* [PATCH] Fix typo in drivers/isdn/hisax/q931.cEric Sesterhenn2006-06-261-2/+2
| | | | | | | | | | | | This fixes coverity bug #517. Since IESIZE is greater than IESIZE_NI1 we might run past the end of ielist_ni1. This fixes it by using the proper IESIZE_NI1 define.

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?

* [PATCH] Time: i386 Conversion - part 2: Rework TSC Supportjohn stultz2006-06-261-0/+9
| | | | | | | | | | | | | | | | | | | | | | | 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 frequency o check/mark_tsc_unstable: accessor/modifier flag for TSC timekeeping usability o minor cleanups to calibration math. This patch also includes a one line __cpuinitdata fix from Zwane Mwaikambo.

* [PATCH] Remove old HW RNG supportMichael Buesch2006-06-263-714/+0
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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.

Having this as a separate stuff makes harder to configure it, since there are some tda9887 options that are tuner-dependent and should be bound into tuner-types structures. This patch merges tda9887 module into tuner. More work is required to make tuner-types to properly use it. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
