A couple of urgent fixes for PTI:
- Fix a PTE mismatch between user and kernel visible mapping of the cpu
entry area (differs vs. the GLB bit) and
The 'if_nospec' primitive marks locations where the kernel is disabling
speculative execution that could potentially access privileged data. It
is expected to be paired with a 'nospec_{ptr,load}' where the user
controlled value is actually consumed. Architectures can optionally

That would definitely be the right approach.
However, that's also probably quite challenging for the gcc option.

It has to be done at compile time because it requires a compiler option.
Most of the indirect calls are in C code.
So it cannot just patched in, only partially out.

I guess half of the lkml people already know, but others may have

few days. And ... it is. Apparently you can read kernel memory from
userspace, abusing speculative execution on modern CPUs.

All right, here's the dmesg from the kernel compiled from drm-tip (in
sync with upstream at the time of the compilation earlier today), with
CONFIG_DRM_I915_DEBUG_GEM=y
I crashed it by opening 20+ xterm windows. Doesn't always do it though

this is no surprise. The problem shows up only if the AWAKE bit in UART
Status Register 1 is set before we go into suspend. My understanding is
that
Commit 2b83ff96f51d ("led: core: Fix brightness setting when setting
delay_off=0")
replaced del_timer_sync(&led_cdev->blink_timer) with led_stop_software_blink(),
which in addition to the former also clears LED_BLINK_SW flag.
The fact that the function clears also blink_delay_on and blink_delay_o
