commit d4a5c59a955bba96b273ec1a5885bada24c56979 upstream.
au1xmmc is split somewhat awkwardly into the main mmc subsystem driver,
and callbacks in platform_data that sit under arch/mips/ and are
always built in. The latter than call mmc_detect_change through
symbol_get. Remove the use of symbol_get by requiring the driver
to be built in. In the future the interrupt handlers for card
insert/eject detection should probably be moved into the main driver,
and which point it can be built modular again.

Some CPU feature macros were using current_cpu_type to mark feature
availability.
However current_cpu_type will use smp_processor_id, which is prohibited
under preemptable context.
Since those features are all uniform on all CPUs in a SMP system, use
boot_cpu_type instead of current_cpu_type to fix preemptable kernel.

[ Upstream commit 531b3d1195d096f14e030c4b01ec3a53b80276bf ]
After commit 0e96ea5c3eb5904e5dc2f ("MIPS: Loongson64: Clean up use of
cc-ifversion") we get a build error when make modules_install:
cc1: error: '-mloongson-mmi' must be used with '-mhard-float'
The reason is when make modules_install, 'call cc-option' doesn't work
in $(KBUILD_CFLAGS) of 'CHECKFLAGS'. Then there is no -mno-loongson-mmi
applied and -march=loongson3a enable MMI instructions.
To be detail, the error message comes from the CHECKFLAGS invocation of
$(CC) but it has no impact on the final result of make modules_install,
it is purely a cosmetic issue. The error occurs because cc-option is
defined in scripts/Makefile.compiler, which is not included in Makefile
when running 'make modules_install', as install targets are not supposed
to require the compiler; see commit 805b2e1d427aab4b ("kbuild: include
Makefile.compiler only when compiler is needed"). As a result, the call
to check for '-mno-loongson-mmi' just never happens.
Fix this by partially reverting to the old logic, use 'call cc-option'
to conditionally apply -march=loongson3a and -march=mips64r2.
By the way, Loongson-2E/2F is also broken in commit 13ceb48bc19c563e05f4
("MIPS: Loongson2ef: Remove unnecessary {as,cc}-option calls") so fix it
together.

Commit 7db5e9e9e5e6c10d7d ("MIPS: loongson64: fix FTLB configuration")
move decode_configs() from the beginning of cpu_probe_loongson() to the
end in order to fix FTLB configuration. However, it breaks the CPUCFG
decoding because decode_configs() use "c->options = xxxx" rather than
"c->options |= xxxx", all information get from CPUCFG by decode_cpucfg()
is lost.
This causes error when creating a KVM guest on Loongson-3A4000:

This patch is for linux-6.1.y and earlier, it has no direct mainline
equivalent.
In order to backport commit d5c8d6e0fa61 ("kbuild: Update assembler
calls to use proper flags and language target") to resolve a separate
issue regarding PowerPC, the problem noticed and fixed by
commit 80a20d2f8288 ("MIPS: Always use -Wa,-msoft-float and eliminate
GAS_HAS_SET_HARDFLOAT") needs to be addressed. Unfortunately, 6.1 and
earlier do not contain commit e4412739472b ("Documentation: raise
minimum supported version of binutils to 2.25"), so it cannot be assumed
that all supported versions of GNU as have support for -msoft-float.
In order to switch from KBUILD_CFLAGS to KBUILD_AFLAGS in as-option
without consequence, move the '-Wa,-msoft-float' check to cc-option,
including '$(cflags-y)' directly to avoid the issue mentioned in
commit 80a20d2f8288 ("MIPS: Always use -Wa,-msoft-float and eliminate

early_init_dt_scan_memory the only way to initialize the memory.

initialization being done via the soc_info.mem_detect function

get_port_from_cmdline() returns an int, yet is assigned to a char, which
is wrong in its own right, but also, with char becoming unsigned, this
poses problems, because -1 is used as an error value. Further
complicating things, fw_init_early_console() is only ever called with a
-1 argument. Fix this up by removing the unused argument from
fw_init_early_console() and treating port as a proper signed integer.

Pull more random number generator updates from Jason Donenfeld:
"This time with some large scale treewide cleanups.
The intent of this pull is to clean up the way callers fetch random
integers. The current rules for doing this right are:
- If you want a secure or an insecure random u64, use get_random_u64()
- If you want a secure or an insecure random u32, use get_random_u32()
The old function prandom_u32() has been deprecated for a while
now and is just a wrapper around get_random_u32(). Same for
get_random_int().
- If you want a secure or an insecure random u16, use get_random_u16()
- If you want a secure or an insecure random u8, use get_random_u8()
- If you want secure or insecure random bytes, use get_random_bytes().
The old function prandom_bytes() has been deprecated for a while
now and has long been a wrapper around get_random_bytes()
- If you want a non-uniform random u32, u16, or u8 bounded by a
certain open interval maximum, use prandom_u32_max()
I say "non-uniform", because it doesn't do any rejection sampling
or divisions. Hence, it stays within the prandom_*() namespace, not
the get_random_*() namespace.
I'm currently investigating a "uniform" function for 6.2. We'll see
what comes of that.
By applying these rules uniformly, we get several benefits:
- By using prandom_u32_max() with an upper-bound that the compiler
can prove at compile-time is ≤65536 or ≤256, internally
get_random_u16() or get_random_u8() is used, which wastes fewer
batched random bytes, and hence has higher throughput.
- By using prandom_u32_max() instead of %, when the upper-bound is
not a constant, division is still avoided, because
prandom_u32_max() uses a faster multiplication-based trick instead.
- By using get_random_u16() or get_random_u8() in cases where the
return value is intended to indeed be a u16 or a u8, we waste fewer
batched random bytes, and hence have higher throughput.
This series was originally done by hand while I was on an airplane
without Internet. Later, Kees and I worked on retroactively figuring
out what could be done with Coccinelle and what had to be done
manually, and then we split things up based on that.
So while this touches a lot of files, the actual amount of code that's
hand fiddled is comfortably small"

- Remove potentially incomplete targets when Kbuid is interrupted by
SIGINT etc. in case GNU Make may miss to do that when stderr is piped
to another program.
- Rewrite the single target build so it works more correctly.
- Fix rpm-pkg builds with V=1.
- List top-level subdirectories in ./Kbuild.
- Ignore auto-generated __kstrtab_* and __kstrtabns_* symbols in kallsyms.
- Avoid two different modules in lib/zstd/ having shared code, which
potentially causes building the common code as build-in and modular
back-and-forth.
- Unify two modpost invocations to optimize the build process.
- Remove head-y syntax in favor of linker scripts for placing particular
sections in the head of vmlinux.
- Bump the minimal GNU Make version to 3.82.
- Clean up misc Makefiles and scripts.

am sending out early due to me travelling next week. There is a
lone mm patch for which Andrew gave an informal ack at
https://lore.kernel.org/linux-mm/20220817102500.440c6d0a3fce296fdf91bea6@linux-foundation.org.
I will send the bulk of ARM work, as well as other
architectures, at the end of next week.
ARM:
* Account stage2 page table allocations in memory stats.
x86:
* Account EPT/NPT arm64 page table allocations in memory stats.
* Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR accesses.
* Drop eVMCS controls filtering for KVM on Hyper-V, all known versions of
Hyper-V now support eVMCS fields associated with features that are
enumerated to the guest.
* Use KVM's sanitized VMCS config as the basis for the values of nested VMX
capabilities MSRs.
* A myriad event/exception fixes and cleanups. Most notably, pending
exceptions morph into VM-Exits earlier, as soon as the exception is
queued, instead of waiting until the next vmentry. This fixed
a longstanding issue where the exceptions would incorrecly become
double-faults instead of triggering a vmexit; the common case of
page-fault vmexits had a special workaround, but now it's fixed
for good.
* A handful of fixes for memory leaks in error paths.
* Cleanups for VMREAD trampoline and VMX's VM-Exit assembly flow.
* Never write to memory from non-sleepable kvm_vcpu_check_block()
* Selftests refinements and cleanups.
* Misc typo cleanups.
Generic:
* remove KVM_REQ_UNHALT

Here is the large set of char/misc and other small driver subsystem
changes for 6.1-rc1. Loads of different things in here:
- IIO driver updates, additions, and changes. Probably the largest
part of the diffstat
- habanalabs driver update with support for new hardware and features,
the second largest part of the diff.
- fpga subsystem driver updates and additions
- mhi subsystem updates
- Coresight driver updates
- gnss subsystem updates
- extcon driver updates
- icc subsystem updates
- fsi subsystem updates
- nvmem subsystem and driver updates
- misc driver updates
- speakup driver additions for new features
- lots of tiny driver updates and cleanups
All of these have been in the linux-next tree for a while with no
reported issues.
