d615efac7c target-arm: Correct handling of UXN bit in ARMv8 LPAE page tables
In v8 page tables bit 54 in the PTE is UXN in the EL0/EL1 translation regimes
and XN elsewhere. In v7 the bit is always XN. Since we only emulate EL0/EL1 we
can just treat this bit as UXN whenever we are in v8 mode.

Also correctly extract the upper attributes from the PTE entry, the v8 version
tried to avoid extracting the CONTIG bit and ended up with the upper bits being
off-by-one. Instead behave the same as v7 and extract (but ignore) the CONTIG
bit.

This fixes "Bad mode in Synchronous Abort handler detected, code 0x8400000f"
seen when modprobing modules under Linux.

8d5c773e32 target-arm: Prepare cpreg writefns/readfns for EL3/SecExt
This patch changes some readfns/writefns to use raw_write
and raw_read functions, which use the fieldoffset specified
in ARMCPRegInfo instead of directly accessing the field.
This will simplify patches for EL3 & Security Extensions.

cpu64.c contains a reginfo list for the impdef registers on
the Cortex-A57; however we forgot to actually call define_arm_cp_regs(),
so it was sitting there doing nothing. Remedy this omission.

61e9924149 vexpress: Add support for the -bios flag to provide firmware
Right now to run firmware inside the QEMU VExpress model requires
padding out the firmware image to the size of the virtual flash and
passing it in via the -pflash argument. If the firmware image is passed
without padding, then QEMU will fail. Also, when passed as a -pflash
argument, QEMU treats the file as persistent storage and will modify the
file.

The -bios flag provides the semantics that we want for providing a
firmware image. This patch maps the contents of the -bios file into the
address space at the boot flash location.

Tested with the vexpress-a15 model and the Tianocore port.

5b808275f3 trace: Multi-backend tracing
Adds support to compile QEMU with multiple tracing backends at the same time.

For example, you can compile QEMU with:

  $ ./configure --enable-trace-backends=ftrace,dtrace

Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system.

This patch allows having both available without recompiling QEMU.

80ff35cd3f simpletrace: add support for trace record pid field
Extract the pid field from the trace record and print it.

Change the trace record tuple from:
  (event_num, timestamp, arg1, ..., arg6)
to:
  (event_num, timestamp, pid, arg1, ..., arg6)

Trace event methods now support 3 prototypes:
1. <event-name>(arg1, arg2, arg3)
2. <event-name>(timestamp, arg1, arg2, arg3)
3. <event-name>(timestamp, pid, arg1, arg2, arg3)

Existing script continue to work without changes, they only know about
prototypes 1 and 2.

26896cbf35 trace: add pid field to simpletrace record
It is useful to know the QEMU process ID when working with traces from
multiple VMs.  Although the trace filename may contain the pid, tools
that aggregate traces or even trace globally need somewhere to record
the pid.

There is a reserved field in the trace event header struct that we can
use.

It is not necessary to bump the simpletrace file format version number
because it has already been incremented for the QEMU 2.1 release cycle
in commit "trace: [simple] Bump up log version number".

7efea76377 e1000: remove broken support for 82573L
Currently, e1000 support is based on the manual for the 8254xx
model series. 82573x models are documented in a separate manual
(see http://www.intel.com/content/dam/www/public/us/en/documents/manuals/pcie-gbe-controllers-open-source-manual.pdf)
and the 82573L device ID no longer works correctly on either Linux
(3.14.*) or Windows 7.

This patch removes stale code claiming to support 82573L, cleaning
up the code base for the remaining 8254xx model series.

37654d9e6a target-cris/translate.c: Remove _t_gen_mov_TN_env and _t_gen_mov_env_TN
The wrapper functions _t_gen_mov_TN_env and _t_gen_mov_env_TN are only
used via their accompanying non-underscore macros. The check they add
on offset is thus pointless, since the compiler will complain if the
struct field passed to the macro is not part of the struct. Remove the
functions and make the macros directly expand to the appropriate
tcg_gen_{ld,st}_tl calls.

This conveniently avoids a warning due to _t_gen_mov_TN_env() being
unused.

b544c1aba8 sheepdog: fix vdi object update after live snapshot
sheepdog driver should decide a write request is COW or not based on inode
object which is active when the write request is issued.

Example of wrong inode update path in the previous driver:
1. drier issues an ordinal write request to an existing object
2. user creates a snapshot of the VDI before the write request is completed
3. the respones for the request is RDONLY, because the VDI is already a snapshot
4. the driver reload an inode object of the new active VDI, then issues a write
   request again
5. the second write request can be completed
6. driver decide the request is COW or not with the below conditional branch:
   	  if (s->inode.data_vdi_id[idx] != s->inode.vdi_id) {
7. the ID of the written object and VID of the new active VDI is different, so
   the driver updates data_vdi_id[idx] and writes inode object
8. the existing object cannot be seen by the new active VDI, it results object
   leaking

f38b161203 apb: handle reading/writing of IOMMU control registers
While the registers are documented as being 64-bit, Linux seems to access
them in two halves as 2 x 32-bit accesses. Make sure that we can correctly
handle this case.

366d4f7e00 cg3: add extra check to prevent CG3 register array overflow
The case statements in the CG3 read and write register routines have a maximum
value of CG3_REG_SIZE, so if a value were written to this offset then it
would overflow the register array.

Currently this cannot be exploited since the MemoryRegion restricts accesses
to the range 0 ... CG3_REG_SIZE - 1, but it seems worth clarifying this for
future review and/or static analysis.

This can help a user understand why -global was ignored.

For example: with "-vga cirrus"; "-global vga.vgamem_mb=16" is just
ignored when "-global cirrus-vga.vgamem_mb=16" is not.

This is currently clear when the wrong property is provided:
