cpufreq: intel_pstate: Correct the busy calculation for KNL
They really are, and the "take the address of a single character" makes
the string fortification code unhappy (it believes that you can now only
acccess one byte, rather than a byte range, and then raises errors for
the memory copies going on in there).
We could now remove a few 'addressof' operators (since arrays naturally
degrade to pointers), but this is the minimal patch that just changes
the C prototypes of those template arrays (the templates themselves are
defined in inline asm).

Currently llist_for_each_entry() and llist_for_each_entry_safe() iterate
until &pos->member != NULL. But when building the kernel with Clang,
the compiler assumes &pos->member cannot be NULL if the member's offset
is greater than 0 (which would be equivalent to the object being
non-contiguous in memory). Therefore the loop condition is always true,
and the loops become infinite.
To work around this, introduce the member_address_is_nonnull() macro,
which casts object pointer to uintptr_t, thus letting the member pointer
to be NULL.

If the genpd->attach_dev or genpd->power_on fails, genpd_dev_pm_attach
may return -EPROBE_DEFER initially. However genpd_alloc_dev_data sets
the PM domain for the device unconditionally.
When subsequent attempts are made to call genpd_dev_pm_attach, it may
return -EEXISTS checking dev->pm_domain without re-attempting to call
attach_dev or power_on.
platform_drv_probe then attempts to call drv->probe as the return value
-EEXIST != -EPROBE_DEFER, which may end up in a situation where the
device is accessed without it's power domain switched on.

nfsd: Fix a memory scribble in the callback channel
When new directory 'DIR1' is created in a directory 'DIR0' with SGID bit
set, DIR1 is expected to have SGID bit set (and owning group equal to
the owning group of 'DIR0'). However when 'DIR0' also has some default
ACLs that 'DIR1' inherits, setting these ACLs will result in SGID bit on
'DIR1' to get cleared if user is not member of the owning group.
Fix the problem by creating __hfsplus_set_posix_acl() function that does
not call posix_acl_update_mode() and use it when inheriting ACLs. That
prevents SGID bit clearing and the mode has been properly set by
posix_acl_create() anyway.

According to ECMA-130 standard maximum valid track number is 99. Since
'session' mount option starts indexing at 0 (and we add 1 to the passed
number), we should refuse value 99. Also the condition in
isofs_get_last_session() unnecessarily repeats the check - remove it.

When changing a file's acl mask, reiserfs_set_acl() will first set the
group bits of i_mode to the value of the mask, and only then set the
actual extended attribute representing the new acl.
If the second part fails (due to lack of space, for example) and the
file had no acl attribute to begin with, the system will from now on
assume that the mask permission bits are actual group permission bits,
potentially granting access to the wrong users.
Prevent this by only changing the inode mode after the acl has been set.

When changing a file's acl mask, ext2_set_acl() will first set the group
bits of i_mode to the value of the mask, and only then set the actual
extended attribute representing the new acl.
If the second part fails (due to lack of space, for example) and the file
had no acl attribute to begin with, the system will from now on assume
that the mask permission bits are actual group permission bits, potentially
granting access to the wrong users.
Prevent this by only changing the inode mode after the acl has been set.

Playing with IP-O-IB interface can trigger a warning message:
"ib0: Failed to modify QP to ERROR state" to be logged.
This happens when the QP is in IB_QPS_RESET state and the stack
is trying to transition it to IB_QPS_ERR state in ipoib_ib_dev_stop().
According to the IB spec, Table 91 - "QP State Transition Properties"
it looks like the transition from reset to error is valid:
Transition: Any State to Error
Required Attributes: None
Optional Attributes: None allowed
Actions: Queue processing is stopped. Work Requests pending or in
process are completed in error, when possible.
This patch allows the transition and quiets the message.

In hip06 SoC, RoCE driver creates 8 reserved loopback QPs to

In order to solve this problem, the number of loopback Qps

Currently the RoCE GID management uses the ib_wq to do add and delete new GIDs
according to the netdev events.
The ib_wq isn't an ordered workqueue and thus two work elements can be executed
concurrently which will result in unexpected behavior and inconsistency of the
GIDs cache content.
Example:
ifconfig eth1 11.11.11.11/16 up
This command will invoke the following netdev events in the following order:
1. NETDEV_UP
2. NETDEV_DOWN
3. NETDEV_UP
If (2) and (3) will be executed concurrently or in reverse order, instead of
having a new GID with 11.11.11.11 IP, we will end up without any new GIDs.

Commit 21caf2fc19 ("mm: teach mm by current context info to not do I/O
during memory allocation") added the memalloc_noio_(save|restore) functions
to enable people to modify the MM behavior by disabling I/O during memory
allocation. This was further extended in Fixes: 934f3072c1 ("mm: clear
__GFP_FS when PF_MEMALLOC_NOIO is set"). memalloc_noio_* functions prevent
allocation paths recursing back into the filesystem without explicitly
changing the flags for every allocation site.
However the IPoIB hasn't been keeping up with the changes and missed
completely these memalloc_noio_* calls. This led to update of
allocation site with special QP creation flag, see commit 09b93088d7
("IB: Add a QP creation flag to use GFP_NOIO allocations"), while this
flag is supported by small number of drivers in IB stack.
Let's change it by updating to memalloc_noio_* calls and allow
for every driver underneath enjoy NOIO allocations.

nfit_init() calls nfit_mce_register() on module load. When the module
load fails the nfit mce decoder is not unregistered. The module's
memory is freed leaving the decoder chain referencing junk. This will
cause panics as future registrations will reference the free'd memory.
Unregister the nfit mce decoder on module init failure.
[v2]: register and then unregister mce handler to avoid losing mce events
[v3]: also cleanup nfit workqueue
