Subject: [PATCH] f2fs: use lock_buffer when changing superblock
When modifying sb contents, we need to use
With device tree it is no more possible to reset the PHY at board
level. Furthermore, doing in the driver allow to power down the PHY when
the network interface is no more used.
The patch introduces a new optional property "phy-reset-gpio" inspired
from the one use for the FEC.

This patch-set fixes issues found in the pfn tracking code of PAT
when mremap() is used on a VM_PFNMAP range.
Patch 1/2 changes untrack_pfn() to handle the case of mremap() with
MREMAP_FIXED, i.e. remapping virtual address on a VM_PFNMAP range.
Patch 2/2 changes the free_memtype() path to handle
mremap() with MREMAP_FIXED, remapping to a new virtual address, on
a VM_PFNMAP range causes the following WARN_ON_ONCE() message in
untrack_pfn().
WARNING: CPU: 1 PID: 3493 at arch/x86/mm/pat.c:985 untrack_pfn+0xbd/0xd0()
Call Trace:
[] dump_stack+0x45/0x57

mremap() to shrink the map size of a VM_PFNMAP range causes
the following error message, and leaves the pfn range allocated.

When CONFIG_DEBUG_ICEDCC is set, we don't use the platform
specific putc() function, but use icedcc_putc() instead, so
putc is unused and causes a compile time warning:
In file included from ../arch/arm/boot/compressed/misc.c:28:0:
arch/arm/mach-rpc/include/mach/uncompress.h:79:13: warning:
The ACPI compiler uses the extended format when used interrupt numbers
are greater than 15. The extended IRQ syntax is 32 bits according to the
ACPI spec. The code supports parsing the extended interrupt numbers.
However, due to used data structure type; the code silently truncates
interrupt
Code currently supports 256 maximum interrupts at this moment. The patch is
reconfiguring the penalty array as a dynamic list to remove this
limitation.
A new penalty linklist has been added for all other interrupts greater than
16. If an IRQ is not found in the link list, an IRQ info structure

Patches just got merged into mainline. Please let me know if the
current git master doesn't fix the issue.

Hi Greg,
Here's what I hope to be the last set of fixes for current -rc. Let me
know if you want anything to be changed.

The bootloader is charged with the responsibility to provide platform
specific Dynamic Voltage and Frequency Scaling (DVFS) information via
Device Tree. This driver takes the supplied configuration and
registers it with the new generic OPP framework, to then be used with
CPUFreq.

Hi Linus,
These are more fixes I'd like to have in v4.4. Several for the Altera
driver added for v4.4, and one for an MSI domain problem that affects
several arm64 platforms.
