The SMN (System Management Network) on Family 17h AMD CPUs is also accessed
from other drivers, specifically EDAC. Accessing it directly is racy.
On top of that, accessing the SMN through root bridge 00:00 is wrong on
multi-die CPUs and may result in reading the temperature from the wrong

New devices launching with Android P need to use the 64-bit
binder interface, even on 32-bit SoCs [0].
This change removes the Kconfig option to select the 32-bit
binder interface. We don't think this will affect existing
userspace for the following reasons:
1) The latest Android common tree is 4.

Instead of directly warn on wrong context, check if softirq context is
set. This check could be a nop on RT.

pageout() in MM traslates EAGAIN, so calls handle_write_error()
-> mapping_set_error() -> set_bit(AS_EIO, ...).
file_write_and_wait_range() will see EIO error, which is critical
to return value of fsync() followed by atomic_write failure to user.

ieee80211_rx_napi() has a check to ensure that it is invoked in softirq
context / with BH disabled. It is there because it invokes
netif_receive_skb() which has this requirement.
On -RT this check does not work as expected so there is always this
warning.

Hi Lin,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on rockchip/for-next]
[also build test WARNING on v4.17-rc3 next-20180504]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system]

This should let us associate enum kdoc to these values.
While at it, kdocify the fw_opt.

This is done since this call is now exposed through kernel-doc,

I noticed that unused UARTs won't necessarily idle properly always
unless at least one byte tx transfer is done first.
After some debugging I narrowed down the problem to the scr register
dma configuration bits that need to be set before softreset for the
clocks to idle. Unless we do this, the mod
If you try to read FW_LOADER today it speaks of old riddles and
unless you have been following development closely you will loose
track of what is what. Even the documentation for PREVENT_FIRMWARE_BUILD
is a bit fuzzy and how it fits into this big picture.

d random folks of firmware reviewer folks.
These patches are based on top of linux-next next-20180504, they are
also available in a respective git branch, both for linux-next [1] and
linux [2].
Question, and specially rants are greatly appreciated, and of course...
may the 4th be with you.

Currently a number of arm64-specific files include for

Currently only instruments the fully
ordered variants of atomic functions, ignoring the {relaxed,acquire,release}
ordering variants.
This patch reworks the header to instrument all ordering variants of the atomic
functions, so that architectures implementing these are instrumented
appropriately.
As our atomics are written in inline assembly, they don't get
instrumented when we enable KASAN, and thus we can miss when they are
used on erroneous memory locations.
As with x86, let's use atomic-instrumented.h to give arm64 instrumented
atomics. This requires that we add an arch_ prefix to our
Our __smp_store_release() and __smp_load_acquire() macros use inline
assembly, which is opaque to kasan. This means that kasan can't catch
erroneous use of these.
This patch adds kasan instrumentation to both.
It might be better to turn these into __arch_* variants, as we do for
the atomics, but
