Hi,
These patches switch early memory management to use memblock directly
without any bootmem compatibility wrappers. As the result both bootmem and
nobootmem are removed.
The patchset survived allyesconfig builds on arm, arm64, i386, mips, nds32,
parisc, powerpc, riscv, s390 and x86 and most of
MIPS already has memblock support and all the memory is already registered
with it.
This patch replaces bootmem memory reservations with memblock ones and
removes the bootmem initialization.
Since memblock allocates memory in top-down mode, we ensure that memblock
limit is max_low_pfn to prevent
All achitectures select NO_BOOTMEM which essentially becomes 'Y' for any
kernel configuration and therefore it can be removed.

The __alloc_bootmem_node_nopanic() attempts to allocate memory for a
specified node. If the allocation fails it then retries to allocate memory
from any node. Upon success, the allocated memory is set to 0.
The memblock_alloc_try_nid_nopanic() does exactly the same thing and can be
used instead.

__alloc_bootmem_nopanic(size, PAGE_SIZE, BOOTMEM_LOW_LIMIT) which allocates

This is a repost of the SLB conversion to C, no real change since last
post. But given that slows down the SLB miss handler, I promised some
optimisations could be made to mitigate that.
The two main optimisations after the C conversion are the SLB alloation
bitmaps, and the preload cache.
Thanks
This causes SLB alloation to start 1 beyond the start of the SLB.
There is no real problem because after it wraps it stats behaving
properly, it's just surprisig to see when looking at SLB traces.

When switching processes, currently all user SLBEs are cleared, and a
few (exec_base, pc, and stack) are preloaded. In trivial testing with
small apps, this tends to miss the heap and low 256MB segments, and it

The purpose of this patch series is:
1. We can easily add/modify/delete system call by changing entry
in syscall.tbl file. No need to manually edit many files.
2. It is easy to unify the system call implementation across all
the architectures.
The system call tables are in different format in
__NR_syscalls macro holds the number of system call exist in POWERPC
architecture. This macro is currently the part of asm/unistd.h file.
We have to change the value of __NR_syscalls, if we add or delete a
system call.
One of the patch in this patch series has a script which will generate
a uapi h
The system call tables are in different format in all
architecture and it will be difficult to manually add or
modify the system calls in the respective files. To make
it easy by keeping a script and which'll generate the
header file and syscall table file so this change will
unify them across all
System call table generation script must be run to generate
