2008-07-15[MIPS] MSC01: Cleanup configuration.Ralf Baechle1-1/+1
This shouldn't depend on CONFIG_MIPS_BOARDS_GEN which is about to go away. Signed-off-by: Ralf Baechle <[email protected]>
2008-07-15[MIPS] Replace use of print_symbol with new %sP pointer format.Ralf Baechle2-10/+9

2008-07-15[MIPS] i8253: make the pit_clockevent variable staticDmitri Vorobiev1-1/+1
The pit_clockevent symbol is needlessly defined global. This patch makes that variable static. Spotted by sparse. Compile-tested using Malta defconfig. Signed-off-by: Dmitri Vorobiev <[email protected]> Signed-off-by: Ralf Baechle <[email protected]>
2008-07-15[MIPS] IRIX: Goodbye and thanks for all the fishRalf Baechle9-5751/+0
Never terribly functional or popular, plagued by hard to fix bugs the time to say goodbye has more than arrived. Signed-off-by: Ralf Baechle <[email protected]>
2008-07-15[MIPS] unexport {allocate,free}_irqnoDmitri Vorobiev1-4/+0
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 <[email protected]> Signed-off-by: Ralf Baechle <[email protected]>
2008-07-15[MIPS] fix sparse warning about setup_early_printk()Dmitri Vorobiev2-5/+3
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. Rozycki1-7/+0
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. Remove both including all places of initialization. Signed-off-by: Maciej W. Rozycki <[email protected]> Signed-off-by: Ralf Baechle <[email protected]>

2008-07-03[MIPS] cevt-txx9: Reset timer counter on initializationAtsushi Nemoto1-0/+3
The txx9_tmr_init() will not clear a timer counter register in a certain case. The counter register is cleared on 1->0 transition of TCE bit if CRE=1. So just clearing the TCE bit is not enough. Signed-off-by: Atsushi Nemoto <[email protected]> Signed-off-by: Ralf Baechle <[email protected]>

2008-06-26on_each_cpu(): kill unused 'retry' parameterJens Axboe2-4/+4
It's not even passed on to smp_call_function() anymore, since that was removed. So kill it. Acked-by: Jeremy Fitzhardinge <[email protected]> Reviewed-by: Paul E. McKenney <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2008-06-26smp_call_function: get rid of the unused nonatomic/retry argumentJens Axboe1-2/+2
It's never used and the comments refer to nonatomic and retry interchangably. So get rid of it. Acked-by: Jeremy Fitzhardinge <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2008-06-26mips: convert to generic helpers for IPI function callsJens Axboe2-131/+11
This converts mips to use the new helpers for smp_call_function() and friends, and adds support for smp_call_function_single(). Not tested, but it compiles. mips shares the same IPI for smp_call_function() and smp_call_function_single(), since not all mips platforms have enough available IPIs to support seperate setups.

2008-06-05[MIPS] Fix check for valid stack pointer during backtraceThomas Bogendoerfer1-7/+9
The newly added check for valid stack pointer address breaks at least for 64bit kernels. Use __get_user() for accessing stack content to avoid crashes, when doing the backtrace. Signed-off-by: Thomas Bogendoerfer <[email protected]> Signed-off-by: Ralf Baechle <[email protected]>

2008-05-12[MIPS] Add empty argument parenthesis to GCC_IMM_ASMRalf Baechle1-1/+1
This is to clarify that GCC_IMM_ASM does not take an argument as the context of the macro's invocation seems to imply. As suggested by Maciej W. Rozycki ([email protected]). Signed-off-by: Ralf Baechle <[email protected]>

2008-05-12[MIPS] IRIX: Handle do_brk() error return correctly.Ralf Baechle1-4/+7
do_brk's return value was stored in an unsigned long variable before being tested for less than zero making the test always fail. Also do_brk's called irix_map_prda_page wasn't forwarding do_brk() success. Bug checking the return value of do_brk() and initial fix for it found by Roel Kluin <[email protected]>.

2008-05-01[PATCH] remove horrors with irix tty ioctls handlingAl Viro1-46/+9
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 Zippel2-4/+6
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.
