Hello,
This the sixth version of the series adding support for the SDHCI

VFS uses f2fs_lookup() to decide f2fs_add_link() call during file creation.
But, if there is a race condition, f2fs_add_link() can be called multiple
times, resulting in multiple dentries with a same name. This patches fixes
it by adding __f2fs_find_entry() in f2fs_add_link() path.

PTP core was creating some attributes, such as "period" and "fifo", and the
entire "pins" attribute group, after creating class deevice, which creates
a race for userspace: uevent may arrive before all attributes are created.
This series of patches switches PTP to use is_visible() to control
visib
Instead of creating selected attributes after the device is created (and
after userspace potentially seen uevent), lets use attribute group
is_visible() method to control which attributes are shown. This will allow
us to create all attributes (except "pins" group, which will be taken care
of later)
kcalloc is more semantically correct when allocating arrays of objects, and
overflow-safe.

To fix 32-bit mmap() syscall returning pointer higher than 4Gb in
64-bit binaries, two mmap bases will be used: one for mapping with
32-bit syscalls and another for 64-bit syscall.
To correctly place those two bases, introduce arch_rnd() function,
which will return the random factor independently o
mmap() uses base address, from which it starts to look for a free space
for allocation. At this moment there is one mm->mmap_base, which is
calculated during exec(). The address depends on task's size, set rlimit
for stack, ASLR randomization. As task size and number of random bits
differ between 6
This test calls 32-bit mmap() through int 0x80 and checks /proc/self/maps
for allocated VMA's address - it should be downer than 4 Gb. Just
accessing allocated with mmap pointer will not work, as we could have
some VMA placed on the same address as lower 4 bytes of the new mapping.
As allocation is
There are a couple of fixes related to x86 mmap():
o 1-2 are just preparation to introduce new mmap bases
o 3 fixes 32-bit syscall returning address over 4Gb in applications,
launched from 64-bit binaries. This is done by introducing new bases:
mmap_compat_base and mmap_compat_legacy_base.
Th
To correctly handle 32-bit and 64-bit mmap() syscalls, we need different
mmap bases to start allocation from. So, introduce mmap_legacy_base()
helper and change mmap_base() to return base address according to
specified task size.
It'll prepare the mmap base computing code for splitting mmap_base
on
Result of mmap() calls with MAP_32BIT flag at this moment depends
on thread flag TIF_ADDR32, which is set during exec() for 32-bit apps.
It's broken as the behavior of mmap() shouldn't depend on exec-ed
application's bitness. Instead, it should check the bitness of mmap()
syscall.
How it worked bef
Let's switch to using device_create_with_groups(), which will allow us to
create "pins" attribute group together with the rest of ptp device
attributes, and before userspace gets notified about ptp device creation.

Allow kprobes to be placed on ftrace _mcount() call sites. This
optimization avoids the use of a trap, by riding on ftrace
infrastructure.
This depends on HAVE_DYNAMIC_FTRACE_WITH_REGS which depends on
MPROFILE_KERNEL, which is only currently enabled on powerpc64le with
newer toolchains.
Based on
KPROBES_ON_FTRACE avoids much of the overhead with regular kprobes as it
eliminates the need for a trap, as well as the need to emulate or
single-step instructions.
Though OPTPROBES provides us with similar performance, we have limited
optprobes trampoline slots. As such, when asked to probe at a
kprobe_lookup_name() is specific to the kprobe subsystem and may not
always return the function entry point (in a subsequent patch). For
looking up function entry points, introduce a separate helper and use
the same in optprobes.c
