Pull arm64 fixes from Will Deacon:
"These are all very simple and self-contained, although the CFI
jump-table fix touches the generic linker script as that's where the
problematic macro lives.
- Fix false positive "sleeping while atomic" warning resulting from
the kPTI rework taking a mutex too early.
- Fix possible overflow in AMU frequency calculation
- Fix incorrect shift in CMN PMU driver which causes problems with
newer versions of the IP
- Reduce alignment of the CFI jump table to avoid huge kernel images
and link errors with !4KiB page size configurations"

Inject #UD when emulating XSETBV if CR4.OSXSAVE is not set. This also
covers the "XSAVE not supported" check, as setting CR4.OSXSAVE=1 #GPs if
XSAVE is not supported (and userspace gets to keep the pieces if it
forces incoherent vCPU state).
Add a comment to kvm_emulate_xsetbv() to call out that the CPU checks
CR4.OSXSAVE before checking for intercepts. AMD'S APM implies that #UD
has priority (says that intercepts are checked before #GP exceptions),
while Intel's SDM says nothing about interception priority. However,
testing on hardware shows that both AMD and Intel CPUs prioritize the #UD
over interception.

Allow FP and SSE state to be saved and restored via KVM_{G,SET}_XSAVE on
XSAVE-capable hosts even if their bits are not exposed to the guest via
XCR0.
Failing to allow FP+SSE first showed up as a QEMU live migration failure,
where migrating a VM from a pre-XSAVE host, e.g. Nehalem, to an XSAVE
host failed due to KVM rejecting KVM_SET_XSAVE. However, the bug also
causes problems even when migrating between XSAVE-capable hosts as
KVM_GET_SAVE won't set any bits in user_xfeatures if XSAVE isn't exposed
to the guest, i.e. KVM will fail to actually migrate FP+SSE.
Because KVM_{G,S}ET_XSAVE are designed to allowing migrating between
hosts with and without XSAVE, KVM_GET_XSAVE on a non-XSAVE (by way of
fpu_copy_guest_fpstate_to_uabi()) always sets the FP+SSE bits in the
header so that KVM_SET_XSAVE will work even if the new host supports
XSAVE.

Reinstate the per-vCPU guest_supported_xcr0 by partially reverting
commit 988896bb6182; the implicit assessment that guest_supported_xcr0 is
always the same as guest_fpu.fpstate->user_xfeatures was incorrect.
kvm_vcpu_after_set_cpuid() isn't the only place that sets user_xfeatures,
as user_xfeatures is set to fpu_user_cfg.default_features when guest_fpu
is allocated via fpu_alloc_guest_fpstate() => __fpstate_reset().
guest_supported_xcr0 on the other hand is zero-allocated. If userspace
never invokes KVM_SET_CPUID2, supported XCR0 will be '0', whereas the
allowed user XFEATURES will be non-zero.
Practically speaking, the edge case likely doesn't matter as no sane
userspace will live migrate a VM without ever doing KVM_SET_CPUID2. The
primary motivation is to prepare for KVM intentionally and explicitly
setting bits in user_xfeatures that are not set in guest_supported_xcr0.
Because KVM_{G,S}ET_XSAVE can be used to svae/restore FP+SSE state even
if the host doesn't support XSAVE, KVM needs to set the FP+SSE bits in
user_xfeatures even if they're not allowed in XCR0, e.g. because XCR0
isn't exposed to the guest. At that point, the simplest fix is to track
the two things separately (allowed save/restore vs. allowed XCR0).

cpufreq_get_hw_max_freq() returns max frequency in kHz as *unsigned int*,
while freq_inv_set_max_ratio() gets passed this frequency in Hz as 'u64'.
Multiplying max frequency by 1000 can potentially result in overflow --
multiplying by 1000ULL instead should avoid that...

Since commit:
ee017ee353506fce ("arm64/mm: avoid fixmap race condition when create pud mapping")
... once the kernel leave the SYSTEM_BOOTING state, the fixmap pagetable
entries are protected by the fixmap_lock mutex.
The new KPTI rewrite code uses __create_pgd_mapping() to create a
temporary pagetable. This happens in atomic context, after secondary
CPUs are brought up and the kernel has left the SYSTEM_BOOTING state.
Hence we try to acquire a mutex in atomic context, which is generally
unsound (though benign in this case as the mutex should be free and all
other CPUs are quiescent).
This patch avoids the issue by pulling the mutex out of alloc_init_pud()
and calling it at a higher level in the pagetable manipulation code.
This allows it to be used without locking where one CPU is known to be
in exclusive control of the machine, even after having left the
SYSTEM_BOOTING state.

The GAIT and all of its entries must be represented by physical
addresses as this structure is shared with underlying firmware.
We can keep a virtual address of the GAIT origin in order to
handle processing in the kernel, but when traversing the entries
we must again convert the physical AISB stored in that GAIT entry
into a virtual address in order to process it.
Note: this currently doesn't fix a real bug, since virtual addresses
are indentical to physical ones.

Since binutils 2.39, ld will print a warning if any stack section is
executable, which is the default for stack sections on files without a
.note.GNU-stack section.
This was fixed for x86 in commit ffcf9c5700e4 ("x86: link vdso and boot with -z noexecstack --no-warn-rwx-segments"),
but remained broken for UML, resulting in several warnings:
/usr/bin/ld: warning: arch/x86/um/vdso/vdso.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker

/usr/bin/ld: warning: vmlinux has a LOAD segment with RWX permissions
Link both the VDSO and vmlinux with -z noexecstack, fixing the warnings
about .note.GNU-stack sections. In addition, pass --no-warn-rwx-segments
to dodge the remaining warnings about LOAD segments with RWX permissions
in the kallsyms objects. (Note that this flag is apparently not
available on lld, so hide it behind a test for BFD, which is what the
x86 patch does.)

That "/dev/tty" came from the command line (which is automatically

The TLDP project tells the following about the /dev/tty:

The "(if any)" is important here, since it's possible for processes to

I think this was a simple typo and the author wanted tty0 there.

With commit 0c24e061196c ("mm: kmemleak: add rbtree and store physical
address for objects allocated with PA"), kmemleak started to put the
objects allocated with physical address onto object_phys_tree_root tree.
The kmemleak_free_part() therefore no longer worked as expected on
physically allocated objects (hyp_mem_base in this case) as it attempted to
search and remove things in object_tree_root tree.
Fix it by using kmemleak_free_part_phys() to unregister hyp_mem_base. This
fixes an immediate crash when booting a KVM host in protected mode with
kmemleak enabled.

commit 0060c8783330 ("net: stmmac: implement support for passive mode
converters via dt") has changed the plat->interface field semantics from
containing the PHY-mode to specifying the MAC-PCS interface mode. Due to
that the loongson32 platform code will leave the phylink interface
uninitialized with the PHY-mode intended by the means of the actual
platform setup. The commit-author most likely has just missed the
arch-specific code to fix. Let's mend the Loongson32 platform code then by
assigning the PHY-mode to the phy_interface field of the STMMAC platform
data.

riscv has an equivalent of arm bug fixed by 653d48b22166 ("arm: fix
really nasty sigreturn bug"); if signal gets caught by an interrupt that
hits when we have the right value in a0 (-513), *and* another signal
gets delivered upon sigreturn() (e.g. included into the blocked mask for
the first signal and posted while the handler had been running), the
syscall restart logics will see regs->cause equal to EXC_SYSCALL (we are
in a syscall, after all) and a0 already restored to its original value
(-513, which happens to be -ERESTARTNOINTR) and assume that we need to
apply the usual syscall restart logics.

The previous patch triggered a build failure for the debian kernel,
which has CONFIG_64BIT enabled, uses the CROSS_COMPILER environment
variable and uses ARCH=parisc to configure the kernel for 64-bit
support.
This patch weakens the previous patch while keeping the recommended way
to configure the kernel with:
ARCH=parisc -> build 32-bit kernel
ARCH=parisc64 -> build 64-bit kernel
while adding the possibility for debian to configure a 64-bit kernel
even if ARCH=parisc is set (PA8X00 CPU has to be selected and
CONFIG_64BIT needs to be enabled).
The downside of this patch is, that we now have a small window open
again where people may get it wrong: if they enable CONFIG_64BIT and try
to compile with a 32-bit compiler.

This fixes two issues: I truncated the warning's hart ID when porting to
the 64-bit hart ID code, and the original code's warning handling could
fire on an uninitialized hart ID.
The biggest change here is that riscv_cbom_block_size is no longer
initialized, as IMO the default isn't sane: there's nothing in the ISA
that mandates any specific cache block size, so falling back to one will
just silently produce the wrong answer on some systems. This also
changes the probing order so the cache block size is known before
enabling Zicbom support.
