The crazy gic_arch_extn thing that Tegra uses contains multiple
references to the irq field in struct irq_data, and uses this
to directly poke hardware register.
But irq is the *virtual* irq number, something that has nothing
to do with the actual HW irq (stored in the hwirq field). And once
we put the stacked domain code in action, the whole thing explodes,
as these two values are *very* different:
root@bacon-fat:~# cat /proc/interrupts
CPU0 CPU1
16: 25801 2075 GIC 29 twd
17: 0 0 GIC 73 timer0
112: 0 0 GPIO 58 c8000600.sdhci cd

284: 300 0 GIC 85 7000d000.i2c
[...]
Just replacing all instances of irq with hwirq fixes the issue.

The flag passed to ioda_eeh_phb_reset() should be EEH_RESET_DEACTIVATE,
which is translated to OPAL_DEASSERT_RESET or something else by the
EEH backend accordingly.
The patch replaces OPAL_DEASSERT_RESET with EEH_RESET_DEACTIVATE for
ioda_eeh_phb_reset().

On pseries system (LPAR) xmon failed to enter when running in LE mode,

The root cause is that xmon is calling RTAS to turn off the surveillance

This patch is byte swapping the RTAS arguments when running in LE mode.

The current HMI event structure is an ABI and carries a version field to
accommodate future changes without affecting/rearranging current structure
members that are valid for previous versions.
The current version check "if (hmi_evt->version != OpalHMIEvt_V1)"
doesn't accomodate the fact that the version number may change in
future.
If firmware starts returning an HMI event with version > 1, this check
will fail and no HMI information will be printed on older kernels.
This patch fixes this issue.

The head.text section is intended to be run at early bootup
before any of the regular kernel mappings have been setup.
Parts of head.text may be freed back into the buddy allocator
due to TEXT_OFFSET so for security requirements this memory
must not be executable. The suspend/resume/hotplug code path
requires some of these head.S functions to run however which
means they need to be executable. Support these conflicting
requirements by moving the few head.text functions that need
to be executable to the text section which has the appropriate
page table permissions.

In the arm64 arch_static_branch implementation we place an A64 NOP into
the instruction stream and log relevant details to a jump_entry in a
__jump_table section. Later this may be replaced with an immediate
branch without link to the code for the unlikely case.
At init time, the core calls arch_jump_label_transform_static to
initialise the NOPs. On x86 this involves inserting the optimal NOP for
a given microarchitecture, but on arm64 we only use the architectural
NOP, and hence replace each NOP with the exact same NOP. This is
somewhat pointless.
Additionally, at module load time we don't call jump_label_apply_nops to
patch the optimal NOPs in, unlike other architectures, but get away with
this because we only use the architectural NOP anyway. A later notifier
will patch NOPs with branches as required.
Similarly to x86 commit 11570da1c5b1dee1 (x86/jump-label: Do not bother
updating NOPs if they are correct), we can avoid patching NOPs with
identical NOPs. Given that we only use a single NOP encoding, this means
we can NOP-out the body of arch_jump_label_transform_static entirely. As
the default __weak arch_jump_label_transform_static implementation
performs a patch, we must use an empty function to achieve this.

As USE_OF is now selected directly in arch/arm/Kconfig AT91 entry, we can
safely remove it everywhere in this file.

This reverts commit 85c8555ff0 ("KVM: check for !is_zero_pfn() in
kvm_is_mmio_pfn()") and renames the function to kvm_is_reserved_pfn.
The problem being addressed by the patch above was that some ARM code
based the memory mapping attributes of a pfn on the return value of
kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should
be mapped as device memory.
However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin,
and the existing non-ARM users were already using it in a way which
suggests that its name should probably have been 'kvm_is_reserved_pfn'
from the beginning, e.g., whether or not to call get_page/put_page on
it etc. This means that returning false for the zero page is a mistake
and the patch above should be reverted.

Instead of using kvm_is_mmio_pfn() to decide whether a host region
should be stage 2 mapped with device attributes, add a new static
function kvm_is_device_pfn() that disregards RAM pages with the
reserved bit set, as those should usually not be mapped as device
memory.

When running on a system with a GICv3, we currenly don't allow the guest
to access the system register interface of the GICv3. We do this by
clearing the ICC_SRE_EL2.Enable, which causes all guest accesses to
ICC_SRE_EL1 to trap to EL2 and causes all guest accesses to other ICC_
registers to cause an undefined exception in the guest.
However, we currently don't handle the trap of guest accesses to
ICC_SRE_EL1 and will spill out a warning. The trap just needs to handle
the access as RAZ/WI, and a guest that tries to prod this register and
set ICC_SRE_EL1.SRE=1, must read back the value (which Linux already
does) to see if it succeeded, and will thus observe that ICC_SRE_EL1.SRE
was not set.
Add the simple trap handler in the sorted table of the system registers.

Currently if using a 48-bit VA, tearing down the hyp page tables (which
can happen in the absence of a GICH or GICV resource) results in the
rather nasty splat below, evidently becasue we access a table that
doesn't actually exist.
Commit 38f791a4e499792e (arm64: KVM: Implement 48 VA support for KVM EL2
and Stage-2) added a pgd_none check to __create_hyp_mappings to account
for the additional level of tables, but didn't add a corresponding check
to unmap_range, and this seems to be the source of the problem.
This patch adds the missing pgd_none check, ensuring we don't try to
access tables that don't exist.

omap_hsmmc supports only one slot per controller, see OMAP_MMC_MAX_SLOTS.
This unnecessary indirection leads to confusion in the omap_hsmmc driver.
For example the card_detect callback is not installed by platform code
but from the driver probe function. So it should be a field of
omap_hsmmc_host. But since it is declared under the platform slot while
the drivers struct omap_hsmmc_host has no slot abstraction, this looks
like a bug, especially when not familiar that this driver only supports
1 slot anyway.
Either we should add a slot abstraction to omap_hsmmc_host or remove
it from the platform data struct. Removed since slot multiplexing is
an un-implemented feature

platform data is built from omap2_hsmmc_info, remove all fields that
are never set in omap_hsmmc_info, hence never copied to platform data.

- omap mmc driver supports multiplexing, omap_mmc_hs doesn't
this leads to one of the major confusions in the omap_hsmmc driver
- platform data should be read-only for the driver
most callbacks are not set by the omap3 platform init code while still
required. So they are set from the driver probe function, which is against
the paradigm that platform-data should not be modified by the driver
typical examples are card_detect, read_only callbacks
un-bundling by searching for driver name \"omap_hsmmc in the
arch/arm folder. omap_hsmmc_platform_data is not initialized directly,
but from omap2_hsmmc_info, which is defined in a separate header file
not touched by this patch
hwmod includes platform headers to declare features of the platform. All
the declared features are prefixed OMAP_HSMMC. There is no need to
include platform header from hwmod other except for feature defines

Only a few files really need that platform header. When later splitting
omap_mmc_platform_data into omap_mmc and omap_mmc_hs, those files
declaring an hs mmc platform data will have to change the platform
include, which is a good sanity check.
Also removing omap242x_init_mmc, which is not used anywhere, checked
with grep.

This adds the module loading prefix "crypto-" to the template lookup

For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly
includes the "crypto-" prefix at every level, correctly rejecting "vfat":

Every other architecture with permanent fixed addresses has
FIX_HOLE as the first entry. This seems to be designed as a
debugging aid but there are a couple of side effects of not
having FIX_HOLE:
- If the first fixed address is 0, fix_to_virt -> virt_to_fix
triggers a BUG_ON for the virtual address being equal to
FIXADDR_TOP
- fix_to_virt may return a value outside of FIXADDR_START
and FIXADDR_TOP which may look like a bug to a developer.
Match up with other architectures and make everything clearer
by adding FIX_HOLE.

$ grep pmx arch/arm/boot/dts/armada-*.dts* | wc -l

struct bfin_serial_port contains structs circ_buf, timer_list, and
work_struct directly (not pointers). This means that these structures
have to be defined completely to be inlined in struct
bfin_serial_port.
So instead of struct declarations, define the structures by including
proper headers. They were pulled in by linux/serial_core.h or others
until now. But experimenting with circ_buf removal from serial_core,
struct circ_buf becomes undefined in bfin_serial:
