Merge remote-tracking branch 'remotes/riscv/tags/riscv-for-master-3.1-sf0' into staging

First RISC-V Patch Set for the 3.1 Soft Freeze

This pull request contains a handful of patches that have been floating
around various trees for a while but haven't made it upstream. These
patches all appear quite safe. They're all somewhat independent from
each other:

* One refactors our IRQ management function to allow multiple interrupts
to be raised an once. This patch has no functional difference.
* Cleaning up the op_helper/cpu_helper split. This patch has no
functional difference.
* Updates to various constants to keep them in sync with the latest ISA
specification and to remove some non-standard bits that snuck in.
* A fix for a memory leak in the PLIC driver.
* A fix to our device tree handling to avoid provinging a NULL string.

I've given this my standard test: building the port, booting a Fedora
root filesytem on the latest Linux tag, and then shutting down that
image. Essentially I'm just following the QEMU RISC-V wiki page's
instructions. Everything looks fine here.

We have a lot more outstanding patches so I'll definately be submitting
another PR for the soft freeze.

linux-user: Add missing TARGET_EDQUOT error code for Mips

EDQUOT is defined for Mips platform in Linux kernel in such a way
that it has different value than on most other platforms. However,
correspondent TARGET_EDQUOT for Mips is missing in Qemu code. Moreover,
TARGET_EDQUOT is missing from the table for conversion of error codes
from host to target. This patch fixes these problems.

Without this patch, syscalls add_key(), keyctl(), link(), mkdir(), mknod(),
open(), rename(), request_key(), setxattr(), symlink(), and write() will not
be able to return the right error code in some scenarios on Mips platform.
(Some of these syscalls are not yet supported in Qemu, but once they are
supported, they will need correct EDQUOT handling.)

linux-user: Use correct target SHMLBA in shmat()

The shmat() handling needs to do target-specific handling
of the attach address for shmat():
* if the SHM_RND flag is passed, the address is rounded
down to a SHMLBA boundary
* if SHM_RND is not passed, then the call is failed EINVAL
if the address is not a multiple of SHMLBA

Since SHMLBA is target-specific, we need to do this
checking and rounding in QEMU and can't leave it up to the
host syscall.

Allow targets to define TARGET_FORCE_SHMLBA and provide
a target_shmlba() function if appropriate, and update
do_shmat() to honour them.

linux-user: Clean up target_syscall.h header guards

Some of them use guard symbol TARGET_SYSCALL_H, but we also have
CRIS_SYSCALL_H, MICROBLAZE_SYSCALLS_H, TILEGX_SYSCALLS_H and
__UC32_SYSCALL_H__. They all upset scripts/clean-header-guards.pl.

Reuse of the same guard symbol TARGET_SYSCALL_H in multiple headers is
okay as long as they cannot be included together. The script can't
tell, so it warns.

The script dislikes the other guard symbols, too. They don't match
their file name (they should, to make guard collisions less likely),
and __UC32_SYSCALL_H__ is a reserved identifier.

Clean them all up: use guard symbol $target_TARGET_SYSCALL_H for
linux-user/$target/target_sycall.h.

linux-user: Renumber TARGET_QEMU_ESIGRETURN, make it not arch-specific

Currently we define a QEMU-internal errno TARGET_QEMU_ESIGRETURN
only on the MIPS and PPC targets; move this to errno_defs.h
so it is available for all architectures, and renumber it to 513.
We pick 513 because this is safe from future use as a system call return
value: Linux uses it as ERESTART_NOINTR internally and never allows that
errno to escape to userspace.
