This patchset contains various fixes for KASAN. That includes:
1. Improving reported bug types.
Making KASAN distinguish and report the following types of bugs:
slab-out-of-bounds, stack-out-of-bounds, global-out-of-bounds
use-after-free, null-ptr-deref, user-memory-access, wild-memory-access.
2
Each access with address lower than kasan_shadow_to_mem(KASAN_SHADOW_START)
is reported as user-memory-access. This is not always true, the accessed
address might not be in user space. Fix this by reporting such accesses as
null-ptr-derefs or wild-memory-accesses.
There's another reason for this c
Update the names of the bad access types to better reflect the type of
the access that happended and make these error types "literals" that can
be used for classification and deduplication in scripts.

Per-pkg events need to be captured once per processor
socket. The code in check_per_pkg() ensures only one
value per processor package is used. However there is
a problem with this function in case the first CPU of
the package does not measure anything for the per-pkg event,
but other CPUs do.

We are going to rework how compound_head() work. It will not use
page->first_page as we have it now.
The only other user of page->first_page beyond compound pages is
zsmalloc.
Let's use page->private instead of page->first_page here. It occupies
the same storage space.

Hugh has pointed that compound_head() call can be unsafe in some
context. There's one example:
CPU0CPU1
isolate_migratepages_block()
page_count()
compound_head()
!!PageTail() == true
put_page()
On 64 bit system we have enough space in struct page to encode
compound_dtor and compound_order with unsigned int.
On x86-64 it leads to slightly smaller code size due usesage of plain
MOV instead of MOVZX (zero-extended move) or similar effect.

textdata bss dec
Let's try to be consistent about data type of page order.

The patch halves space occupied by compound_dtor and compound_order in
struct page.
For compound_order, it's trivial long -> short conversion.
For get_compound_page_dtor(), we now use hardcoded table for destructor
lookup and store its index in the struct page instead of direct pointer
to destruc
Here's my attempt on fixing race in compound_head(). It should make
compound_head() reliable in all contexts.
The last patch is optional.
It applies cleanly into mmotm patchstack just before my page-flags
patchset.
As expected, it causes few conflicts with patches:

Hi Namhyung,

The pci-host-generic driver parses the linux,pci-probe-only property,
and assumes that it will have a boolean parameter.
Turns out that the Seattle DTS file has a naked "linux,pci-probe-only"
property, which leads to the driver dereferencing some unsuspecting
memory location. Nothing really bad ha
The linux,pci-probe-only property mandates an argument to indicate
whether or not to engage the "probe-only" mode, but the Seattle
DTS just provides a naked property, which is illegal.
Also, it turns out that the board is perfectly happy without
probe-only, so let's drop this altogether.

When pci-host-generic looks for the probe-only property, it seems
to trust the DT to be correctly written, and assumes that there
is a parameter to the property.
Unfortunately, this is not always the case, and some firmware expose
this property naked. The driver ends up making a decision based on
Both pci-host-generic and Pseries parse the "linux,pci-probe-only"
property to engage the PCI_PROBE_ONLY mode, and both have a subtle
bug that can be triggered if the property has no parameter.
Provide a generic, safe implementation that can be used by both.
