For simplicity address the problem by adding PCI_IOBASE to the physical
address requested in the respective wrapper macros only, observing that
the raw accessors such as `__insb', `__outsb', etc. are not supposed to
be used other than by said macros.  Remove the cast to `long' that is no
longer needed on `addr' now that it is used as an offset from PCI_IOBASE
and add parentheses around `addr' needed for predictable evaluation in
macro expansion.  No need to make said adjustments in separate changes
given that current code is gravely broken and does not ever work.

I'm merging this in as a single commit as it's a dependency for some
other work.

* commit '3baca1a4':
  RISC-V: Add mvendorid, marchid, and mimpid to /proc/cpuinfo output

Commit 2139619b ("riscv: mmap with PROT_WRITE but no PROT_READ is
invalid") made mmap() reject mappings with only PROT_WRITE set in an
attempt to fix an observed inconsistency in behavior when attempting
to read from a PROT_WRITE-only mapping. The root cause of this behavior
was actually that while RISC-V's protection_map maps VM_WRITE to
readable PTE permissions (since write-only PTEs are considered reserved
by the privileged spec), the page fault handler considered loads from
VM_WRITE-only VMAs illegal accesses. Fix the underlying cause by
handling faults in VM_WRITE-only VMAs (patch 1) and then re-enable
use of mmap(PROT_WRITE) (patch 2), making RISC-V's behavior consistent
with all other architectures that don't support write-only PTEs.

This is because the mm->context.vdso_info is NULL in vfork case. From
another side, mm->context.vdso_info either points to vdso info
for RV64 or vdso info for compat, there's no need to bloat riscv's
mm_context_t, we can handle the difference when setup the additional
page for vdso.

Since composable cache may be L3 cache if private L2 cache exists, we
should use its original name "composable cache" to prevent confusion.

This patchset contains the modification which is related to ccache, such
as DT binding and EDAC driver.

* b4-shazam-merge:
  riscv: Add cache information in AUX vector
  soc: sifive: ccache: define the macro for the register shifts
  soc: sifive: ccache: use pr_fmt() to remove CCACHE: prefixes
  soc: sifive: ccache: reduce printing on init
  soc: sifive: ccache: determine the cache level from dts
  soc: sifive: ccache: Rename SiFive L2 cache to Composable cache.

There are no standard CSR registers to provide cache information, the
way for RISC-V is to get this information from DT. sysconf syscall
could use them to get information of cache through AUX vector.

syzbot found that kcm_tx_work() could crash [1] in:

	/* Primarily for SOCK_SEQPACKET sockets */
	if (likely(sk->sk_socket) &&
	    test_bit(SOCK_NOSPACE, &sk->sk_socket->flags)) {
<<*>>	clear_bit(SOCK_NOSPACE, &sk->sk_socket->flags);
		sk->sk_write_space(sk);

I think the reason is that another thread might concurrently
run in kcm_release() and call sock_orphan(sk) while sk is not
locked. kcm_tx_work() find sk->sk_socket being NULL.

Eric Dumazet reported a use-after-free related to the per-netns ehash
series. [0]

When we create a TCP socket from userspace, the socket always holds a
refcnt of the netns.  This guarantees that a reqsk timer is always fired
before netns dismantle.  Each reqsk has a refcnt of its listener, so the
listener is not freed before the reqsk, and the net is not freed before
the listener as well.

OTOH, when in-kernel users create a TCP socket, it might not hold a refcnt
of its netns.  Thus, a reqsk timer can be fired after the netns dismantle
and access freed per-netns ehash.

To avoid the use-after-free, we need to clean up TCP_NEW_SYN_RECV sockets
in inet_twsk_purge() if the netns uses a per-netns ehash.
