If a protocol doesn't support zerocopy it will silently fall back to

so it's better to fail such requests instead.

The KVM_X86_SET_MSR_FILTER ioctls contains a pointer in the passed in
struct which means it has a different struct size depending on whether
it gets called from 32bit or 64bit code.
This patch introduces compat code that converts from the 32bit struct to
its 64bit counterpart which then gets used going forward internally.
With this applied, 32bit QEMU can successfully set MSR bitmaps when
running on 64bit kernels.

the passive cable check above the active checks, so as not to be
improperly identified as an active cable. This will fix the issue for

PLL control setting(RRC) is needed only in fixed PHY configuration to
fix the peer-peer issues. Without the PLL control setting, the link up
takes longer time in a fixed phy configuration.
Driver implements SW RRC for Autoneg On configuration, hence PLL control
setting (RRC) is not needed for AN On configuration, and can be skipped.
Also, PLL re-initialization is not needed for PHY Power Off and RRC
commands. Otherwise, they lead to mailbox errors. Added the changes
accordingly.

Hi,
The patchset aims to fix one problem of bpf memory allocator destruction
when there is PREEMPT_RT kernel or kernel with arch_irq_work_has_interrupt()
being false (e.g. 1-cpu arm32 host or mips). The root cause is that
there may be busy refill_work when the allocator is destroying and it
may incur oops or other problems as shown in patch #1. Patch #1 fixes
the problem by waiting for the completion of irq work during destroying
and patch #2 is just a clean-up patch based on patch #1. Please see
individual patches for more details.
Comments are always welcome.
Change Log:

* patch 1: fix typos and add notes about the overhead of irq_work_sync()
* patch 1 & 2: add Acked-by tags from sdf@google.com

Except for waiting_for_gp list, there are no concurrent operations on
free_by_rcu, free_llist and free_llist_extra lists, so use
__llist_del_all() instead of llist_del_all(). waiting_for_gp list can be
deleted by RCU callback concurrently, so still use llist_del_all().

A busy irq work is an unfinished irq work and it can be either in the
pending state or in the running state. When destroying bpf memory
allocator, refill_work may be busy for PREEMPT_RT kernel in which irq
work is invoked in a per-CPU RT-kthread. It is also possible for kernel
with arch_irq_work_has_interrupt() being false (e.g. 1-cpu arm32 host or
mips) and irq work is inovked in timer interrupt.
The busy refill_work leads to various issues. The obvious one is that
there will be concurrent operations on free_by_rcu and free_list between
irq work and memory draining. Another one is call_rcu_in_progress will
not be reliable for the checking of pending RCU callback because
do_call_rcu() may have not been invoked by irq work yet. The other is
there will be use-after-free if irq work is freed before the callback
of irq work is invoked as shown below:

When an extended state component is not present in fpstate, but in init
state, the function copies from init_fpstate via copy_feature().
But, dynamic states are not present in init_fpstate because of all-zeros
init states. Then retrieving them from init_fpstate will explode like this:

Adjust the 'mask' to zero out the userspace buffer for the features that
are not available both from fpstate and from init_fpstate.
The dynamic features depend on the compacted XSAVE format. Ensure it is
enabled before reading XCOMP_BV in init_fpstate.

Pull selinux fix from Paul Moore:
"A small SELinux fix for a GFP_KERNEL allocation while a spinlock is
held.
The patch, while still fairly small, is a bit larger than one might
expect from a simple s/GFP_KERNEL/GFP_ATOMIC/ conversion because we
added support for the function to be called with different gfp flags
depending on the context, preserving GFP_KERNEL for those cases that
can safely sleep"

When a console stack dump is initiated with CONFIG_GCOV_PROFILE_ALL
enabled, show_trace_log_lvl() gets out of sync with the ORC unwinder,
causing the stack trace to show all text addresses as unreliable:

This happens when the compiled code for show_stack() has a single word
on the stack, and doesn't use a tail call to show_stack_log_lvl().
(CONFIG_GCOV_PROFILE_ALL=y is the only known case of this.) Then the
__unwind_start() skip logic hits an off-by-one bug and fails to unwind
all the way to the intended starting frame.
Fix it by reverting the following commit:
f1d9a2abff ("x86/unwind/orc: Don't skip the first frame for inactive tasks")
The original justification for that commit no longer exists. That
original issue was later fixed in a different way, with the following
commit:
f2ac57a4c4 ("x86/unwind/orc: Fix inactive tasks with stack pointer in %sp on GCC 10 compiled kernels")

ethnl_default_dump_one() passes NULL as info.
It's correct not to set extack during dump, as we should just
silently skip interfaces which can't provide the information.

The generic EFI stub can be instructed to avoid SetVirtualAddressMap(),
and simply run with the firmware's 1:1 mapping. In this case, it
populates the virtual address fields of the runtime regions in the
memory map with the physical address of each region, so that the mapping
code has to be none the wiser. Only if SetVirtualAddressMap() fails, the
virtual addresses are wiped and the kernel code knows that the regions
cannot be mapped.
However, wiping amounts to setting it to zero, and if a runtime region
happens to live at physical address 0, its valid 1:1 mapped virtual
address could be mistaken for a wiped field, resulting on loss of access
to the EFI services at runtime.
So let's only assume that VA == 0 means 'no runtime services' if the
region in question does not live at PA 0x0.

The linker script symbol definition that captures the size of the
compressed payload inside the zboot decompressor (which is exposed via
the image header) refers to '.' for the end of the region, which does
not give the correct result as the expression is not placed at the end
of the payload. So use the symbol name explicitly.

To stop the bots from sending sparse warnings to me and the list about
efi_main() not having a prototype, decorate it with asmlinkage so that
it is clear that it is called from assembly, and therefore needs to
remain external, even if it is never declared in a header file.
