This patch fixed bugzilla #12965:
https://bugzilla.kernel.org/show_bug.cgi?id=12965
The original code contains some inproper use of sprintf
function where a buffer is used both as input string
as well as output string. It should remember the written
bytes in the previous and use that as the offset for
later writing. Also replace sprintf with snprintf.

Even though the anomaly sheet says that the the bootrom is fixed, tests
have shown that the fix itself does not handle all cases. So until we
get a ROM update, assume the reset code is still broken and we need to
handle things ourselves.

When CoreB wakes up, it needs to read variables that CoreA might have

Not all 64-bit systems require ISA-style DMA, so allow it to be
configurable. x86 utilizes the generic ISA DMA allocator from
kernel/dma.c, so require it only when CONFIG_ISA_DMA_API is enabled.
Disabling CONFIG_ISA_DMA_API is dependent on x86_64 since those machines
do not have ISA slots and benefit the most from disabling the option (and
on CONFIG_EXPERT as required by H. Peter Anvin).
When disabled, this also avoids declaring claim_dma_lock(),
release_dma_lock(), request_dma(), and free_dma() since those interfaces
will no longer be provided.

The generic floppy disk driver utilizies the interface provided by
CONFIG_ISA_DMA_API, specifically claim_dma_lock(), release_dma_lock(),
request_dma(), and free_dma(). Thus, there's a strict dependency on the
config option and the driver should only be loaded if the kernel supports
ISA-style DMA.

One of our users reported that when a user-level program SIGSEGVs under
UML kernel, the resulting core dump is not very usable.
I have reproduced that with the latest kernel:
make ARCH=um defconfig; make ARCH=um
Run the resulting kernel, then "inside" run this program:
#include <pthread.h>
void *fn(void *p)
{
abort();
}
int main()
{
pthread_t tid;
pthread_create(&tid, 0, fn, 0);
pthread_join(tid, 0);
return 0;
}
Analyze the coredump with GDB. Here is what you'll see:
sudo gdb -q -ex 'set solib-absolute-prefix ../root_fs' -ex 'file ../root_fs/var/tmp/mt-abort' -ex 'core ../root_fs/var/tmp/core.762'

Examining the core shows that NT_PRSTATUS notes for all threads other than
the one that crashed are zeroed out.
I believe this is happening because neither ELF_CORE_COPY_TASK_REGS nor
task_pt_regs are defined under ARCH=um, and so elf_core_copy_task_regs()
becomes a no-op.
Attached patch fixes this for SUBARCH={x86_64,i386}.

from a single node for their kernel stack and task struct.
This patch suite creates kthread_create_on_cpu(), adding a 'cpu' parameter

APEI ERST firmware interface and implementation has no multiple users
in mind. For example, if there is four records in storage with ID: 1,
2, 3 and 4, if two ERST readers enumerate the records via
GET_NEXT_RECORD_ID as follow,
reader 1 reader 2
1
2
3
4
-1
-1
where -1 signals there is no more record ID.
Reader 1 has no chance to check record 2 and 4, while reader 2 has no
chance to check record 1 and 3. And any other GET_NEXT_RECORD_ID will
return -1, that is, other readers will has no chance to check any
record even they are not cleared by anyone.
This makes raw GET_NEXT_RECORD_ID not suitable for used by multiple
users.
To solve the issue, an in-memory ERST record ID cache is designed and
implemented. When enumerating record ID, the ID returned by
GET_NEXT_RECORD_ID is added into cache in addition to be returned to
caller. So other readers can check the cache to get all record ID
available.

This patch moves the platform data definition from
arch/arm/plat-pxa/include/plat/i2c.h to include/linux/i2c/pxa-i2c.h so
it can be accessed from x86 the same way as on ARM.
This change should make no functional change to the PXA code. The move
is verified by building the following defconfigs:
cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig
imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig
raumfeld_defconfig magician_defconfig mmp2_defconfig pxa168_defconfig

It is frequently useful to sync a single file system, instead of all
mounted file systems via sync(2):
- On machines with many mounts, it is not at all uncommon for some of
them to hang (e.g. unresponsive NFS server). sync(2) will get stuck on
those and may never get to the one you do care about (e.g., /).
- Some applications write lots of data to the file system and then
want to make sure it is flushed to disk. Calling fsync(2) on each
file introduces unnecessary ordering constraints that result in a large
amount of sub-optimal writeback/flush/commit behavior by the file
system.
There are currently two ways (that I know of) to sync a single super_block:
- BLKFLSBUF ioctl on the block device: That also invalidates the bdev
mapping, which isn't usually desirable, and doesn't work for non-block
file systems.
- 'mount -o remount,rw' will call sync_filesystem as an artifact of the
current implemention. Relying on this little-known side effect for
something like data safety sounds foolish.
Both of these approaches require root privileges, which some applications
do not have (nor should they need?) given that sync(2) is an unprivileged
operation.
This patch introduces a new system call syncfs(2) that takes an fd and
syncs only the file system it references. Maybe someday we can
$ sync /some/path
and not get
sync: ignoring all arguments
The syscall is motivated by comments by Al and Christoph at the last LSF.
syncfs(2) seems like an appropriate name given statfs(2).
A similar ioctl was also proposed a while back, see

In some cases during a threaded core dump not all the threads will have
a full register set. This happens when the signal causing the core dump
races with a thread exiting. The race happens when the exiting thread
has entered the kernel for the last time before the signal arrives, but
doesn't get far enough through the exit code to avoid being included
in the core dump.
So we get a thread included in the core dump which is never going to go
out to userspace again and only has a partial register set recorded
Normally we would catch each thread as it is about to go into userspace
and capture the full register set then.
However, this exiting thread is never going to go out to userspace
again, so we have no way to capture its full register set. It doesn't
really matter, though, as this is a thread which is effectively
already dead.
So instead of hitting a BUG() in this case (a really bad choice of
action in the first place), we use a poison value for the register
values.
