Linus Torvalds authored
Ian Campbell noticed that since "Eliminate thousands of warnings with gcc 3.2 build" (commit 57adc4d2) all WARN_ON()'s currently appear to come from warn_slowpath_null(), eg: WARNING: at kernel/softirq.c:143 warn_slowpath_null+0x1c/0x20() because now that warn_slowpath_null() is in the call path, the __builtin_return_address(0) returns that, rather than the place that caused the warning. Fix this by splitting up the warn_slowpath_null/fmt cases differently, using a common helper function, and getting the return address in the right place. This also happens to avoid the unnecessary stack usage for the non-stdargs case, and just generally cleans things up. Make the function name printout use %pS while at it.

Fix the clkdev API support for the ep93xx uart clocks. The uarts available in the ep93xx have individual clock controls. The current implementation assumes that the bootloader has enabled the clocks before the kernel has booted. It also assumes that the bootloader has set the UARTBAUD bit indicating that the uarts are running off the 14.7456MHz external crystal. This fixes both issues. It also allows the uart clocks to be stopped when there are no users.

The OMAP3430ES2_SAVEANDRESTORE_SHIFT macro is used by powerdomain code in "1 << OMAP3430ES2_SAVEANDRESTORE_SHIFT" manner, but the definition was also (1 << 4), meaning we actually modified bit 16. So the definition needs to be 4. This fixes also a cold reset HW bug in OMAP3430 ES3.x where some of the efuse bits are not isolated during wake-up from off mode. This can cause randomish cold resets with off mode. Enabling the USBTLL hardware SAVEANDRESTORE causes the core power up assert to be delayed in a way that we will not get faulty values when boot ROM is reading the unisolated registers.

Processor idle power states C2 and C3 stop the TSC on many machines. Linux recognizes this situation and marks the TSC as unstable: Marking TSC unstable due to TSC halts in idle But if those same machines are booted with "processor.max_cstate=1", then there is no need to validate C2 and C3, and no need to disable the TSC, which can be reliably used as a clocksource.

A previous 2.6.30 patch, a71e4917, (ACPI: idle: mark_tsc_unstable() at init-time, not run-time) erroneously disabled the TSC on systems that did not actually have valid deep C-states. Move the check after the deep-C-states are validated, via new helper, tsc_check_state(), hich replaces tsc_halts_in_c().

In 2.6.29, 31878dd8 "ACPI: remove BM_RLD access from idle entry path" moved BM_RLD initialization to init-time from run time. But we discovered that some BIOS do not restore BM_RLD after suspend, causing device errors on C3 and C4 after resume. So now the kernel restores BM_RLD. http://bugzilla.kernel.org/show_bug.cgi?id=13032Signed-off-by: Len Brown <len.brown@intel.com>

This patch provides new heuristics for parsing both the form factor and media rotation rate ATA IDENFITY words. The reported ATA version must be 7 or greater and the device must return values defined as valid in the standard. Only then are the characteristics reported to SCSI via the VPD B1 page. This seems like a reasonable compromise to me considering that we have been shipping several kernel releases that key off the rotation rate bit without any version checking whatsoever. With no complaints so far. Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
