Without this we get lockdep failures. They're spurious failures as SMP isn't
up when ftrace_init_nop() is called. As far as I can tell the easiest fix is
to just take the lock, which also seems like the safest fix.

There may be many encrypted regions that need to be unregistered when a
SEV VM is destroyed. This can lead to soft lockups. For example, on a
host running 4.15:
watchdog: BUG: soft lockup - CPU#206 stuck for 11s! [t_virtual_machi:194348]
CPU: 206 PID: 194348 Comm: t_virtual_machi

[<0>] do_signal+0x31/0x130
Although the CLFLUSH is no longer issued on every encrypted region to be
unregistered, there are no other changes that can prevent soft lockups for
very large SEV VMs in the latest kernel.
Periodically schedule if necessary. This still holds kvm->lock across the
resched, but since this only happens when the VM is destroyed this is
assumed to be acceptable.

MIPS defines two kvm types:
#define KVM_VM_MIPS_TE 0
#define KVM_VM_MIPS_VZ 1
In Documentation/virt/kvm/api.rst it is said that "You probably want to
use 0 as machine type", which implies that type 0 be the "automatic" or
"default" type. And, in user-space libvirt use the null-machine (with
type 0) to detect the kvm capability, which returns "KVM not supported"
on a VZ platform.
I try to fix it in QEMU but it is ugly:
https://lists.nongnu.org/archive/html/qemu-devel/2020-08/msg05629.html
And Thomas Huth suggests me to change the definition of kvm type:
https://lists.nongnu.org/archive/html/qemu-devel/2020-09/msg03281.html
So I define like this:
#define KVM_VM_MIPS_AUTO 0
#define KVM_VM_MIPS_VZ 1
#define KVM_VM_MIPS_TE 2
Since VZ and TE cannot co-exists, using type 0 on a TE platform will
still return success (so old user-space tools have no problems on new
kernels); the advantage is that using type 0 on a VZ platform will not
return failure. So, the only problem is "new user-space tools use type
2 on old kernels", but if we treat this as a kernel bug, we can backport
this patch to old stable kernels.

When kvm_mmu_get_page() gets a page with unsynced children, the spt
pagetable is unsynchronized with the guest pagetable. But the
guest might not issue a "flush" operation on it when the pagetable
entry is changed from zero or other cases. The hypervisor has the
responsibility to synchronize the pagetables.
KVM behaved as above for many years, But commit 8c8560b83390
("KVM: x86/mmu: Use KVM_REQ_TLB_FLUSH_CURRENT for MMU specific flushes")
inadvertently included a line of code to change it without giving any
reason in the changelog. It is clear that the commit's intention was to
change KVM_REQ_TLB_FLUSH -> KVM_REQ_TLB_FLUSH_CURRENT, so we don't
needlessly flush other contexts; however, one of the hunks changed
a nearby KVM_REQ_MMU_SYNC instead. This patch changes it back.

When L2 uses PAE, L0 intercepts of L2 writes to CR0/CR3/CR4 call
load_pdptrs to read the possibly updated PDPTEs from the guest
physical address referenced by CR3. It loads them into
vcpu->arch.walk_mmu->pdptrs and sets VCPU_EXREG_PDPTR in
vcpu->arch.regs_dirty.
At the subsequent assumed reentry into L2, the mmu will call
vmx_load_mmu_pgd which calls ept_load_pdptrs. ept_load_pdptrs sees
VCPU_EXREG_PDPTR set in vcpu->arch.regs_dirty and loads
VMCS02.GUEST_PDPTRn from vcpu->arch.walk_mmu->pdptrs[]. This all works
if the L2 CRn write intercept always resumes L2.
The resume path calls vmx_check_nested_events which checks for
exceptions, MTF, and expired VMX preemption timers. If
vmx_check_nested_events finds any of these conditions pending it will
reflect the corresponding exit into L1. Live migration at this point
would also cause a missed immediate reentry into L2.
After L1 exits, vmx_vcpu_run calls vmx_register_cache_reset which
clears VCPU_EXREG_PDPTR in vcpu->arch.regs_dirty. When L2 next
resumes, ept_load_pdptrs finds VCPU_EXREG_PDPTR clear in
vcpu->arch.regs_dirty and does not load VMCS02.GUEST_PDPTRn from
vcpu->arch.walk_mmu->pdptrs[]. prepare_vmcs02 will then load
VMCS02.GUEST_PDPTRn from vmcs12->pdptr0/1/2/3 which contain the stale
values stored at last L2 exit. A repro of this bug showed L2 entering
triple fault immediately due to the bad VMCS02.GUEST_PDPTRn values.
When L2 is in PAE paging mode add a call to ept_load_pdptrs before
leaving L2. This will update VMCS02.GUEST_PDPTRn if they are dirty in
vcpu->arch.walk_mmu->pdptrs[].
Tested:
kvm-unit-tests with new directed test: vmx_mtf_pdpte_test.
Verified that test fails without the fix.
Also ran Google internal VMM with an Ubuntu 16.04 4.4.0-83 guest running a
custom hypervisor with a 32-bit Windows XP L2 guest using PAE. Prior to fix
would repro readily. Ran 14 simultaneous L2s for 140 iterations with no
failures.

Using gcov to collect coverage data for kernels compiled with GCC 10.1
causes random malfunctions and kernel crashes. This is the result of a
changed GCOV_COUNTERS value in GCC 10.1 that causes a mismatch between
the layout of the gcov_info structure created by GCC profiling code and
the related structure used by the kernel.
Fix this by updating the in-kernel GCOV_COUNTERS value. Also re-enable
config GCOV_KERNEL for use with GCC 10.

For new advertising features, it will be important for userspace to
know the capabilities of the controller and kernel. If the controller
and kernel support extended advertising, we include flags indicating
hardware offloading support and support for setting tx power of adv
instances.
In the future, vendor-specific commands may allow the setting of tx
power in advertising instances, but for now this feature is only
marked available if extended advertising is supported.
This change is manually verified in userspace by ensuring the
advertising manager's supported_flags field is updated with new flags on
hatch chromebook (ext advertising supported).

Here we make sure we properly report the number of supported
advertising slots when we are using hardware offloading. If no
hardware offloading is available, we default this value to
HCI_MAX_ADV_INSTANCES for use in software rotation as before.
This change has been tested on kukui (no ext adv) and hatch (ext adv)
chromebooks by verifying "SupportedInstances" shows 5 (the default) and
6 (slots supported by controller), respectively.

When HCI_QUIRK_NON_PERSISTENT_SETUP is set by drivers,
it indicates that BT SoC will be completely powered OFF
during BT OFF. On next BT ON firmware must be downloaded
again. Holding UART port open during BT OFF is draining
the battery. Now during BT OFF, UART port is closed if
qurik HCI_QUIRK_NON_PERSISTENT_SETUP is set by clearing
HCI_UART_PROTO_READY proto flag. On next BT ON, UART
port is opened if HCI_UART_PROTO_READY proto flag is cleared.

On new Intel platform the device is provided with INT33E3 ID.
Append it to the list.
This will require ACPI_GPIO_QUIRK_ONLY_GPIOIO to be enabled because
the relevant ASL looks like:
UartSerialBusV2 ( ... )
GpioInt ( ... ) { ... }
GpioIo ( ... ) { ... }
which means that first GPIO resource is an interrupt, while we are expecting it
to be reset one (output). Do the same for host-wake because in case of
GpioInt() the platform_get_irq() will do the job and should return correct
Linux IRQ number. That said, host-wake GPIO can only be GpioIo() resource.
While here, drop commas in terminator lines.

Neal Cardwell says:
====================
This patch series reorganizes TCP congestion control initialization so that if
EBPF code called by tcp_init_transfer() sets the congestion control algorithm
by calling setsockopt(TCP_CONGESTION) then the TCP stack initializes the
congestion control module immediately, instead of having tcp_init_transfer()
later initialize the congestion control module.
This increases flexibility for the EBPF code that runs at connection
establishment time, and simplifies the code.
This has the following benefits:
(1) This allows CC module customizations made by the EBPF called in
tcp_init_transfer() to persist, and not be wiped out by a later
call to tcp_init_congestion_control() in tcp_init_transfer().
(2) Does not flip the order of EBPF and CC init, to avoid causing bugs
for existing code upstream that depends on the current order.
(3) Does not cause 2 initializations for for CC in the case where the
EBPF called in tcp_init_transfer() wants to set the CC to a new CC
algorithm.
(4) Allows follow-on simplifications to the code in net/core/filter.c
and net/ipv4/tcp_cong.c, which currently both have some complexity
to special-case CC initialization to avoid double CC
initialization if EBPF sets the CC.
changes in v2:
o rebase onto bpf-next
o add another follow-on simplification suggested by Martin KaFai Lau:
"tcp: simplify tcp_set_congestion_control() load=false case"
changes in v3:
o no change in commits
o resent patch series from @gmail.com, since mail from ncardwell@google.com
stopped being accepted at netdev@vger.kernel.org mid-way through processing
the v2 patch series (between patches 2 and 3), confusing patchwork about
which patches belonged to the v2 patch series

Simplify tcp_set_congestion_control() by removing the initialization
code path for the !load case.
There are only two call sites for tcp_set_congestion_control(). The
EBPF call site is the only one that passes load=false; it also passes
cap_net_admin=true. Because of that, the exact same behavior can be
achieved by removing the special if (!load) branch of the logic. Both
before and after this commit, the EBPF case will call
bpf_try_module_get(), and if that succeeds then call
tcp_reinit_congestion_control() or if that fails then return EBUSY.
Note that this returns the logic to a structure very similar to the
structure before:
commit 91b5b21c7c16 ("bpf: Add support for changing congestion control")
except that the CAP_NET_ADMIN status is passed in as a function
argument.
This clean-up was suggested by Martin KaFai Lau.

Now that the previous patch ensures we don't initialize the congestion
control twice, when EBPF sets the congestion control algorithm at
connection establishment we can simplify the code by simply
initializing the congestion control module at that time.
