Diego Elio Pettenò 679b2ec8e0 scsi: sr: remove references to BLK_DEV_SR_VENDOR, leave it enabled
This kernel configuration is basically enabling/disabling sr driver quirks
detection. While these quirks are for fairly rare devices (very old CD
burners, and a glucometer), the additional detection of these models is a
very minimal amount of code.

The logic behind the quirks is always built into the sr driver.

This also removes the config from all the defconfig files that are enabling
this already.

Michael Ellerman 76e4bd9336 powerpc/configs: Drop CONFIG_QLGE which moved to staging
The QLGE driver moved to staging in commit 955315b0dc ("qlge: Move
drivers/net/ethernet/qlogic/qlge/ to drivers/staging/qlge/"), meaning
our defconfigs that enable it have no effect as we don't enable
CONFIG_STAGING.

It sounds like the device is obsolete, so drop the driver.

Andrew Donnellan 8b856a0942 powerpc/configs: Disable SCOM_DEBUGFS in powernv_defconfig
SCOM_DEBUGFS is really not needed for anything other than low-level
hardware debugging.

mpe: It also introduces a large and poorly documented/understood
attack surface. Although the interface is only available to root, the
kernel still aspires to restrict root to accessing hardware through
well defined interfaces, which this is not.

opal-prd uses its own interface (/dev/prd) for SCOM access, so it
doesn't need SCOM_DEBUGFS.

At some point in the future we'll introduce a debug config fragment
where this can go instead.

Krzysztof Kozlowski 14b2f7d908 powerpc/configs: Remove useless UEVENT_HELPER_PATH
Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a57 ("driver: base: Disable
   CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
   made default to 'n',
2. It is not recommended (help message: "This should not be used today
   [...] creates a high system load") and was kept only for ancient
   userland,
3. Certain userland specifically requests it to be disabled (systemd

Nicholas Piggin 9a018fb1e1 powerpc/config: powernv_defconfig updates
For consideration:

* Add NVDIMM support - Enables greater testing, mambo device.
* Add IPv6 support built in + additional modules - Because it's 2018 maan.
* Add DEFERRED_STRUCT_PAGE_INIT - Let's see what breaks.
* Add PPC_MEMTRACE - Small powernv debugfs driver for getting hardware traces.
* Add MEMORY_FAILURE - Machine check exceptions can now drive memory failure.
* Turn on FANOTIFY - This is the current filesystem notification feature.
* Turn on SCOM_DEBUGFS - Handy for hardware/firmware debugging, security risk?
* Turn on async SCSI scanning - Let's see what breaks.
* Add MLX5 driver as a module - Popular demand.
* Add CRYPTO_CRCT10DIF_VPMSUM - POWER8 T10DIF acceleration.

* Make a bunch of USB hid drivers modules.
* Make SCSI SG, SR, and FC modules - FC is huge.
* Make video drivers except AST GPU modules - Also huge.
* Make PCI serial driver a module - Uncommon.
* Make more things modules, NFS FS, RAM disk, netconsole, MS-DOS fs.

* Get rid of /dev/port - Not used.
* Remove PPS and PTP subsystms - Unusual.
* Remove legacy BSD ttys - Long dead.
* Remove IDE - Deprecated and replaced with ATA.
* Remove WIRELESS - Until we get POWER9 laptops.
* Remove RAW - Long deprecated in favour of direct IO.
* Remove floppy, parport, and PS2 input devices - not supported.
* Remove virtio drivers, ballooning - We're host only.
* Remove PPP - Sorry Paulus.

This results in a significantly smaller vmlinux:

Linus Torvalds 03f51d4efa powerpc updates for 4.16
Highlights:
 
  - Enable support for memory protection keys aka "pkeys" on Power7/8/9 when
    using the hash table MMU.
 
  - Extend our interrupt soft masking to support masking PMU interrupts as well
    as "normal" interrupts, and then use that to implement local_t for a ~4x
    speedup vs the current atomics-based implementation.
 
  - A new driver "ocxl" for "Open Coherent Accelerator Processor Interface
    (OpenCAPI)" devices.
 
  - Support for new device tree properties on PowerVM to describe hotpluggable
    memory and devices.
 
  - Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 64-bit VDSO.
 
  - Freescale updates from Scott:
      "Contains fixes for CPM GPIO and an FSL PCI erratum workaround, plus a
       minor cleanup patch."
 
 As well as quite a lot of other changes all over the place, and small fixes and
 cleanups as always.

Michael Ellerman 7a53ef5ebe powerpc/configs: Drop REISERFS from pseries & powernv
No one uses reiserfs much these days, or is likely to in future. So drop
it from pseries and powernv defconfigs to save time and space. It's
still enabled in ppc64_defconfig so we get some build coverage.

Anton Blanchard d3eb34a312 powerpc/configs: Change a few things from built in to modules
Change a few devices and filesystems that are seldom used any more
from built in to modules. This reduces our vmlinux about 500kB.

Anton Blanchard 32eab6c9e1 powerpc/configs: Bump kernel ring buffer size on 64 bit configs
When we issue a system reset, every CPU in the box prints an Oops,
including a backtrace. Each of these can be quite large (over 4kB)
and we may end up wrapping the ring buffer and losing important
information.

Bump the base size from 128kB to 256kB and the per CPU size from
4kB to 8kB.

Suraj Jitindar Singh 43a1dd9b5f powerpc/powernv: Add driver for operator panel on FSP machines
Implement new character device driver to allow access from user space
to the operator panel display present on IBM Power Systems machines
with FSPs.

This will allow status information to be presented on the display which
is visible to a user.

The driver implements a character buffer which a user can read/write
by accessing the device (/dev/op_panel). This buffer is then displayed on
the operator panel display. Any attempt to write past the last character
position will have no effect and attempts to write more characters than
the size of the display will be truncated. The device may only be accessed
by a single process at a time.
