2006-11-03V4L/DVB (4751): Fix DBV_FE_CUSTOMISE for card drivers compiled into kernelTrent Piepho
When a front-end is disabled, card drivers that use it are compiled with a stub version of the front-end's attach function. This way they have no references to the front-end's code and don't need it to be loaded. If a card driver is compiled into the kernel, and a front-end is a module, then that front-end is effectively disabled wrt the card driver. In this case, the card driver should get the stub version. This was not happening. The stub vs real attach function selection is changed so that when the front-end is a module the real attach function is only used if the card driver is a module as well. This means a module front-end will be supported by card drivers that are modules and not supported by card drivers compiled into the kernel.

2006-11-02V4L/DVB (4785): Budget-ci: Change DEBIADDR_IR to a safer defaultDavid Härdeman
The IR chip has no address decoding, so the IR data is always present in the high byte when doing a read from the saa7146 chip. This means that the DEBI address used is irrelevant to the IR decoding logic. DEBI addresses 0x1XXX are mapped to the registers on the CI module itself, but only the lowest two bits are actually used (see EN50221, section A.2.2.1), meaning that 0x1234 is equivalent to 0x1000 which maps to register 0 (the data register). A read from the data register is supposed to be preceded by a read from the size register, so some CI modules will be confused (the AlphaCrypt CAM will hang completely). The attached patch changes the address used when reading the IR data to use 0x4000 instead. This is the CI version address, which is a safer default, works with the AlphaCrypt CAM and matches the behaviour of the Windows driver (AFAIK).

2006-11-01[PATCH] powerpc: Eliminate "exceeds stub group size" linker warningPaul Mackerras
It turns out that the linker warnings on 64-bit powerpc about "section blah exceeds stub group size" were being triggered by conditional branches in head_64.S branching to global symbols, whether in head_64.S or in other files. This eliminates the warnings by making some global symbols in head_64.S no longer global, and by rearranging some branches. Signed-off-by: Paul Mackerras <paulus@samba.org> [ Yee-haa.

2006-11-01i386: write IO APIC irq routing entries in correct orderLinus Torvalds

The exception is when we actually want to mask the interrupt, in which case we want to write the low word first to make sure that the high word doesn't change while the interrupt routing is still active.

2006-11-01[POWERPC] Make mmiowb's io_sync preempt safeHugh Dickins
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.

2006-11-01[POWERPC] Make high hugepage areas preempt safeHugh Dickins

2006-11-01[POWERPC] Make current preempt-safeHugh Dickins
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.
