With INIT_STACK_ALL_PATTERN or INIT_STACK_ALL_ZERO enabled the kernel will
be compiled with -ftrivial-auto-var-init=<...> which causes initialization
of stack variables at function entry time.

In order to avoid the performance impact that comes with this users can use
the "uninitialized" attribute to prevent such initialization.

Therefore provide the __uninitialized macro which can be used for cases
where INIT_STACK_ALL_PATTERN or INIT_STACK_ALL_ZERO is enabled, but only
selected variables should not be initialized.

'-fPIC' as an option to the linker does not do what it seems like it
should. With ld.bfd, it is treated as '-f PIC', which does not make
sense based on the meaning of '-f':

  -f SHLIB, --auxiliary SHLIB Auxiliary filter for shared object symbol table

When building with ld.lld (currently under review in a GitHub pull
request), it just errors out because '-f' means nothing and neither does
'-fPIC':

  ld.lld: error: unknown argument '-fPIC'

'-fPIC' was blindly copied from CFLAGS when the vDSO stopped being
linked with '$(CC)', it should not be needed. Remove it to clear up the
build failure with ld.lld.

Stefan reported a test case fail in libc. The test runs with
randomize_va_space set to zero, i.e. disabled randomization. Additionally,
it runs the program with the dynamic loader. Looking at the failure showed
that the heap was placed right before some pages mapped from the binary.
This made memory allocation fail after a few allocations.

Normally, when address randomization is switched off and the binary is
loaded from the dynamic loader, the kernel places the binary below the
128MB top gap. So the address map would look like this:

3fff7fd1000-3fff7fd2000 r--p 00000000 5e:01 1447115 /lib/ld64.so.1
3fff7fd2000-3fff7ff2000 r-xp 00001000 5e:01 1447115 /lib/ld64.so.1
3fff7ff2000-3fff7ffc000 r--p 00021000 5e:01 1447115 /lib/ld64.so.1
3fff7ffc000-3fff7ffe000 r--p 0002a000 5e:01 1447115 /lib/ld64.so.1
3fff7ffe000-3fff8000000 rw-p 0002c000 5e:01 1447115 /lib/ld64.so.1
3fff8000000-3fff8021000 rw-p 00000000 00:00 0       [heap]
3fffffda000-3ffffffb000 rw-p 00000000 00:00 0       [stack]
3ffffffc000-3ffffffe000 r--p 00000000 00:00 0       [vvar]
3ffffffe000-40000000000 r-xp 00000000 00:00 0       [vdso]

However, commit 1f6b83e5 ("s390: avoid z13 cache aliasing") introduced
a mmap alignment mask of 8MB. With this commit, the memory map now
looks like this:

3fff7f80000-3fff7f81000 r--p 00000000 5e:01 1447115 /lib/ld64.so.1
3fff7f81000-3fff7fa1000 r-xp 00001000 5e:01 1447115 /lib/ld64.so.1
3fff7fa1000-3fff7fab000 r--p 00021000 5e:01 1447115 /lib/ld64.so.1
3fff7fab000-3fff7fad000 r--p 0002a000 5e:01 1447115 /lib/ld64.so.1
3fff7fad000-3fff7faf000 rw-p 0002c000 5e:01 1447115 /lib/ld64.so.1
3fff7faf000-3fff7fd0000 rw-p 00000000 00:00 0       [heap]
3fff7fdc000-3fff8000000 rw-p 00000000 00:00 0
3fffffda000-3ffffffb000 rw-p 00000000 00:00 0       [stack]
3ffffffc000-3ffffffe000 r--p 00000000 00:00 0       [vvar]
3ffffffe000-40000000000 r-xp 00000000 00:00 0       [vdso]

The reason for this placement is that the elf loader loads the binary to
end at mmap_base (0x3fff8000000 on s390). This would result in a start
address of 0x3fff7fd1000, but due to the alignment requirement of 8MB,
mmap chooses 0x3fff7f80000. This causes a gap between the end of the
mapped binary and mmap_base. When the next non-shared and non-file pages
are mapped, mmap searches from top to bottom and the first free space it
finds is the gap which is now present. This leaves only a few pages for
the heap. With enabled address space randomization this doesn't happen
because the binary is mapped to a completely different memory area.

Fix this by disabling the mmap alignment when address space randomization
is disabled. This is in line with what other architectures are doing.

The number of sysfs files to be exported by the PAI device drivers

in the sysfs attribute tree.

Without the fix, older machine generation export counter names
based on paiXXXX_ctrnames static array info, which can be inaccurate,
as this array could also contain newer counter names in the
future.  This ensures proper pai counter sysfs attributes for
both newer generation and older generation processors.

When the device drivers are initialized, a sysfs directory
is created. This contains many attributes which are allocated with
kzalloc(). Should it fail, the memory for the attributes already
created is freed in attr_event_free(). Its second parameter is number
of attribute elements to delete. This parameter is off by one.
When i. e. the 10th attribute fails to get created, attributes
numbered 0 to 9 should be deleted. Currently only attributes
numbered 0 to 8 are deleted.

Pull perf tools fixes from Arnaldo Carvalho de Melo:
 "Vendor events:

   - Intel Alderlake/Sapphire Rapids metric fixes, the CPU type
     ("cpu_atom", "cpu_core") needs to be used as a prefix to be
     considered on a metric formula, detected via one of the 'perf test'
     entries.

  'perf test' fixes:

   - Fix the creation of event selector lists on 'perf test' entries, by
     initializing the sample ID flag, which is done by 'perf record', so
     this fix affects only the tests, the common case isn't affected

   - Make 'perf list' respect debug settings (-v) to fix its 'perf test'
     entry

   - Fix 'perf script' test when python support isn't enabled

   - Special case 'perf script' tests on s390, where only DWARF call
     graphs are supported and only on software events

   - Make 'perf daemon' signal test less racy

  Compiler warnings/errors:

   - Remove needless malloc(0) call in 'perf top' that triggers
     -Walloc-size

   - Fix calloc() argument order to address error introduced in gcc-14

  Build:

   - Make minimal shellcheck version to v0.6.0, avoiding the build to
     fail with older versions

  Sync kernel header copies:

   - stat.h to pick STATX_MNT_ID_UNIQUE

   - msr-index.h to pick IA32_MKTME_KEYID_PARTITIONING

   - drm.h to pick DRM_IOCTL_MODE_CLOSEFB

   - unistd.h to pick {list,stat}mount,
     lsm_{[gs]et_self_attr,list_modules} syscall numbers

   - x86 cpufeatures to pick TDX, Zen, APIC MSR fence changes

   - x86's mem{cpy,set}_64.S used in 'perf bench'

   - Also, without tooling effects: asm-generic/unaligned.h, mount.h,
     fcntl.h, kvm headers"
