Thanks for your comments!
Lenovo SWRAID driver is a closed source driver at this time, I am afraid
it's not possible to submit it to kernel.
This patch is very important and critical for Lenovo next generation
Servers. I have tried to make sure this patch only impacts Lenovo

The information in /sys/kernel/debug/page_owner includes the migratetype of
the pageblock the page belongs to. This is also checked against the page's
migratetype (as declared by gfp_flags during its allocation), and the page is
reported as Fallback if its migratetype differs from the pageblock's o
The page_owner mechanism stores gfp_flags of an allocation and stack trace
that lead to it. During page migration, the original information is
practically replaced by the allocation of free page as the migration target.
Arguably this is less useful and might lead to all the page_owner info for
migr
CONFIG_PAGE_OWNER attempts to impose negligible runtime overhead when enabled
during compilation, but not actually enabled during runtime by boot param
page_owner=on. This overhead can be further reduced using the static key
mechanism, which this patch does.

During migration, page_owner info is now copied with the rest of the page, so
the stacktrace leading to free page allocation during migration is overwritten.
For debugging purposes, it might be however useful to know that the page has
been migrated since its initial allocation. This might happen ma
Changes since v3:
- Rebased on next-20160125
- Changed the %pg format string for flags to %pG due to clash with another
patch already merged merged
- Update GFP flags (patches 2, 3) for new changes and stuff I overlooked
the last time
- __GFP_X flags are now printed as __GFP_X instead of GFP_X
With the new printk format strings for flags, we can get rid of dump_flags()
in mm/debug.c.
This also fixes dump_vma() which used dump_flags() for printing vma flags.
However dump_flags() did a page-flags specific filtering of bits higher than
NR_PAGEFLAGS in order to remove the zone id part. For
The following patch will need to declare array of struct trace_print_flags
in a header. To prevent this header from pulling in all of RCU through
trace_events.h, move the struct trace_print_flags{_64} definitions to the new
lightweight tracepoint-defs.h header.

When updating tracing's show_gfp_flags() I have noticed that perf's
gfp_compact_table is also outdated. Fill in the missing flags and place a
note in gfp.h to increase chance that future updates are synced. Convert the
__GFP_X flags from "GFP_X" to "__GFP_X" strings in line with the previous
patch.

Add support for early printk by writing debug messages to the USB3
debug port. Users can use this type of early printk by specifying
kernel parameter of "earlyprintk=xdbc". This gives users a chance
of providing debug output.

In case of endpoint stall, software is able to detect the situation
by reading DCCTRL.HIT or DCCTRL.HOT bits. DbC follows the normal USB
framework to handle endpoint stall. When software detects endpoint
stall situation, it should wait until endpoint is recovered before
read or write oprations.

DbC might exit configured state in some cases (refer to 7.6.4.4 in
xHCI spec 1.1). Software needs detect and clear this situation by
clearing DCCTRL.DCR and wait until the DbC configured before read
or write oprations.
