      powerpc: Remove leftover cputime_to_nsecs call causing build error · 9f3768e0
      Frédéric Weisbecker authored 
      This type conversion is a leftover that got ignored during the kcpustat
conversion to nanosecs, resulting in build breakage with config having
CONFIG_NO_HZ_FULL=y.

	arch/powerpc/kernel/time.c: In function 'running_clock':
	arch/powerpc/kernel/time.c:712:2: error: implicit declaration of function 'cputime_to_nsecs' [-Werror=implicit-function-declaration]
	  return local_clock() - cputime_to_nsecs(kcpustat_this_cpu->cpustat[CPUTIME_STEAL]);

All we need is to remove it.

      powerpc/optprobes: Fix TOC handling in optprobes trampoline · f558b37b
      Naveen N. Rao authored 
      Optprobes on powerpc are limited to kernel text area. We decided to also
optimize kretprobe_trampoline since that is also in kernel text area.
However,we failed to take into consideration the fact that the same
trampoline is also used to catch function returns from kernel modules.
As an example:

  $ sudo modprobe kobject-example
  $ sudo bash -c "echo 'r foo_show+8' > /sys/kernel/debug/tracing/kprobe_events"
  $ sudo bash -c "echo 1 > /sys/kernel/debug/tracing/events/kprobes/enable"
  $ sudo cat /sys/kernel/debug/kprobes/list
  c000000000041350  k  kretprobe_trampoline+0x0    [OPTIMIZED]
  d000000000e00200  r  foo_show+0x8  kobject_example
  $ cat /sys/kernel/kobject_example/foo
  Segmentation fault

With the below (trimmed) splat in dmesg:

      powerpc/pseries: Advertise Hot Plug Event support to firmware · 3dbbaf20
      Michael Roth authored 
      With the inclusion of commit 333f7b76 ("powerpc/pseries: Implement
indexed-count hotplug memory add") and commit 75384347
("powerpc/pseries: Implement indexed-count hotplug memory remove"), we
now have complete handling of the RTAS hotplug event format as described
by PAPR via ACR "PAPR Changes for Hotplug RTAS Events".

This capability is indicated by byte 6, bit 2 (5 in IBM numbering) of
architecture option vector 5, and allows for greater control over
cpu/memory/pci hot plug/unplug operations.

Existing pseries kernels will utilize this capability based on the
existence of the /event-sources/hot-plug-events DT property, so we
only need to advertise it via CAS and do not need a corresponding
FW_FEATURE_* value to test for.

      cxl: fix nested locking hang during EEH hotplug · 171ed0fc
      Andrew Donnellan authored 
      Commit 14a3ae34 ("cxl: Prevent read/write to AFU config space while AFU
not configured") introduced a rwsem to fix an invalid memory access that
occurred when someone attempts to access the config space of an AFU on a
vPHB whilst the AFU is deconfigured, such as during EEH recovery.

It turns out that it's possible to run into a nested locking issue when EEH
recovery fails and a full device hotplug is required.
cxl_pci_error_detected() deconfigures the AFU, taking a writer lock on
configured_rwsem. When EEH recovery fails, the EEH code calls
pci_hp_remove_devices() to remove the device, which in turn calls
cxl_remove() -> cxl_pci_remove_afu() -> pci_deconfigure_afu(), which tries
to grab the writer lock that's already held.

Standard rwsem semantics don't express what we really want to do here and
don't allow for nested locking. Fix this by replacing the rwsem with an
atomic_t which we can control more finely. Allow the AFU to be locked
multiple times so long as there are no readers.

      powerpc/pseries: Revert 'Auto-online hotplugged memory' · 943db62c
      Nathan Fontenot authored 
      This reverts commit ec999072 ("powerpc/pseries: Auto-online
hotplugged memory"), and 9dc51281 ("powerpc: Fix unused function
warning 'lmb_to_memblock'").

Using the auto-online acpability does online added memory but does not
update the associated device struct to indicate that the memory is
online. This causes the pseries memory DLPAR code to fail when trying to
remove a LMB that was previously removed and added back. This happens
when validating that the LMB is removable.

This patch reverts to the previous behavior of calling device_online()
to online the LMB when it is DLPAR added and moves the lmb_to_memblock()
routine out of CONFIG_MEMORY_HOTREMOVE now that we call it for add.

      powerpc/64: Implement clear_bit_unlock_is_negative_byte() · d11914b2
      Nicholas Piggin authored 
      Commit b91e1302 ("mm: optimize PageWaiters bit use for
unlock_page()") added a special bitop function to speed up
unlock_page(). Implement this for 64-bit powerpc.

This improves the unlock_page() core code from this:

	li	9,1
	lwsync
1:	ldarx	10,0,3,0
	andc	10,10,9
	stdcx.	10,0,3
	bne-	1b
	ori	2,2,0
	ld	9,0(3)
	andi.	10,9,0x80
	beqlr
	li	4,0
	b	wake_up_page_bit

To this:

	li	10,1
	lwsync
1:	ldarx	9,0,3,0
	andc	9,9,10
	stdcx.	9,0,3
	bne-	1b
	andi.	10,9,0x80
	beqlr
	li	4,0
	b	wake_up_page_bit

In a test of elapsed time for dd writing into 16GB of already-dirty
pagecache on a POWER8 with 4K pages, which has one unlock_page per 4kB
this patch reduced overhead by 1.1%:

      drivers/pci/hotplug: Mask PDC interrupt if required · 454593e5
      Gavin Shan authored 
      We're supporting surprise hotplug on PCI slots behind root port
or PCIe switch downstream ports, which don't claim the capability
in hardware register (offset: PCIe cap + PCI_EXP_SLTCAP). PEX8718
is one of the examples. For those PCI slots, the PDC (Presence
Detection Change) event isn't reliable and the underly (skiboot)
firmware has best judgement.

This masks the PDC event when skiboot requests by "ibm,slot-broken-pdc"
property in PCI slot's device-tree node.

      drivers/pci/hotplug: Fix initial state for empty slot · d0c42497
      Gavin Shan authored 
      In PowerNV PCI hotplug driver, the initial PCI slot's state is set
to PNV_PHP_STATE_POPULATED if no PCI devices are connected to the
slot. The PCI devices that are hot added to the slot won't be probed
and populated because of the check in pnv_php_enable():

        /* Check if the slot has been configured */
        if (php_slot->state != PNV_PHP_STATE_REGISTERED)
                return 0;

This fixes the issue by leaving the slot in PNV_PHP_STATE_REGISTERED
state initially if nothing is connected to the slot.

      drivers/pci/hotplug: Handle presence detection change properly · d7d55536

      The surprise hotplug is driven by interrupt in PowerNV PCI hotplug
driver. In the interrupt handler, pnv_php_interrupt(), we bail when
pnv_pci_get_presence_state() returns zero wrongly. It causes the
presence change event is always ignored incorrectly.

This fixes the issue by bailing on error (non-zero value) returned
from pnv_pci_get_presence_state().

  3.  All bfd_* types and casts have been removed.
  4.  Optimizations related to opcd_indices have been removed.
  5.  The dialect is set based on cpu features.
  6.  PPC_OPCODE_CLASSIC is no longer supported in the new
      disassembler.
  7.  VLE opcode parsing and printing has been stripped.
  8.  Coding style conventions used for those routines has
      been retained and it does not match our CodingStyle.
  9.  The highest supported dialect is POWER9.
  10. Defined ATTRIBUTE_UNUSED in ppc-dis.c.
  11. Defined _(x) in ppc-dis.c.
