The device-managed allocation API doesn't work well with the life-cycle
of device objects. Since ports have device objects allocated within, it
can lead to situations where these devices need to stay around until
after their parent pad controller has been unbound from its driver. The
device-managed memory allocated for the port objects will, however, get
freed when the pad controller unbinds from the driver. This can cause
use-after-free errors down the road.
Note that the device is deleted as part of the driver unbind operation,
so there isn't much that can be done with it after that point, but the
memory still needs to stay around to ensure none of the references are
invalidated.
One situation where this arises is when a VBUS supply is associated with
a USB 2 or 3 port. When that supply is released using regulator_put() an
SRCU call will queue the release of the device link connecting the port
and the regulator after a grace period. This means that the regulator is
going to keep on to the last reference of the port device even after the
pad controller driver was unbound (which is when the memory backing the
port device is freed).
Fix this by allocating port objects using non-device-managed memory. Add
release callbacks for these objects so that their memory gets freed when
the last reference goes away. This decouples the port devices' lifetime
from the "active" lifetime of the pad controller (i.e. the time during
which the pad controller driver owns the device).
Signed-off-by: Thierry Reding <treding@nvidia.com>
Devices are created for each port of the XUSB pad controller. Each USB 2
and USB 3 port can potentially have an associated VBUS power supply that
needs to be removed when the device is removed.
Since port devices never bind to a driver, the driver core will not get
to perform the cleanup of device-managed resources that usually happens
on driver unbind.
Now, the driver core will also perform device-managed resource cleanup
for driver-less devices when they are released. However, when a device
link is created between the regulator and the port device, as part of
regulator_get(), the regulator takes a reference to the port device and
prevents it from being released unless regulator_put() is called, which
will never happen.
Avoid this by using the non-device-managed API and manually releasing
the regulator reference when the port is unregistered.

Add support for the XUSB pad controller found on Tegra194 SoCs. It is
mostly similar to the same IP found on Tegra186, but the number of
pads exposed differs, as do the programming sequences. Because most of
the Tegra194 XUSB PADCTL registers definition and programming sequence
are the same as Tegra186, Tegra194 XUSB PADCTL can share the same
driver, xusb-tegra186.c, with Tegra186 XUSB PADCTL.
Tegra194 XUSB PADCTL supports up to USB 3.1 Gen 2 speed, however, it
is possible for some platforms have long signal trace that could not
provide sufficient electrical environment for Gen 2 speed. This patch
adds a "maximum-speed" property to usb3 ports which can be used to
specify the maximum supported speed for any particular USB 3.1 port.
For a port that is not capable of SuperSpeedPlus, "maximum-speed"
property should carry "super-speed".

Some userland application/program runtime/dynamic loaded need to
know about the current ISA level to use the best runtime.
While kernel doesn't provides this info.
ELF_PLATFORM only provides some info about the CPU, with very few info,
for example, the value is "mips" for both 24Kc and P6600.
Currently ELF_BASE_PLATFORM is not used by MIPS (only by powerpc).
So we cant set its value as:
mips2, mips3, mips4, mips5,
mips32, mips32r2, mips32r6
mips64, mips64r2, mips64r6
Then in userland, we can get it by:
getauxval(AT_BASE_PLATFORM)
The only problem is that it seems has different defination than ppc:
on ppc, it is the mircoarchitecture
while now we use it as ISA level on MIPS.

Simplify gen_btf logic to make it work with llvm-objcopy. The existing
'file format' and 'architecture' parsing logic is brittle and does not
work with llvm-objcopy/llvm-objdump.
'file format' output of llvm-objdump>=11 will match GNU objdump, but
'architecture' (bfdarch) may not.
.BTF in .tmp_vmlinux.btf is non-SHF_ALLOC. Add the SHF_ALLOC flag
because it is part of vmlinux image used for introspection. C code
can reference the section via linker script defined __start_BTF and
__stop_BTF. This fixes a small problem that previous .BTF had the
SHF_WRITE flag (objcopy -I binary -O elf* synthesized .data).
Additionally, `objcopy -I binary` synthesized symbols
_binary__btf_vmlinux_bin_start and _binary__btf_vmlinux_bin_stop (not
used elsewhere) are replaced with more commonplace __start_BTF and
__stop_BTF.
Add 2>/dev/null because GNU objcopy (but not llvm-objcopy) warns
"empty loadable segment detected at vaddr=0xffffffff81000000, is this intentional?"
We use a dd command to change the e_type field in the ELF header from
ET_EXEC to ET_REL so that lld will accept .btf.vmlinux.bin.o. Accepting
ET_EXEC as an input file is an extremely rare GNU ld feature that lld
does not intend to support, because this is error-prone.
The output section description .BTF in include/asm-generic/vmlinux.lds.h
avoids potential subtle orphan section placement issues and suppresses
--orphan-handling=warn warnings.

Before GICv4.1, all operations would be serialized with the affinity
changes by virtue of using the same ITS command queue. With v4.1, things
change, as invalidations (and a number of other operations) are issued
using the redistributor MMIO frame.
We must thus make sure that these redistributor accesses cannot race
against aginst the affinity change, or we may end-up talking to the
wrong redistributor.
To ensure this, we expand the irq_to_cpuid() helper to take a spinlock
when the LPI is mapped to a vLPI (a new per-VPE lock) on each operation
that requires mutual exclusion.

To allow the direct injection of SGIs into a guest, the GICv4.1
architecture has to sacrifice the Active state so that SGIs look
a lot like LPIs (they are injected by the same mechanism).
In order not to break existing software, the architecture gives
offers guests OSs the choice: SGIs with or without an active
state. It is the hypervisors duty to honor the guest's choice.
For this, the architecture offers a discovery bit indicating whether
the GIC supports GICv4.1 SGIs (GICD_TYPER2.nASSGIcap), and another
bit indicating whether the guest wants Active-less SGIs or not
(controlled by GICD_CTLR.nASSGIreq).
A hypervisor not supporting GICv4.1 SGIs would leave nASSGIcap
clear, and a guest not knowing about GICv4.1 SGIs (or definitely
wanting an Active state) would leave nASSGIreq clear (both being
thankfully backward compatible with older revisions of the GIC).
Since Linux is perfectly happy without an active state on SGIs,
inform the hypervisor that we'll use that if offered.

When booting x86 images in qemu, the following warning is seen randomly
if DEBUG_LOCKDEP is enabled.
WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:1119
lockdep_register_key+0xc0/0x100
static_obj() returns true if an address is between _stext and _end.
On x86, this includes the brk memory space. Problem is that this memory
block is not static on x86; its unused portions are released after init
and can be allocated. This results in the observed warning if a lockdep
object is allocated from this memory.
Solve the problem by implementing arch_is_kernel_initmem_freed() for
x86 and have it return true if an address is within the released memory
range.
The same problem was solved for s390 with commit
7a5da02de8 ("locking/lockdep: check for freed initmem in static_obj()"),
which introduced arch_is_kernel_initmem_freed().

request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.
Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.
Hence replace setup_irq() by request_irq().

To minimize latency, PREEMPT_RT kernels expires hrtimers in preemptible
softirq context by default. This can be overriden by marking the timer's
expiry with HRTIMER_MODE_HARD.
sched_clock_timer is missing this annotation: if its callback is preempted
and the duration of the preemption exceeds the wrap around time of the
underlying clocksource, sched clock will get out of sync.
Mark the sched_clock_timer for expiry in hard interrupt context.

Enclose the chained handler with chained_irq_{enter,exit}(), so that the
muxed interrupts get properly acked.
This patch also fixes a reboot bug on OX820 SoC, where the jiffies timer
interrupt is never acked. The kernel waits a clock tick forever in
calibrate_delay_converge(), which leads to a boot hang.
