Using hypercall for sending IPIs is faster because this allows to specify

ISPIF hardware modules on 8x16 and 8x96 are similar. However on
8x96 the ISPIF routes data to two VFE hardware modules. Add
separate interrupt handler for 8x96 to handle the additional
interrupts.

Printing "err 0" to the user in the warning message is not particularly
useful, especially when this gets transformed into a -ENOENT for the

KASAN depends on having access to some of the accounting that SLUB_DEBUG
does; without it, there are immediate crashes [1]. So, the natural thing
to do is to make KASAN select SLUB_DEBUG.

Hmm, fair enough. I think a better heuristic would be if the
estimated idle duration is more than, say, 10ms. I *think* the code
has been cleaned up enough that this is easy now. (Using time instead
of C6 will make it a lot less dependent on which idle driver is in
use.)

Commit 30f9f2fb7ba0 ("mtd: denali: add a DT driver") supported the
clock enablement, but did not document it in the DT binding.
In addition to the existing clock, this commit adds more clocks based
on the IP specification.
According to the Denali User's Guide, this IP needs three clocks:
-
This commit improves the ->setup_data_interface() hook.
The denali_setup_data_interface() needs the frequency of clk_x
and the ratio of clk_x / clk.
The latter is currently hardcoded in the driver, like this:
#define DENALI_CLK_X_MULT 6
The IP datasheet requires that clk_x / clk be 4,
Since commit 1bb88666775e ("mtd: nand: denali: handle timing parameters
by setup_data_interface()"), denali_dt.c gets the clock rate from the
clock driver. The driver expects the frequency of the bus interface
clock, whereas the clock driver of SOCFPGA provides the core clock.

Commit ac75a041048b ("HID: i2c-hid: fix size check and type usage")
started writing messages when the ret_size is <= 2 from i2c_master_recv.
However, my device i2c-DLL07D1 returns 2 for a short period of time
(~0.5s) after I stop moving the pointing stick or touchpad. It varies,
but you get ~50

There is no real reason to blow up just because the caller doesn't know
that __get_free_pages cannot return highmem pages. Simply fix that up
silently. Even if we have some confused users such a fixup will not be
harmful.

Rather than accessing the TPM functions by passing a NULL pointer for
the tpm_chip, which causes a lookup for a suitable chip every time, get a
hold of a tpm_chip and access the TPM functions using it.

This series of patches converts IMA's usage of the tpm_chip to find a TPM
chip initially and use it until the machine is shut down. To do this we need
to introduce a kref for the tpm_chip that IMA and all other users of a
tpm_chip hold onto until they don't need the TPM chip anymore.

Implement tpm_chip_find() for other subsystems to find a TPM chip and
get a reference to that chip.

Rename tpm_chip_find_get() to tpm_get_ops(). This now matches
the name of its counter part tpm_put_ops() better.
