Both INT (INT n, INT1, INT3, INTO) and UD (UD0, UD1, UD2) serve special purposes in the kernel, e.g., INT3 is used by KGDB and UD2 is involved in LLVM-KCFI instrumentation. At the same time, attaching kprobes on these instructions (particularly UD) will pollute the stack trace dumped in the kernel ring buffer, since the exception is triggered in the copy buffer rather than the original location. Check for INT and UD in can_probe and reject any kprobes trying to attach to these instructions.

Both can_probe and can_boost have int return type but are using int as boolean in their context. Refactor both functions to make them actually return boolean.

Merge tag 'firewire-fixes-6.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire fixes from Takashi Sakamoto: "A workaround to suppress the continuous bus resets in the case that older devices are connected to the modern 1394 OHCI hardware and devices In IEEE 1394 Amendment (IEEE 1394a-2000), the short bus reset is added to resolve the shortcomings of the long bus reset in IEEE 1394-1995. However, it is well-known that the solution is not necessarily effective in the mixing environment that both IEEE 1394-1995 PHY and IEEE 1394a-2000 (or later) PHY exist, as described in section 8.4.6.2 of IEEE 1394a-2000. The current implementation of firewire stack schedules the short bus reset when attempting to resolve the mismatch of gap count in the certain generation of bus topology. It can cause the continuous bus reset in the issued environment. The workaround simply uses the long bus reset instead of the short bus reset. It is desirable to detect whether the issued environment or not. However, the way to access PHY registers from remote note is firstly defined in IEEE 1394a-2000, thus it is not available in the case" * tag 'firewire-fixes-6.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: firewire: core: use long bus reset on gap count error

In commit 19416123 ("block: define 'struct bvec_iter' as packed"), what we need is to save the 4byte padding, and avoid `bio` to spread on one extra cache line. It is enough to define it as '__packed __aligned(4)', as '__packed' alone means byte aligned, and can cause compiler to generate horrible code on architectures that don't support unaligned access in case that bvec_iter is embedded in other structures.

SETUP_RNG_SEED in setup_data is supplied by kexec and should not be reserved in the e820 map. Doing so reserves 16 bytes of RAM when booting with kexec. (16 bytes because data->len is zeroed by parse_setup_data so only sizeof(setup_data) is reserved.) When kexec is used repeatedly, each boot adds two entries in the kexec-provided e820 map as the 16-byte range splits a larger range of usable memory. Eventually all of the 128 available entries get used up. The next split will result in losing usable memory as the new entries cannot be added to the e820 map.

My recent commit e5d00aaa ("selftests/powerpc: Check all FPRs in fpu_preempt") inadvertently broke the fpu_signal test. It needs to take into account that fpu_preempt now loads 32 FPRs, so enlarge darray. Also use the newly added randomise_darray() to properly randomise darray. Finally the checking done in signal_fpu_sig() needs to skip checking f30/f31, because they are used as scratch registers in check_all_fprs(), called by preempt_fpu(), and so could hold other values when the signal is taken.

Chip outputs are enabled[1] before actual reset is performed[2] which might cause pin output value to flip flop if previous pin value was set to 1. Fix that behavior by making sure chip is fully reset before all outputs are enabled. Flip-flop can be noticed when module is removed and inserted again and one of the pins was changed to 1 before removal. 100 microsecond flipping is noticeable on oscilloscope (100khz SPI bus). For a properly reset chip - output is enabled around 100 microseconds (on 100khz SPI bus) later during probing process hence should be irrelevant behavioral change.

Nouveau deallocates a few buffers post GPU init which are required for GPU suspend/resume to function correctly. This is likely not as big an issue on systems where the NVGPU is the only GPU, but on multi-GPU set ups it leads to a regression where the kernel module errors and results in a system-wide rendering freeze. This commit addresses that regression by moving the two buffers required for suspend and resume to be deallocated at driver unload instead of post init.
