The following patch to the common part of the Siemens Gigaset driver
prevents it from trying to send the +++ break sequence if the device has
been disconnected, and removes a couple of assignments which didn't have
any effect.Signed-off-by: Tilman Schmidt

The following patch to the Siemens Gigaset base driver adds graceful
recovery for some frequently encountered error conditions, by retrying
failed control requests (eg. stalled control pipe), and by closing and
reopening the AT command channel when it appears to be stuck.Signed-off-by: Tilman Schmidt

Kernel panic - not syncing: Fatal exception in interruptThat oops took me to the "ackqueue" implementation in capi.c. The crash
occured in capincci_add_ack() (auto-inlined by the compiler).I read the code a bit and finally decided to replace the custom linked list
implementation (struct capiminor->ackqueue) by a struct list_head. That
did not solve the crash, but produced the following interresting oops:Unable to handle kernel paging request at virtual address 00200200

LIST_POISON2. I thought about some race condition, but as this is an UP
system, it leads to questions on how it can happen. If we look at EFLAGS:
00010202, we see that interrupts are enabled at the time of the crash
(eflags & 0x200).Finally, I don't understand all the capi code, but I think that
handle_minor_send() is racing somehow against capi_recv_message(), which
call both capiminor_del_ack(). So if an IRQ occurs in the middle of
capiminor_del_ack() and another instance of it is invoked, it leads to
linked list corruption.I came up with the following patch. With this, I could not reproduce the
crash anymore. Clearly, this is not the correct fix for the issue. As this
seems to be some locking issue, there might be more locking issues in that
code. For example, doesn't the whole struct capiminor have to be locked
somehow?Cc: Carsten Paeth

As part of the i386 conversion to the generic timekeeping infrastructure, this
introduces a new tsc.c file. The code in this file replaces the TSC
initialization, management and access code currently in timer_tsc.c (which
will be removed) that we want to preserve.The code also introduces the following functionality:
o tsc_khz: like cpu_khz but stores the TSC frequency on systems that do not
change TSC frequency w/ CPU frequencyo check/mark_tsc_unstable: accessor/modifier flag for TSC timekeeping
usabilityo minor cleanups to calibration math.
This patch also includes a one line __cpuinitdata fix from Zwane Mwaikambo.

John's about to nuke x86's monotonic clock without grepping for it first. The
patch lamely borrows the ppc64 code for x86.hangcheck-timer shouldn't be doing it this way
a) HAVE_MONOTONIC should be CONFIG_MONOTONIC_CLOCK and it should be defined
in arch/xxx/Kconfig.b) That ifdef tangle shouldn't be in hangcheck-timer.c. It should be using
arch-provided helper functions, which CONFIG_MONOTONIC_CLOCK-enabling
architectures implement in arch/something.cCc: john stultz

This patch series replaces the old non-generic Hardware Random Number
Generator support by a fully generic RNG API.This makes it possible to register additional RNGs from modules. With this
patch series applied, Laptops with a bcm43xx chip (PowerBook) have a HW RNG
available now.Additionally two new RNG drivers are added for the "ixp4xx" and "omap"
devices. (Written by Deepak Saxena). This patch series includes the old
patches by Deepak Saxena.The old x86-rng driver has beed split.
The userspace RNG daemon can later be updated to select the RNG through
/sys/class/misc/hw_random/ for convenience. For now it is sufficient to use
cat and echo -n on the sysfs attributes.Signed-off-by: Michael Buesch

Magic sysrq fails to work on many keyboards, particulary most of notebook
keyboards. This patch fixes it.The idea is quite simple: Discard the SysRq break code if Alt is still being
held down. This way the broken keyboard can send the break code (or the user
with a normal keyboard can release the SysRq key) and the kernel waits until
the next key is pressed or the Alt key is released.Signed-off-by: Pavel Machek
