Since multi_v7_defconfig is meant to be the generic defconfig, many
users are not going to be experts and it is counterintuitive to have
CONFIG_EXPERT enabled.
This change has a couple of side-effects:
- CONFIG_NAMESPACES is enabled by default. This adds about 0.2% of
.text, but is already enabled in many board specific configs, and
apparently a requirement for systemd, so this seems like a useful
change.
- CONFIG_DEBUG_MEMORY_INIT is enabled now, adding a tiny bit
of code in the inittext section
- CONFIG_RFKILL, CONFIG_MEDIA_SUPPORT_FILTER and various CONFIG_HID
driver defaults change, so these have to be listed explicitly to
maintain the previous behavior
- CONFIG_SERIAL_SH_SCI_NR_UARTS=20 changes to the default value
of 18, which I understand to be sufficient for any buard, even
if all UARTS are enabled at the same time

The i.MX ARM v4/v5 defconfig has gone out of sync with some dead options,
some removed and some missing.
1. Add missing options no longer enabled by default:
- CONFIG_I2C=y
- CONFIG_LCD_CLASS_DEVICE=y
2. Remove options enabled by default:
- CONFIG_CS89x0=y
- CONFIG_MEDIA_CAMERA_SUPPORT=y
3. Remove options that have no effect:
- # CONFIG_INET_XFRM_MODE_TRANSPORT is not set
- # CONFIG_INET_XFRM_MODE_TUNNEL is not set
- # CONFIG_INET_XFRM_MODE_BEET is not set
4. Remove options that have been removed completely from the kernel:
- CONFIG_USB_EHCI_MXC=y
Removed by commit e7018751d2 ("usb: host: ehci-mxc: Remove the
driver").
- CONFIG_SMC911X=y
Removed by commit a2fd08448f ("net: remove smc911x driver").
- -CONFIG_SND_SOC_MX27VIS_AIC32X4=y
Removed by commit 3fbb01fb58 ("ASoC: mx27vis-aic32x4: Remove unused
driver").
- CONFIG_SND_SOC_PHYCORE_AC97=y
Removed by commit 440534a0ec ("ASoC: phycore-ac97: Remove unused

- CONFIG_SND_SOC_IMX_MC13783=y

Enable drivers for hardware present on Apple Silicon machines. None of
these drivers are critical so build them as modules. The reset and RTC
macsmc drivers would be useful as built-in drivers but they have large
dependencies so keep them as modules.
The size increases are minor and are offsetted by already merged
"default ARCH_APPLE" removals from the linked original submission.

This option explicitly selects other options, e.g. SND_SOC_FSL_SAI.
These SAI drivers use DMA which in turn is dependent on CONFIG_IMX_SDMA.
SDMA needs a firmware which is not yet present if the driver is built-in.
Thus build CONFIG_SND_SOC_FSL_ASOC_CARD to avoid useless driver probe
deferrals due to missing DMA channels.

Merge tag 'riscv-for-linus-6.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V updates from Paul Walmsley:
"Nothing exotic here; these are the cleanup and new ISA extension
probing patches (not including CFI):
- Add probing and userspace reporting support for the standard RISC-V
ISA extensions Zilsd and Zclsd, which implement load/store dual
instructions on RV32
- Abstract the register saving code in setup_sigcontext() so it can
be used for stateful RISC-V ISA extensions beyond the vector
extension
- Add the SBI extension ID and some initial data structure
definitions for the RISC-V standard SBI debug trigger extension
- Clean up some code slightly: change some page table functions to
avoid atomic operations oinn !SMP and to avoid unnecessary casts to
atomic_long_t; and use the existing RISCV_FULL_BARRIER macro in
place of some open-coded 'fence rw,rw' instructions"
* tag 'riscv-for-linus-6.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:

__io_openat_prep() allocates a struct filename using getname(). However,
for the condition of the file being installed in the fixed file table as
well as having O_CLOEXEC flag set, the function returns early. At that
point, the request doesn't have REQ_F_NEED_CLEANUP flag set. Due to this,
the memory for the newly allocated struct filename is not cleaned up,
causing a memory leak.
Fix this by setting the REQ_F_NEED_CLEANUP for the request just after the
successful getname() call, so that when the request is torn down, the
filename will be cleaned up, along with other resources needing cleanup.

Add a WARN_ON_ONCE() check to detect mm_struct instances that are
missing user_ns initialization when passed to kthread_use_mm().
When a kthread adopts an mm via kthread_use_mm(), LSM hooks and
capability checks may access current->mm->user_ns for credential
validation. If user_ns is NULL, this leads to a NULL pointer
dereference crash.
This was observed with efi_mm on arm64, where commit a5baf582f4
("arm64/efi: Call EFI runtime services without disabling preemption")
introduced kthread_use_mm(&efi_mm), but efi_mm lacked user_ns
initialization, causing crashes during /proc access.
Adding this warning helps catch similar bugs early during development
rather than waiting for hard-to-debug NULL pointer crashes in
production.

Linux 6.19-rc2 (9448598b22 ("Linux 6.19-rc2")) is crashing with a NULL
pointer dereference on arm64 hosts:

I've bissected the problem to commit a5baf582f4 ("arm64/efi: Call EFI
runtime services without disabling preemption").
>From my analyzes, the crash occurs because efi_mm lacks a user_ns field
initialization. This was previously harmless, but commit a5baf582f4
("arm64/efi: Call EFI runtime services without disabling preemption")
changed the EFI runtime call path to use kthread_use_mm(&efi_mm), which
temporarily adopts efi_mm as the current mm for the calling kthread.
When a thread has an active mm, LSM hooks like cap_capable() expect
mm->user_ns to be valid for credential checks. With efi_mm.user_ns being
NULL, capability checks during possible /proc access dereference the
NULL pointer and crash.
Fix by initializing efi_mm.user_ns to &init_user_ns.

The efi_edid_discovered_protocol and efi_edid_active_protocol have mixed
mode fields. So all their attributes should be accessed through
the efi_table_attr() helper.
Doing so fixes the upper 32 bits of the 64 bit gop_edid pointer getting
set to random values (followed by a crash at boot) when booting a x86_64
kernel on a machine with 32 bit UEFI like the Asus T100TA.

Pull erofs fix from Gao Xiang:
"Junbeom reported that synchronous reads could hit unintended EIOs
under memory pressure due to incorrect error propagation in
z_erofs_decompress_queue(), where earlier physical clusters in the
same decompression queue may be served for another readahead.
This addresses the issue by decompressing each physical cluster
independently as long as disk I/Os succeed, rather than being impacted
by the error status of previous physical clusters in the same queue.
Summary:
- Fix unexpected EIOs under memory pressure caused by recent
incorrect error propagation logic"

erofs: fix unexpected EIO under memory pressure
In smb3_reconfigure(), if smb3_sync_session_ctx_passwords() fails, the
function returns immediately without freeing and erasing the newly
allocated new_password and new_password2. This causes both a memory leak
and a potential information leak.
Fix this by calling kfree_sensitive() on both password buffers before
returning in this error case.

The refill_buf function uses snprintf to append to a fixed-size buffer.
snprintf returns the length that would have been written, which can
exceed the remaining buffer size. If this happens, ptr advances beyond
the buffer and rem becomes negative. In the 2nd iteration, rem is
treated as a large unsigned integer, causing snprintf to write oob.
While this behavior is technically mitigated by num_perfcntrs being
locked at 5, it's still unsafe if num_perfcntrs were ever to change/a
second source was added.
