressed by inferring the MSR_EFER_LMA bit being set when
paging is enabled and MSR_EFER_LME is set, and synthesizing it to ensure
the expected bits are all present in subsequent handling on the host
side.

Ultimately, this handling will be implemented in the host kernel, but to
avoid breaking QEMU's SEV-ES support when using older host kernels, the
same handling can be done in QEMU just after fetching the register
values via KVM_GET_SREGS*. Implement that here.

80a37b039e hw/ufs: avoid generating the same ID string for different LU devices 
QEMU would not start when trying to create two UFS host controllers and
a UFS logical unit for each with the following options:

-device ufs,id=bus0 \
-device ufs-lu,drive=drive1,bus=bus0,lun=0 \
-device ufs,id=bus1 \
-device ufs-lu,drive=drive2,bus=bus1,lun=0 \

This is because the same ID string ("0:0:0/scsi-disk") is generated
for both UFS logical units.

To fix this issue, prepend the parent pci device's path to make
the ID string unique.
("0000:00:03.0/0:0:0/scsi-disk" and "0000:00:04.0/0:0:0/scsi-disk")
