2010-02-19[SCSI] libsrp: fix bug in ADDITIONAL CDB LENGTH interpretationBart Van Assche
Fix a bug in the interpretation of the ADDITIONAL CDB LENGTH (add_cdb_len) field of SRP_CMD requests. According to the SRP specification, the layout of this single-byte field is as follows: * Bits 0 and 1 are reserved. * Bits 2 to 7 represent the ADDITIONAL CDB LENGTH field, symbolically represented as n. * Still according to the SRP specification, the ADDITIONAL CDB section takes 4*n bytes. Currently libsrp is only used by the ibmvscsi driver. Since the ibmvscsi driver doesn't support large CDB's, this bug hasn't caused any problems yet.

2010-02-19ACPI: Fix regression where _PPC is not read at boot even when ignore_ppc=0Darrick J. Wong
Earlier, Ingo Molnar posted a patch to make it so that the kernel would avoid reading _PPC on his broken T60. Unfortunately, it seems that with Thomas Renninger's patch last July to eliminate _PPC evaluations when the processor driver loads, the kernel never actually reads _PPC at all! This is problematic if you happen to boot your non-T60 computer in a state where the BIOS _wants_ _PPC to be something other than zero. So, put the _PPC evaluation back into acpi_processor_get_performance_info if ignore_ppc isn't 1. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: Len Brown <len.brown@intel.com>

constant => sizeof conversion. Regression was caused by my commit 6b35ca0d3d586b8ecb8396821af21186e20afaf0 which determined message size using sizeof rather than hardcoded constants. Unfortunately pwc_set_shutter_speed reuses a 2 byte buffer for a one byte message too so the sizeof was bogus in this case. All other uses of sizeof checked and are ok.

I'm trying to fix it on the GCC side (PR43007), but the module is quite stupid in using ULL constants to operate on u32 values: static int apply_frontend_param (struct dvb_frontend* fe, struct dvb_frontend_parameters *param) { ... static const u32 ppm = 8000; u32 spi_bias; ... spi_bias *= 1000ULL; spi_bias /= 1000ULL + ppm/1000; which causes current GCC 4.5 to emit calls to __udivdi3 for i?86 again.

2010-02-18Input: add KEY_RFKILLMatthew Garrett
Most laptops have keys that are intended to toggle all device state, not just wifi. These are currently generally mapped to KEY_WLAN. As a result, rfkill will only kill or enable wifi in response to the key press. This confuses users and can make it difficult for them to enable bluetooth and wwan devices. This patch adds a new keycode, KEY_RFKILL. It indicates that the system should toggle the state of all rfkillable devices.

2010-02-18sh: Merge legacy and dynamic PMB modes.Paul Mundt
This implements a bit of rework for the PMB code, which permits us to kill off the legacy PMB mode completely. Rather than trusting the boot loader to do the right thing, we do a quick verification of the PMB contents to determine whether to have the kernel setup the initial mappings or whether it needs to mangle them later on instead. If we're booting from legacy mappings, the kernel will now take control of them and make them match the kernel's initial mapping configuration. This is accomplished by breaking the initialization phase out in to multiple steps: synchronization, merging, and resizing. With the recent rework, the synchronization code establishes page links for compound mappings already, so we build on top of this for promoting mappings and reclaiming unused slots. At the same time, the changes introduced for the uncached helpers also permit us to dynamically resize the uncached mapping without any particular headaches. The smallest page size is more than sufficient for mapping all of kernel text, and as we're careful not to jump to any far off locations in the setup code the mapping can safely be resized regardless of whether we are executing from it or not.
