This is against 4.19 so you may have to tweak them a bit.
Feel free to upstream them.

Still taking patches for fsl_udc_core.c ?
I figured this driver was obsolete and should be moved
I cannot figure out how the xxxK reserved item works in:
Memory: 880608K/983040K available (9532K kernel code, 1104K rwdata, 3348K
rodata, 1088K init, 1201K bss, 36896K reserved ...
Is there a way to tune(lower it) this memory?

In __die(), see below, there is this call to notify_send() with SIGSEGV
hardcoded, this seems odd
to me as the variable "err" holds the true signal(in my case SIGBUS)
Should not SIGSEGV be replaced with the true signal no.?

But recently rtc driver ds1307 does care and tries to correct wday.
Add wday calculation(stolen from rtc_time64_to_tm) to to_tm() to please ds1307.

espi does not look for a OF cell-index property which
makes the bus numbering dynamic only. This add an

Hi, just saw this and thought of a small patch I just wrote for mdio bus, o idea
if it is relevant but here goes:

This test, taken from perl Configure, fails on my ppc32, should it?
semctl IPC_STAT failed: errno = Bad Address
is what I get, kernel is 4.1.43

We got some "broken" boards(mpx8321) where UART RX is held low(BREAK)
There we get a few:
serial8250: too much work for irq18
and the board freezes.
Looking inte to driver/CPU there is an errtum(A-004737) w.r.t BREAK handling
and I can see we are hitting the irq function fsl8250_handle_irq()
Some PCIe errors, don't know which(possibly by PCIe 4 in

Having problems to mmap PCI UIO devices and stumbeled over this page:
http://billfarrow.blogspot.se/2010/09/userspace-access-to-pci-memory.html
it claims some adjustments are needed for UIO mmap over PCI to work.
These are #if 0 ATM and trying to enable them fails build.
Can this be fixed to at

get_user() had it args reversed causing NIP to be NULL:ed instead
of fixing up the PCI access.
Note: This still hangs my P1020 Freescale CPU hard, but at least
I get a NIP now.
