Core-scheduling prevents hyperthreads in usermode from attacking each
other, but it does not do anything about one of the hyperthreads
entering the kernel for any reason. This leaves the door open for MDS
and L1TF attacks with concurrent execution sequences between
hyperthreads.

(Surprised what looked to me like a typo compiled). Would a
checkpatch warning be helpful, too?
Hello!
This series is continuation of main core-sched v6 series [1] and adds support
for syscall and IRQ isolation from usermode processes and guests. It is key to
safely entering kernel mode in an HT while the other HT is in use by a user or
guest. The series also fixes CPU hotplug issues
syzbot suspects this issue was fixed by commit:

start commit:
When an unsafe region is entered on an HT, an IPI needs to be sent to
siblings to ensure they enter the kernel.
Following are the reasons why we would like to use irq_work to implement
forcing of sibling into kernel mode:
1. Existing smp_call infrastructure cannot be used easily since we could
%u is used for unsigned so we need to cast the int variable to u32 to avoid
compiler warning.

Since l2cap_sock_teardown_cb doesn't acquire the channel lock before
setting the socket as zapped, it could potentially race with
l2cap_sock_release which frees the socket. Thus, wait until the cleanup
is complete before marking the socket as zapped.
This race was reproduced on a JBL GO speaker

The driver waits for the TPC vector pipe to be empty before checking if the
TPC kernel has finished executing, but the code doesn't validate that the
pipe was indeed empty, it just wait for it without checking the return

needed or not, during exit to user or guest mode.

Currently only RCU hooks for idle entry/exit are called. In later
patches, kernel-entry protection functionality will be added.

Hotplug fixes to core-scheduling require a new cpumask iterator which iterates
through all online cpus in both the given cpumasks. This patch introduces it.

In ftrace, add more fields to the cros_ec command event:
- Add size of commands to check if they are properly set.
- Add offset (in case an EC is cascaded being another EC),
to allow proper command output
With:

The debugobject core could be slightly harder to corrupt if we make the
debug_obj_descr a pointer to const memory. Depending on the
architecture, const datastructures are placed into read-only memory and
thus are harder to corrupt or hijack. This descriptor is used to fix up
stuff like timers and

There are multiple loops in pick_next_task that iterate over CPUs in
smt_mask. During a hotplug event, sibling could be removed from the
smt_mask while pick_next_task is running. So we cannot trust the mask
across the different loops. This can confuse the logic.
Add a retry
