However, typically resulting credentials are identical to original ones

Here's a blast from the past. I asked Andi today, and he seems
conceptually okay with this. Could you consider applying it? Aside
from being a bug fix IMO, it will allow my sigreturn test to work
reasonably well as a native 64-bit program.

If the i2c-hid device was runtime suspended and then the system

This patch removes prefixlen from all getxattr/setxattr callsites and
maximum attribute preallocation.
It's an RFC because it could bring a memory leak somewhere if attribute
is stored on the old preallocation basis and I don't know the code enough
to evaluate the risk.

Why don't we start with checking for similar
PER_CPU(old_rsp) usage is simplified - now it is used only
as temp storage, and userspace stack pointer is immediately stored
in pt_regs->sp on syscall entry, instead of being used later,
on syscall exit.
Instead of PER_CPU(old_rsp) and task->thread.usersp, C code
uses pt_regs->sp now.

Please call this hex_dump or something - that's more in line with the
kernel coding style. Please also don't vUse aHungarian nNotation, it's
Before this patch, r11 was saved in pt_regs->r11.
Which looks natural, but requires messy shuffling to/from iret frame
whenever ptrace or e.g. sys_iopl wants to modify flags - because
that's how this register is used by SYSCALL/SYSRET.
This patch saves r11 in pt_regs->flags,
and uses that value fo

The kernel coding style doesn't use Hungarian notation...

These changes make SYSENTER64 code path save flags and user's
stack pointer in pt_regs->flags and pt_regs->sp, where they belong.
As a result, we can drop stub_iopl() and thread_struct::usersp.
Usage of PER_CPU(old_rsp) is reduced to bare minimum.

Some of the CYCLE_ACTIVITY.* events can only be scheduled on
counter 2. Due to a typo Haswell matched those with
INTEL_EVENT_CONSTRAINT, which lead to the events never
matching as the comparison does not expect anything
in the umask too. Fix the typo.
