2008-12-30cpumask: smp_call_function_many()Rusty Russell
Impact: Implementation change to remove cpumask_t from stack. Actually change smp_call_function_mask() to smp_call_function_many(). We avoid cpumasks on the stack in this version. (S390 has its own version, but that's going away apparently). We have to do some dancing to figure out if 0 or 1 other cpus are in the mask supplied and the online mask without allocating a tmp cpumask. It's still fairly cheap. We allocate the cpumask at the end of the call_function_data structure: if allocation fails we fallback to smp_call_function_single rather than using the baroque quiescing code (which needs a cpumask on stack). (Thanks to Hiroshi Shimamoto for spotting several bugs in previous versions!)

2008-12-30cpumask: make set_cpu_*/init_cpu_* out-of-lineRusty Russell
They're only for use in boot/cpu hotplug code anyway, and this avoids the use of deprecated cpu_*_map. Stephen Rothwell points out that gcc 4.2.4 (on powerpc at least) didn't like the cast away of const anyway: include/linux/cpumask.h: In function 'set_cpu_possible': include/linux/cpumask.h:1052: warning: passing argument 2 of 'cpumask_set_cpu' discards qualifiers from pointer target type So this kills two birds with one stone.

2008-12-30cpumask: make cpumask.h eat its own dogfood.Rusty Russell
Changes: 1) cpumask_t to struct cpumask, 2) cpus_weight_nr to cpumask_weight, 3) cpu_isset to cpumask_test_cpu, 4) ->bits to cpumask_bits() 5) cpu_*_map to cpu_*_mask. 6) for_each_cpu_mask_nr to for_each_cpu Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30cpumask: switch over to cpu_online/possible/active/present_mask: coreRusty Russell
Impact: cleanup This implements the obsolescent cpu_online_map in terms of cpu_online_mask, rather than the other way around. Same for the other maps. The documentation comments are also updated to refer to _mask rather than _map. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
2008-12-30bitmap: fix seq_bitmap and seq_cpumask to take const pointerRusty Russell
Impact: cleanup seq_bitmap just calls bitmap_scnprintf on the bits: that arg can be const. Similarly, seq_cpumask just calls seq_bitmap. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30bitmap: test for constant as well as small size for inline versionsRusty Russell
Impact: reduce text size bitmap_zero et al have a fastpath for nbits <= BITS_PER_LONG, but this should really only apply where the nbits is known at compile time. This only saves about 1200 bytes on an allyesconfig kernel, but with cpumasks going variable that number will increase. text data bss dec hex filename 35327852 5035607 6782976 47146435 2cf65c3 vmlinux-before 35326640 5035607 6782976 47145223 2cf6107 vmlinux-after Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30cpumask: make CONFIG_NR_CPUS always valid.Rusty Russell
Impact: cleanup Currently we have NR_CPUS, which is 1 on UP, and CONFIG_NR_CPUS on SMP. If we make CONFIG_NR_CPUS always valid (and always 1 on !SMP), we can skip the middleman. This also allows us to find and check all the unaudited NR_CPUS usage as we prepare for v. large NR_CPUS. To avoid breaking every arch, we cheat and do this for the moment in the header if the arch doesn't. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>

2008-12-29V4L/DVB (9764): em28xx: Add support for suspend the device when not usedMauro Carvalho Chehab
Several chips may be turned off when the device is not used, like audio, video and dvb demods. This patch adds a gpio callback at the core structs to allow turning off such devices. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9763): em28xx: fix gpio settingsMauro Carvalho Chehab
A previous changeset moved gpio from em28xx struct into em28xx_board. However, the driver were not updated to properly honor those gpio's. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9762): em28xx: fix tuner absent entriesMauro Carvalho Chehab
Before this patch, several devices without tuner were kept the value 0 for tuner_type. However, this means TUNER_TEMIC_PAL. Replace those entries for the proper TUNER_ABSENT value. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9761): em28xx: replace magic numbers for mux aliasesMauro Carvalho Chehab

2008-12-29V4L/DVB (9760): em28xx: move gpio lines into board table descriptionMauro Carvalho Chehab
Instead of a large, ugly switch specifying the gpio tables for each device, let's move it into the boards struct. This also helps to see what boards have already the gpio's for DVB. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-12-29V4L/DVB (9758): em28xx: replace some magic by register descriptions where knownMauro Carvalho Chehab
Replaces all occurrences of em28xx_write_regs_req() and em28xx_write_reg() used to setup register names by em28xx_write_reg(). Also, documents the register names that are known. This patch were generated by this small perl script: my %reg_map = ( # Register table - the same as defined on parse_em28xx.pl script ); while (<>) { if (m/(.*)em28xx_write_regs_req\(dev\,\s*0x00\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) { my $reg = $2; my $val = $3; $val =~ tr/A-f/a-f/; $reg = $reg_map{$reg} if defined($reg_map{$reg}); printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val; } elsif (m/(.*)em28xx_write_regs\(dev\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) { my $reg = $2; my $val = $3; $val =~ tr/A-f/a-f/; $reg = $reg_map{$reg} if defined($reg_map{$reg}); printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val; } else { print $_; } } Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-12-29V4L/DVB (9754): em28xx: improve debug messagesMauro Carvalho Chehab

2008-12-29V4L/DVB (9753): em28xx: cleanup: saa7115 module auto-detects saa711x typeMauro Carvalho Chehab
Since saa7115 has saa711x chip auto-detection, there's no need on differenciating it at cards table. Just use the generic name for all boards that use a philips saa711x decoder. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9752): Remove duplicated fields on em28xx_board and em28xx structsMauro Carvalho Chehab
Several fields are duplicated on both structs. Let's just copy em28xx_board instead. A later cleanup could just copy the fields that are changed, in order to keep em28xx_board const. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9751): em28xx: card description cleanupsMauro Carvalho Chehab
Remove unused em28xx_board.vchannels and em28xx.video_channels. Also, .is_em2800 = 0 is not needed, as all data is zeroed by kernel loader. The table also included a notice that svideo weren't test on Hauppauge USB2. Remove this notice, since this input also works properly. Also, it does some whitespace cleanups. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9747): em28xx: Properly handles XCLK and I2C speedMauro Carvalho Chehab
The previous patches removed XCLK and I2C magic. Now, we finally know what those registers do. Also, only a very few cards need different setups for those. Instead of keeping the setups for those values inside the per-device hack magic switch, move the uncommon values to the board-specific struct, and have a common setup for all other boards. So, almost 100 lines of hacking magic were removed. A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk were set, without taking any care about not overriding a previous xclk setup.
