     but missed to clear that bit when loading the TLB.

   - Graphics card memory size was not correctly aligned

Commit df24e178 ("parisc: Add vDSO support") introduced the vDSO
support, for which a _PAGE_SPECIAL page table flag was needed.  Since we
wanted to keep every page table entry in 32-bits, this patch re-used the
existing - but yet unused - _PAGE_DMB flag (which triggers a hardware break
if a page is accessed) to store the special bit.

But when graphics card memory is mmapped into userspace, the kernel uses
vm_iomap_memory() which sets the the special flag. So, with the DMB bit
set, every access to the graphics memory now triggered a hardware
exception and segfaulted the userspace program.

Fix this breakage by dropping the DMB bit when writing the page
protection bits to the CPU TLB.

In addition this patch adds a small optimization: if huge pages aren't
configured (which is at least the case for 32-bit kernels), then the
special bit is stored in the hpage (HUGE PAGE) bit instead. That way we
can skip to reset the DMB bit.

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.

* 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.

  riscv: Allow PROT_WRITE-only mmap()
  riscv: Make VM_WRITE imply VM_READ

The PLIC specification does not describe the interrupt pendings bits as
read-write, only that they "can be read". To allow for retriggering of
interrupts (and the use of the irq debugfs interface) enable
HARDIRQS_SW_RESEND for RISC-V.

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.

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.
