target-ppc: Add hooks for handling tcg and kvm limitations
On target-ppc, our table of CPU types and features encodes the features as
found on the hardware, regardless of whether these features are actually
usable under TCG or KVM. We already have cases where the information from
the cpu table must be fixed up to account for limitations in the emulation
method we're using. e.g. TCG does not support the DFP and VSX instructions
and KVM needs different numbering of the CPUs in order to tell it the
correct thread to core mappings.
This patch cleans up these hacks to handle emulation limitations by
consolidating them into a pair of functions specifically for the purpose.

pseries: Consolidate hack for RTAS display-character usage
Currently the pseries machine contains not one but two somewhat ugly hacks
to allow printing of early debug messages before the guest has properly
read the device tree.
First, we special case H_PUT_TERM_CHAR so that a vtermno of 0 (usually
invalid) will look for a suitable vty and use that. This supports Linux's
early debug code which will use H_PUT_TERM_CHAR with vtermno==0 before
reading the device tree. Second, we support the RTAS display-character call.
This takes no vtermno so we assume the address of the default first VTY.
This patch makes things more consistent by folding the second hack into the
first. Now, display-character uses the existing vty_lookup() function to
do the same search for a suitable VTY.

PPC: Fix TLB invalidation bug within the PPC interrupt handler.
Commit
41557447d30eeb944e42069513df13585f5e6c7f also introduced a subtle TLB
flush bug. By applying a mask to the interrupt MSR which cleared the IR/DR
bits at the start of the interrupt handler, the logic towards the end of the
handler to force a TLB flush if either one of these bits were set would never
be triggered.
This patch simply changes the IR/DR bit check in the TLB flush logic to use
the original MSR value (albeit with some interrupt-specific bits cleared) so
that the IR/DR bits are preserved at the point where the check takes place.

kvm: add flightrecorder script
The kvm kernel module includes a number of trace events which can be
useful when debugging system behavior. Even on production systems these
trace events can be used to observe guest behavior and identify the
source of problems.
The kvm_flightrecorder script is a command-line wrapper for the
/sys/kernel/debug/tracing interface. Kernel symbols do not need to be
installed.
This script captures a fixed-size buffer of KVM trace events. Recent
events overwrite the oldest events when the buffer size is exceeded and
it is possible to leave KVM tracing enabled for any period of time with
just a fixed-size buffer. If the buffer is large enough this script is
a useful tool for collecting detailed information after an issue occurs
with a guest. Hence the name "flight recorder".
The script can also be used in 'tail' mode to simply view KVM trace
events as they occur. This is handy for development and to ensure that
the guest is indeed running.

qdev: qdev_unplug(): use error_set()
It currently uses qerror_report(), but next commit will convert
the drive_del command to the QAPI and this requires using
error_set().
One particularity of qerror_report() is that it knows when it's
running on monitor context or command-line context and prints the
error message accordingly. error_set() doesn't do this, so we
have to be careful not to drop error messages.
qdev_unplug() has three kinds of usages:
1. It's called when hot adding a device fails, to undo anything
that has been done before hitting the error
2. It's called by function monitor functions like device_del(),
to unplug a device
3. It's used by xen_platform.c in a way that doesn't _seem_ to
be in monitor context
Only item 2 can print an error message to the user, this commit
maintains that.

w64: Fix data type of tb_next and other variables used for host addresses
QEMU host addresses must use uintptr_t to be portable for hosts with
an unusual size of long (w64).
tb_jmp_offset is an uint16_t value, therefore the local variable offset
in function tb_set_jmp_target was changed from unsigned long to uint16_t.
The type cast to long in function tb_add_jump now also uses uintptr_t.
For the bit operation used here, the signedness of the type cast does
not matter.
Some remaining unsigned long values are either only used for ARM assembler
code or will be fixed in a later patch for PPC.
v2:
Fix signature of tb_find_pc in exec.c, too (hint from Blue Swirl, thanks).
There remain lots of other long / unsigned long in exec.c which must be

a change in socket state that requires a select call.
Since the interrupt fires only once per recv call, or only once
after a send call returns EWOULDBLOCK we can activate it on all events
unconditionally. If QEMU is momentarily uninterested on some condition,
the main loop will not busy wait. Instead, it may get one extra wakeup,
but then it will ignore the condition until progress occurs and/or
qemu_set_fd_handler is called to set a callback. At this point the

Userspace ARM BE8 support
Add support for ARM BE8 userspace binaries.
i.e. big-endian data and little-endian code.
In principle LE8 mode is also possible, but AFAIK has never actually
been implemented/used.
System emulation doesn't have any useable big-endian board models,
but should in principle work once you fix that.
Dynamic endianness switching requires messing with data accesses,
preferably with TCG cooperation, and is orthogonal to BE8 support.

[PMM: various changes, mostly as per my suggestions in code review:
* rebase
* use EF_ defines rather than hardcoded constants
* make bswap_code a bool for future VMSTATE macro compatibility
* update comment in cpu.h about TB flags bit field usage
* factor out load-code-and-swap into arm_ld*_code functions and
get_user_code* macros
* fix stray trailing space at end of line
* added braces in disas.c to satisfy checkpatch

elf.h: Update EF_ARM_ constants to newer ABI versions
Update the EF_ARM_* constants (for the ELF header e_flags field)
to include the newer flags specified for later versions of the ABI.
(This set of constants is from include/elf/arm.h from binutils-2.17
and so licensed under GPL-v2-or-later.)

arm-linux-user: fix elfload.c's AT_HWCAP to reflect cpu features.
The cpu capabilities passed by the elf loader in AT_HWCAP where
a constant.
Make AT_HWCAP reflect the emulated cpu features in order to give
correct clues to eglibc.

linux-user/arm/syscall_nr.h: Add syscall number for ppoll
The list of ARM syscall numbers was missing the entry for ppoll,
which meant we were accidentally not providing it. (This wasn't
causing any practical issues beyond warnings about unimplemented
syscalls, because glibc will fall back to another code path if the
syscall isn't present.)
