| | * ARM: oprofile: Fix backtraces in timer modeAri Kauppi2011-01-261-10/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Always allow backtraces when using oprofile on ARM, even if a PMU isn't present. Restores functionality originally introduced in commit 1b7b56982fdcd9d85effd76f3928cf5d6eb26155 ("oprofile: Always allow backtraces on ARM") by Richard Purdie. It is not that obvious, but there is now only one oprofile_arch_init() function. So the .backtrace callback is available also in timer mode. Implemented by removing code and using stubs for oprofile_perf_{init, exit} provided by <linux/oprofile.h>. This allows cleaning of other architecture specific implementations too.

This meant that setting breakpoints on these architectures would appear to succeed, although they would never fire in reality.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP2 (armv6) and MX3 turn off support for the V6K instructions, which when they include support for SMP kernels means that the resulting kernel is unsafe on SMP and can result in corrupted filesystems as we end up using unsafe bitops. Re-enable the use of V6K instructions on such kernels, and let such kernels running on V6 CPUs eat undefined instruction faults which will be much safer than filesystem corruption. Next merge window we can fix this properly (as it requires a much bigger set of changes.) Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

The Devkit8000 uses twl4030_ledA configured as output gpio only for the lcd enable line. twl4030_gpio.1 is used through the generic gpio functions while ledA is used via low level twl4030 calls. This patch removes the low level calls and use the generic gpio functions for initialization and use of ledA. This patch also fixes a bug where the lcd would not power down when blanking. Further this patch fixes an indentation issue. The comment line uses eight whitespace and is replaced with a hard tab. gpio_request + gpio_direction_output are replaced with gpio_request_one. The return value of gpio_request_one is used to set the value of the gpio to -EINVAL when unsuccessful, so that gpio_is_valid can detect the unsuccessful request. But already successful requested gpios are not freed.

Rather than forcing the state of MPU powerdomain to on, simply read the current value and restore it after the ROM code has run. This only affects the !CPUidle case since when CPUidle is enabled, the MPU power state is dynamically changed by CPUidle. In the !CPUidle case, MPU power state is initialized once at init and never touched. Acked-by: Tero Kristo <tero.kristo@nokia.com> Signed-off-by: Kevin Hilman <khilman@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FREQ is a ridiculously short name for a platform-specific macro in a generic header, and it now conflicts with an enumeration in the gspca/ov519 driver. Also delete conditional reference to ixp4xx_get_board_tick_rate() which is not defined anywhere. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>
