That's how kernel development is done in the end...:)
I'd be curious to know how you got the git3.lwn.net name in your remote,
though, if by any chance you can remember. That shouldn't
It has been supported as a generic lm85 for quite some time.

Add an option so the module section is just after the mapped kernel. It
will ensure position independent modules are always at the right
distance from the kernel and do not require mcmodule=large. It also
optimize the available size for modules by getting rid of the empty
space on kernel randomizat

Since there are a few archs out there that call preempt_schedule_irq()
within a need_resched() loop, point out that it's not needed.

A while back (before [1]), i386 had this in the tail of its irq
handling code:
need_resched:
movl TI_flags(%ebp), %ecx # need_resched set ?
testb $_TIF_NEED_RESCHED, %cl
jz restore_all
testl $IF_MASK,EFLAGS(%esp) # interrupts off (exception path)

Repurpose the existing EFI earlyprintk code to implement support for
'earlycon=efi' for arm64 systems, allowing the graphical console
to be used instead of the serial port for early debug output.
Changes since v2:
- update patch #1 so that no attempts are made to build the memencrypt related
ear
Turn ARCH_USE_MEMREMAP_PROT into a generic Kconfig symbol, and fix the
dependency expression to reflect that AMD_MEM_ENCRYPT depends on it,
instead of the other way around. This will permit ARCH_USE_MEMREMAP_PROT
to be selected by other architectures and other subsystems, such as
earlycon for efifb
Move the x86 EFI earlyprintk implementation to a shared location under
drivers/firmware and tweak it slightly so we can expose it as an earlycon
implementation (which is generic) rather than earlyprintk (which is only
implemented for a few architectures)
This also involves switching to write-combi

commit 3fb72f1e6e61 ("ipconfig wait for carrier") added a
"wait for carrier" policy, with a fixed worst case maximum wait
of two minutes.
Now make the wait for carrier timeout configurable on the kernel
commandline and use the 120s as the default.
The timeout messages introduced with

Weird, for me it works fine. The generated html at kernel.org [1] also
