2011-01-25drivers/video/bf537-lq035.c: Add missing IS_ERR testJulia Lawall
lcd_device_register may return ERR_PTR, so a check is added for this value before the dereference. All of the other changes reorganize the error handling code in this function to avoid duplicating all of it in the added case. In the original code, in one case, the global variable fb_buffer was set to NULL in error code that appears after this variable is initialized. This is done now in all error handling code that has this property. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier f; @@ f(...) { ... return ERR_PTR(...); } @@ identifier r.f, fld; expression x; statement S1,S2; @@ x = f(...) ... when != IS_ERR(x) ( if (IS_ERR(x) ||...)

2011-01-24drm/i915: Use consistent mappings for OpRegion between ACPI and i915Michael Karcher
The opregion is a shared memory region between ACPI and the graphics driver. As the ACPI mapping has been changed to cachable in commit 6d5bbf00d251cc73223a71422d69e069dc2e0b8d, mapping the intel opregion non-cachable now fails.

2011-01-24TPM: Long default timeout fixRajiv Andrade
If duration variable value is 0 at this point, it's because chip->vendor.duration wasn't filled by tpm_get_timeouts() yet. This patch sets then the lowest timeout just to give enough time for tpm_get_timeouts() to further succeed.

2011-01-23drm/i915: Recognise non-VGA display devicesChris Wilson
Starting with SandyBridge (though possible with earlier hacked BIOSes), the BIOS may initialise the IGFX as secondary to a discrete GPU. Prior, it would simply disable the integrated GPU. So we adjust our PCI class mask to match any DISPLAY_CLASS device. In such a configuration, the IGFX is not a primary VGA controller and so should not take part in VGA arbitration, and the error return from vga_client_register() is expected.

2011-01-21RTC: Properly handle rtc_read_alarm error propagation and fix bugJohn Stultz
In reviewing cases where the virtualized interfaces didn't propagate errors properly, I noticed rtc_read_alarm needed fixing. In doing so I noticed my RTC rework dropped a memset and that the behavior of rtc_read_alarm shouldn't be conditionalized on the alarm.enabled flag (as the alarm may be set, but the irqs may be disabled). So those were corrected as well.

2011-01-21RTC: Propagate error handling via rtc_timer_enqueue properlyJohn Stultz
In cases where RTC hardware does not support alarms, the virtualized RTC interfaces did not have a way to propagate the error up to userland. This patch extends rtc_timer_enqueue so it catches errors from the hardware and returns them upwards to the virtualized interfaces. To simplify error handling, it also internalizes the management of the timer->enabled bit into rtc_timer_enqueue and rtc_timer_remove. Also makes rtc_timer_enqueue and rtc_timer_remove static.

2011-01-21ACPI / PM: Call suspend_nvs_free() earlier during resumeRafael J. Wysocki
It turns out that some device drivers map pages from the ACPI NVS region during resume using ioremap(), which conflicts with ioremap_cache() used for mapping those pages by the NVS save/restore code in nvs.c.

2011-01-21ACPI: Introduce acpi_os_ioremap()Rafael J. Wysocki
Commit ca9b600be38c ("ACPI / PM: Make suspend_nvs_save() use acpi_os_map_memory()") attempted to prevent the code in osl.c and nvs.c from using different ioremap() variants by making the latter use acpi_os_map_memory() for mapping the NVS pages. However, that also requires acpi_os_unmap_memory() to be used for unmapping them, which causes synchronize_rcu() to be executed many times in a row unnecessarily and introduces substantial delays during resume on some systems. Instead of using acpi_os_map_memory() for mapping the NVS pages in nvs.c introduce acpi_os_ioremap() calling ioremap_cache() and make the code in both osl.c and nvs.c use it.

2011-01-21kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.
