As reported in STAR 9001165532, an SLC control reg read (for checking
busy state) right after SLC invalidate command may incorrectly return
NOT busy causing software to NOT spin-wait while operation is underway.
(and for some reason this only happens if L1 cache is also disabled - as
required by IOC programming model)
Suggested workaround is to do an additional Control Reg read, which
ensures the 2nd read gets the right status.

ASoC: Fixes for v4.11
A relatively large pile of fixes for mainline, the first since the merge
window. The biggest block of changes here by volume is the sun8i-codec
set, the driver was newly added in the merge window but it was realized
that renaming some of the user visible controls was required so these
are being pushed for v4.11 to avoid the original code appearing in a
release. Otherwise it's all fairly standard bugfix stuff.
Commit 5c492c3f52 ("arm64: smp: Add function to determine if cpus are
stuck in the kernel") added a helper function to determine if die() is
supported in cpu_ops. This function assumes a cpu will have a valid
cpu_ops entry, but that may not be the case for cpu0 is spin-table or
parking protocol is used to boot secondary cpus. In that case, there
is a NULL dereference if have_cpu_die() is called by cpu0. So add a
check for a valid cpu_ops before dereferencing it.

Merge PTRACE_SETREGSET leakage fixes from Dave Martin:
"This series is the collection of fixes I proposed on this topic, that
have not yet appeared upstream or in the stable branches,
The issue can leak kernel stack, but doesn't appear to allow userspace
to attack the kernel directly. The affected architectures are c6x,
h8300, metag, mips and sparc.
[ Mark Salter points out that c6x has no MMU or other mechanism to
prevent userspace access to kernel code or data on c6x, but it
doesn't hurt to clean that case up too. ]
The bugs arise from use of user_regset_copyin(). Users of
user_regset_copyin() can work in one of two ways:
1) Copy directly to thread_struct or equivalent. (This seems to be
the design assumption of the regset API, and is the most common
approach.)
2) Copy to a local variable and then transfer to thread_struct. (A
significant minority of cases.)
Buggy code typically involves approach 2"

sparc/ptrace: Preserve previous registers for short regset write

regs_set() and regs_get() are vulnerable to an off-by-1 buffer overrun
if CONFIG_CPU_H8S is set, since this adds an extra entry to
register_offset[] but not to user_regs_struct.
So, iterate over user_regs_struct based on its actual size, not based on
the length of register_offset[].

gpr_set won't work correctly and can never have been tested, and the

The nested_ept_enabled flag introduced in commit 7ca29de213 was not
computed correctly. We are interested only in L1's EPT state, not the
the combined L0+L1 value.
In particular, if L0 uses EPT but L1 does not, nested_ept_enabled must
be false to make sure that PDPSTRs are loaded based on CR3 as usual,
because the special case described in 26.3.2.4 Loading Page-Directory-
Pointer-Table Entries does not apply.

Reference SDM 30.3 INVVPID:
Protected Mode Exceptions
- #UD
- If not in VMX operation.
- If the logical processor does not support VPIDs (IA32_VMX_PROCBASED_CTLS2[37]=0).
- If the logical processor supports VPIDs (IA32_VMX_PROCBASED_CTLS2[37]=1) but does
not support the INVVPID instruction (IA32_VMX_EPT_VPID_CAP[32]=0).
So we should check both VPID enable bit in vmx exec control and INVVPID support bit
in vmx capability MSRs to enable VPID. This patch adds the guarantee to not enable
VPID if either INVVPID or single-context/all-context invalidation is not exposed in
vmx capability MSRs.

We should hide and forbid VPID in L1 if it is disabled on L0. However, nested VPID
enable bit is set unconditionally during setup nested vmx exec controls though VPID
is not exposed through nested VMX capablity. This patch fixes it by don't set nested

After async pf setup successfully, there is a broadcast wakeup w/ special
token 0xffffffff which tells vCPU that it should wake up all processes
waiting for APFs though there is no real process waiting at the moment.
The async page present tracepoint print prematurely and fails to catch the
special token setup. This patch fixes it by moving the async page present
tracepoint after the special token setup.

Quoting from the Intel SDM, volume 3, section 28.3.3.4: Guidelines for
Use of the INVEPT Instruction:
If EPT was in use on a logical processor at one time with EPTP X, it
is recommended that software use the INVEPT instruction with the
"single-context" INVEPT type and with EPTP X in the INVEPT descriptor
before a VM entry on the same logical processor that enables EPT with
EPTP X and either (a) the "virtualize APIC accesses" VM-execution
control was changed from 0 to 1; or (b) the value of the APIC-access
address was changed.
In the nested case, the burden falls on L1, unless L0 enables EPT in
vmcs02 when L1 doesn't enable EPT in vmcs12.

If kernel image extends across alignment boundary, existing
code increases the KASLR offset by size of kernel image. The
offset is masked after resizing. There are cases, where after
masking, we may still have kernel image extending across
boundary. This eventually results in only 2MB block getting
mapped while creating the page tables. This results in data aborts
while accessing unmapped regions during second relocation (with
kaslr offset) in __primary_switch. To fix this problem, round up the
kernel image size, by swapper block size, before adding it for
correction.
For example consider below case, where kernel image still crosses
1GB alignment boundary, after masking the offset, which is fixed
by rounding up kernel image size.
SWAPPER_TABLE_SHIFT = 30
Swapper using section maps with section size 2MB.
CONFIG_PGTABLE_LEVELS = 3
VA_BITS = 39
_text : 0xffffff8008080000
_end : 0xffffff800aa1b000
offset : 0x1f35600000
mask = ((1UL << (VA_BITS - 2)) - 1) & ~(SZ_2M - 1)
(_text + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7c
(_end + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d
offset after existing correction (before mask) = 0x1f37f9b000
(_text + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d
(_end + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d
offset (after mask) = 0x1f37e00000
(_text + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7c
(_end + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d
new offset w/ rounding up = 0x1f38000000
(_text + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d

Now that we do have the machinery for using the radix MMU under a

no longer correct. The result is that when booted under a hypervisor
that only allows use of radix, we clear the MMU_FTR_TYPE_RADIX and
then set it again, and print a warning about ignoring the
disable_radix command line option, even though the command line does
not include "disable_radix".

If avic is not enabled, avic_vm_init() does nothing and returns early.
However, avic_vm_destroy() still tries to destroy what hasn't been created.
The only bad consequence of this now is that avic_vm_destroy() uses
svm_vm_data_hash_lock that hasn't been initialized (and is not meant
to be used at all if avic is not enabled).
Return early from avic_vm_destroy() if avic is not enabled.
It has nothing to destroy.

We concluded there may be a window where the idle wakeup code could get
to pnv_wakeup_tb_loss() (which clobbers non-volatile GPRs), but the
hardware may set SRR1[46:47] to 01b (no state loss) which would result
in the wakeup code failing to restore non-volatile GPRs.
I was not able to trigger this condition with trivial tests on real
hardware or simulator, but the ISA (at least 2.07) seems to allow for
it, and Gautham says that it can happen if there is an exception pending
when the sleep/winkle instruction is executed.
