Using pci_alloc_irq_vectors() instead of the deprecated
pci_enable_msix() allows to remove the msix_entry from
struct octeon_i2c and thus to get rid of the config symbol check.

In case of arbitration lost adequate interrupt sometimes is not signaled.
As a result transfer timeouts and is not retried, as it should. To avoid
such cases code is added to check transaction status in case of every

Previous vGPU type create tried to determine vGPU type name e.g _1, _2
based on the number of mdev devices can be created, but different type
might have very different resource size depending on physical device.
We need to split type name vs. actual mdev resource and create fixed
vGPU type with determined size for consistence.
With this we'd like to fix vGPU types for _1, _2, _4 and _8 now, each
type has fixed defined resource size. Available mdev instances that could
be created is determined by physical resource, and user should query
for that before creating.

Releasing shadow PPGTT pages is not enough when vGPU reset, the
guest page table tracking data should has same life-cycle with
all the shadow PPGTT pages; Otherwise there is no chance to
re-shadow the PPGTT pages without free the guest page table
tracking data.
This patch clear the PPGTT reset logic and make the vGPU reset in

send_display_send_uevent() sends two environment variable, and the
first one GVT_DISPLAY_READY is set including a new line at the end of
the string; that is obviously superfluous and wrong -- at least, it
*looks* so when you only read the code.
However, it doesn't appear in the actual output by a (supposedly
unexpected) trick. The code uses snprintf() and truncates the string
in size 20 bytes. This makes the string as GVT_DISPLAY_READY=0 or
...=1 including the trailing NUL-letter. That is, the '\n' found in
the format string is always cut off as a result.
Although the code gives the correct result, it is confusing. This
patch addresses it, just removing the superfluous '\n' from the format
string for avoiding further confusion. If the argument "ready" were
not a bool, the size 20 should be corrected as well. But it's a
bool, so we can leave the magic number 20 as is for now.
FWIW, the bug was spotted by a new GCC7 warning:
drivers/gpu/drm/i915/gvt/handlers.c: In function 'pvinfo_mmio_write':
drivers/gpu/drm/i915/gvt/handlers.c:1042:34: error: 'snprintf' output truncated before the last format character [-Werror=format-truncation=]

This patch introcudes a new kernel module pkey which is providing
protected key handling and management functions. The pkey API is
available within the kernel for other s390 specific code to create
and manage protected keys. Additionally the functions are exported
to user space via IOCTL calls. The implementation makes extensive
use of functions provided by the zcrypt device driver. For
generating protected keys from secure keys there is also a CEX
coprocessor card needed.

This patch introduces the possibility to reset the

This can be used to set a clear state on the counters before
running an application and try out if and which hardware is
actually used. If the request_count counter of a card is
reset, for all associated queues the request_count is also
zeroed. If just a queue request_count is reset the card
counter is not updated however.

Unbalanced set_fs usages (e.g. early exit from a function and a
forgotten set_fs(USER_DS) call) may lead to a situation where the
secondary asce is the kernel space asce when returning to user
space. This would allow user space to modify kernel space at will.
This would only be possible with the above mentioned kernel bug,
however we can detect this and fix the secondary asce before returning
to user space.
Therefore a new TIF_ASCE_SECONDARY which is used within set_fs. When
returning to user space check if TIF_ASCE_SECONDARY is set, which
would indicate a bug. If it is set print a message to the console,
fixup the secondary asce, and then return to user space.
This is similar to what is being discussed for x86 and arm:

Previously, in getxattr we will load all entries both in inline xattr and

flow shows low efficiency, since if we can lookup and hit in inline xattr

block, which can obviously save cpu time and IO latency.

A dead loop can be triggered in f2fs_fiemap() using the test case
as below:
...
fd = open();
fallocate(fd, 0, 0, 4294967296);
ioctl(fd, FS_IOC_FIEMAP, fiemap_buf);
...
It's caused by an overflow in __get_data_block():
...
bh->b_size = map.m_len << inode->i_blkbits;
...
map.m_len is an unsigned int, and bh->b_size is a size_t which is 64 bits
on 64 bits archtecture, type conversion from an unsigned int to a size_t
will result in an overflow.
In the above-mentioned case, bh->b_size will be zero, and f2fs_fiemap()
will call get_data_block() at block 0 again an again.
Fix this by adding a force conversion before left shift.
