The dgnc driver has no business creating "custom" sysfs files just for a
single tty driver. Combined with the odd way they are created, it's
just a mess, so remove them entirely as I am tired of tripping over them
when doing driver core changes.

This moves the prototypes for functions that are only called from
assembler code out of asm/asm-prototypes.h into asm/kvm_ppc.h.
The prototypes were added in commit ebe4535fbe7a ("KVM: PPC:
Book3S HV: sparse: prototypes for functions called from assembler",
2016-10-10), but given that the functions are KVM functions,
having them in a KVM header will be better for long-term
maintenance.

LSIs must be ack'ed with an MMIO otherwise they remain asserted
forever. This is controlled by the "clear_isr" flag.
While we set that flag properly when deciding initially whether to use
LSIs or MSIs, we fail to set it if we first chose MSIs, the test fails,
then fallback to LSIs.

We recently introduced a kfree() in the caller for this function.
That's where, logically, you would think the kfree() should be.
Unfortunately the code was just ugly and not buggy so the static checker
warning was a false postive and introduced a double free.
I've removed the old kfree() and left the new one.

Currently, when sending a SCSI command, the pointer is stored in a
reserved field of the AFU command descriptor for retrieval once the
SCSI command has completed. In order to support new descriptor formats
that make use of the reserved field, the pointer is migrated to outside
the descriptor where it can still be found during completion processing.

The queuecommand routine is disorganized where it populates the
private command and also contains some logic/statements that are
not needed given that cxlflash devices do not (and likely never
will) support scatter-gather.

The original design of the cxlflash driver required AFU commands
to convey state information across multiple threads. The IOASA
"host use" byte was used to track if a command was done, errored,
or timed out. A per-command spin lock was used to serialize access
to this byte. As this is no longer required with the introduction
of completions and various refactoring over time, the spin lock,
state tracking, and associated code can be removed. To support the
simplification, the wait_resp() routine is refactored to return a
success or failure. Additionally, as the simplification to the
AFU internal command routine, explicit assignments of AFU command
fields to zero are removed as the memory is zeroed upon allocation.

With the removal of the static private command pool, the ability to
'complete' outstanding commands was lost. While not an issue for the
commands originating outside the driver, internal AFU commands are
synchronous and therefore have a timeout associated with them. To
avoid a stale memory access, the tear down sequence needs to ensure
that there are not any active commands before proceeding. As these
internal AFU commands are rare events, the simplest way to accomplish
this is detecting the activity and waiting for it to timeout.

Instead of using a private pool of AFU commands, use cmd_size to prime
the private pool of SCSI commands such that they are allocated with a
size large enough to contain an aligned AFU command. Use scsi_cmd_priv()
to derive the aligned/zeroed private command on queuecommand and TMF
paths. Remove cmd_checkout() as it is no longer required. The remaining
AFU private command infrastructure will be removed in a cleanup commit.

The cxlflash driver originally required a per-command 4K buffer that
hosted data passed to the AFU. When the routines that initiate AFU
and internal SCSI commands were refactored to use scsi_execute(), the
need for this buffer became obsolete. As it is no longer necessary,
the buffer is removed.

Merge misc fixes from Andrew Morton:
"7 fixes"
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
mm: fix false-positive WARN_ON() in truncate/invalidate for hugetlb
kasan: support use-after-scope detection
kasan: update kasan_global for gcc 7
lib/debugobjects: export for use in modules
zram: fix unbalanced idr management at hot removal
thp: fix corner case of munlock() of PTE-mapped THPs
mm, thp: propagation of conditional compilation in khugepaged.c
|
|
Hugetlb pages have ->index in size of the huge pages (PMD_SIZE or
PUD_SIZE), not in PAGE_SIZE as other types of pages. This means we
cannot user page_to_pgoff() to check whether we've got the right page
for the radix-tree index.
Let's introduce page_to_index() which would return radix-tree index for
given page.
We will be able to get rid of this once hugetlb will be switched to
multi-order entries.

Drivers, or other modules, that use a mixture of objects (especially
objects embedded within other objects) would like to take advantage of
the debugobjects facilities to help catch misuse. Currently, the
debugobjects interface is only available to builtin drivers and requires
a set of EXPORT_SYMBOL_GPL for use by modules.
I am using the debugobjects in i915.ko to try and catch some invalid
operations on embedded objects. The problem currently only presents
itself across module unload so forcing i915 to be builtin is not an
option.

The zram hot removal code calls idr_remove() even when zram_remove()
returns an error (typically -EBUSY). This results in a leftover at the
device release, eventually leading to a crash when the module is
reloaded.
As described in the bug report below, the following procedure would
cause an Oops with zram:
- provision three zram devices via modprobe zram num_devices=3
- configure a size for each device
+ echo "1G" > /sys/block/$zram_name/disksize
- mkfs and mount zram0 only
- attempt to hot remove all three devices
+ echo 2 > /sys/class/zram-control/hot_remove
+ echo 1 > /sys/class/zram-control/hot_remove
+ echo 0 > /sys/class/zram-control/hot_remove
- zram0 removal fails with EBUSY, as expected
- unmount zram0
- try zram0 hot remove again
+ echo 0 > /sys/class/zram-control/hot_remove
- fails with ENODEV (unexpected)
- unload zram kernel module
+ completes successfully
- zram0 device node still exists
- attempt to mount /dev/zram0
+ mount command is killed
+ following BUG is encountered

The following program triggers BUG() in munlock_vma_pages_range():
// autogenerated by syzkaller (http://github.com/google/syzkaller)
#include <sys/mman.h>
int main()
{
mmap((void*)0x20105000ul, 0xc00000ul, 0x2ul, 0x2172ul, -1, 0);
mremap((void*)0x201fd000ul, 0x4000ul, 0xc00000ul, 0x3ul, 0x203f0000ul);
return 0;
}
The test-case constructs the situation when munlock_vma_pages_range()
finds PTE-mapped THP-head in the middle of page table and, by mistake,
skips HPAGE_PMD_NR pages after that.
As result, on the next iteration it hits the middle of PMD-mapped THP
and gets upset seeing mlocked tail page.
The solution is only skip HPAGE_PMD_NR pages if the THP was mlocked
during munlock_vma_page(). It would guarantee that the page is
PMD-mapped as we never mlock PTE-mapeed THPs.

Commit b46e756f5e47 ("thp: extract khugepaged from mm/huge_memory.c")
moved code from huge_memory.c to khugepaged.c. Some of this code should

this code was not moved into khugepaged.c.
The result is a compilation error when CONFIG_SYSFS is disabled:

mm/built-in.o: In function `khugepaged_defrag_show': khugepaged.c:(.text+0x2d0ab): undefined reference to `single_hugepage_flag_show'

Keeping both rst and in-file documentation in sync can be harsh.
So, simplify the script's internal documntation to a bare minimum,
and add a mention to the ReST file with its full documentation.
This way, a quick help is still available at the command line,
while the complete one is maintained at the ReST format.
As we won't be using pad2rst anymore, do a cleanup at the ReST

drm-next
On the userspace side, all the basics are working, and most of glmark2
is working. I've been working through deqp, and I've got a couple more
things to fix (but we've gone from 70% to 80+% pass in last day, and
current deqp run that is going should pick up another 5-10%). I expect
to push the mesa patches today or tomorrow.
There are a couple more a5xx related patches to take the gpu out of
secure mode (for the devices that come up in secure mode, like the hw
I have), but those depend on an scm patch that would come in through
another tree. If that can land in the next day or two, there might
be a second late pull request for drm/msm.
In addition to the new-shiny, there have also been a lot of overlay/
plane related fixes for issues found using drm-hwc2 (in the process of
testing/debugging the atomic/kms fence patches), resulting in rework
to assign hwpipes to kms planes dynamically (as part of global atomic
state) and also handling SMP (fifo) block allocation atomically as
part of the ->atomic_check() step. All those patches should also help

The PCIe root complex on Juno translates the MMIO mapped
at 0x5f800000 to the PIO address range starting at 0
(which is common because PIO addresses are generally < 64k).
Correct the DT to reflect this.
