2007-10-29[MIPS] time: Fix cevt-r4k.c for 64-bit kernelAtsushi Nemoto
The expression "(long)(read_c0_count() - cnt)" can never be a negative value on 64-bit kernel. Cast to "int" before comparison. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-10-29[MIPS] Sibyte: Delete {sb1250,bcm1480}_steal_irq().Ralf Baechle
They break the timer interrupt initialization and only seem to be a kludge for initialization happening in the wrong order. Further testing done by Thiemo confirms the suspicion that the other invocations also seem to have useless. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-10-29[MIPS] txx9tmr clockevent/clocksource driverAtsushi Nemoto
Convert jmr3927_clock_event_device to more generic txx9tmr_clock_event_device which supports one-shot mode. The txx9tmr_clock_event_device can be used for TX49 too if the cp0 timer interrupt was not available. Convert jmr3927_hpt_read to txx9_clocksource driver which does not depends jiffies anymore. The txx9_clocksource itself can be used for TX49, but normally TX49 uses higher precision clocksource_mips.

2007-10-29[MIPS] SMTC: Allow control over TC assignment to vpe0.Kevin D. Kissell
Modify the SMTC initialization code to allow boot-time specification not only of how many VPEs and TCs to use, but also how many TCs out of the allowed pool are to be bound to VPE 0. The new boot option is "vpe0tcs=N", where N is an integer. Using it in combination with the existing options allows arbitrary assignments across the 2 VPEs of a 34K. e.g. "maxtcs=3 vpe0tcs=1" forces VPE0 to have 1 TC, while VPE1 has 2, and "maxtcs=4 vpe0tcs=3" forces VPE0 to have 3 TCs, while VPE1 gets 1. If no vpe0tcs option is specified, the traditional algorithm of evenly dividing TCs between available VPEs, with the odd "slop" going to VPE0, is retained. The reason for doing this is to allow a finer balancing of TCs which can handle I/O interrupts on Malta (those on VPE 0) and those which cannot. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-10-27x86: Dump filtering supports x86_64 sparsememKen'ichi Ohmichi
This patch adds the symbol "init_level4_pgt" to the vmcoreinfo data so that makedumpfile (dump filtering command) supports x86_64 sparsemem kernel of linux-2.6.24. makedumpfile creates a small dumpfile by excluding unnecessary pages for the analysis. It checks attributes in page structures and distinguishes necessary pages and unnecessary ones. To check them, makedumpfile gets the vmcoreinfo data which has the minimum debugging information only for dump filtering. For older x86_64 kernel (linux-2.6.23 or before), makedumpfile translates the virtual address of page structure into physical address by subtracting PAGE_OFFSET from virtual address, but this translation isn't effective for linux-2.6.24 sparsemem kernel, because its page structures are in virtual memmap area. makedumpfile should translate their virtual address by 4-levels paging and it needs the symbol "init_level4_pgt".

2007-10-27x86: Fix boot protocol KEEP_SEGMENTS check.Eric W. Biederman
The kernel only ever supports 1 version of the boot protocol so there is no need to check the boot protocol revision to see if a feature is supported. Both x86 and x86_64 support the same boot protocol so we need to implement the KEEP_SEGMENTS on x86_64 as well. It isn't just paravirt bootloaders that could use this functionality.

2007-10-27x86: voyager: fix bogus conversion to per_cpu for boot_cpu_infoJames Bottomley
There were two problems. Firstly, someone forgot the struct keyword in front of cpuinfo_x86, so I take it this wasn't even compile checked. Secondly, the actual definition has this as a SHARED_ALIGNED, so the definitions mismatch.

2007-10-25x86 setup: sizeof() is unsigned, unbreak comparisonsH. Peter Anvin
We use signed values for limit checking since the values can go negative under certain circumstances. However, sizeof() is unsigned and forces the comparison to be unsigned, so move the comparison into the heap_free() macros so we can ensure it is a signed comparison. Signed-off-by: H.
