2006-06-01[MIPS] Remove support for sysmips(2) SETNAME and MIPS_RDNVRAM operations.Ralf Baechle1-24/+0
SETNAME only had a minor defect but probably never had a user and MIPS_RDNVRAM was unimplemented anyway. Signed-off-by: Ralf Baechle <[email protected]>

2006-04-27[MIPS] Fix branch emulation for floating-point exceptions.Ralf Baechle1-1/+1
In the branch emulation for floating-point exceptions, __compute_return_epc must determine for bc1f et al which condition code bit to test. This is based on bits <4:2> of the rt field. The switch statement to distinguish bc1f et al needs to use only the two low bits of rt, but the old code tests on the whole rt field. This patch masks off the proper bits.

2006-04-27[MIPS] Cleanup inode->r_dev usage.Ralf Baechle2-9/+8

2006-04-26[PATCH] fix mips sys32_p{read,write}Al Viro1-62/+2
Switched to use of sys_pread64()/sys_pwrite64() rather than keep duplicating their guts; among the little things that had been missing there were such as ret = security_file_permission (file, MAY_READ); Gotta love the LSM robustness, right?

2006-04-19[MIPS] Rewrite all the assembler interrupt handlers to C.Ralf Baechle2-0/+16
Saves like 1,600 lines of code, is way easier to debug, compilers frequently do a better job than the cut and paste type of handlers many boards had. And finally having all the stuff done in a single place also means alot of bug potencial for the MT ASE is gone. The only surviving handler in assembler is the DECstation one; I hope Maciej will rewrite it. Signed-off-by: Ralf Baechle <[email protected]>

2006-04-11[PATCH] No arch-specific strpbrk implementationsKyle McMartin1-1/+0
While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't being exported from lib/string.c. Investigating further, I noticed a changeset that removed its export and added it to _ksyms.c on a few more architectures. The justification was that "other arches do it." I think this is wrong, since no architecture currently defines __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it themselves. Therefore, consolidate the export to lib/string.c.

2006-03-27[PATCH] unify PFN_* macrosDave Hansen1-8/+1
Just about every architecture defines some macros to do operations on pfns. They're all virtually identical. This patch consolidates all of them. One minor glitch is that at least i386 uses them in a very skeletal header file. To keep away from #include dependency hell, I stuck the new definitions in a new, isolated header. Of all of the implementations, sh64 is the only one that varied by a bit. It used some masks to ensure that any sign-extension got ripped away before the arithmetic is done. This has been posted to that sh64 maintainers and the development list. Compiles on x86, x86_64, ia64 and ppc64.

2006-03-25[PATCH] sys_alarm() unsigned signed conversion fixupThomas Gleixner1-21/+1
alarm() calls the kernel with an unsigend int timeout in seconds. The value is stored in the tv_sec field of a struct timeval to setup the itimer. The tv_sec field of struct timeval is of type long, which causes the tv_sec value to be negative on 32 bit machines if seconds > INT_MAX. Before the hrtimer merge (pre 2.6.16) such a negative value was converted to the maximum jiffies timeout by the timeval_to_jiffies conversion. It's not clear whether this was intended or just happened to be done by the timeval_to_jiffies code. hrtimers expect a timeval in canonical form and treat a negative timeout as already expired. This breaks the legitimate usage of alarm() with a timeout value > INT_MAX seconds. For 32 bit machines it is therefor necessary to limit the internal seconds value to avoid API breakage. Instead of doing this in all implementations of sys_alarm the duplicated sys_alarm code is moved into a common function in itimer.c Signed-off-by: Thomas Gleixner <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2006-03-23[PATCH] more for_each_cpu() conversionsAndrew Morton2-8/+6
When we stop allocating percpu memory for not-possible CPUs we must not touch the percpu data for not-possible CPUs at all. The correct way of doing this is to test cpu_possible() or to use for_each_cpu(). This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very few instances of this bug, if any. But the patch converts lots of open-coded test to use the preferred helper macros.

From Dave Johnson <[email protected]>: * do_timer() expects the arch-specific handler to take the lock as it modifies jiffies[_64] and xtime. * writing timerhi/lo in timer_interrupt() will mess up fixed_rate_gettimeoffset() which reads timerhi/lo. Signed-off-by: Ralf Baechle <[email protected]>

2006-03-09[MIPS] Discard .exit.text at runtime.Ralf Baechle1-1/+3
At times gcc will place bits of __exit functions into .rodata. If compiled into the kernle itself we used to discard .exit.text - but not the bits left in .rodata.
