Tracking cpuid features is easier when sync'ed with kernel
source code. Note though that while in kernel feature bits
are not part of ABI, we're saving bits into an image so
as result make sure they are posted in proper place together
with keeping in mind the backward compatibility issue.
Here we also start using v2 of cpuinfo image with more
feature bits.

As it's aligned to 16, all structures that contain it should be
also aligned to 16. In the kernel there is no such align as
there two separate definitions of i387_fxsave_struct:
one for ia32 and another for x86_64.
Fixes newly introduced align warning in gcc-8.1:
In file included from compel/include/uapi/compel/asm/sigframe.h:7,
from compel/plugins/std/infect.c:13:

} __packed;
^
It doesn't change the current align of the struct, as containing
structures are __packed and it aligned already *by fact*.
It only affects the function users of the struct's local variables:
now they lay aligned on a stack.

On Skylake processors and kernel older than v4.14
ptrace(PTRACE_GETREGSET, pid, NT_X86_XSTATE, iov)
may return not full xstate, ommiting FP part (that is XFEATURE_MASK_FP).
There is a patch which describes this bug:
https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1318800.html
Anyway, it's fixed in v4.14 kernel by (what we believe with Andrey) this:
https://patchwork.kernel.org/patch/9567939/
As we still support kernels from v3.10 and newer, we need to have a
workaround for this kernel bug on Skylake CPUs.

Amazon VM to test this. I wish more bug reporters were like you.

get_task_regs() needs to know if it needs to use workaround
for a Skylake ptrace() bug. The next patch will introduce a
new flag for that.
I also thought about making 3 versions of get_task_regs() and
adding them to ictx->get_task_regs() depending on the flags..
But get_task_regs() is a private function and infect_ctx is
a uapi.. So, let's just pass context flags to get_task_regs().

For dumping threads we execute parasite code before we collect the
floating point registers with get_task_regs().
The following describes the code path were this is done:
dump_task_threads()
for (i = 0; i < item->nr_threads; i++)
dump_task_thread()
parasite_dump_thread_seized()
compel_prepare_thread()
prepare_thread()
### Get general purpose registers ###
ptrace_get_regs(ctx->regs)
### parasite code is executed in thread ###
compel_run_in_thread(tctl, PARASITE_CMD_DUMP_THREAD)
compel_get_thread_regs()
### Get FP and VX registers ###
get_task_regs()
Since on s390 gcc uses floating point registers to cache general
purpose without the -msoft-float option the floating point
registers would have been clobbered after compel_run_in_thread().
With this patch we first save all thread registers with task_get_regs() and
then call the parasite code.
We introduce a new function arch_set_thread_regs() that restores the saved
registers for all threads. This is necessary for criu dump --leave-running,
--check-only, and error handling.
Pre-dump does not require to save the registers for the threads because
because only the main thread (task) is used for parsite code execution.
The above changes allow us to use all register sets in the parasite
code - therefore we can remove -msoft-float on s390.

The objective is to only do parasite code linking once -- when we link
parasite objects with compel plugin(s). So, let's use ar (rather than
ld) here. This way we'll have a single ld invocation with the proper
flags (from compel ldflags) etc.
There are two tricks in doing it:
1. The order of objects while linking is important. Therefore, compel
plugins should be the last to add to ld command line.
2. Somehow ld doesn't want to include parasite-head.o in the output
(probably because no one else references it), so we have to force
it in with the modification to our linker scripts.
NB: compel makefiles are still a big mess, but I'll get there.
