[PATCH] s390: fix sclp memory corruption in tty pages list
When the sclp interface takes very long to serve a request, the sclp core
driver will report a failed request to the sclp tty driver even though the
request is still being processed by the sclp interface. Eventually the sclp
interface completes the request and updates some fields in the request buffer
which leads to a corrupted tty pages list. The next time function
sclp_tty_write_room is called, the corrupted list will be traversed, resulting
in an oops.

[PATCH] select: fix returned timeval
With David Woodhouse <dwmw2@infradead.org>
select() presently has a habit of increasing the value of the user's

We were writing back a timeout larger than the original. We _deliberately_
round up, since we know we must wait at _least_ as long as the caller asks
us to.
The patch adds a couple of helper functions for magnitude comparison of
timespecs and of timevals, and uses them to prevent the various poll and
select functions from returning a timeout which is larger than the one which
was passed in.
The patch also fixes a bug in compat_sys_pselect7(): it was adding the new
timeout value to the old one and was returning that. It should just return
the new timeout value.
(We have various handy timespec/timeval-to-from-nsec conversion functions in

The IBM Summit 3 chipset doesn't implement the HPET timer replacement

both PIT for the interrupt and HPET counters for the time keeping. That
was already implemented, but didn't work properly because it was still
using the last interrupt offset in HPET. This resulted in x460 not

Shouldn't affect any other machine because they either use full HPET mode

The *at patches introduced fstatat and, due to inusfficient research, I

on 32-bit platforms we don't have all the information needed to implement
fstatat64.
This patch modifies the code to pass up 64-bit information if
__ARCH_WANT_STAT64 is defined. I renamed the syscall entry point to make
this clear. Other archs will continue to use the existing code. On x86-64
the compat code is implemented using a new sys32_ function. this is what
is done for the other stat syscalls as well.
This patch might break some other archs (those which define
__ARCH_WANT_STAT64 and which already wired up the syscall). Yet others
might need changes to accomodate the compatibility mode. I really don't
want to do that work because all this stat handling is a mess (more so in
glibc, but the kernel is also affected). It should be done by the arch
maintainers. I'll provide some stand-alone test shortly. Those who are
eager could compile glibc and run 'make check' (no installation needed).

[PATCH] kexec: fix in free initrd when overlapped with crashkernel region
It is possible that the reserved crashkernel region can be overlapped with

region is freed, the second kernel memory will not be contiguous. The
Kexec_load can cause an oops since there is no contiguous memory to write
the second kernel or this memory could be used in the first kernel itself
and may not be part of the dump. For example, on powerpc, the initrd is
located at 36MB and the crashkernel starts at 32MB. The kexec_load caused
panic since writing into non-allocated memory (after 36MB). We could see
the similar issue even on other archs.
One possibility is to move the initrd outside of crashkernel region. But,
the initrd region will be freed anyway before the system is up. This patch
fixes this issue and frees only regions that are not part of crashkernel

The samples (group of 4) I got for "maximum recorded imbalance" on a 2x2

Hackbench raw performance is down around 15% with smpnice (but that in
itself isn't a huge deal because it is just a benchmark). However, the
samples show that the imbalance passed into move_tasks is increased by
about a factor of 10-30. I think this would also go some way to explaining
latency blips turning up in the balancing code (though I haven't actually

Patch from Lennert Buytenhek
The ixdp2x01 pci init call doesn't check whether it's really running
on an ixdp2x01, making it impossible to compile one kernel that works
on both the ixdp2x01 and another ixp2000 board.
