commit 3641762c1c9c7cfd84a7061a0a73054f09b412e3 upstream.
Before this commit lis3lv02d_get_pwron_wait() had a WARN_ONCE() to catch
a potential divide by 0. WARN macros should only be used to catch internal
kernel bugs and that is not the case here. We have been receiving a lot of
bug reports about kernel backtraces caused by this WARN.
The div value being checked comes from the lis3->odrs[] array. Which
is sized to be a power-of-2 matching the number of bits in lis3->odr_mask.
The only lis3 model where this array is not entirely filled with non zero
values. IOW the only model where we can hit the div == 0 check is the
3dc ("8 bits 3DC sensor") model:
int lis3_3dc_rates[16] = {0, 1, 10, 25, 50, 100, 200, 400, 1600, 5000};
Note the 0 value at index 0, according to the datasheet an odr index of 0
means "Power-down mode". HP typically uses a lis3 accelerometer for HDD
fall protection. What I believe is happening here is that on newer
HP devices, which only contain a SDD, the BIOS is leaving the lis3 device
powered-down since it is not used for HDD fall protection.
Note that the lis3_3dc_rates array initializer only specifies 10 values,
which matches the datasheet. So it also contains 6 zero values at the end.
Replace the WARN with a normal check, which treats an odr index of 0
as power-down and uses a normal dev_err() to report the error in case
odr index point past the initialized part of the array.

[ Upstream commit f6f1f8e6e3eea25f539105d48166e91f0ab46dd1 ]
A dummy zero bit is sent preceding the data during a read transfer by the
Microchip 93LC46B eeprom (section 2.7 of[1]). This results in right shift
of data during a read. In order to ignore this bit a quirk can be added to
send an extra zero bit after the read address.
Add a quirk to ignore the zero bit sent before data by adding a zero bit
after the read address.

commit 3f618ab3323407ee4c6a6734a37eb6e9663ebfb9 upstream.
When building with KASAN and LKDTM, clang may implictly generate an
asan.module_ctor function in the LKDTM rodata object. The Makefile moves
the lkdtm_rodata_do_nothing() function into .rodata by renaming the
file's .text section to .rodata, and consequently also moves the ctor
function into .rodata, leading to a boot time crash (splat below) when
the ctor is invoked by do_ctors().
Let's prevent this by marking the function as noinstr rather than
notrace, and renaming the file's .noinstr.text to .rodata. Marking the
function as noinstr will prevent tracing and kprobes, and will inhibit
any undesireable compiler instrumentation.
The ctor function (if any) will be placed in .text and will work
correctly.
Example splat before this patch is applied:

When doing dma_alloc_coherent in the driver, we add a certain hard-coded
offset to the DMA address before returning to the callee function. This
offset is needed when our device use this DMA address to perform
outbound transactions to the host.
However, if we want to map the DMA'able memory to the user via
dma_mmap_coherent(), we need to pass the original dma address, without
this offset. Otherwise, we will get erronouos mapping.

When the firmware security is enabled, the pcie_aux_dbi_reg_addr
register in the PCI controller is blocked. Therefore, ignore
the result of writing to this register and assume it worked. Also
remove the prints on errors in the internal ELBI write function.
If the security is enabled, the firmware is responsible for setting
this register correctly so we won't have any problem.
If the security is disabled, the write will work (unless something
is totally broken at the PCI level and then the whole sequence
will fail).
In addition, remove a write to register pcie_aux_dbi_reg_addr+4,
which was never actually needed.
Moreover, PCIE_DBI registers are blocked to access from host when
firmware security is enabled. Use a different register to flush the
writes.

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into i2c/for-current
at24 fixes for v5.10
- fix NVMEM name with custom AT24 device name
|
|
This reverts commit d162219c655c8cf8003128a13840d6c1e183fb80.
The device uses a VIRTIO device ID out of a not-for-production range.
Releasing Linux using an ID out of this range will make it conflict with
development setups. An official request to reserve an ID for an MEI
device is yet to be submitted to the virtio TC, thus there's no chance
it will be reserved and fixed in time before the next release.
Once requested it usually takes 2-3 weeks to land in the spec, which
means the device can be supported with the official ID in the next Linux
version if contributors act quickly.

All throughout the driver, normal kernel pointers are
stored as 'u64' struct members, which is kind of silly
and requires casting through a uintptr_t to void* every
time they are used.
There is one line that missed the intermediate uintptr_t
case, which leads to a compiler warning:
drivers/misc/habanalabs/common/command_buffer.c: In function 'hl_cb_mmap':
drivers/misc/habanalabs/common/command_buffer.c:512:44: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

Pull char/misc fixes/removals from Greg KH:
"Here's some small fixes for 5.10-rc2 and a big driver removal.
The fixes are for some reported issues in the interconnect and
coresight drivers, nothing major.
The "big" driver removal is the MIC drivers have been asked to be
removed as the hardware never shipped and Intel no longer wants to
maintain something that no one can use. This is welcomed by many as
the DMA usage of these drivers was "interesting" and the security
people were starting to question some issues that were starting to be
found in the codebase.
Note, one of the subsystems for this driver, the "VOP" code, will
probably come back in future kernel versions as it was looking to
potentially solve some PCIe virtualization issues that a number of
other vendors were wanting to solve. But as-is, this codebase didn't
work for anyone else so no actual functionality is being removed.
All of these have been in linux-next with no reported issues"

There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code should
always use “flexible array members”[1] for these cases. The older style of
one-element or zero-length arrays should no longer be used[2].

This patch removes the MIC drivers from the kernel tree
since the corresponding devices have been discontinued.
Removing the dma and char-misc changes in one patch and
merging via the char-misc tree is best to avoid any
potential build breakage.

Pull powerpc updates from Michael Ellerman:
- A series from Nick adding ARCH_WANT_IRQS_OFF_ACTIVATE_MM & selecting
it for powerpc, as well as a related fix for sparc.
- Remove support for PowerPC 601.
- Some fixes for watchpoints & addition of a new ptrace flag for
detecting ISA v3.1 (Power10) watchpoint features.
- A fix for kernels using 4K pages and the hash MMU on bare metal
Power9 systems with > 16TB of RAM, or RAM on the 2nd node.
- A basic idle driver for shallow stop states on Power10.
- Tweaks to our sched domains code to better inform the scheduler about
the hardware topology on Power9/10, where two SMT4 cores can be
presented by firmware as an SMT8 core.
- A series doing further reworks & cleanups of our EEH code.
- Addition of a filter for RTAS (firmware) calls done via sys_rtas(),
to prevent root from overwriting kernel memory.
- Other smaller features, fixes & cleanups.
