| * | | | [POWERPC] Disallow kprobes on emulate_step and branch_takenGui,Jian2006-11-011-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On powerpc, probing on emulate_step function will crash 2.6.18.1 when it is triggered. When kprobe is triggered, emulate_step() is on its kernel path and will cause recursive kprobe fault. And branch_taken() is called in emulate_step(). This disallows kprobes on both of them.

| * | | | [POWERPC] Make mmiowb's io_sync preempt safeHugh Dickins2006-11-011-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If mmiowb() is always used prior to releasing spinlock as Doc suggests, then it's safe against preemption; but I'm not convinced that's always the case. If preemption occurs between sync and get_paca()->io_sync = 0, I believe there's no problem. But in the unlikely event that gcc does the store relative to another register than r13 (as it did with current), then there's a small danger of setting another cpu's io_sync to 0, after it had just set it to 1. Rewrite ppc64 mmiowb to prevent that. The remaining io_sync assignments in io.h all get_paca()->io_sync = 1, which is harmless even if preempted to the wrong cpu (the context switch itself syncs); and those in spinlock.h are while preemption is disabled.

| * | | | [POWERPC] Make high hugepage areas preempt safeHugh Dickins2006-11-011-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Checking source for other get_paca()->field preemption dangers found that open_high_hpage_areas does a structure copy into its paca while preemption is enabled: unsafe however gcc accomplishes it. Just remove that copy: it's done safely afterwards by on_each_cpu, as in open_low_hpage_areas.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Repeated -j20 kernel builds on a G5 Quad running an SMP PREEMPT kernel would often collapse within a day, some exec failing with "Bad address". In each case examined, load_elf_binary was doing a kernel_read, but generic_file_aio_read's access_ok saw current->thread.fs.seg as USER_DS instead of KERNEL_DS. objdump of filemap.o shows gcc 4.1.0 emitting "mr r5,r13 ... ld r9,416(r5)" here for get_paca()->__current, instead of the expected and much more usual "ld r9,416(r13)"; I've seen other gcc4s do the same, but perhaps not gcc3s. So, if the task is preempted and rescheduled on a different cpu in between the mr and the ld, r5 will be looking at a different paca_struct from the one it's now on, pick up the wrong __current, and perhaps the wrong seg. Presumably much worse could happen elsewhere, though that split is rare. Other architectures appear to be safe (x86_64's read_pda is more limiting than get_paca), but ppc64 needs to force "current" into one instruction.

| * | | | [POWERPC] Use 4kB iommu pages even on 64kB-page systemsLinas Vepstas2006-11-018-81/+80

Thus, it doesn't take much to exhaust all of the available DMA mappings for a high-speed card. This patch changes the iommu allocator to work with its own unique, distinct page size. Although the patch is long, its actually quite simple: it just #defines a distinct IOMMU_PAGE_SIZE and then uses this in all the places that matter. As a side effect, it also dramatically improves network performance on platforms with H-calls on iommu translation inserts/removes (since we no longer call it 16 times for a 1500 bytes packet when the iommu HW is still 4k). In the future, we might want to make the IOMMU_PAGE_SIZE a variable in the iommu_table instance, thus allowing support for different HW page sizes in the iommu itself.

The original cpu_setup function prototype had no arguments, assuming that the reg_setup function would copy the required information into variables which represented the registers. This was silly for e500, since it has 1 register per counter (rather than 3 for all counters), so the code has been restructured to have cpu_setup take the current counter config array as an argument, with op_powerpc_setup() invoking op_powerpc_cpu_setup() through on_each_cpu(), and op_powerpc_cpu_setup() invoking the model-specific cpu_setup function with an argument. The argument is ignored on all other platforms at present. * Fixed a confusing line where a trinary operator only had two arguments Signed-off-by: Andrew Fleming <afleming@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

This patch handles that by using the screen width when that happens. (Also fixes btext.c while at it). - Add detection of the GXT4500 in addition to the GXT2000 for the palette hacks (we use the same hack, palette is linear in register space at offset 0x6000).

Netpoll makes assumptions about the relationship between network device and NAPI that aren't correct on the second port, this will cause the port to never clear work. Most systems, just have single port, so not a big issue. The easy fix is just make the second port, not netpoll capable.

Instead of looking at the hardware's RX/TXstatus ring write pointers to determine when to stop reading from those rings, we should just check every individual RX/TXstatus descriptor's valid bit instead, since there is no other way to distinguish an empty ring from a full ring, and if there is a descriptor waiting, we take the hit of reading the descriptor from memory anyway.

Usually, the cache check and bus check target identifiers have the same address. On Montecito the cache check and bus check target identifiers can be different if a corrected error (ie SBE or unconsumed poison data) was encountered and then an uncorrected error (ie DBE) was consumed. In that case, the cache check target identifier is the physical address of the DBE (that caused the MCA to surface) while the bus check target identifier is the physical address of the SBE. This patch correctly finds the target identifier that triggered the MCA. If there are multiple valid cache target identifiers in the same error record then use the one with the lowest cache level.

* | | | | [MIPS] Fixup migration to GENERIC_TIMEAtsushi Nemoto2006-10-3113-522/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we already moved to GENERIC_TIME, we should implement alternatives of old do_gettimeoffset routines to get sub-jiffies resolution from gettimeofday(). This patch includes: * MIPS clocksource support (based on works by Manish Lachwani). * remove unused gettimeoffset routines and related codes. * remove unised 64bit do_div64_32(). * simplify mips_hpt_init. (no argument needed, __init tag) * simplify c0_hpt_timer_init. (no need to write to c0_count) * remove some hpt_init routines. * mips_hpt_mask variable to specify bitmask of hpt value. * convert jmr3927_do_gettimeoffset to jmr3927_hpt_read. * convert ip27_do_gettimeoffset to ip27_hpt_read. * convert bcm1480_do_gettimeoffset to bcm1480_hpt_read. * simplify sb1250 hpt functions. (no need to subtract and shift) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

This could cause io stalls until that process issued io again. Fix it up by putting the rr_list add handling into cfq_add_rq_rb(), identical to how pruning is handled in cfq_del_rq_rb(). This fixes a hang reproducible with fsx-linux. Signed-off-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This changes all of the callers of make_ipr_irq to allocate a static structure containing the IPR data which is then passed to make_ipr_irq. This removes the need for make_ipr_irq to allocate any additional space for the IPR information. Signed-off-by: Jamie Lenehan <lenehan@twibble.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The following function is called for each element of each chain: static void ip6fl_fl_seq_show(struct seq_file *seq, struct ip6_flowlabel *fl) { while(fl) { seq_printf... fl = fl->next; } } Thus, objects can appear mutliple times when reading /proc/net/ip6_flowlabel, as the above is called for each element in the chain. The solution is to remove the while() loop from the above, and traverse each chain exactly once, per the patch below. This also removes the ip6fl_fl_seq_show() function, which does nothing else.
