2010-02-19hw-breakpoints: Accept breakpoints on NULL addressFrederic Weisbecker
Before we had a generic breakpoint API, ptrace was accepting breakpoints on NULL address in x86. The new API refuse them, without given strong reasons. We need to follow the previous behaviour as some userspace apps like Wine need such NULL breakpoints to ensure old emulated software protections are still working. This fixes a 2.6.32 - 2.6.33-x ptrace regression.

2010-02-19[SCSI] Fix printing of failed 32-byte commandsMartin K. Petersen
Having the large CDB allocation logic in sd.c means that scsi_io_completion does not have access to the command buffer. That in turn causes garbage to be printed when a 32-byte command fails. Move the command printing to sd_done where the command buffer is intact. Clear the command buffer pointer after the extended CDB has been freed. Make scsi_print_command ignore commands with NULL CDB pointers to inhibit printing of garbled command strings. Signed-off-by: Martin K.

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>

Move I2C IR initialization from just after I2C bus setup to right before non-I2C IR initialization.

2010-02-19V4L/DVB: Video : pwc : Fix regression in pwc_set_shutter_speed caused by bad ↵Martin Fuzzey
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.

2010-02-19V4L/DVB: dvb: l64781.ko broken with gcc 4.5Richard Guenther
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.
