The P2020 has a non-standard implementation of the SDHCI_HOST_CONTROL
register. This patch adds a QUIRK in the SDHCI header to signal that
a host controller has a non-standard SDHCI_HOST_CONTROL register. The

Nothing about the sched_clock implementation in the ARM port is

Use the generic sched_clock infrastructure instead of rolling our
own. This has the added benefit of fixing suspend/resume as
outlined in 6a4dae5 (ARM: 7565/1: sched: stop sched_clock()
during suspend, 2012-10-23) and correcting the timestamps when
the hardware returns a value instead of 0 upon the
The ARM architected system counter has at least 56 useable bits.
Add support for counters with more than 32 bits to the generic

dealing with wrap-around on these devices while benefiting from
the irqtime accounting and suspend/resume hand
Register with the ARM sched_clock framework now that it supports

This is mostly a resend of a patch series I sent a little over a month

The needs_suspend member is unused now that we always do the

non-initialised declarations on one l

No, I'm not going to apply this. Allowing users to randomly write to
devices could potentially lead to physical damage to the system and so
isn't somet

fetch_bp_busy_slots() and toggle_bp_slot() use for_each_online_cpu(),
this is obviously wrong wrt cpu_up() or cpu_down(), we can over/under
account the per-cpu numbers.
For example:

# perf record -e mem:0x10 -p 1 &
# echo 1 >

this doesn't account the "all cpus" events with iter->cpu < 0.
This means that, say, registe

This patch makes use of the new format specifier %pa that was introduced
by the following commit.

("lib/vsprintf.c: add %pa format specifier for phys_addr_t types")
The addition of urb->transfer_dma and urb->actual_length is also done a

Hello,
Thank's for your pointers.
I will send a patch that applies on top of Felipe's patch.
