Subject: gpio: mvebu: only fail on missing clk if pwm is actually to be used
|
||||
Origin: http://lists.infradead.org/pipermail/linux-arm-kernel/2018-December/621248.html
|
||||
|
||||
The gpio IP on Armada 370 at offset 0x18180 has neither a clk nor pwm
|
||||
registers. So there is no need for a clk as the pwm isn't used anyhow.
|
||||
So only check for the clk in the presence of the pwm registers. This fixes
|
||||
a failure to probe the gpio driver for the above mentioned gpio device.

Subject: x86/mm: Fix guard hole handling
|
||||
Origin: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=16877a5570e0c5f4270d5b17f9bab427bcae9514
|
||||
|
||||
There is a guard hole at the beginning of the kernel address space, also
|
||||
used by hypervisors. It occupies 16 PGD entries.
|
||||
|
||||
This reserved range is not defined explicitely, it is calculated relative
|
||||
to other entities: direct mapping and user space ranges.
|
||||
|
||||
The calculation got broken by recent changes of the kernel memory layout:
|
||||
LDT remap range is now mapped before direct mapping and makes the
|
||||
calculation invalid.
|
||||
|
||||
The breakage leads to crash on Xen dom0 boot[1].
|
||||
|
||||
Define the reserved range explicitely. It's part of kernel ABI (hypervisors
|
||||
expect it to be stable) and must not depend on changes in the rest of
|
||||
kernel memory layout.
