2011-01-24can: at91_can: make can_id of mailbox 0 configurableMarc Kleine-Budde2-7/+108
Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in "AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the contents of mailbox 0 may be send under certain conditions (even if disabled or in rx mode). The workaround in the errata suggests not to use the mailbox and load it with an unused identifier. This patch implements the second part of the workaround. A sysfs entry "mb0_id" is introduced. While the interface is down it can be used to configure the can_id of mailbox 0. The default value id 0x7ff. In order to use an extended can_id add the CAN_EFF_FLAG (0x80000000U) to the can_id. Example: - standard id 0x7ff: echo 0x7ff > /sys/class/net/can0/mb0_id - extended id 0x1fffffff: echo 0x9fffffff > /sys/class/net/can0/mb0_id Signed-off-by: Marc Kleine-Budde <[email protected]> Acked-by: Wolfgang Grandegger <[email protected]> Acked-by: Kurt Van Dijck <[email protected]> For the Documentation-part: Acked-by: Wolfram Sang <[email protected]>
2011-01-24can: at91_can: don't use mailbox 0Marc Kleine-Budde1-12/+20

The workaround in the errata suggests not to use the mailbox and load it with a unused identifier. This patch implements the first part of the workaround, it updates AT91_MB_RX_NUM and AT91_MB_RX_FIRST (and the inline documentation) so that mailbox 0 stays unused.

2011-01-24can: at91_can: clean up usage of AT91_MB_RX_FIRST and AT91_MB_RX_NUMMarc Kleine-Budde1-8/+10
This patch cleans up the usage of two macros which specify the mailbox usage. AT91_MB_RX_FIRST and AT91_MB_RX_NUM define the first and the number of RX mailboxes. The current driver uses these variables in an unclean way; assuming that AT91_MB_RX_FIRST is 0; This patch cleans up the usage of these macros, no longer assuming AT91_MB_RX_FIRST == 0.

2011-01-24sched: Fix poor interactivity on UP systems due to group scheduler nice tune bugYong Zhang1-25/+53
Michael Witten and Christian Kujau reported that the autogroup scheduling feature hurts interactivity on their UP systems. It turns out that this is an older bug in the group scheduling code, and the wider appeal provided by the autogroup feature exposed it more prominently. When on UP with FAIR_GROUP_SCHED enabled, tune shares only affect tg->shares, but is not reflected in tg->se->load. The reason is that update_cfs_shares() does nothing on UP. So introduce update_cfs_shares() for UP && FAIR_GROUP_SCHED. This issue was found when enable autogroup scheduling was enabled, but it is an older bug that also exists on cgroup.cpu on UP.

2011-01-24BUILD_BUG_ON: make it handle more casesRusty Russell1-6/+27
BUILD_BUG_ON used to use the optimizer to do code elimination or fail at link time; it was changed to first the size of a negative array (a nicer compile time error), then (in 8c87df457cb58fe75b9b893007917cf8095660a0) to a bitfield. This forced us to change some non-constant cases to MAYBE_BUILD_BUG_ON(); as Jan points out in that commit, it didn't work as intended anyway. bitfields: needs a literal constant at parse time, and can't be put under "if (__builtin_constant_p(x))" for example. negative array: can handle anything, but if the compiler can't tell it's a constant, silently has no effect. link time: breaks link if the compiler can't determine the value, but the linker output is not usually as informative as a compiler error. If we use the negative-array-size method *and* the link time trick, we get the ability to use BUILD_BUG_ON() under __builtin_constant_p() branches, and maximal ability for the compiler to detect errors at build time. We also document it thoroughly. Signed-off-by: Rusty Russell <[email protected]> Cc: Jan Beulich <[email protected]> Acked-by: Hollis Blanchard <[email protected]>

2011-01-24module: show version information for built-in modules in sysfsDmitry Torokhov3-11/+88
Currently only drivers that are built as modules have their versions shown in /sys/module/<module_name>/version, but this information might also be useful for built-in drivers as well. This especially important for drivers that do not define any parameters - such drivers, if built-in, are completely invisible from userspace. This patch changes MODULE_VERSION() macro so that in case when we are compiling built-in module, version information is stored in a separate section. Kernel then uses this data to create 'version' sysfs attribute in the same fashion it creates attributes for module parameters.

commit 3f0d3d016d89a5efb8b926d4707eb21fa13f3d27 adds a check for PNP device id to the common tpm_tis_init() function, which in some cases (force=1) will be called without the device being a member of a pnp_dev.

2011-01-24TPM: Long default timeout fixRajiv Andrade1-4/+6
If duration variable value is 0 at this point, it's because chip->vendor.duration wasn't filled by tpm_get_timeouts() yet.

2011-01-21perf: perf_event_exit_task_context: s/rcu_dereference/rcu_dereference_raw/Oleg Nesterov1-1/+1
In theory, almost every user of task->child->perf_event_ctxp[] is wrong. find_get_context() can install the new context at any moment, we need read_barrier_depends(). dbe08d82ce3967ccdf459f7951d02589cf967300 "perf: Fix find_get_context() vs perf_event_exit_task() race" added rcu_dereference() into perf_event_exit_task_context() to make the precedent, but this makes __rcu_dereference_check() unhappy. Use rcu_dereference_raw() to shut up the warning.

2011-01-21rtlwifi: Fix possible NULL dereferenceJesper Juhl1-2/+9
In drivers/net/wireless/rtlwifi/pci.c::_rtl_pci_rx_interrupt() we call dev_alloc_skb(), which may fail and return NULL, but we do not check the returned value against NULL before dereferencing the returned pointer. This may lead to a NULL pointer dereference which means we'll crash - not good. In a separate call to dev_alloc_skb(), the debug level is changed so that the failure message will always be logged.
