* V4L/DVB (7751): ir-kbd-i2c: Save a temporary memory allocation in ir_probeJean Delvare2008-04-26
| | | | | | | | Using i2c_transfer instead of i2c_master_recv in ir_probe saves a temporary memory allocation. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (7750): au0828/ cleanups and fixesAdrian Bunk2008-04-26
| | | | | | | | | | | | | | | | This patch contains the following cleanups and fixes: - "debug" is definitely not a good name for a global variable, renamed it to "au0828_debug" this fixes a compile error with some kernel configurations - since the module parameter is int the variable shouldn't be unsigned - remove the {usb,bridge,i2c}_debug module parameters since they are already covered by the "debug" module parameter - remove the unused au0828_bcount - make the needlessly global i2c_scan static - make the needlessly global dvb_register() static Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (7748): tuner-core: some adjustments at tuner logs, if debug enabledMauro Carvalho Chehab2008-04-26
| | | | | | | | | | | | | | | | | | | | set_addr log were almost useless: discarded SET_TYPE_ADDR commands weren't reported. This patch changed set_addr printk to print a message only if set_addr is wrong. It also fix printk at set_type, since, if an attach were failing, nothing were reported. With the current code, working or not, a call to set_addr will produce a debug printk. also, set_type() were producing a false error message on tuner_xc2028, since it were requesting for setting a frequency on a place where firmware name weren't set yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 'file' argument is unused; lose it. * move setting flags from the caller (dupfd()) to locate_fd(); pass cloexec flag as new argument. Note that files_fdtable() that used to be in dupfd() isn't needed in the place in locate_fd() where the moved code ends up - we know that ->file_lock hadn't been dropped since the last time we calculated fdt because we can get there only if expand_files() returns 0 and it doesn't drop/reacquire in that case. * move getting/dropping ->file_lock into locate_fd(). Now the caller doesn't need to do anything with files_struct *files anymore and we can move that inside locate_fd() as well, killing the struct files_struct * argument. At that point locate_fd() is extremely similar to get_unused_fd_flags() and the next patches will merge those two. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * let unshare_files() give caller the displaced files_struct * don't bother with grabbing reference only to drop it in the caller if it hadn't been shared in the first place * in that form unshare_files() is trivially implemented via unshare_fd(), so we eliminate the duplicate logics in fork.c * reset_files_struct() is not just only called for current; it will break the system if somebody ever calls it for anything else (we can't modify ->files of somebody else). Lose the task_struct * argument. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
| * [PATCH] sanitize handling of shared descriptor tables in failing execve()Al Viro2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | * unshare_files() can fail; doing it after irreversible actions is wrong and de_thread() is certainly irreversible. * since we do it unconditionally anyway, we might as well do it in do_execve() and save ourselves the PITA in binfmt handlers, etc. * while we are at it, binfmt_som actually leaked files_struct on failure. As a side benefit, unshare_files(), put_files_struct() and reset_files_struct() become unexported. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| * | [POWERPC] Add CONFIG_PPC_PSERIES_DEBUG to enable debugging for platforms/pseriesMichael Ellerman2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a DEBUG config setting which turns on all (most) of the debugging under platforms/pseries. To have this take effect we need to remove all the #undef DEBUG's, in various files. We leave the #undef DEBUG in platforms/pseries/lpar.c, as this enables debugging printks from the low-level hash table routines, and tends to make your system unusable. If you want those enabled you still have to turn them on by hand. Also some of the RAS code has a DEBUG block which causes a functional change, so I've keyed this off a different (non-existant) debug #define. This is only enabled if you have PPC_EARLY_DEBUG enabled also. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

In pseries/rtasd.c add "rtasd" to some messages to make it clear where they're coming from. In pseries/scanlog.c remove the hand-rolled runtime debugging support in there.

| * | [POWERPC] Register udbg console early on pseries LPARMichael Ellerman2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On pseries LPAR we can call the udbg routines, and the udbg console very early. So mark the udbg console as safe to call early in boot, and register the udbg console as soon as the udbg routines are hooked up. This allows platforms/pseries code to use printk() and pr_debug() rather than needing to call udbg_printf() directly for early debugging. This is nice because a) it's standard, b) it goes via the printk buffer, and c) you can get printk time stamps.

| * | [POWERPC] Set udbg_console index to 0Michael Ellerman2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because the udbg_console has CON_ENABLED set, it's possible that when we register it with the console code the index won't be set. This leads to slightly confusing boot messages like: [ 0.000000] console [udbg-1] enabled We could remove CON_ENABLED, but we don't want to do that, we always want the udbg console to be activated, even if the user specified some other console on the command line. The simplest fix seems to be just to set the index to 0 by hand. There is no issue with duplicate udbg consoles, as we guard against registering multiple times in register_early_udbg_console().

| * | [POWERPC] Make iSeries spin on __secondary_hold_spinloop, like pSeriesTony Breeds2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently all iSeries secondary CPUs spin directly on the cpu_start field in their paca. Make them spin on the global __secondary_hold_spinloop until after the pacas have been initialised. As Stephen Rothwell points out, this works at the moment because __secondary_hold_spinloop is being set already, but iSeries isn't looking at it :) Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> Acked-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

| * | [POWERPC] Discourage people from fiddling with kernel data from prom_initMichael Ellerman2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As BenH said the other day, it is an "accident" that prom_init.o is linked with the rest of the kernel. The truth is a little more subtle, prom_init isn't truly bootloader, it does access kernel data in a few places. What we can do is discourage people from adding new code that accesses data outside of prom_init. And hence this patch; from the script: # This script checks prom_init.o to see what external symbols it # is using, if it finds symbols not in the whitelist it returns # an error. The point of this is to discourage people from # intentionally or accidentally adding new code to prom_init.c # which has side effects on other parts of the kernel.
