When using FITRIM ioctl on a file system without journal it will
only trim the block group once, no matter how many times you invoke
FITRIM ioctl and how many block you release from the block group.
It is because we only clear EXT4_GROUP_INFO_WAS_TRIMMED_BIT in journal
callback. Fix this by clearing the bit in no journal mode as well.

The GIC interrupt offsets are calculated based on the value of NR_CPUS.
However, this is wrong because NR_CPUS may or may not contain the real
number of the actual cpus present in the system. We fix that by using
the 'nr_cpu_ids' variable which contains the real number of cpus in
the system. Previously, an MT core (eg with 8 VPEs) will fail to boot if
NR_CPUS was > 8 with the following errors:

Commit 2dc4128 (ACPI / hotplug / PCI: Avoid doing too much for
spurious notifies) changed the enable_slot() to check return value of
pci_scan_slot() and if it is zero return early from the function. It
means that there were no new devices in this particular slot.
However, if a device appeared deeper in the hierarchy the code now
ignores it causing things like Thunderbolt chaining fail to recognize
new devices.
The problem with Alex Williamson's machine was solved with commit
a47d8c8 (ACPI / hotplug / PCI: Avoid parent bus rescans on spurious
device checks) and hence we should be able to restore the original
functionality that we always rescan on bus check notification.
On a device check notification we still check what acpiphp_rescan_slot()
returns and on zero bail out early.

This reverts commit 9745cdb36da8 (select: use freezable blocking call)
that triggers problems during resume from suspend to RAM on Paul Bolle's
32-bit x86 machines. Paul says:
Ever since I tried running (release candidates of) v3.11 on the two
working i686s I still have lying around I ran into issues on resuming
from suspend. Reverting 9745cdb36da8 (select: use freezable blocking
call) resolves those issues.
Resuming from suspend on i686 on (release candidates of) v3.11 and
later triggers issues like:
traps: systemd[1] general protection ip:b738e490 sp:bf882fc0 error:0 in libc-2.16.so[b731c000+1b0000]
and
traps: rtkit-daemon[552] general protection ip:804d6e5 sp:b6cb32f0 error:0 in rtkit-daemon[8048000+d000]
Once I hit the systemd error I can only get out of the mess that the
system is at that point by power cycling it.
Since we are reverting another freezer-related change causing similar
problems to happen, this one should be reverted as well.

We were using a different array of function pointers to represent each
minor version. This makes adding a new minor version tedious, since it
needs a step to copy, paste and modify a new version of the same
functions.
This patch combines the v4 and v4.1 arrays into a single instance and
will check minor version support inside each decoder function.

Most of the hid sensor field size is reported in report_size field
in the report descriptor. For rotation fusion sensor the quaternion
data is 16 byte field, the report size was set to 4 and report
count field is set to 4. So the total size is 16 bytes. But the current
driver has a bug and not taking account for report count field. This
causes user space to see only 4 bytes of data sent via IIO interface.
The number of bytes in a field needs to take account of report_count
field. Need to multiply report_size and report_count to get total
number of bytes.

The analog sticks of the pro-controller might report slightly off values.
To guarantee a uniform setup, we now calibrate analog-stick values during
pro-controller setup.
Unfortunately, the pro-controller fails during normal EEPROM reads and I
couldn't figure out whether there are any calibration values stored on the
device. Therefore, we now use the first values reported by the device (iff
they are not _way_ off, which would indicate movement) to initialize the
calibration values. To allow users to change this calibration data, we
provide a pro_calib sysfs attribute.
We also change the "flat" values so user-space correctly smoothes our
data. It makes slightly off zero-positions less visible while still
guaranteeing highly precise movement reports. Note that the pro controller
reports zero-positions in a quite huge range (at least: -100 to +100).

If a macro is only used within 2 times, and also its contents are
within 2 lines, recommend to expand it to shrink code line.
For our case, the macro is not portable either: some architectures'
assembler may use another character to mark newline in a macro (e.g.
'`' for arc), which will cause issue.
If still want to use macro and let it portable enough, it will also
need include additional header file (e.g "#include <linux/linkage.h>",
although it also need be fixed).

OF/DT core library provides architecture specific hook to match the
logical cpu index with the corresponding physical identifier.
On ARM64, the MPIDR_EL1 contains specific bitfields(MPIDR_EL1.Aff{3..0})
which uniquely identify a CPU, in addition to some non-identifying
information and reserved bits. The ARM cpu binding defines the 'reg'
property to only contain the affinity bits, and any cpu nodes with other
bits set in their 'reg' entry are skipped.
This patch overrides the weak definition of arch_match_cpu_phys_id
with ARM64 specific version using MPIDR_EL1.Aff{3..0} as cpu physical
identifiers.

In the common case, the ACPI_ALLOCATE and related macros now resolve
directly to their respective acpi_os* OSL interfaces. Two options:
1) The ACPI_ALLOCATE_ZEROED macro defaults to a simple local implementation
by default, unless overridden by the USE_NATIVE_ALLOCATE_ZEROED define.
2) For ACPI execution simulation environment (AcpiExec) which is not
shipped with the Linux kernel, the macros can optionally be resolved to
the local interfaces that track each allocation (used to immediately
detect memory leaks).

This change adds and deploys "safe" versions of strcpy and strcat that
ensure that the target buffer does not overflow. These safe functions
are only helpful for processing user input and command lines. For most
ACPICA code however, the required buffer length is precisely calculated
before buffer allocation, so the use of these functions is unnecessary.
ACPICA BZ 1043.
This change only applies to the ACPICA utilities and the debugger, none
of which are not shipped with the kernel yet, so the kernel's behavior

The original upstream ACPICA change added full history and limited
line editing to the debugger:
This change adds full history and limited line editing for Unix and
Linux systems. It does not use readline() because of portability issues.
Instead it uses the POSIX termio interface to put the terminal in raw
input mode so that the various special keys can be trapped (such as
up-arrow and down-arrow for history support).
Since the debugger is not shipped in the kernel, it only is necessary
to update one header file to keep the kernel source in sync with the
upstream.

If a key is displaced from a keyring by a matching one, then four more bytes
of quota are allocated to the keyring - despite the fact that the keyring does
not change in size.
Further, when a key is unlinked from a keyring, the four bytes of quota
allocated the link isn't recovered and returned to the user's pool.
The first can be tested by repeating:
keyctl add big_key a fred @s
cat /proc/key-users
(Don't put it in a shell loop otherwise the garbage collector won't have time
to clear the displaced keys, thus affecting the result).
This was causing the kerberos keyring to run out of room fairly quickly.
The second can be tested by:
cat /proc/key-users
a=`keyctl add user a a @s`
cat /proc/key-users
keyctl unlink $a
sleep 1 # Give RCU a chance to delete the key
cat /proc/key-users
assuming no system activity that otherwise adds/removes keys, the amount of
key data allocated should go up (say 40/20000 -> 47/20000) and then return to
the original value at the end.
