2007-10-29[MIPS] Add len and addr validation for MAP_FIXED mappings.David Daney
Mmap with MAP_FIXED was not validating the addr and len parameters. This leads to the failure of GCC's gcc.c-torture/execute/loop-2[fg].c testcases when using the o32 ABI on a 64 bit kernel. These testcases try to mmap 65536 bytes at 0x7fff8000 and then access all the memory. In 2.6.18 and 2.6.23.1 (and likely other versions as well) the kernel maps the requested memory, but since half of it is above 0x80000000 a SIGBUS is generated when it is accessed. This patch moves the len validation above the MAP_FIXED processing so that it is always validated. It also adds validation to the addr parameter for MAP_FIXED mappings.

They break the timer interrupt initialization and only seem to be a kludge for initialization happening in the wrong order. Further testing done by Thiemo confirms the suspicion that the other invocations also seem to have useless. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-10-29[MIPS] txx9tmr clockevent/clocksource driverAtsushi Nemoto
Convert jmr3927_clock_event_device to more generic txx9tmr_clock_event_device which supports one-shot mode. The txx9tmr_clock_event_device can be used for TX49 too if the cp0 timer interrupt was not available. Convert jmr3927_hpt_read to txx9_clocksource driver which does not depends jiffies anymore. The txx9_clocksource itself can be used for TX49, but normally TX49 uses higher precision clocksource_mips.

2007-10-29[MIPS] SMTC: Allow control over TC assignment to vpe0.Kevin D. Kissell
Modify the SMTC initialization code to allow boot-time specification not only of how many VPEs and TCs to use, but also how many TCs out of the allowed pool are to be bound to VPE 0. The new boot option is "vpe0tcs=N", where N is an integer. Using it in combination with the existing options allows arbitrary assignments across the 2 VPEs of a 34K. e.g. "maxtcs=3 vpe0tcs=1" forces VPE0 to have 1 TC, while VPE1 has 2, and "maxtcs=4 vpe0tcs=3" forces VPE0 to have 3 TCs, while VPE1 gets 1. If no vpe0tcs option is specified, the traditional algorithm of evenly dividing TCs between available VPEs, with the odd "slop" going to VPE0, is retained. The reason for doing this is to allow a finer balancing of TCs which can handle I/O interrupts on Malta (those on VPE 0) and those which cannot. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-10-29[libata] AHCI: add hw link power management supportKristen Carlson Accardi
This patch will set the correct bits to turn on Aggressive Link Power Management (ALPM) for the ahci driver. This will cause the controller and disk to negotiate a lower power state for the link when there is no activity (see the AHCI 1.x spec for details). This feature is mutually exclusive with Hot Plug, so when ALPM is enabled, Hot Plug is disabled. ALPM will be enabled by default, but it is settable via the scsi host syfs interface. Possible settings for this feature are: Setting Effect ---------------------------------------------------------- min_power ALPM is enabled, and link set to enter lowest power state (SLUMBER) when idle Hot plug not allowed. max_performance ALPM is disabled, Hot Plug is allowed medium_power ALPM is enabled, and link set to enter second lowest power state (PARTIAL) when idle. Hot plug not allowed. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2007-10-29[libata] Link power management infrastructureKristen Carlson Accardi
Device Initiated Power Management, which is defined in SATA 2.5 can be enabled for disks which support it. This patch enables DIPM when the user sets the link power management policy to "min_power". Additionally, libata drivers can define a function (enable_pm) that will perform hardware specific actions to enable whatever power management policy the user set up for Host Initiated Power management (HIPM). This power management policy will be activated after all disks have been enumerated and intialized. Drivers should also define disable_pm, which will turn off link power management, but not change link power management policy. Documentation/scsi/link_power_management_policy.txt has additional information. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2007-10-29fix abuses of ptrdiff_tAl Viro
Use of ptrdiff_t in places like - if (!access_ok(VERIFY_WRITE, u_tmp->rx_buf, u_tmp->len)) + if (!access_ok(VERIFY_WRITE, (u8 __user *) + (ptrdiff_t) u_tmp->rx_buf, + u_tmp->len)) is wrong; for one thing, it's a bad C (it's what uintptr_t is for; in general we are not even promised that ptrdiff_t is large enough to hold a pointer, just enough to hold a difference between two pointers within the same object). For another, it confuses the fsck out of sparse. Use unsigned long or uintptr_t instead. There are several places misusing ptrdiff_t; fixed.
