[ANNOUNCE] linux-libc-headers 2.6.8.0

[Mariusz Mazur]

Available at http://ep09.pld-linux.org/~mmazur/linux-libc-headers/
Changes:
- updated to 2.6.8
- readded ucontext.h - originally thought glibc could handle that, but doesn't 
seem that way (newest hddtemp builds)
- readded unaligned.h (and cleaned it up) - reiserfsprogs' developers found a 
use for it in userland (newest reiserfsprogs builds)
- added and cleaned up (more or less) the sh64 arch
- tried to add missing arm subarch - needs testing I guess
- minor fixes (some ia64 and x86_64 userland conflicts)


This release should have been here a day or two ago weren't it for Murphy's 
laws (the machine that I use for llh development 'broke' yesterday... after 4 
months of uptime :).

Enjoy.

For IA-64 and MIPS, and for any other arch with
variable page sizes, you need something like this:

////////////////////////////////////////
extern int getpagesize(void);

#define PAGE_SIZE ((unsigned long)(getpagesize()))

// This is a gcc statement-expression.
// You might want the __extension__ keyword.
#define PAGE_SHIFT ({          \
  int _PAGE_SIZE = PAGE_SIZE;  \
  (_PAGE_SIZE > 16*1024)       \   
  ?  (_PAGE_SIZE == 32*1024)   \  
     ? 15ul                      \  
     : 16ul                      \  
  :  (_PAGE_SIZE == 8*1024)     \
     ? 13ul                      \  
     :  (_PAGE_SIZE == 4*1024)  \
        ? 12ul                   \
        : 14ul                  \
  ;                           \
})
//////////////////////////////////////////

Never mind that last one. This is nicer:

extern int getpagesize(void);
#define PAGE_SIZE ((unsigned long)getpagesize())
#define PAGE_SHIFT ((unsigned long[]){12,13,14,-1,15,-1,-1,-1,16}[PAGE_SIZE>>13])
