      sparc: Fix mremap address range validation. · 94d149c3
      David S. Miller authored 
      
Just like mmap, we need to validate address ranges regardless
of MAP_FIXED.

sparc{,64}_mmap_check()'s flag argument is unused, remove.

Based upon a report and preliminary patch by
Jan Lieskovsky <jlieskov@redhat.com>

      Make 'cond_resched()' nullification depend on PREEMPT_BKL · c714a534
      Linus Torvalds authored 
      
Because it's not correct with a non-preemptable BKL and just causes
PREEMPT kernels to have longer latencies than non-PREEMPT ones (which is
obviously not the point of it at all).

Of course, that config option actually got removed as an option earlier,
so for now this basically disables it entirely, but if BKL preemption is
ever resurrected it will be a meaningful optimization.  And in the
meantime, it at least documents the intent of the code, while not doing
the wrong thing.

      Fix up 'need_resched()' definition · 9404ef02
      Linus Torvalds authored 
      
We should not go through the task pointer to get at the thread info,
since it's usually cheaper to just access the thread info directly.

So don't make the code look up 'current', when we can just use the
thread info accessor functions directly.  This generally avoids one
level of indirection and tends to work better together with code that
also looks at other thread flags (eg preempt_count).

      types: s390: fix #ifdef reversal in <asm-s390/types.h> · 2ccdcfee
      H. Peter Anvin authored 
      
The #ifdef for the integer types was reversed; the standard pattern in
these files are:

#ifndef __s390x__
/* 32-bit code */
#else
/* 64-bit code */
#endif

Stick with the original pattern, but make sure the 32-bit code
actually comes first!

56a6b1eb was a bit too conservative and
left __ilog2 around which is only used as an internal function for other

__ilog2() for non MIPS32/MIPS64 cpus and use generic __fls bitop code for
these cpus.

      [MIPS] Pb1200/DBAu1200 code style cleanup · c3d1d5c8
      Sergei Shtylyov authored 
      
Fix several errors and warnings given by checkpatch.pl:

- use of C99 // comments;

- initialization of a 'static' variable to 0;

- space after opening and before closing parentheses;

- missing space between 'for' and opening parenthesis;

- macros with complex values not enclosed in parentheses;

- printk() without KERN_* facility level;

- unnecessary braces for single-statement block;

- using simple_strtol() where strict_strtol() could be used;

- line over 80 characters.

In addition to these changes, also do the following:

- mention DBAu1200 board in the Makefile;

- replace the group of #include/#ifdef directives by a single
  #include <au1xxx.h> since this header contains the needed stuff;

- properly indent the blocks;

- insert spaces between operator and its operands, remove excess spaces
  there;

- remove needless parentheses and add some for clarity;

- replace numeric literals/expressions with the matching macros;

- remove space after the type cast's closing parenthesis;

- reduce pb1200_setup_cascade() to the single 'return' statement;

- reduce the number of printed empty lines in the so-called CPLD
  workaround;

- remove #undef AU1X00_EXTERNAL_INT since that macro is not defined
  anywhere;

- replace spaces after the macro name with tabs in the #define directives;

- remove excess tabs after the macro name in the #define directives;

- fix typo in the BCSR_RESETS_PWMR1mUX macro's name;

- group all Pb1200 PCMCIA definitions together;

- put the function's result type and name/parameters on the same line;

- insert missing and remove excess new lines;

- make the multi-line comment style consistent with the kernel style
  elsewhere by adding empty first line and/or adding space/asterisk on
  their left side;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- combine some comments;

- update MontaVista copyright;

- remove Pete Popov's old email address...
