28d11e4548 x86/fred: KVM: VMX: Always use FRED for IRQs when CONFIG_X86_FRED=y
Now that FRED provides C-code entry points for handling IRQs, use the
FRED infrastructure for forwarding IRQs even if FRED is fully
disabled, e.g. isn't supported in hardware. Avoiding the non-FRED
assembly trampolines into the IDT handlers for IRQs eliminates the
associated non-CFI indirect call (KVM performs a CALL by doing a
lookup on the IDT using the IRQ vector).

Keep NMIs on the legacy IDT path, as the FRED NMI entry code relies on
FRED's architectural behavior with respect to NMI blocking, i.e. doesn't
jump through the myriad hoops needed to deal with IRET "unexpectedly"
unmasking NMIs.  KVM's NMI path already makes a direct CALL to C-code,
i.e. isn't problematic for CFI.  KVM does make a short detour through
assembly code to build the stack frame, but the "FRED entry from KVM"
path does the same.

Force FRED for 64-bit kernels if KVM_INTEL is enabled, as the benefits of
eliminating the IRQ trampoline usage far outwieghts the code overhead for
FRED.

deed19b9b2 x86/fred: Play nice with invoking asm_fred_entry_from_kvm() on non-FRED hardware
Modify asm_fred_entry_from_kvm() to allow it to be invoked by KVM even
when FRED isn't fully enabled, e.g. when running with
CONFIG_X86_FRED=y on non-FRED hardware.  This will allow forcing KVM
to always use the FRED entry points for 64-bit kernels, which in turn
will eliminate a rather gross non-CFI indirect call that KVM uses to
trampoline IRQs by doing IDT lookups.

The point of asm_fred_entry_from_kvm() is to bridge between C
(vmx:handle_external_interrupt_irqoff()) and more C
(__fred_entry_from_kvm()) while changing the calling context to appear
like an interrupt (pt_regs). Making the whole thing bound by C ABI.

All that remains for non-FRED hardware is to restore RSP (to undo the
redzone and alignment). However the trivial change would result in
code like:

  push %rbp
  mov %rsp, %rbp

  sub $REDZONE, %rsp
  and $MASK, %rsp

  PUSH_AND_CLEAR_REGS
   push %rbp

  POP_REGS
   pop %rbp <-- *objtool fail*

  mov %rbp, %rsp
  pop %rbp
  ret

And this will confuse objtool something wicked -- it gets confused by
the extra pop %rbp, not realizing the push and pop preserve the value.

Rather than trying to each objtool about this, recognise that since
the code is bound by C ABI on both ends and interrupts are not allowed
to change pt_regs (only exceptions are) it is sufficient to PUSH_REGS
in order to create pt_regs, but there is no reason to POP_REGS --
provided the callee-saved registers are preserved.

So avoid clearing callee-saved regs and skip POP_REGS.

2d1435b742 x86/fred: Install system vector handlers even if FRED isn't fully enabled
Install the system vector IRQ handlers for FRED even if FRED isn't fully
enabled in hardware.  This will allow KVM to use the FRED IRQ path even
on non-FRED hardware, which in turn will eliminate a non-CFI indirect CALL
(KVM currently invokes the IRQ handler via an IDT lookup on the vector).

0e20f1f4c2 x86/hyperv: Clean up hv_do_hypercall()
What used to be a simple few instructions has turned into a giant mess
(for x86_64). Not only does it use static_branch wrong, it mixes it
with dynamic branches for no apparent reason.

Notably it uses static_branch through an out-of-line function call,
which completely defeats the purpose, since instead of a simple
JMP/NOP site, you get a CALL+RET+TEST+Jcc sequence in return, which is
absolutely idiotic.

Add to that a dynamic test of hyperv_paravisor_present, something
which is set once and never changed.

Replace all this idiocy with a single direct function call to the
right hypercall variant.

6204aea36b KVM: x86: Introduce EM_ASM_1
Replace fastops with C based stubs. There are a bunch of problems with
the current fastop infrastructure, most all related to their special
calling convention, which bypasses the normal C-ABI.

There are two immediate problems with this at present:

 - it relies on RET preserving EFLAGS; whereas C-ABI does not.

 - it circumvents compiler based control-flow-integrity checking
   because its all asm magic.

The first is a problem for some mitigations where the
x86_indirect_return_thunk needs to include non-trivial work that
clobbers EFLAGS (eg. the Skylake call depth tracking thing).

The second is a problem because it presents a 'naked' indirect call on
kCFI builds, making it a prime target for control flow hijacking.

Additionally, given that a large chunk of virtual machine performance
relies on absolutely avoiding vmexit these days, this emulation stuff
just isn't that critical for performance anymore.

As such, replace the fastop calls with normal C functions using the
'execute' member.

As noted by Paolo: this code was performance critical for pre-Westmere
(2010) and only when running big real mode code.

e8bd877fb7 ovl: fix possible double unlink
commit 9d23967b18 ("ovl: simplify an error path in
ovl_copy_up_workdir()") introduced the helper ovl_cleanup_unlocked(),
which is later used in several following patches to re-acquire the parent
inode lock and unlink a dentry that was earlier found using lookup.
This helper was eventually renamed to ovl_cleanup().

The helper ovl_parent_lock() is used to re-acquire the parent inode lock.
After acquiring the parent inode lock, the helper verifies that the
dentry has not since been moved to another parent, but it failed to
verify that the dentry wasn't unlinked from the parent.

This means that now every call to ovl_cleanup() could potentially
race with another thread, unlinking the dentry to be cleaned up
underneath overlayfs and trigger a vfs assertion.

ovl_create_temp() treats "workdir" as a parent in which it creates an

Prior to the commit identified below the lock was taken by the caller
which sometimes used I_MUTEX_PARENT and sometimes used I_MUTEX_NORMAL.
The use of I_MUTEX_NORMAL was incorrect but unfortunately copied into
ovl_create_temp().

Note to backporters: This patch only applies after the last Fixes given
below (post v6.16).  To fix the bug in v6.7 and later the
inode_lock() call in ovl_copy_up_workdir() needs to nest using
I_MUTEX_PARENT.

d8df126349 x86/cpu/hygon: Add missing resctrl_cpu_detect() in bsp_init helper
Since

  923f3a2b48 ("x86/resctrl: Query LLC monitoring properties once during boot")

resctrl_cpu_detect() has been moved from common CPU initialization code to
the vendor-specific BSP init helper, while Hygon didn't put that call in their
code.

This triggers a division by zero fault during early booting stage on our
machines with X86_FEATURE_CQM* supported, where get_rdt_mon_resources() tries
to calculate mon_l3_config with uninitialized boot_cpu_data.x86_cache_occ_scale.

Add the missing resctrl_cpu_detect() in the Hygon BSP init helper.

99d7ab8db9 memstick: Fix deadlock by moving removing flag earlier
The existing memstick core patch: commit 62c59a8786 ("memstick: Skip
allocating card when removing host") sets host->removing in
memstick_remove_host(),but still exists a critical time window where
memstick_check can run after host->eject is set but before removing is set.

In the rtsx_usb_ms driver, the problematic sequence is:

rtsx_usb_ms_drv_remove:          memstick_check:
  host->eject = true
  cancel_work_sync(handle_req)     if(!host->removing)
  ...                              memstick_alloc_card()
                                     memstick_set_rw_addr()
                                       memstick_new_req()
                                         rtsx_usb_ms_request()
                                           if(!host->eject)
                                           skip schedule_work
                                       wait_for_completion()
  memstick_remove_host:                [blocks indefinitely]
    host->removing = true
    flush_workqueue()
    [block]

1. rtsx_usb_ms_drv_remove sets host->eject = true
2. cancel_work_sync(&host->handle_req) runs
3. memstick_check work may be executed here <-- danger window
4. memstick_remove_host sets removing = 1

During this window (step 3), memstick_check calls memstick_alloc_card,
which may indefinitely waiting for mrq_complete completion that will
never occur because rtsx_usb_ms_request sees eject=true and skips
scheduling work, memstick_set_rw_addr waits forever for completion.

This causes a deadlock when memstick_remove_host tries to flush_workqueue,
waiting for memstick_check to complete, while memstick_check is blocked
waiting for mrq_complete completion.

Fix this by setting removing=true at the start of rtsx_usb_ms_drv_remove,
before any work cancellation. This ensures memstick_check will see the
removing flag immediately and exit early, avoiding the deadlock.

e251709aad mmc: sdhci-of-arasan: Ensure CD logic stabilization before power-up
During SD suspend/resume without a full card rescan (when using
non-removable SD cards for rootfs), the SD card initialization may fail
after resume. This occurs because, after a host controller reset, the
card detect logic may take time to stabilize due to debounce logic.
Without waiting for stabilization, the host may attempt powering up the
card prematurely, leading to command timeouts during resume flow.
Add sdhci_arasan_set_power_and_bus_voltage() to wait for the card detect
stable bit before power up the card. Since the stabilization time
is not fixed, a maximum timeout of one second is used to ensure
sufficient wait time for the card detect signal to stabilize.
