ASPEED defconfig updates for 4.19

 - Refresh the multi ARMv5 defconfig, and add AST2400 related drivers

 - Enable new ASPEED hardware that we've merged in the past few cycles.
 There are about 14 different drivers since we last refreshed the
 defconfig

 - Turn on features required by systemd, and other bits of OpenBMC
 userspace

d4da0e97ba MIPS: WARN_ON invalid DMA cache maintenance, not BUG_ON

The binding for the USB PHY went thru before the driver. However the

this expect the reset to be named "phy". So remove the "usb-" prefix

a0553e01f8 MIPS: mscc: ocelot: add MIIM1 bus
There is an additional MIIM (MDIO) bus in this SoC so let's declare it
in the dtsi.

This bus requires GPIO 14 and 15 pins that need to be muxed. There is no
support for internal PHY reset on this bus on the contrary of MIIM0 so
there is only one register address space and not two.

c32cd419d6 ARM: signal: copy registers using __copy_from_user()
__get_user_error() is used as a fast accessor to make copying structure
members in the signal handling path as efficient as possible.  However,
with software PAN and the recent Spectre variant 1, the efficiency is
reduced as these are no longer fast accessors.

In the case of software PAN, it has to switch the domain register around
each access, and with Spectre variant 1, it would have to repeat the
access_ok() check for each access.

It becomes much more efficient to use __copy_from_user() instead, so
let's use this for the ARM integer registers.

0b3e336601 arm64: Add support for STACKLEAK gcc plugin
This adds support for the STACKLEAK gcc plugin to arm64 by implementing
stackleak_check_alloca(), based heavily on the x86 version, and adding the
two helpers used by the stackleak common code: current_top_of_stack() and
on_thread_stack(). The stack erasure calls are made at syscall returns.
Additionally, this disables the plugin in hypervisor and EFI stub code,
which are out of scope for the protection.

c2cd0b08e1 x86/power/hibernate_64: Remove VLA usage
In the quest to remove all stack VLA usage from the kernel [1], this
removes the discouraged use of AHASH_REQUEST_ON_STACK by switching to
shash directly and allocating the descriptor in heap memory (which should
be fine: the tfm has already been allocated there too).

Start using ti-sysc with device tree data for omap4 l4 devices

With ti-sysc driver working for most use cases, we can start converting
the omap variant SoCs to use device tree data for the interconnect target
modules instead of the legacy hwmod platform data.

We start with omap4 l4 devices excluding the ones that still depend on
a reset controller driver like DSP MMU. And we don't yet convert the l4
ABE instance as that needs a bit more work.

We also add a proper interconnect hierarchy for the devices while at it
to make further work on genpd easier and to avoid most deferred probe
issues.

At this point we are not dropping any platform data, and we initially
still use it to validate the dts data. Then in later merge cycles we
can start dropping the related platform data.

b5c6f7607b KVM: PPC: Book3S HV: Read kvm->arch.emul_smt_mode under kvm->lock
Commit 1e175d2 ("KVM: PPC: Book3S HV: Pack VCORE IDs to access full
VCPU ID space", 2018-07-25) added code that uses kvm->arch.emul_smt_mode
before any VCPUs are created.  However, userspace can change
kvm->arch.emul_smt_mode at any time up until the first VCPU is created.
Hence it is (theoretically) possible for the check in
kvmppc_core_vcpu_create_hv() to race with another userspace thread
changing kvm->arch.emul_smt_mode.

This fixes it by moving the test that uses kvm->arch.emul_smt_mode into
the block where kvm->lock is held.

1ebe6b81eb KVM: PPC: Book3S HV: Allow creating max number of VCPUs on POWER9
Commit 1e175d2 ("KVM: PPC: Book3S HV: Pack VCORE IDs to access full
VCPU ID space", 2018-07-25) allowed use of VCPU IDs up to
KVM_MAX_VCPU_ID on POWER9 in all guest SMT modes and guest emulated
hardware SMT modes.  However, with the current definition of
KVM_MAX_VCPU_ID, a guest SMT mode of 1 and an emulated SMT mode of 8,
it is only possible to create KVM_MAX_VCPUS / 2 VCPUS, because
threads_per_subcore is 4 on POWER9 CPUs.  (Using an emulated SMT mode
of 8 is useful when migrating VMs to or from POWER8 hosts.)

This increases KVM_MAX_VCPU_ID to 8 * KVM_MAX_VCPUS when HV KVM is
configured in, so that a full complement of KVM_MAX_VCPUS VCPUs can
be created on POWER9 in all guest SMT modes and emulated hardware
SMT modes.

1e175d2e07 KVM: PPC: Book3S HV: Pack VCORE IDs to access full VCPU ID space
It is not currently possible to create the full number of possible
VCPUs (KVM_MAX_VCPUS) on Power9 with KVM-HV when the guest uses fewer
threads per core than its core stride (or "VSMT mode"). This is
because the VCORE ID and XIVE offsets grow beyond KVM_MAX_VCPUS
even though the VCPU ID is less than KVM_MAX_VCPU_ID.

To address this, "pack" the VCORE ID and XIVE offsets by using
knowledge of the way the VCPU IDs will be used when there are fewer
guest threads per core than the core stride. The primary thread of
each core will always be used first. Then, if the guest uses more than
one thread per core, these secondary threads will sequentially follow
the primary in each core.

So, the only way an ID above KVM_MAX_VCPUS can be seen, is if the
VCPUs are being spaced apart, so at least half of each core is empty,
and IDs between KVM_MAX_VCPUS and (KVM_MAX_VCPUS * 2) can be mapped
into the second half of each core (4..7, in an 8-thread core).

Similarly, if IDs above KVM_MAX_VCPUS * 2 are seen, at least 3/4 of
each core is being left empty, and we can map down into the second and
third quarters of each core (2, 3 and 5, 6 in an 8-thread core).

Lastly, if IDs above KVM_MAX_VCPUS * 4 are seen, only the primary
threads are being used and 7/8 of the core is empty, allowing use of
the 1, 5, 3 and 7 thread slots.

(Strides less than 8 are handled similarly.)

This allows the VCORE ID or offset to be calculated quickly from the
VCPU ID or XIVE server numbers, without access to the VCPU structure.

[paulus@ozlabs.org - tidied up comment a little, changed some WARN_ONCE
 to pr_devel, wrapped line, fixed id check.]

7b0eb6b41a arm64: fix vmemmap BUILD_BUG_ON() triggering on !vmemmap setups
Arnd reports the following arm64 randconfig build error with the PSI
patches that add another page flag:

  /git/arm-soc/arch/arm64/mm/init.c: In function 'mem_init':
  /git/arm-soc/include/linux/compiler.h:357:38: error: call to
  '__compiletime_assert_618' declared with attribute error: BUILD_BUG_ON
  failed: sizeof(struct page) > (1 << STRUCT_PAGE_MAX_SHIFT)

The additional page flag causes other information stored in
page->flags to get bumped into their own struct page member:

  #if SECTIONS_WIDTH+ZONES_WIDTH+NODES_SHIFT+LAST_CPUPID_SHIFT <=
  BITS_PER_LONG - NR_PAGEFLAGS
  #define LAST_CPUPID_WIDTH LAST_CPUPID_SHIFT
  #else
  #define LAST_CPUPID_WIDTH 0
  #endif

  #if defined(CONFIG_NUMA_BALANCING) && LAST_CPUPID_WIDTH == 0
  #define LAST_CPUPID_NOT_IN_PAGE_FLAGS
  #endif

which in turn causes the struct page size to exceed the size set in
STRUCT_PAGE_MAX_SHIFT. This value is an an estimate used to size the
VMEMMAP page array according to address space and struct page size.

However, the check is performed - and triggers here - on a !VMEMMAP
config, which consumes an additional 22 page bits for the sparse
section id. When VMEMMAP is enabled, those bits are returned, cpupid
doesn't need its own member, and the page passes the VMEMMAP check.

Restrict that check to the situation it was meant to check: that we
are sizing the VMEMMAP page array correctly.

Says Arnd:

    Further experiments show that the build error already existed before,
    but was only triggered with larger values of CONFIG_NR_CPU and/or
    CONFIG_NODES_SHIFT that might be used in actual configurations but
    not in randconfig builds.

    With longer CPU and node masks, I could recreate the problem with
    kernels as old as linux-4.7 when arm64 NUMA support got added.

Return to the orginal order of errata and feature evaluation to
ensure errata flags are present during feature evaluation.
