Accesses by userspace to random addresses outside the user or kernel
address range will generate an SLB fault. When we handle that fault we
classify the effective address into several classes, eg. user, kernel
linear, kernel virtual etc.
For addresses that are completely outside of any valid range, we
should not insert an SLB entry at all, and instead immediately an
exception.
In the past this was handled in two ways. Firstly we would check the
top nibble of the address (using REGION_ID(ea)) and that would tell us
if the address was user (0), kernel linear (c), kernel virtual (d), or
vmemmap (f). If the address didn't match any of these it was invalid.
Then for each type of address we would do a secondary check. For the
user region we check against H_PGTABLE_RANGE, for kernel linear we
would mask the top nibble of the address and then check the address
against MAX_PHYSMEM_BITS.
As part of commit 0034d395f89d ("powerpc/mm/hash64: Map all the kernel
regions in the same 0xc range") we replaced REGION_ID() with
get_region_id() and changed the masking of the top nibble to only mask
the top two bits, which introduced a bug.
Addresses less than (4 << 60) are still handled correctly, they are
either less than (1 << 60) in which case they are subject to the
H_PGTABLE_RANGE check, or they are correctly checked against
MAX_PHYSMEM_BITS.
However addresses from (4 << 60) to ((0xc << 60) - 1), are incorrectly
treated as kernel linear addresses in get_region_id(). Then the top
two bits are cleared by EA_MASK in slb_allocate_kernel() and the
address is checked against MAX_PHYSMEM_BITS, which it passes due to
the masking. The end result is we incorrectly insert SLB entries for
those addresses.
That is not actually catastrophic, having inserted the SLB entry we
will then go on to take a page fault for the address and at that point
we detect the problem and report it as a bad fault.
Still we should not be inserting those entries, or treating them as
kernel linear addresses in the first place. So fix get_region_id() to
detect addresses in that range and return an invalid region id, which
we cause use to not insert an SLB entry and directly report an
exception.

The kernel module is loaded into vmalloc region which is located below
to the PAGE_OFFSET. Hence the condition, pc < PAGE_OFFSET, in the
is_valid_bugaddr() will filter out all trap exceptions triggered
by kernel module. To support BUG() in kernel module, the condition is
changed to pc < VMALLOC_START.

The macro __BUG_INSN currently is defined as the "ebreak" opcode.
The is_valid_bugaddr() function compares the instruction pointed to by
$sepc with macro __BUG_INSN to check whether the current trap exception
is caused by an "ebreak" instruction. However, this check flow is possibly
erroneous because if C extension is supported, the expected trap
instruction "ebreak" is possibly translated to "c.ebreak" by the assembler.
Therefore, it requires a mechanism to distinguish the length of the
instruction in $spec and compare it to the correct trap instruction.

Currently sbi_remote_sfence_vma{,_asid} does not pass their arguments
to SBI at all, which is semantically incorrect.
Neither BBL nor OpenSBI is using these arguments at the moment, and
they just do a global flush instead. However we still need to provide
correct arguments.

switch_mm is an expensive operations that has two users.
flush_icache_deferred is only called within switch_mm and can be moved
together. The function is expected to be more complicated when ASID
support is added, so clean up eagerly.
By moving them to a separate file we also removes some excessive
dependency of tlbflush.h and cacheflush.h.

Currently, flush_icache_all is macro-expanded into a SBI call, yet no
asm/sbi.h is included in asm/cacheflush.h. This could be moved to
mm/cacheflush.c instead (SBI call will dominate performance-wise and
there is no worry to not have it inlined.
Currently, flush_icache_mm stays in kernel/smp.c, which looks like a
hack to prevent it from being compiled when CONFIG_SMP=n. It should
also be in mm/cacheflush.c.

We should prefer accessing CSRs using their CSR numbers because:
1. It compiles fine with older toolchains.
2. We can use latest CSR names in #define macro names of CSR numbers
as-per RISC-V spec.
3. We can access newly added CSRs even if toolchain does not recognize
newly addes CSRs by name.

Pull ARM SoC platform updates from Olof Johansson:
"SoC updates, mostly refactorings and cleanups of old legacy platforms.
Major themes this release:
- Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
- Moving some of the ep93xx headers around to get it closer to
multiplatform enabled.
- Cleanups of Davinci
This also contains a few patches that were queued up as fixes before
5.1 but I didn't get sent in before release"

We call get_region_id() without validating the ea value. That means
with a wrong ea value we hit the BUG as below.
kernel BUG at arch/powerpc/include/asm/book3s/64/hash.h:129!
Oops: Exception in kernel mode, sig: 5 [#1]

Fix this by removing the VM_BUG_ON. All callers make sure the returned

Commit 691efbedc60d ("arm64: vdso: use $(LD) instead of $(CC) to
link VDSO") switched to using LD explicitly. The --build-id option
needs to be passed explicitly, similar to x86. Add this option.

The arm64 ptdump code can race with concurrent modification of the
kernel page tables. At the time this was added, this was sound as:
* Modifications to leaf entries could result in stale information being
logged, but would not result in a functional problem.
* Boot time modifications to non-leaf entries (e.g. freeing of initmem)
were performed when the ptdump code cannot be invoked.
* At runtime, modifications to non-leaf entries only occurred in the
vmalloc region, and these were strictly additive, as intermediate
entries were never freed.
However, since commit:
commit 324420bf91f6 ("arm64: add support for ioremap() block mappings")
... it has been possible to create huge mappings in the vmalloc area at
runtime, and as part of this existing intermediate levels of table my be
removed and freed.
It's possible for the ptdump code to race with this, and continue to
walk tables which have been freed (and potentially poisoned or
reallocated). As a result of this, the ptdump code may dereference bogus
addresses, which could be fatal.
Since huge-vmap is a TLB and memory optimization, we can disable it when
the runtime ptdump code is in use to avoid this problem.

clock_getres in the vDSO library has to preserve the same behaviour
of posix_get_hrtimer_res().
In particular, posix_get_hrtimer_res() does:
sec = 0;
ns = hrtimer_resolution;
and hrtimer_resolution depends on the enablement of the high
resolution timers that can happen either at compile or at run time.
Fix the nds32 vdso implementation of clock_getres keeping a copy of
hrtimer_resolution in vdso data and using that directly.
