parisc: Try to fix random segmentation faults in package builds

commit 72d95924ee35c8cd16ef52f912483ee938a34d49 upstream.

PA-RISC systems with PA8800 and PA8900 processors have had problems
with random segmentation faults for many years. Systems with earlier
processors are much more stable.

Systems with PA8800 and PA8900 processors have a large L2 cache which
needs per page flushing for decent performance when a large range is
flushed. The combined cache in these systems is also more sensitive to
non-equivalent aliases than the caches in earlier systems.

The majority of random segmentation faults that I have looked at
appear to be memory corruption in memory allocated using mmap and
malloc.

My first attempt at fixing the random faults didn't work. On
reviewing the cache code, I realized that there were two issues
which the existing code didn't handle correctly. Both relate
to cache move-in. Another issue is that the present bit in PTEs
is racy.

1) PA-RISC caches have a mind of their own and they can speculatively
load data and instructions for a page as long as there is a entry in
the TLB for the page which allows move-in. TLBs are local to each
CPU. Thus, the TLB entry for a page must be purged before flushing
the page. This is particularly important on SMP systems.

In some of the flush routines, the flush routine would be called
and then the TLB entry would be purged. This was because the flush
routine needed the TLB entry to do the flush.

2) My initial approach to trying the fix the random faults was to
try and use flush_cache_page_if_present for all flush operations.
This actually made things worse and led to a couple of hardware
lockups. It finally dawned on me that some lines weren't being
flushed because the pte check code was racy. This resulted in
random inequivalent mappings to physical pages.

The __flush_cache_page tmpalias flush sets up its own TLB entry
and it doesn't need the existing TLB entry. As long as we can find
the pte pointer for the vm page, we can get the pfn and physical
address of the page. We can also purge the TLB entry for the page
before doing the flush. Further, __flush_cache_page uses a special
TLB entry that inhibits cache move-in.

When switching page mappings, we need to ensure that lines are
removed from the cache. It is not sufficient to just flush the
lines to memory as they may come back.

This made it clear that we needed to implement all the required
flush operations using tmpalias routines. This includes flushes
for user and kernel pages.

After modifying the code to use tmpalias flushes, it became clear
that the random segmentation faults were not fully resolved. The
frequency of faults was worse on systems with a 64 MB L2 (PA8900)
and systems with more CPUs (rp4440).

The warning that I added to flush_cache_page_if_present to detect
pages that couldn't be flushed triggered frequently on some systems.

Helge and I looked at the pages that couldn't be flushed and found
that the PTE was either cleared or for a swap page. Ignoring pages
that were swapped out seemed okay but pages with cleared PTEs seemed
problematic.

I looked at routines related to pte_clear and noticed ptep_clear_flush.
The default implementation just flushes the TLB entry. However, it was
obvious that on parisc we need to flush the cache page as well. If
we don't flush the cache page, stale lines will be left in the cache
and cause random corruption. Once a PTE is cleared, there is no way
to find the physical address associated with the PTE and flush the
associated page at a later time.

I implemented an updated change with a parisc specific version of
ptep_clear_flush. It fixed the random data corruption on Helge's rp4440
and rp3440, as well as on my c8000.

At this point, I realized that I could restore the code where we only
flush in flush_cache_page_if_present if the page has been accessed.
However, for this, we also need to flush the cache when the accessed
bit is cleared in ptep_clear_flush_young to keep things synchronized.
The default implementation only flushes the TLB entry.

Other changes in this version are:

1) Implement parisc specific version of ptep_get. It's identical to
default but needed in arch/parisc/include/asm/pgtable.h.
2) Revise parisc implementation of ptep_test_and_clear_young to use
ptep_get (READ_ONCE).
3) Drop parisc implementation of ptep_get_and_clear. We can use default.
4) Revise flush_kernel_vmap_range and invalidate_kernel_vmap_range to
use full data cache flush.
5) Move flush_cache_vmap and flush_cache_vunmap to cache.c. Handle
VM_IOREMAP case in flush_cache_vmap.

At this time, I don't know whether it is better to always flush when
the PTE present bit is set or when both the accessed and present bits
are set. The later saves flushing pages that haven't been accessed,
but we need to flush in ptep_clear_flush_young. It also needs a page
table lookup to find the PTE pointer. The lpa instruction only needs
a page table lookup when the PTE entry isn't in the TLB.

We don't atomically handle setting and clearing the _PAGE_ACCESSED bit.
If we miss an update, we may miss a flush and the cache may get corrupted.
Whether the current code is effectively atomic depends on process control.

When CONFIG_FLUSH_PAGE_ACCESSED is set to zero, the page will eventually
be flushed when the PTE is cleared or in flush_cache_page_if_present. The
_PAGE_ACCESSED bit is not used, so the problem is avoided.

The flush method can be selected using the CONFIG_FLUSH_PAGE_ACCESSED
define in cache.c. The default is 0. I didn't see a large difference
in performance.

parisc: Fix random data corruption from exception handler

parisc: Fix random data corruption from exception handler

commit 8b1d72395635af45410b66cc4c4ab37a12c4a831 upstream.

The current exception handler implementation, which assists when accessing
user space memory, may exhibit random data corruption if the compiler decides
to use a different register than the specified register %r29 (defined in
ASM_EXCEPTIONTABLE_REG) for the error code. If the compiler choose another
register, the fault handler will nevertheless store -EFAULT into %r29 and thus
trash whatever this register is used for.
Looking at the assembly I found that this happens sometimes in emulate_ldd().

To solve the issue, the easiest solution would be if it somehow is
possible to tell the fault handler which register is used to hold the error
code. Using %0 or %1 in the inline assembly is not posssible as it will show
up as e.g. %r29 (with the "%r" prefix), which the GNU assembler can not
convert to an integer.

This patch takes another, better and more flexible approach:
We extend the __ex_table (which is out of the execution path) by one 32-word.
In this word we tell the compiler to insert the assembler instruction
"or %r0,%r0,%reg", where %reg references the register which the compiler
choosed for the error return code.
In case of an access failure, the fault handler finds the __ex_table entry and
can examine the opcode. The used register is encoded in the lowest 5 bits, and
the fault handler can then store -EFAULT into this register.

Since we extend the __ex_table to 3 words we can't use the BUILDTIME_TABLE_SORT
config option any longer.

parisc: BTLB: Fix crash when setting up BTLB at CPU bringup

commit 913b9d443a0180cf0de3548f1ab3149378998486 upstream.

When using hotplug and bringing up a 32-bit CPU, ask the firmware about the
BTLB information to set up the static (block) TLB entries.

For that write access to the static btlb_info struct is needed, but
since it is marked __ro_after_init the kernel segfaults with missing
write permissions.

Fix the crash by dropping the __ro_after_init annotation.
