This reverts
1fdbe0b184 bcachefs: Make sure c->vfs_sb is set before starting fs
switched up bch2_fs_get_tree() so that we got a superblock before
calling bch2_fs_start, so that c->vfs_sb would always be initialized
while the filesystem was active.
This turned out not to be necessary, because blk_holder_ops were
implemented using our own locking, not vfs locking.
And this had the side effect of creating a super_block and doing our
full recovery (including potentially fsck) before setting SB_BORN, which
causes things like sync calls to hang until our recovery is finished.

We keep setting and clearing these bits depending on the role of
the host kernel, mimicking what we do for nVHE. But that's actually
pretty pointless, as we always want physical interrupts to make it
to the host, at EL2.
This has also two problems:
- it prevents IRQs from being taken when these bits are cleared
if the implementation has chosen to implement these bits as
masks when HCR_EL2.{TGE,xMO}=={0,0}
- it triggers a bad erratum on the AmpereOne HW, which catches
fire on clearing these bits while an interrupt is being taken
(AC03_CPU_36).
Let's kill these two birds with a single stone, and permanently
set the xMO bits when running VHE. This involves a bit of surgery
on code paths that rely on flipping these bits on and off for
other purposes.
Note that the earliest setting of hcr_el2 (in the init_hcr_el2
macro) is left untouched as is runs extremely early, with interrupts
disabled, and soon enough overwritten with the final value containing
the xMO bits.

There was a buggy version of bcachefs-tools which picked misaligned
bucket sizes when formatting, and we're also about to do dynamic block
sizes - which will allow picking logical block size or physical block
size of the device per-write, allowing for better compression ratios at
the cost of slightly worse write performance (i.e. forcing the device to
do RMW or extra buffering).
To account for this, tweak bch2_alloc_sectors_start() to properly align
open_buckets to the blocksize of the write we're about to do.

Event polling delay is set to 0 if there are any pending requests in

not work well for "IN" transfers as the tty driver always queues
requests to the list and TRBs to the ring, preparing to receive data
from the host.
This causes unnecessary busylooping and cpu hogging.
Only set the event polling delay to 0 if there are pending tx "write"
transfers, or if it was less than 10ms since last active data transfer
in any direction.

VIA VL805 doesn't bother updating the EP Context cycle bit when the
endpoint halts. This is seen by patching xhci_move_dequeue_past_td()
to print the cycle bits of the EP Context and the TRB at hw_dequeue
and then disconnecting a flash drive while reading it. Actual cycle
state is random as expected, but the EP Context bit is always 1.
This means that the cycle state produced by this function is wrong
half the time, and then the endpoint stops working.
Work around it by looking at the cycle bit of TD's end_trb instead
of believing the Endpoint or Stream Context. Specifically:
- rename cycle_found to hw_dequeue_found to avoid confusion
- initialize new_cycle from td->end_trb instead of hw_dequeue
- switch new_cycle toggling to happen after end_trb is found
Now a workload which regularly stalls the device works normally for
a few hours and clearly demonstrates the HW bug - the EP Context bit
is not updated in a new cycle until Set TR Dequeue overwrites it:
[ +0,000298] sd 10:0:0:0: [sdc] Attached SCSI disk
[ +0,011758] cycle bits: TRB 1 EP Ctx 1
[ +5,947138] cycle bits: TRB 1 EP Ctx 1
[ +0,065731] cycle bits: TRB 0 EP Ctx 1
[ +0,064022] cycle bits: TRB 0 EP Ctx 0

[ +0,069823] cycle bits: TRB 0 EP Ctx 0
[ +0,063390] cycle bits: TRB 1 EP Ctx 0
[ +0,063064] cycle bits: TRB 1 EP Ctx 1
[ +0,062293] cycle bits: TRB 1 EP Ctx 1
[ +0,066087] cycle bits: TRB 0 EP Ctx 1
[ +0,063636] cycle bits: TRB 0 EP Ctx 0
[ +0,066360] cycle bits: TRB 0 EP Ctx 0
Also tested on the buggy ASM1042 which moves EP Context dequeue to
the next TRB after errors, one problem case addressed by the rework
that implemented this loop. In this case hw_dequeue can be enqueue,
so simply picking the cycle bit of TRB at hw_dequeue wouldn't work.
Commit 5255660b20 ("xhci: add quirk for host controllers that
don't update endpoint DCS") tried to solve the stale cycle problem,
but it was more complex and got reverted due to a reported issue.

After commit 653d7825c1 ("dcssblk: mark DAX broken, remove FS_DAX_LIMITED
support") moved the "select DAX" from config DCSSBLK to the new config
DCSSBLK_DAX, randconfig tests could result in build errors like this:

s390-linux-ld: drivers/s390/block/dcssblk.c:418: undefined reference to `put_dax'
This is because it's now possible to have CONFIG_DCSSBLK=y, but CONFIG_DAX=m.
Fix this by adding "depends on DAX || DAX=n" to config DCSSBLK, to make it
explicit that we want either no DAX, or the same "y/m" for both config DAX
and DCSSBLK, similar to config BLK_DEV_DM.
This also requires removing the "select DAX" from config DCSSBLK_DAX, or
else there would be a recursive dependency detected. DCSSBLK_DAX is marked
as BROKEN at the moment, and won't work well with DAX anyway, so it doesn't
really matter if it is selected.

On x86 during boot, clockevent_i8253_disable() can be invoked via

with enabled interrupts.
If some of the old i8253 hardware is actually used then lockdep will notice
that i8253_lock is used in hard interrupt context. This causes lockdep to
complain because it observed the lock being acquired with interrupts
enabled and in hard interrupt context.
Make clockevent_i8253_disable() acquire the lock with

Consolidate the whole logic which determines whether the microcode loader
should be enabled or not into a single function and call it everywhere.
Well, almost everywhere - not in mk_early_pgtbl_32() because there the kernel
is running without paging enabled and checking dis_ucode_ldr et al would
require physical addresses and uglification of the code.
But since this is 32-bit, the easier thing to do is to simply map the initrd
unconditionally especially since that mapping is getting removed later anyway
by zap_early_initrd_mapping() and avoid the uglification.
In doing so, address the issue of old 486er machines without CPUID
support, not booting current kernels.

Nathan reported [1] that when built with clang, the um kernel
crashes pretty much immediately. This turned out to be an issue
with the inline assembly I had added, when clang used %rax/%eax
for both operands. Reorder it so current->thread.segv_continue
is written first, and then the lifetime of _faulted won't have
overlap with the lifetime of segv_continue.
In the email thread Benjamin also pointed out that current->mm
is only NULL for true kernel tasks, but we could do this for a
userspace task, so the current->thread.segv_continue logic must
be lifted out of the mm==NULL check.
Finally, while looking at this, put a barrier() so the NULL
assignment to thread.segv_continue cannot be reorder before
the possibly faulting operation.

- Fix read out of bounds bug in tracing_splice_read_pipe()
The size of the sub page being read can now be greater than a page.
But the buffer used in tracing_splice_read_pipe() only allocates a
page size. The data copied to the buffer is the amount in sub buffer
which can overflow the buffer.
Use min((size_t)trace_seq_used(&iter->seq), PAGE_SIZE) to limit the
amount copied to the buffer to a max of PAGE_SIZE.
- Fix the test for NULL from "!filter_hash" to "!*filter_hash"
The add_next_hash() function checked for NULL at the wrong pointer
level.
- Do not use the array in trace_adjust_address() if there are no
elements
The trace_adjust_address() finds the offset of a module that was
stored in the persistent buffer when reading the previous boot buffer
to see if the address belongs to a module that was loaded in the
previous boot. An array is created that matches currently loaded
modules with previously loaded modules. The trace_adjust_address()
uses that array to find the new offset of the address that's in the
previous buffer. But if no module was loaded, it ends up reading the
last element in an array that was never allocated.
Check if nr_entries is zero and exit out early if it is.
- Remove nested lock of trace_event_sem in print_event_fields()

Camm noticed that on parisc a SIGFPE exception will crash an application with
a second SIGFPE in the signal handler. Dave analyzed it, and it happens
because glibc uses a double-word floating-point store to atomically update
function descriptors. As a result of lazy binding, we hit a floating-point
store in fpe_func almost immediately.
When the T bit is set, an assist exception trap occurs when when the
co-processor encounters *any* floating-point instruction except for a double
store of register %fr0. The latter cancels all pending traps. Let's fix this
by clearing the Trap (T) bit in the FP status register before returning to the
signal handler in userspace.
The issue can be reproduced with this test program:

provided a fix for SEV-SNP memory acceptance from the EFI stub when
running at VMPL #0. However, that fix was insufficient for SVSM SEV-SNP
guests running at VMPL >0, as those rely on a SVSM calling area, which
is a shared buffer whose address is programmed into a SEV-SNP MSR, and
the SEV init code that sets up this calling area executes much later
during the boot.
Given that booting via the EFI stub at VMPL >0 implies that the firmware
has configured this calling area already, reuse it for performing memory
acceptance in the EFI stub.

"These fix three recent regressions, two in cpufreq and one in the
Intel Soundwire driver, and an unchecked MSR access in the
intel_pstate driver:
- Fix a recent regression causing systems where frequency tables are
used by cpufreq to have issues with setting frequency limits
(Rafael Wysocki)
- Fix a recent regressions causing frequency boost settings to become
out-of-sync if platform firmware updates the registers associated
with frequency boost during system resume (Viresh Kumar)
- Fix a recent regression causing resume failures to occur in the
Intel Soundwire driver if the device handled by it is in runtime
suspend before a system-wide suspend (Rafael Wysocki)
- Fix an unchecked MSR aceess in the intel_pstate driver occurring
when CPUID indicates no turbo, but the driver attempts to enable
turbo frequencies due to a misleading value read from an MSR

When changing memory attributes on a subset of a potential hugepage, add
the hugepage to the invalidation range tracking to prevent installing a
hugepage until the attributes are fully updated. Like the actual hugepage
tracking updates in kvm_arch_post_set_memory_attributes(), process only
the head and tail pages, as any potential hugepages that are entirely
covered by the range will already be tracked.
Note, only hugepage chunks whose current attributes are NOT mixed need to
be added to the invalidation set, as mixed attributes already prevent
installing a hugepage, and it's perfectly safe to install a smaller
mapping for a gfn whose attributes aren't changing.

When a CL/CSD job times out, we check if the GPU has made any progress
since the last timeout. If so, instead of resetting the hardware, we skip
the reset and let the timer get rearmed. This gives long-running jobs a
chance to complete.
However, when `timedout_job()` is called, the job in question is removed
from the pending list, which means it won't be automatically freed through
`free_job()`. Consequently, when we skip the reset and keep the job
running, the job won't be freed when it finally completes.
This situation leads to a memory leak, as exposed in [1] and [2].
Similarly to commit 704d3d60fe ("drm/etnaviv: don't block scheduler when
GPU is still active"), this patch ensures the job is put back on the
pending list when extending the timeout.

On Qualcomm chipsets not all GPIOs are wakeup capable. Those GPIOs do not
have a corresponding MPM pin and should not be handled inside the MPM
driver. The IRQ domain hierarchy is always applied, so it's required to
explicitly disconnect the hierarchy for those. The pinctrl-msm driver marks
these with GPIO_NO_WAKE_IRQ. qcom-pdc has a check for this, but
irq-qcom-mpm is currently missing the check. This is causing crashes when
setting up interrupts for non-wake GPIOs:
root@rb1:~# gpiomon -c gpiochip1 10
irq: IRQ159: trimming hierarchy from :soc@0:interrupt-controller@f200000-1
Unable to handle kernel paging request at virtual address ffff8000a1dc3820
Hardware name: Qualcomm Technologies, Inc. Robotics RB1 (DT)
pc : mpm_set_type+0x80/0xcc

gpio_ioctl+0x2d4/0x6c0
Fix this by copying the check for GPIO_NO_WAKE_IRQ from qcom-pdc.c, so that
MPM is removed entirely from the hierarchy for non-wake GPIOs.
