2022-05-12parisc: Merge model and model name into one line in /proc/cpuinfoHelge Deller
commit 5b89966bc96a06f6ad65f64ae4b0461918fcc9d3 upstream. The Linux tool "lscpu" shows the double amount of CPUs if we have "model" and "model name" in two different lines in /proc/cpuinfo. This change combines the model and the model name into one line. Signed-off-by: Helge Deller <deller@gmx.de> Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-08-20parisc: Fix automatic selection of cr16 clocksourceHelge Deller
Commit 54b66800907 (parisc: Add native high-resolution sched_clock() implementation) added support to use the CPU-internal cr16 counters as reliable clocksource with the help of HAVE_UNSTABLE_SCHED_CLOCK. Sadly the commit missed to remove the hack which prevented cr16 to become the default clocksource even on SMP systems. Signed-off-by: Helge Deller <deller@gmx.de> Cc: stable@vger.kernel.org # 4.7+

2013-07-14parisc: delete __cpuinit usage from all usersPaul Gortmaker
The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. This removes all the parisc uses of the __cpuinit macros.

2009-03-31parisc: expose 32/64-bit capabilities in cpuinfoColin Watson
It'd be rather useful for debian-installer if we could get hold of accurate firmware information on whether only 32-bit kernels are supported, only 64-bit kernels, or both; this would allow us to present an accurate menu of kernel packages if more than one is available, rather than the user having to guess. This patch attempts to expose it in cpuinfo. I adjusted pdc_model_capabilities to cope with a potential PDC_INVALID_ARG return as the firmware manual instructs, by assuming 32-bit only. This may be the wrong place for it. I made up user-visible capability names by total fiat and for the moment ignored the other bits that may appear in the capabilities word. I have no PA-RISC machine myself to test on, and no PA experience either, so I rather hope that somebody will kind-heartedly take this and fix it up if needed. I ran it past Dann Frazier on IRC and he said "looks good to me", but I think without testing. Also, this is against the Ubuntu 2.6.28 kernel tree since that's what I had handy and I was a bit tight on disk space to slurp down another tree. Sorry if it's skewed in any relevant way; I'll be happy to adjust if necessary. Thanks in advance! Signed-off-by: Colin Watson <cjwatson@canonical.com> Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
2009-03-16cpumask: Use accessors code.: pariscRusty Russell
Impact: use new API Use the accessors rather than frobbing bits directly. Most of this is in arch code I haven't even compiled, but it is mostly straightforward. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
2009-03-16cpumask: prepare for iterators to only go to nr_cpu_ids/nr_cpumask_bits.: pariscRusty Russell
Impact: cleanup, futureproof In fact, all cpumask ops will only be valid (in general) for bit numbers < nr_cpu_ids. So use that instead of NR_CPUS in various places. This is always safe: no cpu number can be >= nr_cpu_ids, and nr_cpu_ids is initialized to NR_CPUS at boot.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).
