Borislav Petkov 8877ebdd3f x86/microcode/AMD: Reload proper initrd start address
When we switch to virtual addresses and, especially after
reserve_initrd()->relocate_initrd() have run, we have the updated initrd
address in initrd_start. Use initrd_start then instead of the address
which has been passed to us through boot params. (That still gets used
when we're running the very early routines on the BSP).

Paul Burton e85baa8868 mmc: sd: Meet alignment requirements for raw_ssr DMA
The mmc_read_ssr() function results in DMA to the raw_ssr member of
struct mmc_card, which is not guaranteed to be cache line aligned & thus
might not meet the requirements set out in Documentation/DMA-API.txt:

  Warnings:  Memory coherency operates at a granularity called the cache
  line width.  In order for memory mapped by this API to operate
  correctly, the mapped region must begin exactly on a cache line
  boundary and end exactly on one (to prevent two separately mapped
  regions from sharing a single cache line).  Since the cache line size
  may not be known at compile time, the API will not enforce this
  requirement.  Therefore, it is recommended that driver writers who
  don't take special care to determine the cache line size at run time
  only map virtual regions that begin and end on page boundaries (which
  are guaranteed also to be cache line boundaries).

On some systems where DMA is non-coherent this can lead to us losing
data that shares cache lines with the raw_ssr array.

Fix this by kmalloc'ing a temporary buffer to perform DMA into. kmalloc
will ensure the buffer is suitably aligned, allowing the DMA to be
performed without any loss of data.

Arnd Bergmann adec57c61c cpufreq: s3c64xx: remove incorrect __init annotation
s3c64xx_cpufreq_config_regulator is incorrectly annotated
as __init, since the caller is also not init:

WARNING: vmlinux.o(.text+0x92fe1c): Section mismatch in reference from the function s3c64xx_cpufreq_driver_init() to the function .init.text:s3c64xx_cpufreq_config_regulator()

With modern gcc versions, the function gets inline, so we don't
see the warning, this only happens with gcc-4.6 and older.

Boris Ostrovsky 2a8fa123d9 cpufreq: Remove CPU hotplug callbacks only if they were initialized
Since CPU hotplug callbacks are requested for CPUHP_AP_ONLINE_DYN state,
successful callback initialization will result in cpuhp_setup_state()
returning a positive value. Therefore acpi_cpufreq_online being zero
indicates that callbacks have not been installed.

This means that acpi_cpufreq_boost_exit() should only remove them if
acpi_cpufreq_online is positive. Trying to call
cpuhp_remove_state_nocalls(0) will cause a BUG().

Lv Zheng 8d3523fb3b ACPI / osl: Remove deprecated acpi_get_table_with_size()/early_acpi_os_unmap_memory()
Since all users are cleaned up, remove the 2 deprecated APIs due to no
users.
As a Linux variable rather than an ACPICA variable, acpi_gbl_permanent_mmap
is renamed to acpi_permanent_mmap to have a consistent coding style across
entire Linux ACPI subsystem.

Lv Zheng 6b11d1d677 ACPI / osl: Remove acpi_get_table_with_size()/early_acpi_os_unmap_memory() users
This patch removes the users of the deprectated APIs:
 acpi_get_table_with_size()
 early_acpi_os_unmap_memory()
The following APIs should be used instead of:
 acpi_get_table()
 acpi_put_table()

The deprecated APIs are invented to be a replacement of acpi_get_table()
during the early stage so that the early mapped pointer will not be stored
in ACPICA core and thus the late stage acpi_get_table() won't return a
wrong pointer. The mapping size is returned just because it is required by
early_acpi_os_unmap_memory() to unmap the pointer during early stage.

But as the mapping size equals to the acpi_table_header.length
(see acpi_tb_init_table_descriptor() and acpi_tb_validate_table()), when
such a convenient result is returned, driver code will start to use it
instead of accessing acpi_table_header to obtain the length.

Thus this patch cleans up the drivers by replacing returned table size with
acpi_table_header.length, and should be a no-op.

ACPICA commit d98de9ca14891130efc5dcdc871b97eb27b4b0f5

FADT parsing code requires FADT to be installed as
ACPI_TABLE_ORIGIN_INTERNAL_PHYSICAL, using new
acpi_tb_get_table()/acpi_tb_put_table(), other address types can also be allowed,
thus facilitates FADT customization with virtual address. Lv Zheng.

Lv Zheng 174cc7187e ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel
ACPICA commit cac6790954d4d752a083e6122220b8a22febcd07

This patch back ports Linux acpi_get_table_with_size() and
early_acpi_os_unmap_memory() into ACPICA upstream to reduce divergences.

The 2 APIs are used by Linux as table management APIs for long time, it
contains a hidden logic that during the early stage, the mapped tables
should be unmapped before the early stage ends.

During the early stage, tables are handled by the following sequence:
 acpi_get_table_with_size();
 parse the table
 early_acpi_os_unmap_memory();
During the late stage, tables are handled by the following sequence:
 acpi_get_table();
 parse the table
Linux uses acpi_gbl_permanent_mmap to distinguish the early stage and the
late stage.

The reasoning of introducing acpi_get_table_with_size() is: ACPICA will
remember the early mapped pointer in acpi_get_table() and Linux isn't able to
prevent ACPICA from using the wrong early mapped pointer during the late
stage as there is no API provided from ACPICA to be an inverse of
acpi_get_table() to forget the early mapped pointer.

But how ACPICA can work with the early/late stage requirement? Inside of
ACPICA, tables are ensured to be remained in "INSTALLED" state during the
early stage, and they are carefully not transitioned to "VALIDATED" state
until the late stage. So the same logic is in fact implemented inside of
ACPICA in a different way. The gap is only that the feature is not provided
to the OSPMs in an accessible external API style.

It then is possible to fix the gap by providing an inverse of
acpi_get_table() from ACPICA, so that the two Linux sequences can be
combined:
 acpi_get_table();
 parse the table
 acpi_put_table();
In order to work easier with the current Linux code, acpi_get_table() and
acpi_put_table() is implemented in a usage counting based style:
 1. When the usage count of the table is increased from 0 to 1, table is
    mapped and .Pointer is set with the mapping address (VALIDATED);
 2. When the usage count of the table is decreased from 1 to 0, .Pointer
    is unset and the mapping address is unmapped (INVALIDATED).
So that we can deploy the new APIs to Linux with minimal effort by just
invoking acpi_get_table() in acpi_get_table_with_size() and invoking
acpi_put_table() in early_acpi_os_unmap_memory(). Lv Zheng.

Helge Deller 160494d381 parisc: Optimize timer interrupt function
Restructure the timer interrupt function to better cope with missed timer irqs.
Optimize the calculation when the next interrupt should happen and skip irqs if
they would happen too shortly after exit of the irq function.

The update_process_times() call is done anyway at every timer irq, so we can
safely drop the prof_counter and prof_multiplier variables from the per_cpu
structure.

Since commit

  5a6681e22c ("sfc: separate out SFC4000 ("Falcon") support into new sfc-falcon driver")

there are two drivers for Solarflare devices, but both still show up
directly beneath "Ethernet driver support" in the Kconfig. Follow the
pattern of other vendors and group them beneath an own vendor Kconfig
entry for Solarflare.

Xin Long b8607805dd sctp: not copying duplicate addrs to the assoc's bind address list
sctp.local_addr_list is a global address list that is supposed to include
all the local addresses. sctp updates this list according to NETDEV_UP/
NETDEV_DOWN notifications.

However, if multiple NICs have the same address, the global list would
have duplicate addresses. Even if for one NIC, promote secondaries in
__inet_del_ifa can also lead to accumulating duplicate addresses.

When sctp binds address 'ANY' and creates a connection, it copies all
the addresses from global list into asoc's bind addr list, which makes
sctp pack the duplicate addresses into INIT/INIT_ACK packets.

This patch is to filter the duplicate addresses when copying the addrs
from global list in sctp_copy_local_addr_list and unpacking addr_param
from cookie in sctp_raw_to_bind_addrs to asoc's bind addr list.

Note that we can't filter the duplicate addrs when global address list
gets updated, As NETDEV_DOWN event may remove an addr that still exists
in another NIC.

====================
phy: Fix integration of eee-broken-modes

The purpose of this series is to fix the integration of the ethernet phy
property "eee-broken-modes" [0]

The v3 of this series has been merged, missing a fix (error reported by
kbuild robot) available in the v4 [1]

More importantly, Florian opposed adding a DT property mapping a device
register this directly [2]. The concern was that the property could be
abused to implement platform configuration policy. After discussing it,
I think we agreed that such information about the HW (defect) should appear
in the platform DT. However, the preferred way is to add a boolean property
for each EEE broken mode.

jbrunet 308d3165d8 dt: bindings: net: use boolean dt properties for eee broken modes
The patches regarding eee-broken-modes was merged before all people
involved could find an agreement on the best way to move forward.

While we agreed on having a DT property to mark particular modes as broken,
the value used for eee-broken-modes mapped the phy register in very direct
way. Because of this, the concern is that it could be used to implement
configuration policies instead of describing a broken HW.

In the end, having a boolean property for each mode seems to be preferred
over one bit field value mapping the register (too) directly.
