-/**
- * read_barrier_depends - Flush all pending reads that subsequents reads
- * depend on.
- *
- * No data-dependent reads from memory-like regions are ever reordered
- * over this barrier.  All reads preceding this primitive are guaranteed
- * to access memory (but not necessarily other CPUs' caches) before any
- * reads following this primitive that depend on the data return by
- * any of the preceding reads.  This primitive is much lighter weight than
- * rmb() on most CPUs, and is never heavier weight than is
- * rmb().
- *
- * These ordering constraints are respected by both the local CPU
- * and the compiler.
- *
- * Ordering is not guaranteed by anything other than these primitives,
- * not even by data dependencies.  See the documentation for
- * memory_barrier() for examples and URLs to more information.
- *
- * For example, the following code would force ordering (the initial
- * value of "a" is zero, "b" is one, and "p" is "&a"):
- *
- * <programlisting>
- *	CPU 0				CPU 1
- *
- *	b = 2;
- *	memory_barrier();
- *	p = &b;				q = p;
- *					read_barrier_depends();
- *					d = *q;
- * </programlisting>
- *
- * because the read of "*q" depends on the read of "p" and these
- * two reads are separated by a read_barrier_depends().  However,
- * the following code, with the same initial values for "a" and "b":
- *
- * <programlisting>
- *	CPU 0				CPU 1
- *
- *	a = 2;
- *	memory_barrier();
- *	b = 3;				y = b;
- *					read_barrier_depends();
- *					x = a;
- * </programlisting>
- *
- * does not enforce ordering, since there is no data dependency between
- * the read of "a" and the read of "b".  Therefore, on some CPUs, such
- * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
- * in cases like this where there are no data dependencies.

-	  Various binutils versions can resolve Thumb-2 branches to
-	  locally-defined, preemptible global symbols as short-range "b.n"
-	  branch instructions.
-
-	  This is a problem, because there's no guarantee the final
-	  destination of the symbol, or any candidate locations for a
-	  trampoline, are within range of the branch.  For this reason, the
-	  kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
-	  relocation in modules at all, and it makes little sense to add
-	  support.
-
-	  The symptom is that the kernel fails with an "unsupported
-	  relocation" error when loading some modules.
-
-	  Until fixed tools are available, passing
-	  -fno-optimize-sibling-calls to gcc should prevent gcc generating
-	  code which hits this problem, at the cost of a bit of extra runtime
-	  stack usage in some cases.
-
-	  The problem is described in more detail at:
-	      https://bugs.launchpad.net/binutils-linaro/+bug/725126
-
-	  Only Thumb-2 kernels are affected.
-
-	  Unless you are sure your tools don't have this problem, say Y.

+	  This kernel feature is useful for number crunching applications
+	  that may need to compute untrusted bytecode during their
+	  execution. By using pipes or other transports made available to
+	  the process as file descriptors supporting the read/write
+	  syscalls, it's possible to isolate those applications in
+	  their own address space using seccomp. Once seccomp is
+	  enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
+	  and the task is only allowed to execute a few safe syscalls
+	  defined by each seccomp mode.

-KVM/MIPS Trap & Emulate Release Notes
-=====================================
-
-(1) KVM/MIPS should support MIPS32R2 and beyond. It has been tested on the following platforms:
-    Malta Board with FPGA based 34K
-    Sigma Designs TangoX board with a 24K based 8654 SoC.
-    Malta Board with 74K @ 1GHz
-
-(2) Both Guest kernel and Guest Userspace execute in UM.
-    Guest User address space:   0x00000000 -> 0x40000000
-    Guest Kernel Unmapped:      0x40000000 -> 0x60000000
-    Guest Kernel Mapped:        0x60000000 -> 0x80000000
-
-    Guest Usermode virtual memory is limited to 1GB.
-
-(2) 16K Page Sizes: Both Host Kernel and Guest Kernel should have the same page size, currently at least 16K.
-    Note that due to cache aliasing issues, 4K page sizes are NOT supported.
-
-(3) No HugeTLB Support
-    Both the host kernel and Guest kernel should have the page size set to 16K.
-    This will be implemented in a future release.
-
-(4) KVM/MIPS does not have support for SMP Guests
-    Linux-3.7-rc2 based SMP guest hangs due to the following code sequence in the generated TLB handlers:
-	LL/TLBP/SC.  Since the TLBP instruction causes a trap the reservation gets cleared
-	when we ERET back to the guest. This causes the guest to hang in an infinite loop.
-	This will be fixed in a future release.
-
-(5) Use Host FPU
-    Currently KVM/MIPS emulates a 24K CPU without a FPU.
-    This will be fixed in a future release

+ * The majority of the complexity in supporting SR-IOV on PowerNV comes from
+ * the need to put the MMIO space for each VF into a separate PE. Internally
+ * the PHB maps MMIO addresses to a specific PE using the "Memory BAR Table".
+ * The MBT historically only applied to the 64bit MMIO window of the PHB
+ * so it's common to see it referred to as the "M64BT".
+ *
+ * An MBT entry stores the mapped range as an <base>,<mask> pair. This forces
+ * the address range that we want to map to be power-of-two sized and aligned.
+ * For conventional PCI devices this isn't really an issue since PCI device BARs
+ * have the same requirement.
+ *
+ * For a SR-IOV BAR things are a little more awkward since size and alignment
+ * are not coupled. The alignment is set based on the the per-VF BAR size, but
+ * the total BAR area is: number-of-vfs * per-vf-size. The number of VFs
+ * isn't necessarily a power of two, so neither is the total size. To fix that
+ * we need to finesse (read: hack) the Linux BAR allocator so that it will
+ * allocate the SR-IOV BARs in a way that lets us map them using the MBT.
+ *
+ * The changes to size and alignment that we need to do depend on the "mode"
+ * of MBT entry that we use. We only support SR-IOV on PHB3 (IODA2) and above,
+ * so as a baseline we can assume that we have the following BAR modes
+ * available:
+ *
+ *   NB: $PE_COUNT is the number of PEs that the PHB supports.
+ *
+ * a) A segmented BAR that splits the mapped range into $PE_COUNT equally sized
+ *    segments. The n'th segment is mapped to the n'th PE.
+ * b) An un-segmented BAR that maps the whole address range to a specific PE.
+ *
+ *
+ * We prefer to use mode a) since it only requires one MBT entry per SR-IOV BAR
+ * For comparison b) requires one entry per-VF per-BAR, or:
+ * (num-vfs * num-sriov-bars) in total. To use a) we need the size of each segment
+ * to equal the size of the per-VF BAR area. So:
+ *
+ *	new_size = per-vf-size * number-of-PEs
+ *
+ * The alignment for the SR-IOV BAR also needs to be changed from per-vf-size
+ * to "new_size", calculated above. Implementing this is a convoluted process
+ * which requires several hooks in the PCI core:
+ *
+ * 1. In pcibios_add_device() we call pnv_pci_ioda_fixup_iov().
+ *
+ *    At this point the device has been probed and the device's BARs are sized,
+ *    but no resource allocations have been done. The SR-IOV BARs are sized
+ *    based on the maximum number of VFs supported by the device and we need
+ *    to increase that to new_size.
+ *
+ * 2. Later, when Linux actually assigns resources it tries to make the resource
+ *    allocations for each PCI bus as compact as possible. As a part of that it
+ *    sorts the BARs on a bus by their required alignment, which is calculated
+ *    using pci_resource_alignment().
+ *
+ *    For IOV resources this goes:
+ *    pci_resource_alignment()
+ *        pci_sriov_resource_alignment()
+ *            pcibios_sriov_resource_alignment()
+ *                pnv_pci_iov_resource_alignment()
+ *
+ *    Our hook overrides the default alignment, equal to the per-vf-size, with
+ *    new_size computed above.
+ *
+ * 3. When userspace enables VFs for a device:
+ *
+ *    sriov_enable()
+ *       pcibios_sriov_enable()
+ *           pnv_pcibios_sriov_enable()
+ *
+ *    This is where we actually allocate PE numbers for each VF and setup the
+ *    MBT mapping for each SR-IOV BAR. In steps 1) and 2) we setup an "arena"
+ *    where each MBT segment is equal in size to the VF BAR so we can shift
+ *    around the actual SR-IOV BAR location within this arena. We need this
+ *    ability because the PE space is shared by all devices on the same PHB.
+ *    When using mode a) described above segment 0 in maps to PE#0 which might
+ *    be already being used by another device on the PHB.
+ *
+ *    As a result we need allocate a contigious range of PE numbers, then shift
+ *    the address programmed into the SR-IOV BAR of the PF so that the address
+ *    of VF0 matches up with the segment corresponding to the first allocated
+ *    PE number. This is handled in pnv_pci_vf_resource_shift().
+ *
+ *    Once all that is done we return to the PCI core which then enables VFs,
+ *    scans them and creates pci_devs for each. The init process for a VF is
+ *    largely the same as a normal device, but the VF is inserted into the IODA
+ *    PE that we allocated for it rather than the PE associated with the bus.
+ *
+ * 4. When userspace disables VFs we unwind the above in
+ *    pnv_pcibios_sriov_disable(). Fortunately this is relatively simple since
+ *    we don't need to validate anything, just tear down the mappings and
+ *    move SR-IOV resource back to its "proper" location.
+ *
+ * That's how mode a) works. In theory mode b) (single PE mapping) is less work
+ * since we can map each individual VF with a separate BAR. However, there's a
+ * few limitations:
+ *
+ * 1) For IODA2 mode b) has a minimum alignment requirement of 32MB. This makes
+ *    it only usable for devices with very large per-VF BARs. Such devices are
+ *    similar to Big Foot. They definitely exist, but I've never seen one.
+ *
+ * 2) The number of MBT entries that we have is limited. PHB3 and PHB4 only
+ *    16 total and some are needed for. Most SR-IOV capable network cards can support
+ *    more than 16 VFs on each port.
+ *
+ * We use b) when using a) would use more than 1/4 of the entire 64 bit MMIO
+ * window of the PHB.
+ *
+ *
+ *
+ * PHB4 (IODA3) added a few new features that would be useful for SR-IOV. It
+ * allowed the MBT to map 32bit MMIO space in addition to 64bit which allows
+ * us to support SR-IOV BARs in the 32bit MMIO window. This is useful since
+ * the Linux BAR allocation will place any BAR marked as non-prefetchable into
+ * the non-prefetchable bridge window, which is 32bit only. It also added two
+ * new modes:
+ *
+ * c) A segmented BAR similar to a), but each segment can be individually
+ *    mapped to any PE. This is matches how the 32bit MMIO window worked on
+ *    IODA1&2.
+ *
+ * d) A segmented BAR with 8, 64, or 128 segments. This works similarly to a),
+ *    but with fewer segments and configurable base PE.
+ *
+ *    i.e. The n'th segment maps to the (n + base)'th PE.
+ *
+ *    The base PE is also required to be a multiple of the window size.
+ *
+ * Unfortunately, the OPAL API doesn't currently (as of skiboot v6.6) allow us
+ * to exploit any of the IODA3 features.

- * Theory of operation
- * -------------------
- *
- * This file provides the core code for a forward memory copy used in
- * the implementation of memcopy(), copy_to_user() and copy_from_user().
- *
- * The including file must define the following accessor macros
- * according to the need of the given function:
- *
- * ldr1w ptr reg abort
- *
- *	This loads one word from 'ptr', stores it in 'reg' and increments
- *	'ptr' to the next word. The 'abort' argument is used for fixup tables.
- *
- * ldr4w ptr reg1 reg2 reg3 reg4 abort
- * ldr8w ptr, reg1 reg2 reg3 reg4 reg5 reg6 reg7 reg8 abort
- *
- *	This loads four or eight words starting from 'ptr', stores them
- *	in provided registers and increments 'ptr' past those words.
- *	The'abort' argument is used for fixup tables.
- *
- * ldr1b ptr reg cond abort
- *
- *	Similar to ldr1w, but it loads a byte and increments 'ptr' one byte.
- *	It also must apply the condition code if provided, otherwise the
- *	"al" condition is assumed by default.
- *
- * str1w ptr reg abort
- * str8w ptr reg1 reg2 reg3 reg4 reg5 reg6 reg7 reg8 abort
- * str1b ptr reg cond abort
- *
- *	Same as their ldr* counterparts, but data is stored to 'ptr' location
- *	rather than being loaded.
- *
- * enter
- *
- *	Preserve the provided registers on the stack plus any additional
- *	data as needed by the implementation including this code. Called
- *	upon code entry.
- *
- * exit
- *
- *	Restore registers with the values previously saved with the
- *	'preserv' macro. Called upon code termination.
