634cd4b6af Merge branch 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI updates from Ingo Molnar:
 "The main changes in this cycle were:

   - Cleanup of the GOP [graphics output] handling code in the EFI stub

   - Complete refactoring of the mixed mode handling in the x86 EFI stub

   - Overhaul of the x86 EFI boot/runtime code

   - Increase robustness for mixed mode code

   - Add the ability to disable DMA at the root port level in the EFI
     stub

   - Get rid of RWX mappings in the EFI memory map and page tables,
     where possible

   - Move the support code for the old EFI memory mapping style into its
     only user, the SGI UV1+ support code.

   - plus misc fixes, updates, smaller cleanups.

  ... and due to interactions with the RWX changes, another round of PAT
  cleanups make a guest appearance via the EFI tree - with no side
  effects intended"

3d3b44a61a The interrupt departement provides:
- A mechanism to shield isolated tasks from managed interrupts:
 
    The affinity of managed interrupts is completely controlled by the
    kernel and user space has no influence on them. The reason is that
    the automatically assigned affinity correlates to the multi-queue
    CPU handling of block devices.
 
    If the generated affinity mask spaws both housekeeping and isolated CPUs
    the interrupt could be routed to an isolated CPU which would then be
    disturbed by I/O submitted by a housekeeping CPU.
 
    The new mechamism ensures that as long as one housekeeping CPU is online
    in the assigned affinity mask the interrupt is routed to a housekeeping
    CPU.
 
    If there is no online housekeeping CPU in the affinity mask, then the
    interrupt is routed to an isolated CPU to keep the device queue intact,
    but unless the isolated CPU submits I/O by itself these interrupts are
    not raised.
 
  - A small addon to the device tree irqdomain core code to avoid
    duplication in irq chip drivers
 
  - Conversion of the SiFive PLIC to hierarchical domains
 
  - The usual pile of new irq chip drivers: SiFive GPIO, Aspeed SCI, NXP
    INTMUX, Meson A1 GPIO
 
  - The first cut of support for the new ARM GICv4.1
 
  - The usual pile of fixes and improvements in core and driver code

e279160f49 The timekeeping and timers departement provides:
- Time namespace support:
 
     If a container migrates from one host to another then it expects that
     clocks based on MONOTONIC and BOOTTIME are not subject to
     disruption. Due to different boot time and non-suspended runtime these
     clocks can differ significantly on two hosts, in the worst case time
     goes backwards which is a violation of the POSIX requirements.
 
     The time namespace addresses this problem. It allows to set offsets for
     clock MONOTONIC and BOOTTIME once after creation and before tasks are
     associated with the namespace. These offsets are taken into account by
     timers and timekeeping including the VDSO.
 
     Offsets for wall clock based clocks (REALTIME/TAI) are not provided by
     this mechanism. While in theory possible, the overhead and code
     complexity would be immense and not justified by the esoteric potential
     use cases which were discussed at Plumbers '18.
 
     The overhead for tasks in the root namespace (host time offsets = 0) is
     in the noise and great effort was made to ensure that especially in the
     VDSO. If time namespace is disabled in the kernel configuration the
     code is compiled out.
 
     Kudos to Andrei Vagin and Dmitry Sofanov who implemented this feature
     and kept on for more than a year addressing review comments, finding
     better solutions. A pleasant experience.
 
   - Overhaul of the alarmtimer device dependency handling to ensure that
     the init/suspend/resume ordering is correct.
 
   - A new clocksource/event driver for Microchip PIT64
 
   - Suspend/resume support for the Hyper-V clocksource
 
   - The usual pile of fixes, updates and improvements mostly in the
     driver code.

a56c41e5d7 Two fixes for the generic VDSO code which missed 5.5:
- Make the update to the coarse timekeeper unconditional. This is required
    because the coarse timekeeper interfaces in the VDSO do not depend on a
    VDSO capable clocksource. If the system does not have a VDSO capable
    clocksource and the update is depending on the VDSO capable clocksource,
    the coarse VDSO interfaces would operate on stale data forever.
 
  - Invert the logic of __arch_update_vdso_data() to avoid further head
    scratching. Tripped over this several times while analyzing the update
    problem above.

6716cb162d Few minor fixes for omaps
Looks like we have wrong default memory size for beaglebone black,
 it has at least 512 MB of RAM and not 256 MB. This causes an issue
 when booted with GRUB2 that does not seem to pass memory info to
 the kernel.
 
 And for am43x-epos-evm the SPI pin directions need to be configured
 for SPI to work.

6849b5eba1 ARM: 8955/1: virt: Relax arch timer version check during early boot
Updates to the Generic Timer architecture allow ID_PFR1.GenTimer to
have values other than 0 or 1 while still preserving backward
compatibility. At the moment, Linux is quite strict in the way it
handles this field at early boot and will not configure arch timer if
it doesn't find the value 1.

Since here use ubfx for arch timer version extraction (hyb-stub build
with -march=armv7-a, so it is safe)

To help backports (even though the code was correct at the time of writing)

5e5168461c irqchip/gic-v4.1: VPE table (aka GICR_VPROPBASER) allocation
GICv4.1 defines a new VPE table that is potentially shared between
both the ITSs and the redistributors, following complicated affinity
rules.

To make things more confusing, the programming of this table at
the redistributor level is reusing the GICv4.0 GICR_VPROPBASER register
for something completely different.

The code flow is somewhat complexified by the need to respect the
affinities required by the HW, meaning that tables can either be
inherited from a previously discovered ITS or redistributor.

575966e080 ARM: SoC fixes
I've been sitting on these longer than I meant, so the patch count is
 a bit higher than ideal for this part of the release. There's also some
 reverts of double-applied patches that brings the diffstat up a bit.
 
 With that said, the biggest changes are:
 
  - Revert of duplicate i2c device addition on two Aspeed (BMC) Devicetrees.
  - Move of two device nodes that got applied to the wrong part of the
    tree on ASpeed G6.
  - Regulator fix for Beaglebone X15 (adding 12/5V supplies)
  - Use interrupts for keys on Amlogic SM1 to avoid missed polls
 
 In addition to that, there is a collection of smaller DT fixes:
 
  - Power supply assignment fixes for i.MX6
  - Fix of interrupt line for magnetometer on i.MX8 Librem5 devkit
  - Build fixlets (selects) for davinci/omap2+
  - More interrupt number fixes for Stratix10, Amlogic SM1, etc.
  - ... and more similar fixes across different platforms
 
 And some non-DT stuff:
 
  - optee fix to register multiple shared pages properly
  - Clock calculation fixes for MMP3
  - Clock fixes for OMAP as well

The EDIMM STARTER KIT i.Core 1.5 MIPI Evaluation is based on
the 1.5 version of the i.Core MX6 cpu module. The 1.5 version
differs from the original one for a few details, including the
ethernet PHY interface clock provider.

With this commit, the ethernet interface works properly:
SMSC LAN8710/LAN8720 2188000.ethernet-1:00: attached PHY driver

While before using the 1.5 version, ethernet failed to startup
do to un-clocked PHY interface:

Similar fix has merged for i.Core MX6Q but missed to update for DL.

966291f634 efi/libstub: Rename efi_call_early/_runtime macros to be more intuitive
The macros efi_call_early and efi_call_runtime are used to call EFI
boot services and runtime services, respectively. However, the naming
is confusing, given that the early vs runtime distinction may suggest
that these are used for calling the same set of services either early
or late (== at runtime), while in reality, the sets of services they
can be used with are completely disjoint, and efi_call_runtime is also
only usable in 'early' code.

So do a global sweep to replace all occurrences with efi_bs_call or
efi_rt_call, respectively, where BS and RT match the idiom used by
the UEFI spec to refer to boot time or runtime services.

While at it, use 'func' as the macro parameter name for the function
pointers, which is less likely to collide and cause weird build errors.

2fcdad2a80 efi/libstub: Get rid of 'sys_table_arg' macro parameter
The efi_call macros on ARM have a dependency on a variable 'sys_table_arg'
existing in the scope of the macro instantiation. Since this variable
always points to the same data structure, let's create a global getter
for it and use that instead.

Note that the use of a global variable with external linkage is avoided,
given the problems we had in the past with early processing of the GOT
tables.

While at it, drop the redundant casts in the efi_table_attr and
efi_call_proto macros.

Due to this explicit awareness of the bitness in the code, we do a
lot of casting even on generic code that is shared with other
architectures, where mixed mode does not even exist. This casting
leads to loss of coverage of type checking by the compiler, which
we should try to avoid.

So instead of distinguishing between 32-bit vs 64-bit, distinguish
between native vs mixed, and limit all the nasty casting and
pointer mangling to the code that actually deals with mixed mode.

58ec655a75 efi/libstub: Remove unused __efi_call_early() macro
The macro __efi_call_early() is defined by various architectures but
never used. Let's get rid of it.

fe6a6689d1 ARM: dts: imx6q-dhcom: Fix SGTL5000 VDDIO regulator connection
The SGTL5000 VDDIO is connected to the PMIC SW2 output, not to
a fixed 3V3 rail. Describe this correctly in the DT.
