* [PATCH] s390: monotonic_clock interfaceJan Glauber2006-02-011-0/+9
| | | | | | | | | | | Add monotonic_clock interface, used by the hangcheck-timer. On s390 this is the same as sched_clock().

* [PATCH] s390: overflow in sched_clockJan Glauber2006-02-011-1/+1
| | | | | | | | | | | | | | | | | | | | | The least significant bit of the TOD clock value returned by get_clock is the 4096th part of a microsecond. To get to nanoseconds the value needs to be divided by 4096 and multiplied with 1000. The current method multiplies first and then shifts the value to make the result as precise as possible. The disadvantage is that the multiplication with 1000 will overflow shortly after 52 days. sched_clock is used by the scheduler for time stamp deltas, if an overflow occurs between two time stamps the scheduler will get confused. With the patch the problem occurs only after approx. one year, so the chance to run into this overflow is extremly low.

* [PATCH] uml: avoid "CONFIG_NR_CPUS undeclared" bogus error messagesPaolo 'Blaisorblade' Giarrusso2006-02-013-2/+3
| | | | | | | | | | | | | | | | | Olaf Hering <olh@suse.de> Olaf reported UML doesn't build for him with a clear analisys of what happened - we're using NR_CPUS in files linked against glibc headers. Seems like it defines CONFIG_SMP but not CONFIG_NR_CPUS, so we get CONFIG_NR_CPUS undeclared. The fix is to move the declaration away from that header file and move it in asm-um headers, and to add that header where needed.

| | | | | | | | | | | | | | The C99 initialization, with GCC's bad handling, for 6K wide structs (which _aren't_ on the stack), is causing GCC to use 12K for these silly procs with 3 vars.

* [PATCH] VMSPLIT config optionsMark Lord2006-02-012-2/+39
| | | | | | | | | | | | | | | | | | | | | | | | Enable selection of different user/kernel VM splits for i386, including an optimized mode for 1GB physical RAM, which gives the kernel a direct (non HIGHMEM) mapping to the entire 1GB rather than just the first 896MB. There is a similarly a similarly optimized mode for machines with exactly 2GB of physical RAM. This can speed up the kernel by avoiding having to create/destroy temporary HIGHMEM mappings, and by not having to include HIGHMEM support at all on such machines. The flip side is that there's less virtual addressing left for userspace in these alternatives, and some binary-only kernel modules may misbehave unless rebuilt with the same VMSPLIT option as the main kernel image.
