When dumping the paca in xmon we currently show kstack. Although it's
not hard it's a bit fiddly to work out what the bounds of the kernel
stack should be based on the kstack value.
To make life easier and "kstack_base" which is the base (lowest
address) of the kernel stack, eg:
kstack = 0xc0000000f1a7be30 (0x258)
kstack_base = 0xc0000000f1a78000

i2c-dev provides an interface for userspace programs to interact with I2C
devices, and is very helpful for I2C-related debugging.
Enable it in pseries_defconfig and powernv_defconfig. It's already enabled
in many other powerpc defconfigs.

We call these functions with non-NULL mm or vma. Hence we can skip the
NULL check in these functions. We also remove now unused function
__local_flush_hugetlb_page().

Currently xmon could call XIVE functions from OPAL even if the XIVE is
disabled or does not exist in the system, as in POWER8 machines. This
causes the following exception:
1:mon> dx
cpu 0x1: Vector: 700 (Program Check) at [c000000423c93450]
pc: c00000000009cfa4: opal_xive_dump+0x50/0x68
lr: c0000000000997b8: opal_return+0x0/0x50
This patch simply checks if XIVE is enabled before calling XIVE
functions.

The vdd10_lcd and vcc18_lcd regulators need to be enabled for HDMI output
to work, so add 'regulator-always-on', just as is done in rk3288-firefly.dtsi.

When a exception is trapped to EL2, hardware uses ELR_ELx to hold
the current fault instruction address. If KVM wants to inject a
abort to 32 bit guest, it needs to set the LR register for the
guest to emulate this abort happened in the guest. Because ARM32
architecture is pipelined execution, so the LR value has an offset to
the fault instruction address.
The offsets applied to Link value for exceptions as shown below,
which should be added for the ARM32 link register(LR).
Table taken from ARMv8 ARM DDI0487B-B, table G1-10:
Exception Offset, for PE state of:
A32 T32
Undefined Instruction +4 +2
Prefetch Abort +4 +4
Data Abort +8 +8

Unfortunately userspace can construct a sigcontext which enables
suspend. Thus userspace can force Linux into a path where trechkpt is
executed.
This patch blocks this from happening on POWER9 by sanity checking
sigcontexts passed in.
ptrace doesn't have this problem as only MSR SE and BE can be changed
via ptrace.
This patch also adds a number of WARN_ON()s in case we ever enter
suspend when we shouldn't. This should not happen, but if it does the
symptoms are soft lockup warnings which are not obviously TM related,
so the WARN_ON()s should make it obvious what's happening.

Some Power9 revisions can run in a mode where TM operates without
suspended state. If we find ourself on a CPU that might be in this
mode, we query OPAL to check, and if so we reenable TM in CPU
features, and enable a new user feature to signal to userspace that we
are in this mode.
We do not enable the "normal" user feature, PPC_FEATURE2_HTM, but we
do enable PPC_FEATURE2_HTM_NOSC because that indicates to userspace
that the kernel will abort transactions on syscall entry, which is
true regardless of the suspend mode.

Without the STDMAC clock enabled, the USB 2.0 hosts do not work.
This clock must be explicitly listed in the "clocks" property because

Both Intel SDM and AMD APM mentioned that MCi_STATUS, when the register is
implemented, this register can be cleared by explicitly writing 0s to this
register. Writing 1s to this register will cause a general-protection
exception.
The mce is emulated in qemu, so just the guest attempts to write 1 to this
register should cause a #GP, this patch does it.

In my setup, EPT is not exposed to L1, the VPID capability is exposed and
can be observed by vmxcap tool in L1:
INVVPID supported yes
Individual-address INVVPID yes
Single-context INVVPID yes
All-context INVVPID yes
Single-context-retaining-globals INVVPID yes
However, the module parameter of VPID observed in L1 is always N, the
cpu_has_vmx_invvpid() check in L1 KVM fails since vmx_capability.vpid
is 0 and it is not read from MSR due to EPT is not exposed.
The VPID can be used to tag linear mappings when EPT is not enabled. However,
current logic just detects VPID capability if EPT is enabled, this patch
fixes it.

I can use vmxcap tool to observe "EPTP Switching yes" even if EPT is not
exposed to L1.
EPT switching is advertised unconditionally since it is emulated, however,
it can be treated as an extended feature for EPT and it should not be
advertised if EPT itself is not exposed. This patch fixes it.

We are going to support boot-time switching between 4- and 5-level
paging. For KASAN it means we cannot have different KASAN_SHADOW_OFFSET
for different paging modes: the constant is passed to gcc to generate
code and cannot be changed at runtime.
This patch changes KASAN code to use 0xdffffc0000000000 as shadow offset
for both 4- and 5-level paging.
For 5-level paging it means that shadow memory region is not aligned to
PGD boundary anymore and we have to handle unaligned parts of the region
properly.
In addition, we have to exclude paravirt code from KASAN instrumentation
as we now use set_pgd() before KASAN is fully ready.

We do not have tracepoints for sys_modify_ldt() because we define
it directly instead of using the normal SYSCALL_DEFINEx() macros.
However, there is a reason sys_modify_ldt() does not use the macros:
it has an 'int' return type instead of 'unsigned long'. This is
a bug, but it's a bug cemented in the ABI.
What does this mean? If we return -EINVAL from a function that
returns 'int', we have 0x00000000ffffffea in %rax. But, if we
return -EINVAL from a function returning 'unsigned long', we end
up with 0xffffffffffffffea in %rax, which is wrong.
To work around this and maintain the 'int' behavior while using
the SYSCALL_DEFINEx() macros, so we add a cast to 'unsigned int'
in both implementations of sys_modify_ldt().

Currently, it is possible to mmap() any offset from /dev/mem. If a
program mmaps() /dev/mem offsets outside of the addressable limits
of a system, the page table can be corrupted by setting reserved bits.
For example if you mmap() offset 0x0001000000000000 of /dev/mem on an
x86_64 system with a 48-bit bus, the page fault handler will be called
with error_code set to RSVD. The kernel then crashes with a page table
corruption error.
This change prevents this page table corruption on x86 by refusing
to mmap offsets higher than the highest valid address in the system.

We want to wait for all potentially preempted kprobes trampoline
execution to have completed. This guarantees that any freed
trampoline memory is not in use by any task in the system anymore.
synchronize_rcu_tasks() gives such a guarantee, so use it.
Also, this guarantees to wait for all potentially preempted tasks
on the instructions which will be replaced with a jump.
Since this becomes a problem only when CONFIG_PREEMPT=y, enable
CONFIG_TASKS_RCU=y for synchronize_rcu_tasks() in that case.

Some CPUs can operate in a mode where TM (Transactional Memory) is
enabled but the suspended state of TM is disabled. In this mode
tsuspend does not enter suspended state, instead the transaction is
aborted. Similarly any other event that would lead to suspended state
instead aborts the transaction.
There is also an ABI change, in that in this mode processes are not
allowed to sigreturn with an MSR that would lead to suspended state,
Linux will instead return an error to the sigreturn syscall.

Currently the kernel relies on firmware to inform it whether or not the
CPU supports HTM and as long as the kernel was built with
CONFIG_PPC_TRANSACTIONAL_MEM=y then it will allow userspace to make
use of the facility.
There may be situations where it would be advantageous for the kernel
to not allow userspace to use HTM, currently the only way to achieve
this is to recompile the kernel with CONFIG_PPC_TRANSACTIONAL_MEM=n.
This patch adds a simple commandline option so that HTM can be
disabled at boot time.

Bring in some KVM commits we need (the TM one in particular).
|
|
Currently we use CPU_FTR_TM to decide if the CPU/kernel can support
TM (Transactional Memory), and if it's true we advertise that to
Qemu (or similar) via KVM_CAP_PPC_HTM.
PPC_FEATURE2_HTM is the user-visible feature bit, which indicates that
the CPU and kernel can support TM. Currently CPU_FTR_TM and
PPC_FEATURE2_HTM always have the same value, either true or false, so
using the former for KVM_CAP_PPC_HTM is correct.
However some Power9 CPUs can operate in a mode where TM is enabled but
TM suspended state is disabled. In this mode CPU_FTR_TM is true, but
PPC_FEATURE2_HTM is false. Instead a different PPC_FEATURE2 bit is
set, to indicate that this different mode of TM is available.
It is not safe to let guests use TM as-is, when the CPU is in this
mode. So to prevent that from happening, use PPC_FEATURE2_HTM to
determine the value of KVM_CAP_PPC_HTM.

interconnect target device driver to handle the new generic "ti,sysc"
compatible property. And then we can finally drop the legacy platform

Non-urgent device tree fixes for omaps that can all wait for v4.15
merge window.
Turns out that we have many devices working just because we have
the legacy platform data still around. This is mostly an issue
for omap4, other SoCs just have minimal fixes needed.
As many of the missing device tree nodes and properties are for
devices that have no drivers in the mainline kernel, such as
slimbus, iss, mcasp, aess, fdif and gpu, we might as well start
using the new "ti,sysc" interconnect target module binding for
them so we can get the devices with no child device drivers idled.
This also makes it possible to drop unnecessary platform data
in later patches.
