Stopped the periodic update of blocked load when all idle CPUs have fully
decayed. We introduce a new nohz.has_blocked that reflect if some idle
CPUs has blocked load that have to be periodiccally updated. nohz.has_blocked
is set everytime that a Idle CPU can have blocked load and it is then clear
Instead of using the cfs_rq_is_decayed() which monitors all *_avg
and *_sum, we create a cfs_rq_has_blocked() which only takes care of
util_avg and load_avg. We are only interested by these 2 values which are
decaying faster than the *_sum so we can stop the periodic update earlier.
Signed-off-by:
When NEWLY_IDLE load balance is not triggered, we might need to update the
blocked load anyway. We can kick an ilb so an idle CPU will take care of
updating blocked load or we can try to update them locally before entering
idle. In the latter case, we reuse part of the nohz_idle_balance.

VirtualBox hosts can share folders with guests, this commit adds a
VFS driver implementing the Linux-guest side of this, allowing folders
exported by the host to be mounted under Linux.
This driver depends on the guest <-> host IPC functions exported by

The new hashing feature of unadorned printk("%p") makes it hard to spot if
the pointer actually carries an error value. Make %p print any pointer
that matches IS_ERR() as a negative integer.

Kees suggested that, 'offset' is unsigned long, not a pointer,
thus %lx should be used to print it, not the %px. Also, I don't

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another

In most cases this other symbol is an architecture or platform specific

Hi all,
If NO_DMA=y, get_dma_ops() returns a reference to the non-existing
symbol bad_dma_ops, thus causing a link failure if it is ever used.
The intention of this is twofold:
1. To catch users of the DMA API on systems that do no support the DMA
mapping API,
2. To avoid buildin
SMMU_CBn_FSYNR0 definition from SMMU v2 architecture document
says that, the S1CBNDX[23:16] field is only valid if SMMU_IDR0.NTS==1.
So, update the fsynr in context bank fault handler, so that the
fault message displays cbndx only when we have nested translations
enabled.
Otherwise, it is confusing
