Commit 36d4b36b6959 ("lib/nodemask: inline next_node_in() and
node_random()") refactored some code by moving node_random() from
lib/nodemask.c to include/linux/nodemask.h, thus requiring nodemask.h to
include random.h, which conditionally defines add_latent_entropy()
depending on whether the macro
Based on the original work from Sam Bobroff.
Currently, EEH recovery is entirely serialized and takes place within
a single kernel thread. This can cause recovery to take a long time
when there are many devices.
To shorten recovery time, this change allows recovery to proceed in
parallel in two
Based on the original work from Sam Bobroff.
There is currently little synchronization between EEH error detection
(eeh_dev_check_failure()), EEH error recovery
(eeh_handle_{normal,special}_event()) and the PCI subsystem (device
addition and removal), and so there are race conditions that lead to
Hi,
EEH reocvery is currently serialized and these patches shorten
the time taken for EEH recovery by making the recovery to run
in parallel. The original author of these patches is Sam Bobroff,
I have rebased and tested these patches.
On powervm with 64 VFs and I see approximately 48% reduction
Based on the original work from Sam Bobroff.
Give a unique ID to each recovery event, to ease log parsing
and prepare for parallel recovery.
Also add some new messages with a very simple format that may
be useful to log-parsers.

This converts from seq_buf to printbuf. We're using printbuf in external
buffer mode, so it's a direct conversion, aside from some trivial
refactoring in cpu_show_meltdown() to make the code more consistent.

It is better to use "unsigned int" instead of "unsigned", line 24.

Since commit 591b4b268435 ("powerpc/code-patching: Pre-map patch area")
the patch area is premapped so intermediate page tables are already
allocated.
Use __set_pte_at() directly instead of the heavy map_kernel_page(),
at for unmapping just do a pte_clear() followed by a
