      powerpc/kasan: Fix addr error caused by page alignment · 4a7aee96
      Jiangfeng Xiao authored 
      In kasan_init_region, when k_start is not page aligned, at the begin of
for loop, k_cur = k_start & PAGE_MASK is less than k_start, and then
`va = block + k_cur - k_start` is less than block, the addr va is invalid,
because the memory address space from va to block is not alloced by
memblock_alloc, which will not be reserved by memblock_reserve later, it
will be used by other places.

As a result, memory overwriting occurs.

for example:
int __init __weak kasan_init_region(void *start, size_t size)
{
[...]
	/* if say block(dcd97000) k_start(feef7400) k_end(feeff3fe) */
	block = memblock_alloc(k_end - k_start, PAGE_SIZE);
	[...]
	for (k_cur = k_start & PAGE_MASK; k_cur < k_end; k_cur += PAGE_SIZE) {
		/* at the begin of for loop
		 * block(dcd97000) va(dcd96c00) k_cur(feef7000) k_start(feef7400)
		 * va(dcd96c00) is less than block(dcd97000), va is invalid
		 */
		void *va = block + k_cur - k_start;
		[...]
	}
[...]
}

Therefore, page alignment is performed on k_start before
memblock_alloc() to ensure the validity of the VA address.

      powerpc/6xx: set High BAT Enable flag on G2_LE cores · a038a3ff
      Matthias Schiffer authored 
      MMU_FTR_USE_HIGH_BATS is set for G2_LE cores and derivatives like e300cX,
but the high BATs need to be enabled in HID2 to work. Add register
definitions and add the needed setup to __setup_cpu_603.

This fixes boot on CPUs like the MPC5200B with STRICT_KERNEL_RWX enabled
on systems where the flag has not been set by the bootloader already.

      powerpc/64: Set task pt_regs->link to the LR value on scv entry · aad98efd
      Naveen N Rao authored 
      Nysal reported that userspace backtraces are missing in offcputime bcc
tool. As an example:
    $ sudo ./bcc/tools/offcputime.py -uU
    Tracing off-CPU time (us) of user threads by user stack... Hit Ctrl-C to end.

    ^C
	write
	-                python (9107)
	    8

	write
	-                sudo (9105)

	    16

	clock_nanosleep
	-                multipathd (697)
	    3001604

The offcputime bcc tool attaches a bpf program to a kprobe on
finish_task_switch(), which is usually hit on a syscall from userspace.
With the switch to system call vectored, we started setting
pt_regs->link to zero. This is because system call vectored behaves like
a function call with LR pointing to the system call return address, and
with no modification to SRR0/SRR1. The LR value does indicate our next
instruction, so it is being saved as pt_regs->nip, and pt_regs->link is
being set to zero. This is not a problem by itself, but BPF uses perf
callchain infrastructure for capturing stack traces, and that stores LR
as the second entry in the stack trace. perf has code to cope with the
second entry being zero, and skips over it. However, generic userspace
unwinders assume that a zero entry indicates end of the stack trace,
resulting in a truncated userspace stack trace.

Rather than fixing all userspace unwinders to ignore/skip past the
second entry, store the real LR value in pt_regs->link so that there
continues to be a valid, though duplicate entry in the stack trace.

With this change:
    $ sudo ./bcc/tools/offcputime.py -uU
    Tracing off-CPU time (us) of user threads by user stack... Hit Ctrl-C to end.

Commit a9409044 ("powerpc/iommu: Add iommu_ops to report capabilities
and allow blocking domains") broke DLPAR add of PCI devices.

The above added iommu_device structure to pci_controller. During
system boot, PCI devices are discovered and this newly added iommu_device
structure is initialized by a call to iommu_device_register().

During DLPAR add of a PCI device, a new pci_controller structure is
allocated but there are no calls made to iommu_device_register()
interface.

Fix is to register the iommu device during DLPAR add as well.

      powerpc/pseries/papr-sysparm: use u8 arrays for payloads · 8ded03ae
      Nathan Lynch authored 
      Some PAPR system parameter values are formatted by firmware as
nul-terminated strings (e.g. LPAR name, shared processor attributes).
But the values returned for other parameters, such as processor module
info and TLB block invalidate characteristics, are binary data with
parameter-specific layouts. So char[] isn't the appropriate type for
the general case. Use u8/__u8.

 - Add a ASMedia ASM1166 quirk.

   The SATA host controller always reports that it has 32 ports, even
   though it only has six ports. Add a quirk that overrides the value
   reported by the controller (Conrad)

 - Add a ASMedia ASM1061 quirk.

   The SATA host controller completely ignores the upper 21 bits of the
   DMA address. This causes IOMMU error events when a (valid) DMA
   address actually has any of the upper 21 bits set. Add a quirk that
   limits the dma_mask to 43-bits (Lennert)

  Worth mentioning are three regressions. One of the nouveau fixes in

  back the deadlock until I can figure out what should be done properly.
  There was a scheduler regression vs amdgpu which was reported in a few
  places and is now fixed. There was an i915 vs simpledrm problem
  resulting in black screens, that is reverted also.

  I'll be working on a proper nouveau fix, it kinda looks like one of

 "Just one patch this time, adding Andreas Larsson as co-maintainer for
  arch/sparc. He is volunteering to help since David Miller has become
  much less active over the past few years.

  In turn, I'm helping Andreas get set up as a new maintainer, starting
  with the entry in the MAINTAINERS file"

      Pull arm SoC fixes from Arnd Bergmann:
 "There are a couple of devicetree fixes for samsung, riscv/sophgo, and
  for TPM device nodes on a couple of platforms.

  Both the Arm FF-A and the SCMI firmware drivers get a number of code
  fixes, addressing minor implementation bugs and compatibility with
  firmware implementations. Most of these bugs relate to the usage of
  xarray and rwlock structures and are fixed by Cristian Marussi"
