net: filter: misc/various cleanups
This contains only some minor misc cleanpus. We can spare us the
extra variable declaration in __skb_get_pay_offset(), the cast in
__get_random_u32() is rather unnecessary and in __sk_migrate_realloc()
we can remove the memcpy() and do a direct assignment of the structs.
Latter was suggested by Fengguang Wu found with coccinelle. Also,
remaining pointer casts of long should be unsigned long instead.

net: filter: make register naming more comprehensible
The current code is a bit hard to parse on which registers can be used,
how they are mapped and all play together. It makes much more sense to
define this a bit more clearly so that the code is a bit more intuitive.
This patch cleans this up, and makes naming a bit more consistent among
the code. This also allows for moving some of the defines into the header
file. Clearing of A and X registers in __sk_run_filter() do not get a
particular register name assigned as they have not an 'official' function,
but rather just result from the concrete initial mapping of old BPF
programs. Since for BPF helper functions for BPF_CALL we already use
small letters, so be consistent here as well. No functional changes.

net: filter: simplify label names from jump-table
This patch simplifies label naming for the BPF jump-table.
When we define labels via DL(), we just concatenate/textify
the combination of instruction opcode which consists of the
class, subclass, word size, target register and so on. Each
time we leave BPF_ prefix intact, so that e.g. the preprocessor
generates a label BPF_ALU_BPF_ADD_BPF_X for DL(BPF_ALU, BPF_ADD,
BPF_X) whereas a label name of ALU_ADD_X is much more easy
to grasp. Pure cleanup only.

ata: ahci_mvebu: new driver for Marvell Armada 380 AHCI interfaces
The Marvell Armada 380 SoC includes two AHCI compatible
interfaces. However, like all DMA-capable Marvell interface, they
require special handling to configure MBus windows. Therefore, this
commit adds a new ahci_mvebu driver, which relies on the
libahci_platform.c code recently introduced.

cgroup, memcg: implement css->id and convert css_from_id() to use it
Until now, cgroup->id has been used to identify all the associated
csses and css_from_id() takes cgroup ID and returns the matching css
by looking up the cgroup and then dereferencing the css associated
with it; however, now that the lifetimes of cgroup and css are
separate, this is incorrect and breaks on the unified hierarchy when a
controller is disabled and enabled back again before the previous
instance is released.
This patch adds css->id which is a subsystem-unique ID and converts
css_from_id() to look up by the new css->id instead. memcg is the
only user of css_from_id() and also converted to use css->id instead.
For traditional hierarchies, this shouldn't make any functional
difference.

cgroup: update init_css() into init_and_link_css()
init_css() takes the cgroup the new css belongs to as an argument and
initializes the new css's ->cgroup and ->parent pointers but doesn't
acquire the matching reference counts. After the previous patch,
create_css() puts init_css() and reference acquisition right next to
each other. Let's move reference acquistion into init_css() and
rename the function to init_and_link_css(). This makes sense and is
easier to follow. This makes the root csses to hold a reference on
cgrp_dfl_root.cgrp, which is harmless.

cgroup: use RCU free in create_css() failure path
Currently, when create_css() fails in the middle, the half-initialized
css is freed by invoking cgroup_subsys->css_free() directly. This
patch updates the function so that it invokes RCU free path instead.
As the RCU free path puts the parent css and owning cgroup, their
references are now acquired right after a new css is successfully
allocated.
This doesn't make any visible difference now but is to enable
implementing css->id and RCU protected lookup by such IDs.

cgroup: protect cgroup_root->cgroup_idr with a spinlock
Currently, cgroup_root->cgroup_idr is protected by cgroup_mutex, which
ends up requiring cgroup_put() to be invoked under sleepable context.
This is okay for now but is an unusual requirement and we'll soon add
css->id which will have the same problem but won't be able to simply
grab cgroup_mutex as removal will have to happen from css_release()
which can't sleep.
Introduce cgroup_idr_lock and idr_alloc/replace/remove() wrappers
which protects the idr operations with the lock and use them for
cgroup_root->cgroup_idr. cgroup_put() no longer needs to grab
cgroup_mutex and css_from_id() is updated to always require RCU read
lock instead of either RCU read lock or cgroup_mutex, which doesn't
affect the existing users.

cgroup, memcg: allocate cgroup ID from 1
Currently, cgroup->id is allocated from 0, which is always assigned to
the root cgroup; unfortunately, memcg wants to use ID 0 to indicate
invalid IDs and ends up incrementing all IDs by one.
It's reasonable to reserve 0 for special purposes. This patch updates
cgroup core so that ID 0 is not used and the root cgroups get ID 1.
The ID incrementing is removed form memcg.

cgroup: make flags and subsys_masks unsigned int
There's no reason to use atomic bitops for cgroup_subsys_state->flags,
cgroup_root->flags and various subsys_masks. This patch updates those
to use bitwise and/or operations instead and converts them form
unsigned long to unsigned int.
This makes the fields occupy (marginally) smaller space and makes it
clear that they don't require atomicity.
This patch doesn't cause any behavior difference.

It's caused by a silicon issue that SATA phy does not get reset by
controller when coming back from LPM. The patch adds a software
workaround for this issue. It enforces a software reset on SATA phy
in imx_sata_enable() function, so that we can ensure SATA link will
come up properly in both power-on and resume.
The software reset is implemented by writing phy reset register through
the phy control register bus interface. Functions
imx_phy_reg_[addressing|write|read]() implement this bus interface, while
imx_sata_phy_reset() performs the actually reset operation.

This function returns a bool, that is supposed to be false when something
goes wrong. It's assumed this way by its lone calling function (which is
SetRFPowerState8190(), line 1445 of rtl8192e/rtl8192e/r8192E_phy.c)
Despite of this, this procedure returns non-null enumerations values or

staging: comedi: drivers: correct mode check for i8254_set_mode()
The upper bound check on the `mode` parameter of `i8254_set_mode()` and
`i8254_mm_set_mode()` is incorrect. The `mode` parameter value consists
of a mode number in the range 0 to 5 in bits 3..1 {represented by the
constants `I8254_MODE0` (0 << 1) through to `I8254_MODE5` (2 << 1)} ORed
with a BCD/binary flag in bit 0 {represented by the constants
`I8254_BINARY` (0) and `I8254_BCD` (1)}. The maximum allowed value
ought to be `I8254_MODE5 | I8254_BCD` ((5 << 1) | 1), but is currently
`I8254_MODE5 | I8254_BINARY` ((5 << 1) | 0). Fix it.
None of the comedi drivers use `I8254_BCD` but some of the low-level
drivers allow user-space to configure the counter mode, so all legal
values ought to be allowed. However, it's pretty unlikely anyone would
want to set the counters to count in BCD (binary coded decimal) so the
bug is not that significant.

The calls to labpc_counter_load() will not fail so change the

staging: comedi: addi_common.h: remove 'ui_AiScanLength' from private data
This member of the private data is a copy of the cmd->scan_end_arg. Use that

Use a local variable in apci3120_cyclic_ai() for the DMA 'scan_bytes', which
is the cmd->scan_end_arg * 2. Replace the open-coded '2' with sizeof(short).
