armadillo800eva default boot loader is "hermit", and it's tag->u.core.flags has flag when kernel boots. Because of this, ${LINUX}/arch/arm/kernel/setup.c :: parse_tag_core() didn't remove MS_RDONLY flag from root_mountflags. Thus, the rootfs is mounted as "readonly". This patch adds "rw" kernel parameter, and enable read/write mounts for rootfs Cc: Masahiro Nakai <nakai@atmark-techno.com> Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms@verge.net.au>

2012-08-31ARM: shmobile: mackerel: fixup usb module orderKuninori Morimoto1-1/+2
renesas_usbhs driver can play role as both Host and Gadget. In case of Gadget, it requires not only renesas_usbhs but also usb gadget module (like g_ether). So, renesas_usbhs driver calls usb_add_gadget_udc() on probe time. Because of this behavior, Host port plays also Gadget role if kernel has both Host/Gadget support. In mackerel case, from 0ada2da51800a4914887a9bcf22d563be80e50be (ARM: mach-shmobile: mackerel: use renesas_usbhs instead of r8a66597_hcd) usb0 plays Gadget role, and usb1 plays Host role, and current mackerel board probes as usb1 -> usb0. Thus, 1st installed usb gadget module (like g_ether) will be assigned to usb1 (= usb Host port), and 2nd module to usb0 (= usb Gadget port). It is very confusable for user.

2012-08-24powerpc/perf: Use pmc_overflow() to detect rolled back eventsSukadev Bhattiprolu1-1/+1
For certain speculative events on Power7, 'perf stat' reports far higher event count than 'perf record' for the same event. As described in following commit, a performance monitor exception is raised even when the the performance events are rolled back. commit 0837e3242c73566fc1c0196b4ec61779c25ffc93 Author: Anton Blanchard <anton@samba.org> Date: Wed Mar 9 14:38:42 2011 +1100 perf_event_interrupt() records an event only when an overflow occurs. But this check for overflow is a simple 'if (val < 0)'. Because the events are rolled back, this check for overflow fails and the event is not recorded. perf_event_interrupt() later uses pmc_overflow() to detect the overflow and resets the counters and the events are lost completely. To properly detect the overflow of rolled back events, use pmc_overflow() even when recording events. To reproduce: $ cat strcpy.c #include <stdio.h> #include <string.h> main() { char buf[256]; alarm(5); while(1) strcpy(buf, "string1"); } $ perf record -e r20014 ./strcpy $ perf report -n > report.1 $ perf stat -e r20014 > report.2 # Compare report.1 and report.2 Reported-by: Maynard Johnson <mpjohn@us.ibm.com> Signed-off-by: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
