There are several factors which contribute to your perception of

1. I try to extract from every feedback the information about the amount

Add the kernel command line tracepoint_printk option that will

Linus,
This code is a fork from the trace-3.19 pull as it needed the trace_seq
clean ups from that branch.
This code solves the issue of performing stack dumps from NMI context.
The issue is that printk() is not safe from NMI context as if the NMI
were to trigger when a printk() was being perfor

A full task stack dump of all tasks on a machine can generate more than

While trying to deal with errata i856 on the dra7xx I encountered some

11 platforms require at least one of these workarounds to be enabled; 22
platforms do not. In the latter case we can fall back to a generic version.
Note that this also deletes an orphaned reference to RM9000_CDEX_SMP_WAR.

From: Brian Norris
Wakeable interrupts might be pending at boot/init time, because wakeup
interrupts might have triggered a resume from S5. So don't clear such
wakeups.
This means that any driver which requests a wakeable interrupt bit
should be prepared to handle an interrupt as soon as they ca
Currently the driver assumes that REG_BASE+0x00 is the IRQ enable mask,
and REG_BASE+0x04 is the IRQ status mask. This is true on BCM3384 and
BCM7xxx, but it is not true for some of the controllers found on BCM63xx
chips. So we will change a couple of key assumptions:
- Don't assume that both t
BMIPS 3300/435x/438x CPUs have a readahead cache that is separate from
the L1/L2. During a DMA operation, accesses adjacent to a DMA buffer
may cause parts of the DMA buffer to be prefetched into the RAC. To
avoid possible coherency problems, flush the RAC upon DMA completion.

This is the main peripheral IRQ controller on the BCM7xxx MIPS chips;
it has the following characteristics:
- 64 to 160+ level IRQs
- Atomic set/clear registers
- Reasonably predictable register layout (N status words, then N
mask status words, then N mask set words, then N mask clear words)
Enabling support for more than one BMIPS CPU in the same build may
result in different L1_CACHE_SHIFT values, e.g.
CPU_BMIPS5000 selects MIPS_L1_CACHE_SHIFT_7
CPU_BMIPS4380 selects MIPS_L1_CACHE_SHIFT_6
anything else defaults to MIPS_L1_CACHE_SHIFT_5
