commit 095507dc1350b3a2b8b39fdc05edba0c10859eca upstream.
Systems configured with CONFIG_ZONE_DMA32, CONFIG_ZONE_NORMAL and
!CONFIG_ZONE_DMA will fail to properly setup ARCH_LOW_ADDRESS_LIMIT. The
limit will default to ~0ULL, effectively spanning the whole memory,
which is too high for a configuration that expects low memory to be
capped at 4GB.Fix ARCH_LOW_ADDRESS_LIMIT by falling back to arm64_dma32_phys_limit
when arm64_dma_phys_limit isn't set. arm64_dma32_phys_limit will honour
CONFIG_ZONE_DMA32, or span the entire memory when not enabled.Fixes: 1a8e1cef7603 ("arm64: use both ZONE_DMA and ZONE_DMA32")

We use non-canonical CFI jump tables with CONFIG_CFI_CLANG, which
means the compiler replaces function address references with the
address of the function's CFI jump table entry. This results in
__pa_symbol(function), for example, returning the physical address
of the jump table entry, which can lead to address space confusion
since the jump table itself points to a virtual address. The same
issue happens when passing function pointers to hypervisor code
running at EL2.This change adds __va_function and __pa_function macros, which use
inline assembly to take the actual function address instead, and
changes the relevant code to use these macros.Bug: 145210207

Disable CFI checking for functions that switch to linear mapping and
make an indirect call to a physical address, since the compiler only
understands virtual addresses.Bug: 145210207

Non-coherent devices on systems that support a system or
last level cache may want to request that allocations be
cached in the system cache. For memory that is allocated
by the kernel, and used for DMA with devices, the memory
attributes used for CPU access should match the memory
attributes that will be used for device access.The memory attributes that need to be programmed into
the MAIR for system cache usage are:0xf4 - Normal memory, outer write back read/write allocate,
inner non-cacheable.There is currently no support for this memory attribute for
CPU mappings, so add it.Bug: 176778547

Reducing the section size helps reduce wastage of reserved memory
for huge memory holes in sparsemem model. But having a much smaller
section size bits could break PMD mappings for vmemmap and wouldn't
accomodate the highest order page for certain page size granule configs.
It is determined that SECTION_SIZE_BITS of 27 (128MB) could be ideal
default value for 4K_PAGES that gives least section size without breaking
PMD based vmemmap mappings. For simplicity, 16K_PAGES could follow the
same as 4K_PAGES. And the least SECTION_SIZE_BITS for 64K_PAGES is 29
that could accomodate MAX_ORDER.Signed-off-by: Sudarshan Rajagopalan

After certain memory blocks are offlined, some usecases require that the
page-table mappings are removed while still keeping the memblock device nodes,
memory resources and the memmap entries intact. This is to avoid the overhead
involved in using 'remove_memory' if the offlined blocks will be added/onlined
back into the system at later point. {populate/depopulate}_range_driver_managed
provide the abilty to drivers to tear-down and create page-table mappings of
memory blocks that its managing, without having to use 'remove_memory' and
friends for the purpose.
These functions does not interfere with mappings of boot memory or resources
that isn't owned by the driver.Bug: 171907330

This issue will result in the TLB aintenance across the clusters not working
as expected due to some VA and ASID bits get corruptedThe SW workaround is: use the vmalle1is if VA larger than 36bits or
ASID[15:12] is not zero, otherwise, we use original TLB maintenance path.Note: To simplify the code, we did not check VA[40] bit specifically

Pull arm64 fixes from Will Deacon:
"I'm sad to say that we've got an unusually large arm64 fixes pull for
rc7 which addresses numerous significant instrumentation issues with
our entry code.Without these patches, lockdep is hopelessly unreliable in some
configurations [1,2] and syzkaller is therefore not a lot of use
because it's so noisy.Although much of this has always been broken, it appears to have been
exposed more readily by other changes such as 044d0d6de9f5 ("lockdep:
Only trace IRQ edges") and general lockdep improvements around IRQ
tracing and NMIs.Fixing this properly required moving much of the instrumentation hooks
from our entry assembly into C, which Mark has been working on for the
last few weeks. We're not quite ready to move to the recently added
generic functions yet, but the code here has been deliberately written
to mimic that closely so we can look at cleaning things up once we
have a bit more breathing room.Having said all that, the second version of these patches was posted
last week and I pushed it into our CI (kernelci and cki) along with a
commit which forced on PROVE_LOCKING, NOHZ_FULL and
CONTEXT_TRACKING_FORCE. The result? We found a real bug in the
md/raid10 code [3].Oh, and there's also a really silly typo patch that's unrelated.
Summary:
- Fix numerous issues with instrumentation and exception entry
- Fix hideous typo in unused register field definition"

If we get a FSC_PERM fault, just using (logging_active && writable) to
determine calling kvm_pgtable_stage2_map(). There will be two more cases
we should consider.(1) After logging_active is configged back to false from true. When we
get a FSC_PERM fault with write_fault and adjustment of hugepage is needed,
we should merge tables back to a block entry. This case is ignored by still
calling kvm_pgtable_stage2_relax_perms(), which will lead to an endless
loop and guest panic due to soft lockup.(2) We use (FSC_PERM && logging_active && writable) to determine
collapsing a block entry into a table by calling kvm_pgtable_stage2_map().
But sometimes we may only need to relax permissions when trying to write
to a page other than a block.
In this condition,using kvm_pgtable_stage2_relax_perms() will be fine.The ISS filed bit[1:0] in ESR_EL2 regesiter indicates the stage2 lookup
level at which a D-abort or I-abort occurred. By comparing granule of
the fault lookup level with vma_pagesize, we can strictly distinguish
conditions of calling kvm_pgtable_stage2_relax_perms() or
kvm_pgtable_stage2_map(), and the above two cases will be well considered.Suggested-by: Keqian Zhu

Exceptions which can be taken at (almost) any time are consdiered to be
NMIs. On arm64 that includes:* SDEI events
* GICv3 Pseudo-NMIs
* Kernel stack overflows
* Unexpected/unhandled exceptions... but currently debug exceptions (BRKs, breakpoints, watchpoints,
single-step) are not considered NMIs.As these can be taken at any time, kernel features (lockdep, RCU,
ftrace) may not be in a consistent kernel state. For example, we may
take an NMI from the idle code or partway through an entry/exit path.While nmi_enter() and nmi_exit() handle most of this state, notably they
don't save/restore the lockdep state across an NMI being taken and
handled. When interrupts are enabled and an NMI is taken, lockdep may
see interrupts become disabled within the NMI code, but not see
interrupts become enabled when returning from the NMI, leaving lockdep
believing interrupts are disabled when they are actually disabled.The x86 code handles this in idtentry_{enter,exit}_nmi(), which will
shortly be moved to the generic entry code. As we can't use either yet,
we copy the x86 approach in arm64-specific helpers. All the NMI
entrypoints are marked as noinstr to prevent any instrumentation
handling code being invoked before the state has been corrected.Signed-off-by: Mark Rutland

There are periods in kernel mode when RCU is not watching and/or the
scheduler tick is disabled, but we can still take exceptions such as
interrupts. The arm64 exception handlers do not account for this, and
it's possible that RCU is not watching while an exception handler runs.The x86/generic entry code handles this by ensuring that all (non-NMI)
kernel exception handlers call irqentry_enter() and irqentry_exit(),
which handle RCU, lockdep, and IRQ flag tracing. We can't yet move to
the generic entry code, and already hadnle the userkernel transitions
elsewhere, so we add new kernelkernel transition helpers alog the
lines of the generic entry code.Since we now track interrupts becoming masked when an exception is
taken, local_daif_inherit() is modified to track interrupts becoming
re-enabled when the original context is inherited. To balance the
entry/exit paths, each handler masks all DAIF exceptions before
exit_to_kernel_mode().Signed-off-by: Mark Rutland

Exceptions from EL1 may be taken when RCU isn't watching (e.g. in idle
sequences), or when the lockdep hardirqs transiently out-of-sync with
the hardware state (e.g. in the middle of local_irq_enable()). To
correctly handle these cases, we'll need to save/restore this state
across some exceptions taken from EL1.A series of subsequent patches will update EL1 exception handlers to
handle this. In preparation for this, and to avoid dependencies between
those patches, this patch adds two new fields to struct pt_regs so that
exception handlers can track this state.Note that this is placed in pt_regs as some entry/exit sequences such as
el1_irq are invoked from assembly, which makes it very difficult to add
a separate structure as with the irqentry_state used by x86. We can
separate this once more of the exception logic is moved to C. While the
fields only need to be bool, they are both made u64 to keep pt_regs
16-byte aligned.There should be no functional change as a result of this patch.

When built with PROVE_LOCKING, NO_HZ_FULL, and CONTEXT_TRACKING_FORCE
will WARN() at boot time that interrupts are enabled when we call
context_tracking_user_enter(), despite the DAIF flags indicating that
IRQs are masked.The problem is that we're not tracking IRQ flag changes accurately, and
so lockdep believes interrupts are enabled when they are not (and
vice-versa). We can shuffle things so to make this more accurate. For
kernel->user transitions there are a number of constraints we need to
consider:1) When we call __context_tracking_user_enter() HW IRQs must be disabled
and lockdep must be up-to-date with this.2) Userspace should be treated as having IRQs enabled from the PoV of
both lockdep and tracing.3) As context_tracking_user_enter() stops RCU from watching, we cannot
use RCU after calling it.4) IRQ flag tracing and lockdep have state that must be manipulated
before RCU is disabled.... with similar constraints applying for user->kernel transitions, with
the ordering reversed.The generic entry code has enter_from_user_mode() and
exit_to_user_mode() helpers to handle this. We can't use those directly,
so we add arm64 copies for now (without the instrumentation markers
which aren't used on arm64). These replace the existing user_exit() and
user_exit_irqoff() calls spread throughout handlers, and the exception
unmasking is left as-is.Note that:
* The accounting for debug exceptions from userspace now happens in
el0_dbg() and ret_to_user(), so this is removed from
debug_exception_enter() and debug_exception_exit(). As
user_exit_irqoff() wakes RCU, the userspace-specific check is removed.* The accounting for syscalls now happens in el0_svc(),
el0_svc_compat(), and ret_to_user(), so this is removed from
el0_svc_common(). This does not adversely affect the workaround for
erratum 1463225, as this does not depend on any of the state tracking.* In ret_to_user() we mask interrupts with local_daif_mask(), and so we
need to inform lockdep and tracing. Here a trace_hardirqs_off() is
sufficient and safe as we have not yet exited kernel context and RCU
is usable.* As PROVE_LOCKING selects TRACE_IRQFLAGS, the ifdeferry in entry.S only
needs to check for the latter.* EL0 SError handling will be dealt with in a subsequent patch, as this
needs to be treated as an NMI.Prior to this patch, booting an appropriately-configured kernel would
result in spats as below:| DEBUG_LOCKS_WARN_ON(lockdep_hardirqs_enabled())
