POWER9 contains an off core mmu called the nest mmu (NMMU). This is
used by other hardware units on the chip to translate virtual
addresses into real addresses. The unit attempting an address
translation provides the majority of the context required for the
translation request except for the base address of the partition table
(ie. the PTCR) which needs to be programmed into the NMMU.

This patch adds a call to OPAL to set the PTCR for the nest mmu in
opal_init().

Relax the check preventing us from hotplugging into an offline node.

This limitation was added in commit 482ec7c4 ("[PATCH] powerpc numa:
Support sparse online node map") to prevent adding resources to an
uninitialized node.

These days, there is no harm in doing so. The addition will actually
cause the node to be initialized and onlined; add_memory_resource()
calls hotadd_new_pgdat() (if necessary) and node_set_online().

The flow of the main loop in parse_numa_properties() is overly
complicated. Simplify it to be less confusing and easier to read.
No functional change.

The end of the main loop in parse_numa_properties() looks like this:

	for_each_node_by_type(...) {
		...
		if (!condition) {
			if (--ranges)
				goto new_range;
			else
				continue;
		}

		statement();

		if (--ranges)
			goto new_range;
		/* else
		 *	continue; <- implicit, this is the end of the loop
		 */
	}

The only effect of !condition is to skip execution of statement(). This
can be rewritten in a simpler way:

	for_each_node_by_type(...) {
		...
		if (condition)
			statement();

		if (--ranges)
			goto new_range;
	}

The proto VSID is built using both the MMU context id and effective
segment ID (ESID). We should not have overlapping bits between those.
That could result in us having a VSID collision. With the current code
we missed masking the top bits of the ESID. This implies for kernel
address we ended up using the top 4 bits of the ESID as part of the
proto VSID, which is wrong.

The current code use the top 4 context values (0x7fffc - 0x7ffff) for
the kernel. With those context IDs used for the kernel, we don't run
into VSID collisions because we get the same proto VSID irrespective of
whether we mask the ESID bits or not. eg:

  ea         = 0xf000000000000000
  context    = 0x7ffff

  w/out masking:
  proto_vsid = (0x7ffff << 6 | 0xf000000000000000 >> 40)
	     = (0x1ffffc0 | 0xf00000)
	     =  0x1ffffc0

  with masking:
  proto_vsid = (0x7ffff << 6 | ((0xf000000000000000 >> 40) & 0x3f))
	     = (0x1ffffc0 | (0xf00000 & 0x3f))
	     =  0x1ffffc0 | 0)
	     =  0x1ffffc0

So although there is no bug, the code is still overly subtle, so fix it
to save ourselves pain in future.

With bpf_jit_binary_alloc(), we allocate at a page granularity and fill
the rest of the space with illegal instructions to mitigate BPF spraying
attacks, while having the actual JIT'ed BPF program at a random location
within the allocated space. Under this scenario, it would be better to
flush the entire allocated buffer rather than just the part containing
the actual program. We already flush the buffer from start to the end of
the BPF program. Extend this to include the illegal instructions after

During EEH recovery, we deconfigure all AFUs whilst leaving the
corresponding vPHB and virtual PCI device in place.

If something attempts to interact with the AFU's PCI config space (e.g.
running lspci) after the AFU has been deconfigured and before it's
reconfigured, cxl_pcie_{read,write}_config() will read invalid values from
the deconfigured struct cxl_afu and proceed to Oops when they try to
dereference pointers that have been set to NULL during deconfiguration.

Add a rwsem to struct cxl_afu so we can prevent interaction with config
space while the AFU is deconfigured.

+#define   LPCR_VRMASD_SH       47
+#define   LPCR_VRMASD          (ASM_CONST(1) << LPCR_VRMASD_SH)

We initialize the VRMA bits in LPCR to 0x00 in kvm. Hence using a
different mask value as above while updating lpcr should not have any
impact.

This patch updates it to the correct value.

These functions compute an IP checksum by computing a 64-bit sum and
folding it to 32 bits (the "nofold" in their names refers to folding
down to 16 bits).  However, doing (u32) (s + (s >> 32)) is not
sufficient to fold a 64-bit sum to 32 bits correctly.  The addition
can produce a carry out from bit 31, which needs to be added in to
the sum to produce the correct result.
