Merge misc fixes from ANdrew Morton:
"8 fixes"
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
revert "mm: make sure all file VMAs have ->vm_ops set"
MAINTAINERS: update LTP mailing list

alpha: io: define ioremap_uc
kasan: fix last shadow judgement in memory_is_poisoned_16()
zram: fix possible use after free in zcomp_create()
|
|
zcomp_create() verifies the success of zcomp_strm_{multi,single}_create()
through comp->stream, which can potentially be pointing to memory that
was freed if these functions returned an error.
While at it, replace a 'ERR_PTR(-ENOMEM)' by a more generic
'ERR_PTR(error)' as in the future zcomp_strm_{multi,siggle}_create()
could return other error codes. Function documentation updated
accordingly.

Do not write initialize magic on systems that do not have
feature query 0xb. Fixes Bug #82451.
Redefine FEATURE_QUERY to align with 0xb and FEATURE2 with 0xd
for code clearity.
Add a new test function, hp_wmi_bios_2008_later() & simplify
hp_wmi_bios_2009_later(), which fixes a bug in cases where
an improper value is returned. Probably also fixes Bug #69131.

A recent change in gcc caused this build failure:
/var/lib/jenkins/workspace/gcc_kernel_build/linux/drivers/misc/cxl/cxl.h:72:27:
error: ‘CXL_PSL_DLCNTL’ defined but not used [-Werror=unused-const-variable]
static const cxl_p1_reg_t CXL_PSL_DLCNTL = {0x0060};
Because of this gcc commit:
Commit 1bca8cbd0c68366f07277f98ce6963e10c2aa617 by mark
PR28901 -Wunused-variable ignores unused const initialised variables in C
12 years ago it was decided that -Wunused-variable shouldn't warn about
static const variables because some code used const static char rcsid[]
strings which were never used but wanted in the code anyway. But as the
bug points out this hides some real bugs. These days the usage of
rcsids is not very popular anymore. So this patch changes the default
to warn about unused static const variables in C with
-Wunused-variable. And it adds a new option -Wno-unused-const-variable
to turn this warning off. For C++ this new warning is off by default,
since const variables can be used as #defines in C++. New testcases for
the new defaults in C and C++ are included testing the new warning and
suppressing it with an unused attribute or using
-Wno-unused-const-variable. gcc/ChangeLog
The cxl driver uses static consts in place of #defines in some cases
for type safety, so this change causes the driver to fail to build on
new copilers as these constants are not all used in every file that
imports the header. Suppress the warning for this driver to return to
the old behaviour of -Wunused-variable.

Currently the first thing we do in cxl_probe is to grab a reference
on the pci device. Later on, we call device_register on our adapter.
In our remove path, we call device_unregister, but we never call
pci_dev_put. We therefore leak the device every time we do a
reflash.
device_register/unregister is sufficient to hold the reference.
Therefore, drop the call to pci_dev_get.
Here's why this is safe.
The proposed cxl_probe(pdev) calls cxl_adapter_init:
a) init calls cxl_adapter_alloc, which creates a struct cxl,
conventionally called adapter. This struct contains a
device entry, adapter->dev.
b) init calls cxl_configure_adapter, where we set
adapter->dev.parent = &dev->dev (here dev is the pci dev)
So at this point, the cxl adapter's device's parent is the PCI
device that I want to be refcounted properly.
c) init calls cxl_register_adapter
*) cxl_register_adapter calls device_register(&adapter->dev)
So now we're in device_register, where dev is the adapter device, and
we want to know if the PCI device is safe after we return.
device_register(&adapter->dev) calls device_initialize() and then
device_add().
device_add() does a get_device(). device_add() also explicitly grabs
the device's parent, and calls get_device() on it:
parent = get_device(dev->parent);
So therefore, device_register() takes a lock on the parent PCI dev,
which is what pci_dev_get() was guarding. pci_dev_get() can therefore
be safely removed.

where the get() operation will fail to acquire a readout of the current

act on, retry or ignore these failing reads, instead of treating them as

I didn't notice this when merging the thermal code from Zhang, but his
merge (commit 5a924a07f882: "Merge branches 'thermal-core' and
'thermal-intel' of .git into next") of the thermal-core and
thermal-intel branches was wrong.
In thermal-core, commit 17e8351a7739 ("thermal: consistently use int for
temperatures") converted the thermal layer to use "int" for
temperatures.
But in parallel, in the thermal-intel branch commit d0a12625d2ff
("thermal: Add Intel PCH thermal driver") added support for the intel
PCH thermal sensor using the old interfaces that used "unsigned long"
pointers.
This resulted in warnings like this:
drivers/thermal/intel_pch_thermal.c:184:14: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
.get_temp = pch_thermal_get_temp,
^
drivers/thermal/intel_pch_thermal.c:184:14: note: (near initialization for ‘tzd_ops.get_temp’)

.get_trip_temp = pch_get_trip_temp,

Pull SCSI target updates from Nicholas Bellinger:
"Here are the outstanding target-pending updates for v4.3-rc1.
Mostly bug-fixes and minor changes this round. The fallout from the
big v4.2-rc1 RCU conversion have (thus far) been minimal.
The highlights this round include:
- Move sense handling routines into scsi_common code (Sagi)
- Return ABORTED_COMMAND sense key for PI errors (Sagi)
- Add tpg_enabled_sendtargets attribute for disabled iscsi-target
discovery (David)
- Shrink target struct se_cmd by rearranging fields (Roland)
- Drop iSCSI use of mutex around max_cmd_sn increment (Roland)
- Replace iSCSI __kernel_sockaddr_storage with sockaddr_storage (Andy +
Chris)
- Honor fabric max_data_sg_nents I/O transfer limit (Arun + Himanshu +
nab)
- Fix EXTENDED_COPY >= v4.1 regression OOPsen (Alex + nab)"

integration between scsi and scsi_dh (the device handling layer used
by multi-path; all the dm parts are acked by Mike Snitzer).
This also includes driver updates for mp3sas, scsi_debug and an
assortment of bug fixes"

The seq_<foo> function return values were frequently misused.
See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
seq_has_overflowed() and make public")
All uses of these return values have been removed, so convert the
return types to void.
Miscellanea:
o Move seq_put_decimal_<type> and seq_escape prototypes closer the
other seq_vprintf prototypes
o Reorder seq_putc and seq_puts to return early on overflow
o Add argument names to seq_vprintf and seq_printf
o Update the seq_escape kernel-doc
o Convert a couple of leading spaces to tabs in seq_escape

The ehca driver is only supported on IBM machines with a custom EBus.
As they have opted to build their newer machines using more industry
standard technology and haven't really been pushing EBus capable
machines for a while, this driver can now safely be moved to the
staging area and scheduled for eventual removal. This plan was brought
to IBM's attention and received their sign-off.

It looks like the Kconfig check that was meant to fix this (commit
fe9233fb6914a0eb20166c967e3020f7f0fba2c9 [SCSI] scsi_dh: fix kconfig related
build errors) was actually reversed, but no-one noticed until the new set of
patches which separated DM and SCSI_DH).

Calling transport_generic_request_failure() from here causes list

Which we do in all other cases, so the UNKNOWN_OP case can become just
another member of the big else/if chain in tcmu_handle_completion().
