When building for LSE atomics (CONFIG_ARM64_LSE_ATOMICS), if the hardware
or toolchain doesn't support it the existing code will fallback to ll/sc
atomics. It achieves this by branching from inline assembly to a function
that is built with special compile flags. Further this results in the
clobbering of registers even when the fallback isn't used increasing
register pressure.
Improve this by providing inline implementations of both LSE and
ll/sc and use a static key to select between them, which allows for the
compiler to generate better atomics code. Put the LL/SC fallback atomics
in their own subsection to improve icache performance.

The A64 ISA accepts distinct (but overlapping) ranges of immediates for:
* add arithmetic instructions ('I' machine constraint)
* sub arithmetic instructions ('J' machine constraint)
* 32-bit logical instructions ('K' machine constraint)
* 64-bit logical instructions ('L' machine constraint)
... but we currently use the 'I' constraint for many atomic operations
using sub or logical instructions, which is not always valid.
When CONFIG_ARM64_LSE_ATOMICS is not set, this allows invalid immediates
to be passed to instructions, potentially resulting in a build failure.
When CONFIG_ARM64_LSE_ATOMICS is selected the out-of-line ll/sc atomics
always use a register as they have no visibility of the value passed by
the caller.
This patch adds a constraint parameter to the ATOMIC_xx and
__CMPXCHG_CASE macros so that we can pass appropriate constraints for
each case, with uses updated accordingly.
Unfortunately prior to GCC 8.1.0 the 'K' constraint erroneously accepted
'4294967295', so we must instead force the use of a register.

While the MMUs is disabled, I-cache speculation can result in
instructions being fetched from the PoC. During boot we may patch
instructions (e.g. for alternatives and jump labels), and these may be
dirty at the PoU (and stale at the PoC).
Thus, while the MMU is disabled in the KPTI pagetable fixup code we may
load stale instructions into the I-cache, potentially leading to
subsequent crashes when executing regions of code which have been
modified at runtime.
Similarly to commit:
8ec41987436d566f ("arm64: mm: ensure patched kernel text is fetched from PoU")
... we can invalidate the I-cache after enabling the MMU to prevent such
issues.
The KPTI pagetable fixup code itself should be clean to the PoC per the
boot protocol, so no maintenance is required for this code.

With 16K pages and 48-bit VAs, the PGD level of table has two entries,
and so the fixmap shares a PGD with the kernel image. Since commit:
f9040773b7bbbd9e ("arm64: move kernel image to base of vmalloc area")
... we copy the existing fixmap to the new fine-grained page tables at
the PUD level in this case. When walking to the new PUD, we forgot to
offset the PGD entry and always used the PGD entry at index 0, but this
worked as the kernel image and fixmap were in the low half of the TTBR1
address space.
As of commit:
14c127c957c1c607 ("arm64: mm: Flip kernel VA space")
... the kernel image and fixmap are in the high half of the TTBR1
address space, and hence use the PGD at index 1, but we didn't update
the fixmap copying code to account for this.
Thus, we'll erroneously try to copy the fixmap slots into a PUD under
the PGD entry at index 0. At the point we do so this PGD entry has not
been initialised, and thus we'll try to write a value to a small offset
from physical address 0, causing a number of potential problems.
Fix this be correctly offsetting the PGD. This is split over a few steps
for legibility.

Thanks to address translation being performed out of order with respect to
loads and stores, it is possible for a CPU to take a translation fault when
accessing a page that was mapped by a different CPU.
For example, in the case that one CPU maps a page and then sets a flag to
tell another CPU:
CPU 0
-----
MOV X0, <valid pte>
STR X0, [Xptep] // Store new PTE to page table
DSB ISHST
ISB
MOV X1, #1
STR X1, [Xflag] // Set the flag
CPU 1
-----
loop: LDAR X0, [Xflag] // Poll flag with Acquire semantics
CBZ X0, loop
LDR X1, [X2] // Translates using the new PTE
then the final load on CPU 1 can raise a translation fault because the
translation can be performed speculatively before the read of the flag and
marked as "faulting" by the CPU. This isn't quite as bad as it sounds
since, in reality, code such as:
CPU 0 CPU 1
----- -----
spin_lock(&lock); spin_lock(&lock);
*ptr = vmalloc(size); if (*ptr)
spin_unlock(&lock); foo = **ptr;
spin_unlock(&lock);
will not trigger the fault because there is an address dependency on CPU 1
which prevents the speculative translation. However, more exotic code where
the virtual address is known ahead of time, such as:
CPU 0 CPU 1
----- -----
spin_lock(&lock); spin_lock(&lock);
set_fixmap(0, paddr, prot); if (mapped)
mapped = true; foo = *fix_to_virt(0);
spin_unlock(&lock); spin_unlock(&lock);
could fault. This can be avoided by any of:
* Introducing broadcast TLB maintenance on the map path
* Adding a DSB;ISB sequence after checking a flag which indicates
that a virtual address is now mapped
* Handling the spurious fault
Given that we have never observed a problem due to this under Linux and
future revisions of the architecture are being tightened so that
translation table walks are effectively ordered in the same way as explicit
memory accesses, we no longer treat spurious kernel faults as fatal if an
AT instruction indicates that the access does not trigger a translation
fault.

Commit 24fe1b0efad4fcdd ("arm64: Remove unnecessary ISBs from
set_{pte,pmd,pud}") removed ISB instructions immediately following updates
to the page table, on the grounds that they are not required by the
architecture and a DSB alone is sufficient to ensure that subsequent data
accesses use the new translation:
DDI0487E_a, B2-128:
| ... no instruction that appears in program order after the DSB
| instruction can alter any state of the system or perform any part of
| its functionality until the DSB completes other than:
|
| * Being fetched from memory and decoded
| * Reading the general-purpose, SIMD and floating-point,
| Special-purpose, or System registers that are directly or indirectly
| read without causing side-effects.
However, the same document also states the following:
DDI0487E_a, B2-125:
| DMB and DSB instructions affect reads and writes to the memory system
| generated by Load/Store instructions and data or unified cache
| maintenance instructions being executed by the PE. Instruction fetches
| or accesses caused by a hardware translation table access are not
| explicit accesses.
which appears to claim that the DSB alone is insufficient. Unfortunately,
some CPU designers have followed the second clause above, whereas in Linux
we've been relying on the first. This means that our mapping sequence:
MOV X0, <valid pte>
STR X0, [Xptep] // Store new PTE to page table
DSB ISHST
LDR X1, [X2] // Translates using the new PTE
can actually raise a translation fault on the load instruction because the
translation can be performed speculatively before the page table update and
then marked as "faulting" by the CPU. For user PTEs, this is ok because we
can handle the spurious fault, but for kernel PTEs and intermediate table
entries this results in a panic().
Revert the offending commit to reintroduce the missing barriers.
