[PATCH V1 Resend 00/10] trivial: Drop unlikely before IS_ERR(_OR_NULL)

by Viresh Kumar

Hi Jiri, Andrew Morton suggested to take these patches through your tree and so another resend. This cleans up the usage of IS_ERR(_OR_NULL)(), where the callers have added additional unlikely compiler flag to them. It also fixes the definition of IS_ERR_OR_NULL(), to use unlikely for all checks it does.

[PATCH V5 1/2] ACPI / EC: Fix broken 64bit big-endian users of 'global_lock'

by Viresh Kumar

global_lock is defined as an unsigned long and accessing only its lower 32 bits from sysfs is incorrect, as we need to consider other 32 bits for big endian 64-bit systems. There are no such platforms yet, but the code needs to be robust for such a case. Fix that by changing type of 'global_lock' to u32. Signed-off-by: Viresh Kumar <viresh.kumar(a)linaro.org> --- BCC'd a lot of people (rather than cc'ing them) to make sure - the series reaches them - mailing lists do not block the patchset due to long cc list - and we don't spam the BCC'd people for every reply V4->V5: - Switch back to the original solution of making global_lock u32. --- drivers/acpi/ec_sys.c | 2 +- drivers/acpi/internal.h | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/acpi/ec_sys.c b/drivers/acpi/ec_sys.c index b4c216bab22b..bea8e425a8de 100644 --- a/drivers/acpi/ec_sys.c +++ b/drivers/acpi/ec_sys.c @@ -128,7 +128,7 @@ static int acpi_ec_add_debugfs(struct acpi_ec *ec, unsigned int ec_device_count) if (!debugfs_create_x32("gpe", 0444, dev_dir, (u32 *)&first_ec->gpe)) goto error; if (!debugfs_create_bool("use_global_lock", 0444, dev_dir, - (u32 *)&first_ec->global_lock)) + &first_ec->global_lock)) goto error; if (write_support) diff --git a/drivers/acpi/internal.h b/drivers/acpi/internal.h index 9e426210c2a8..9db196de003c 100644 --- a/drivers/acpi/internal.h +++ b/drivers/acpi/internal.h @@ -138,7 +138,7 @@ struct acpi_ec { unsigned long gpe; unsigned long command_addr; unsigned long data_addr; - unsigned long global_lock; + u32 global_lock; unsigned long flags; unsigned long reference_count; struct mutex mutex; -- 2.4.0

[PATCH] arm: Fix backtrace generation when IPI is masked

by Daniel Thompson

Currently on ARM when <SysRq-L> is triggered from an interrupt handler (e.g. a SysRq issued using UART or kbd) the main CPU will wedge for ten seconds with interrupts masked before issuing a backtrace for every CPU except itself. The new backtrace code introduced by commit 96f0e00378d4 ("ARM: add basic support for on-demand backtrace of other CPUs") does not work correctly when run from an interrupt handler because IPI_CPU_BACKTRACE is used to generate the backtrace on all CPUs but cannot preempt the current calling context. This can be fixed by detecting that the calling context cannot be preempted and issuing the backtrace directly in this case. Some small changes to the generic code are required to support this.
