To allow flexible configuration of IDE introduce HAVE_IDE.
All archs except arm, um and s390 unconditionally select it.
For arm the actual configuration determine if IDE is supported.This is a step towards introducing drivers/Kconfig for arm.

Convert special mapping install from nopage to fault.
Because the "vm_file" is NULL for the special mapping, the generic VM
code has messed up "vm_pgoff" thinking that it's an anonymous mapping
and the offset does't matter. For that reason, we need to undo the
vm_pgoff offset that got added into vmf->pgoff.[ We _really_ should clean that up - either by making this whole special
mapping code just use a real file entry rather than that ugly array of
"struct page" pointers, or by just making the VM code realize that
even if vm_file is NULL it may not be a regular anonymous mmap.

Fix the FRV cmpxchg_local by breaking the following header dependency loop :
linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h
-> asm-frv/system.h ->
asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.hand
linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h ->
asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.hIn order to fix this :
- Move the atomic_test_and_ *_mask inlines from asm-frv/atomic.h (why are they
there at all anyway ? They are not touching atomic_t variables!) to
asm-frv/bitops.h.Also fix a build issue with cmpxchg : it does not cast to (unsigned long *)
like other architectures, to deal with it in the cmpxchg_local macro.FRV builds fine with this patch.

Signed-off-by: Roland Dreier -
This patch acts as a preparation for using checksum offload for IB
devices capable of inserting/verifying checksum in IP packets. The
patch does not actaully turn on NETIF_F_SG - we defer that to the
patches adding checksum offload capabilities.We only add support for send gathers for datagram mode, since existing
HW does not support checksum offload on connected QPs.Signed-off-by: Michael S. Tsirkin

All current InfiniBand devices can handle all DMA addresses, and it's
hard to imagine anyone would be silly enough to build a new device
that couldn't. Therefore, enable the NETIF_F_HIGHDMA feature for IPoIB.This has no effect for no, but is needed when we enable gather/scatter
support and checksum stateless offloads.Signed-off-by: Eli Cohen

ConnectX HCA supports shrinking WQEs, so that a single work request
can be made of multiple units of wqe_shift. This way, WRs can differ
in size, and do not have to be a power of 2 in size, saving memory and
speeding up send WR posting. Unfortunately, if we do this then the
wqe_index field in CQEs can't be used to look up the WR ID anymore, so
our implementation does this only if selective signaling is off.Further, on 32-bit platforms, we can't use vmap() to make the QP
buffer virtually contigious. Thus we have to use constant-sized WRs to
make sure a WR is always fully within a single page-sized chunk.Finally, we use WRs with the NOP opcode to avoid wrapping around the
queue buffer in the middle of posting a WR, and we set the
NoErrorCompletion bit to avoid getting completions with error for NOP
WRs. However, NEC is only supported starting with firmware 2.2.232,
so we use constant-sized WRs for older firmware. And, since MLX QPs
only support SEND, we use constant-sized WRs in this case.When stamping during NOP posting, do stamping following setting of the
NOP WQE valid bit.Signed-off-by: Michael S. Tsirkin

When attaching to a stopped process, the RSE must be explicitly

CC: Roland McGrath
Signed-off-by: Tony Luck -
This is base kernel patch for ptrace RSE bug. It's basically a backport
from the utrace RSE patch I sent out several weeks ago. please review.when a thread is stopped (ptraced), debugger might change thread's user
stack (change memory directly), and we must avoid the RSE stored in
kernel to override user stack (user space's RSE is newer than kernel's
in the case). To workaround the issue, we copy kernel RSE to user RSE
before the task is stopped, so user RSE has updated data. we then copy
user RSE to kernel after the task is resummed from traced stop and
kernel will use the newer RSE to return to user.Signed-off-by: Shaohua Li

Some devices - notably dm and md - can change their behaviour in response
to BIO_RW_BARRIER requests. They might start out accepting such requests
but on reconfiguration, they find out that they cannot any more.ext3 (and other filesystems) deal with this by always testing if
BIO_RW_BARRIER requests fail with EOPNOTSUPP, and retrying the write
requests without the barrier (probably after waiting for any pending writes
to complete).However there is a bug in the handling for this for ext3.
When ext3 (jbd actually) decides to submit a BIO_RW_BARRIER request, it
sets the buffer_ordered flag on the buffer head. If the request completes
successfully, the flag STAYS SET.Other code might then write the same buffer_head after the device has been
reconfigured to not accept barriers. This write will then fail, but the
"other code" is not ready to handle EOPNOTSUPP errors and the error will be
treated as fatal.This can be seen without having to reconfigure a device at exactly the
wrong time by putting:if (buffer_ordered(bh))
printk("OH DEAR, and ordered buffer\n");in the while loop in "commit phase 5" of journal_commit_transaction.
If it ever prints the "OH DEAR ..." message (as it does sometimes for
me), then that request could (in different circumstances) have failed
with EOPNOTSUPP, but that isn't tested for.My proposed fix is to clear the buffer_ordered flag after it has been
used, as in the following patch.Signed-off-by: Neil Brown
