2009-09-23BUILD_BUG_ON(): fix it and a couple of bogus uses of itJan Beulich
gcc permitting variable length arrays makes the current construct used for BUILD_BUG_ON() useless, as that doesn't produce any diagnostic if the controlling expression isn't really constant. Instead, this patch makes it so that a bit field gets used here. Consequently, those uses where the condition isn't really constant now also need fixing. Note that in the gfp.h, kmemcheck.h, and virtio_config.h cases MAYBE_BUILD_BUG_ON() really just serves documentation purposes - even if the expression is compile time constant (__builtin_constant_p() yields true), the array is still deemed of variable length by gcc, and hence the whole expression doesn't have the intended effect.

2009-09-10TPM: Fixup boot probe timeout for tpm_tis driverJason Gunthorpe
When probing the device in tpm_tis_init the call request_locality uses timeout_a, which wasn't being initalized until after request_locality. This results in request_locality falsely timing out if the chip is still starting. Move the initialization to before request_locality. This probably only matters for embedded cases (ie mine), a BIOS likely gets the TPM into a state where this code path isn't necessary.

2009-05-20TPM: get_event_name stack corruptionEric Paris
get_event_name uses sprintf to fill a buffer declared on the stack. It fills the buffer 2 bytes at a time. What the code doesn't take into account is that sprintf(buf, "%02x", data) actually writes 3 bytes. 2 bytes for the data and then it nul terminates the string. Since we declare buf to be 40 characters long and then we write 40 bytes of data into buf sprintf is going to write 41 characters. The fix is to leave room in buf for the nul terminator.

"Lots of device drivers register a 'struct device_driver' with the '.bus' member set to '&platform_bus_type'. This is wrong, since the platform_bus functions expect the 'struct device_driver' to be wrapped up in a 'struct platform_driver' which provides some additional callbacks (like suspend_late, resume_early).

2008-10-16tpm: work around bug in Broadcom BCM0102 chipsetValdis Kletnieks
Patch tpm-correct-tpm-timeouts-to-jiffies-conversion reveals a bug in the Broadcom BCM0102 TPM chipset used in the Dell Latitude D820 - although most of the timeouts are returned in usecs as per the spec, one is apparently returned in msecs, which results in a too-small value leading to a timeout when the code treats it as usecs. To prevent a regression, we check for the known too-short value and adjust it to a value that makes things work.

2008-10-16tpm: correct tpm timeouts to jiffies conversionMarcin Obara
This patch fixes timeouts conversion to jiffies, by replacing msecs_to_jiffies() calls with usecs_to_jiffies(). According to TCG TPM Specification Version 1.2 Revision 103 (pages 166, 167) TPM timeouts and durations are returned in microseconds (usec) not in miliseconds (msec). This fixes a long hang while loading TPM driver, if TPM chip starts in "Idle" state instead of "Ready" state. Without this patch - 'modprobe' may hang for 30 seconds or more.

There is no "PNPACPI" driver interface as such. PNPACPI is an internal backend of PNP, and drivers just use the generic PNP interface. The drivers should depend on CONFIG_PNP, not CONFIG_PNPACPI. tpm_nsc.c doesn't use PNP at all, so we can just remove the dependency completely. It probably *should* use PNP to discover the device, but until it does, there's no point in depending on PNP.
