Stefan Weil 541dc0d47f Use new macro QEMU_PACKED for packed structures
Most changes were made using these commands:

git grep -la '__attribute__((packed))'|xargs perl -pi -e 's/__attribute__\(\(packed\)\)/QEMU_PACKED/'
git grep -la '__attribute__ ((packed))'|xargs perl -pi -e 's/__attribute__ \(\(packed\)\)/QEMU_PACKED/'
git grep -la '__attribute__((__packed__))'|xargs perl -pi -e 's/__attribute__\(\(__packed__\)\)/QEMU_PACKED/'
git grep -la '__attribute__ ((__packed__))'|xargs perl -pi -e 's/__attribute__ \(\(__packed__\)\)/QEMU_PACKED/'
git grep -la '__attribute((packed))'|xargs perl -pi -e 's/__attribute\(\(packed\)\)/QEMU_PACKED/'

Whitespace in linux-user/syscall_defs.h was fixed manually
to avoid warnings from scripts/checkpatch.pl.

Manual changes were also applied to hw/pc.c.

I did not fix indentation with tabs in block/vvfat.c.
The patch will show 4 errors with scripts/checkpatch.pl.

Blue Swirl 97b348e7d2 Remove unused is_softmmu parameter from cpu_handle_mmu_fault
Parameter is_softmmu (and its evil mutant twin brother is_softmuu)
is not used in cpu_*_handle_mmu_fault() functions, remove them
and adjust callers.

Blue Swirl f081c76ccf Move cpu_has_work and cpu_pc_from_tb to cpu.h
Move functions cpu_has_work() and cpu_pc_from_tb() from exec.h to cpu.h. This is
needed by later patches.

Jan Kiszka e205c7902f Switch build system to accompanied kernel headers
This helps reducing our build-time checks for feature support in the
available Linux kernel headers. And it helps users that do not have
sufficiently recent headers installed on their build machine.

Consequently, the patch removes and build-time checks for kvm and vhost
in configure, the --kerneldir switch, and KVM_CFLAGS. Kernel headers are
supposed to be provided by QEMU only.

s390 needs some extra love as it carries redefinitions from kernel
headers.

Remove the now unused cc field that was only required to not break
bisectability.

Alexander Graf 4e8367812a s390x: Shift variables in CPUState for memset(0)
The default reset handler does a memset(0) until right in between CPU_COMMON.
I incorrectly changed that behavior on the s390x port, so let's move the fields
in CPUState around to reflect the correct split up to which point memset(0)
zeros out everything.

Alexander Graf d1ff903ca5 s390x: keep hint on virtio managing size
The s390x virtio bus keeps management information on virtio after the top
of the guest's RAM. We need to be able to tell the guest the size of its
RAM (without virtio stuff), but also be able to trap when the guest accesses
RAM outside of its scope (including virtio stuff).

So we need a variable telling us the size of the virtio stuff, so we can
calculate the highest available RAM address from that.

While at it, also increase the maximum number of virtio pages, so we play
along well with more recent kernels that spawn a ridiculous number of virtio
console adapters.

Alexander Graf 1f20626679 s390x: make kvm exported functions conditional on kvm
We have some helper functions we use to directly invoke KVM
functionality from device emulation code.

This patch replaces those exported functions with static inline
stubs when not building with KVM enabled.

Alexander Graf bcec36eaa0 s390x: Prepare cpu.h for emulation
We need to add some more logic to the CPU description to leverage emulation
of an s390x CPU. This patch adds all the required helpers, fields in CPUState
and constant definitions required for user and system emulation.

Removes a set of ifdefs from exec.c.

Introduce TARGET_VIRT_ADDR_SPACE_BITS for all targets other
than Alpha.  This will be used for page_find_alloc, which is
supposed to be using virtual addresses in the first place.

Alexander Graf 10ec51174c S/390 CPU fake emulation
Because Qemu currently requires a TCG target to exist and there are quite some
useful helpers here to lay the groundwork for out KVM target, let's create a
stub TCG emulation target for S390X CPUs.

This is required to make tcg happy. The emulation target itself won't work
though.
