2008-07-15[MIPS] unexport {allocate,free}_irqnoDmitri Vorobiev
The following routines allocate_irqno() free_irqno() seem not to be used outside of the core kernel code, hence exporting these functions is pointless. This patch removes the export. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@movial.fi> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-07-15[MIPS] fix sparse warning about setup_early_printk()Dmitri Vorobiev
This patch fixes the following sparse warning: <<<<<<<< arch/mips/kernel/early_printk.c:35:13: warning: symbol 'setup_early_printk' was not declared. Should it be static? <<<<<<<< The fix is to define a prototype of the setup_early_printk() function and to include the appropriate header into arch/mips/kernel/early_printk.c.

2008-07-15[MIPS] Remove obsolete isa_slot_offsetMaciej W. Rozycki
The isa_slot_offset variable and its __ISA_IO_base macro is not used anywhere anymore. It does not look like a decent interface per today's standards either.

2008-07-03[MIPS] cevt-txx9: Reset timer counter on initializationAtsushi Nemoto

Existing code in there (get_tty(), etc.) is both severely racy *and* pointless: ioctls in question have Linux equivalents and there's no need to play silly buggers in irix_ioctl() - just need to replace arguments and, in case of TIOCGSID, deal with API differences - Linux one expects pid_t __user * while Irix one does unsigned long __user *.

2008-05-01remove div_long_long_remRoman Zippel
x86 is the only arch right now, which provides an optimized for div_long_long_rem and it has the downside that one has to be very careful that the divide doesn't overflow. The API is a little akward, as the arguments for the unsigned divide are signed. The signed version also doesn't handle a negative divisor and produces worse code on 64bit archs. There is little incentive to keep this API alive, so this converts the few users to the new API.
