* get rid of NR_OPEN and introduce a sysctl_nr_openEric Dumazet2008-02-065-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | NR_OPEN (historically set to 1024*1024) actually forbids processes to open more than 1024*1024 handles. Unfortunatly some production servers hit the not so 'ridiculously high value' of 1024*1024 file descriptors per process. Changing NR_OPEN is not considered safe because of vmalloc space potential exhaust. This patch introduces a new sysctl (/proc/sys/fs/nr_open) wich defaults to 1024*1024, so that admins can decide to change this limit if their workload needs it.

* read_current_timer() cleanupsAndrew Morton2008-02-064-3/+14
| | | | | | | | | | | | | | | | | | | | - All implementations can be __devinit - The function prototypes were in asm/timex.h but they all must be the same, so create a single declaration in linux/timex.h. - uninline the sparc64 version to match the other architectures - Don't bother #defining ARCH_HAS_READ_CURRENT_TIMER to a particular value.

* remove support for un-needed _extratext sectionRobin Getz2008-02-061-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | When passing a zero address to kallsyms_lookup(), the kernel thought it was a valid kernel address, even if it is not. This is because is_ksym_addr() called is_kernel_extratext() and checked against labels that don't exist on many archs (which default as zero). Since PPC was the only kernel which defines _extra_text, (in 2005), and no longer needs it, this patch removes _extra_text support.

* taskstats scaled time cleanupMichael Neuling2008-02-061-6/+6
| | | | | | | | | | | | | | | | | | | | | | This moves the ability to scale cputime into generic code. This allows us to fix the issue in kernel/timer.c (noticed by Balbir) where we could only add an unscaled value to the scaled utime/stime. This adds a cputime_to_scaled function. As before, the POWERPC version does the scaling based on the last SPURR/PURR ratio calculated. The generic and s390 (only other arch to implement asm/cputime.h) versions are both NOPs. Also moves the SPURR and PURR snapshots closer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The port_sem is already used as a mutex since it's using DECLARE_MUTEX(), but the underlying construct is still a semaphore .. This patch switches it over to a struct mutex.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Downgrade one of the MAC validity checks. If it's one that could be possibly assigned to a physical NIC, then nothing will break. So, emit a warning in this case, but keep the requested MAC.

* | | uml: fix infinite mconsole loopKarol Swietlicki2008-02-051-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch takes care of a problem with the stopping code. The function inside the while condition returns 0 to signify a problem. A problem could be for example a bad command or a bad version of the mconsole client. A bad command would terminate the stopping loop and resume the kernel. This is a problem. A better solution is to make the loop infinite and don't leave it until we are explicitly told to.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | John Reiser noticed that a physical memory region was being mapped twice. This patch fixes that, and it inlines the responsible function, as that had only one caller.
